From the perspective of general relativity, space is a manifold whose curvature we call gravity. From a quantum mechanical perspective, space is filled with photons traversing it (including those carrying the cosmic background radiation); even in the absence of external radiation, the quantum mechanical vacuum contains fluctuating amounts of energy.Okay, then id like to here your idea of what it is
the two are not the same. If you put a valve on the earth and pumped, it would expand because of the pressure of the air on the crust - both are matter. Space is merely empty space, not matter so again ill ask, how can it expand?
How would you possibly work that out? You surely cannot know what the temperature was at the big bang
and about the theories, i could say it was given off by colliding galaxies, stars, comets, or that it is just something put there by God. All of these could be valid as there is no way to disprove them
WMAP's CMB anisotropies as functions of the movements of the WMAP probe relative to the vacuum, and that the CMB is the temperature of the vacuum, and not a cosmological relic
okay, could you name and/or describe such tests to me
Astronomy By Press Release - News From A Black Hole
Since the force of gravity varies as the square of the inverse distance between objects why not make the ultimate extrapolation and let the distance go to zero? You get a LOT of density. Maybe it goes BOOM! But wait a minute, maybe it goes in the opposite direction and goes MOOB! Whatever. Most astronomers decided anyway that this was the only source that could explain the observed jets and explosions in galaxies. Of course it gets very complicated. Also there are a few annoying details right from the beginning:
1. If you watch a Black Hole form, it takes an infinity of time for something to fall in. So Instead of everything falling in it looks like nothing ever falls in. The orthodox answer is that, well, it comes as close as you want. (But maybe not in a Big Bang Universe that is only 15 billion years old.)
Then again how would you like a black hole of 10 billion solar masses (the mass of a whole galaxy) completely formed only a billion years from the Big Bang beginning? The discoverers spoke freely in the popular press 1 but typically only mentioned in one sentence in the the journal paper as: ...formation of such a high M black hole after ~ 1Gyr is difficult to understand. 2
Accretion processes onto Black Holes are supposed to enable them to radiate high energy X-rays. When X-ray telescopes found strong X-ray sources in galaxies they said, aha, this is too strong to be an X-ray star so it must be a black hole in orbit around a star - a binary with a massive black hole revolving around it. Discovery of these now MASSIVE Black holes was so exciting that innumerable papers have appeared showing the X-ray positions and deep photographs at the positions the objects.
Strangely, when these objects were seen optically no one took spectra in order to see what they actually were. Finally a paper appeared in a referred Journal 3 where the authors showed the spectra of two of them to be that of high redshift quasars! Just to cement the case they looked at previously identified quasar in or close to galaxies and in 24 out of 24 cases the quasars belonged to the class of Ultra Luminous X-ray Sources.
2. This result is a double disaster in that the massive Black Holes turned out to be high redshift quasars, not a Black Hole in a binary star. Perhaps worse, they have been accepted as members of nearby galaxies and therefore cannot be out at the edge of the universe. Bye bye Big Bang and all that fundamental physics. (This result was not put out as a press release.)
What was put out recently as a press release was the observation of X-ray outbursts at the center of a galaxy. This was heralded as gas spinning around a Black Hole 4. This is the classical interpretation of + and - redshifts as orbital velocities instead of opposite ejection velocities. I noticed they say the photons go own in frequency (translation: they are redshifted) by climbing out of the gravitational hole. If so, the lines would be smeared out by gravitational gradients. It sounds to me like good old fashioned intrinsic redshifts.
Ironically, the galaxy is a well known, very active galaxy called NGC 3516. Previously published results 5, reprinted here in Fig. 1, show apparently ejected X-ray sources are really high redshift quasars. Perhaps those quoted in the news story should consider whether they have instead observed ejection of new quasars which are evolving into new galaxies as they travel outward.
Ever more recent press releases report the finding in cosmic microwave background radiation, of cooler spots about one degree radius around supposedly very distant galaxy clusters 6. One of the authors was quoted as saying Our results may ultimately undermine the belief that the Universe is dominated by a cold dark matter particle and even more enigmatic dark energy. Well that is standard closing for many press releases. But seriously, the 1 degree radius agrees with observed quasar families evidentially being ejected from active parent galaxies 6. and example in Fig. 1 here. How does this connect?
Ejections from Black Holes are hypothesized to come about when a star or other object falls splat against the surface of a black hole (or accretion disk). But whole quasars and proto galaxies which evolve into normal galaxies out of the fraction that escapes coherently are too much to ask for. Hence the rejection of Ambarzumian's observational conclusion around 1959 that new galaxies were born out of old galaxies. And thus leading to the importance of ejection of low particle mass seed galaxies which also accounts for the high redshifts 7. It would be natural to think that nearby cool spots on the sky as large as the 1 degree radius observed have something to do with the associations of nearby parent galaxies with evolving quasars and galaxies.
But to get down to the fundamental assumptions involved, I remember an Astrophysics lunch at Cal Tech about 30 years ago. Stephen Hawking sat across the table from several of us who were discussing observations of ejection of new galaxies from the compact nuclei of active galaxies. Nothing of this ever crept into Hawkin's assumptions about Black Holes. Only very recently has he abandoned his dictum that nothing comes out of Black Holes and famously now concedes that a little bit does come out. Meanwhile, in the many intervening years, stunning new evidence has emerged on the White Hole propensities of nature. Its only failure I can see is not getting into the press releases.
SCIENTISTS SPEAK ABOUT THE ORIGIN OF MATTER - 3
Scientists explain why the supposed primary "evidences" for the Big Bang are erroneous theories themselves. There never was a Big Bang, and stars cannot evolve from gas. Here are scientific facts to prove it. Evolutionary theory is a myth; creation science is correct. God created everything; the evidence clearly points to it. This is science vs. evolution—a Creation-Evolution Encyclopedia, brought to you by Creation Science Facts.

An asterisk ( * ) by a name indicates that person is not known to be a creationist. Of over 4,000 quotations in the books this Encyclopedia is based on, only 164 statements are by creationists. You will have a better understanding of the following statements by scientists if you will also read the web page, Origin of Matter.
BACKGROUND RADIATION
Background radiation and the redshift are said to be two primary "evidences" that a Big Bang occurred.
Background radiation does exist. It is a low-level microwave radiation, and is said to be the remnants of the Big Bang. But scientists tell us it does not provide the needed evidence. It is the wrong temperature, there is not enough of it, it does not come from only one direction, and it is much too smooth.
"Perhaps the most significant objection to this cosmology [the Big Bang], stems from the presence of the cosmic background radiation."—*J. Silk, the Big Bang (1979), p. 321.
"The observed cosmic microwave background radiation, which has a high degree of spatial isotropy . . is generally claimed to be the strongest piece of evidence in support of hot big bang cosmologies by its proponents . . [But] the claim that this radiation lends strong support to hot big bang cosmologies is without foundation."—*Hannes Alfven and *Asoka Mendis, "Interpretation of Observed Cosmic Microwave Background Radiation," in Nature, April 21, 1977, p. 698.
"Cosmologists would like to believe that the universe is homogeneous and isotropic, that it is relatively smooth over-all and the same in all directions . . Our evidence for isotropy [a single-direction radiation source] is the microwave radio radiation, the so-called 3K black-body that pervades space and seems to be a relic of the very beginning of time. It used to seem to be the same in all directions.
"Not anymore. Five or six years ago we began to hear of a possible dipole anisotropy [two-directional source]. Then at the beginning of 1980 came hints of a quadruple anisotropy . . A quadruple anisotropy [radiation coming at us from four directions, each at right angles to the other] has to belong to the substance of the radiation of the universe itself."—Science News, 1981.
"The Big Bang theory includes a microwave background . . but this success is tempered by the fact that it was expected to be between ten and a thousand times more powerful than is actually the case."—*Fred Hoyle, The Intelligent Universe (1983), p. 181.
"The latest data [on background radiation] differ by so much from what theory would suggest as to kill the big bang cosmologies. But now, because the scientific world is emotionally attracted to the big-bang cosmologies, the data is ignored."—*Fred Hoyle, "The Big Bang in Astronomy," in New Scientist, 92 (1981), p. 522.
"Recent measurements of the density fluctuations in the cosmic microwave background radiation show no fluctuations greater than 2.5 parts in 100,000. No galaxy could grow from a fluctuation that small—even in 15 billion years."—*William R. Corliss, Stars, Galaxies, Cosmos (1987), p. 185.
REDSHIFT
The redshift is said to be the other "evidence" that a Big Bang occurred. But this is not true either. There are three possible explanations to the redshift seen in the spectra of more distant stars, Evolutionists declare that the speed (Doppler) redshift theory is the only cause of the spectral redshift. They say this because, if that is true, then the universe is expanding outward—which they say is caused by an earlier Big Bang.
But there are two other causes of redshifts, which have been proven by science, and these better explain the various oddities associated with red shifts: (1) The tired light redshift: Light gradually slows down as it travels over long distances. (2) The gravitational redshift: Light loses energy as it passes the gravitational fields of stars.
"The year after Sirius B was found to have its astonishing properties, Albert Einstein presented his general theory of relativity, which was mainly concerned with new ways of looking at gravity. Einstein's views of gravity led to the prediction that light emitted by a source possessing a very strong gravitational field should be displaced toward the red (the Einstein shift). [Walter S.] Adams, fascinated by the white dwarfs he had found, carried out careful studies of the spectrum of Sirius B [a dwarf star] and found that there was indeed the redshift predicted by Einstein.
"This was a point in favor not only of Einstein's theory but also of the superdensity of Sirius B, for in an ordinary star such as our sun, the redshift effect would be only one thirtieth as great. Nevertheless, in the early 1960's this very small Einstein shift produced by our sun was detected."—*Isaac Asimov, Asimov's New Guide to Science (1984), p. 50.
"[Speed or Doppler redshifts] are caused by recession of one object in relation to another, and are similar to the Doppler effect of a car rapidly driving away and causing the sound heard by an observer to shift from treble to bass . . [In contrast] A gravitational redshift is the shift to longer wavelengths of light passing through a large gravitational field."—*American Institute of Physics, Glossary of Terms Used in Cosmology (1982), pp. 17-18.
"P. LaViolette has compared the tired light cosmology to the sandar [Big Bang-Doppler effect] model of an expanding universe on four different observational tests and has found that on each one the tired-light hypothesis was superior."—*W. Corliss, "Tired Light Revived," Science Frontiers, 47:2 (1986).
"Redshift observations are, of course, crucial to our modern view of the evolution of the cosmos. Usually, it is assumed that the observed redshifts are entirely due to the Doppler effects. If this assumption is incorrect, our cosmology [matter and stellar origins theories] must be drastically revised.
"At least five major classes of observations exist which tend to undermine the Doppler-effect assumption: (1) Laboratory measurements of spectral noninvariance; (2) Astonomical redshifts that can be correlated with large-scale mass distributions; (3) General comparisons between Doppler-redshift (expanding universe) cosmologies and cosmologies based on other redshift phenomena, such as `tired light,' showing the inferiority of the Doppler hypothesis; (4) Observations of redshift differences between objects thought to be at the same distance; and (5) Observations of quantized redshift."—*W.R. Corliss, Stars, Galaxies, Cosmos (1985), p. 148.
"When we observe galaxies with redshifts greater than z=1, the redshift-distance relationship tells us we are seeing stellar systems more than 10 billion light-years away. Since the universe is thought to be 16-18 billion years old, these distant galaxies must be only 6-8 billion years old, for we are looking back into time. The anomaly here is that these young galaxies do not seem much bluer than nearby old galaxies, 16-18 billion years of age. One would expect the younger galaxies to be much hotter [bluer] and more active."—*W.R. Corliss, Stars, Galaxies, Cosmos (1985), p. 185.
"A massive quantity of data has been accumulated for galactic clusters, galaxy pairs, stars, and other objects, primarily by W.G. Tifft and his colleagues. Although the catalogs of data on galaxies is not suspect, the analysis of those data in a way that supports redshift quantification has not been well-received. Supporting studies by other astronomers would generate more confidence in the reality of this phenomenon . .
"In clusters of galaxies the spirals tend to have higher redshifts than the E galaxies."—*Halton Arp, "Three New Cases of Galaxies with Large Discrepant Redshifts," Astrophysical Journal, 230:469 (1980). [This is because the spirals are exerting more gravity on the outflowing light.]
"The concept of an expanding universe hinges on the astrophysicists' assumption that no change occurs to the galaxies' photons on their long, undisturbed trip from the galaxies to us."—Russell Akridge, "The Expanding Universe Theory Is Internally Inconsistent," in Creation Research Society Quarterly, June 1982, p. 56.
"A photon's energy loss is counted twice in the Big Bang expanding universe theory: [1] In the Big Bang theory, free photons must lose most of their original energy as they travel for vast times. [2] In the expanding universe theory, free photons must not lose any energy as they travel for vast times.
"A free photon cannot do both at the same time.
"If a free photon loses energy, the Big Bang theory may [or may not] be correct, but the universe is not expanding. However, if the universe is expanding, free photons do not lose energy, because any photon loss is due to the expansion of the universe . . "If either the Big Bang or the expanding universe is true, the other cannot be true. Yet, they are both part of the same evolutionary scheme. Both must be true for either to be true. Therefore, the Big Bang expanding universe theory is false."—Op. cit., p. 58.
THE HALTON ARP DISCOVERIES
Halton C. Arp, a careful astronomer and astrophysicist, has compiled a remarkable collection of facts which negate acceptance of the speed theory of redshift. But the establishment had him fired for doing so, because his discoveries disprove the expanding universe theory, a primary "evidence" that a Big Bang once occurred.
"The astronomer, Halton Arp, has found enigmatic and disturbing cases where a galaxy and a quasar, or a pair of galaxies, that are in apparent physical association have very different redshifts. Occasionally there seems to be a bridge of gas and dust and stars connecting them. If the redshift is due to the expansion of the universe, very different redshifts imply very different distances."—*Carl Sagan, Cosmos (1980), pp. 255.
"In case the thesis of this book is correct, we want to know what the factors are that led to this long, implacable rejection of new knowledge, the wasted effort, and the retardation of progress."—*Halton Arp, Quasars, Redshifts and Controversies (1987), p. 5.
"There is massive, incontrovertible evidence for important phenomena and processes . . which we cannot currently understand or explain."—*Op. cit., p. 2.
"It is of profound importance to recall now that for a number of classes of . . objects, there was never any shred of evidence that they obeyed a Hubble relation . . The assumption that . . objects obeyed a redshift-distance relation sprang simply from the feeling that if one kind of object [Sb galaxies] did, all objects must do so. Such a generalization is an example of the oldest of logical fallacies. Nevertheless, it has become an article of faith despite many examples of contradictory evidence."—*Op. cit., p. 178.
"As with the statistical association of quasars with galaxies, the implication of physically interacting objects with different redshifts is revolutionary. The redshift distance relationship is a pillar of modern astronomy, and this pillar would be shattered if paired objects had different redshifts."—*W.R. Corliss, Stars, Galaxies, Cosmos (1985), p. 100.
"It cannot be stressed too strongly, however, that these discordant redshifts are not discovered in just one or two isolated cases that have no relation to each other. But in every case we can test—large clusters, groups, companions to nearby galaxies, companions to middle-distance galaxies, companions liked by luminous filaments, galaxies interacting gravitationally, chains of galaxies—in every conceivable case, we come out with the same answer: This same discordant redshifts for the same general class of younger, fainter galaxies."—*H. C. Arp, "Evidence for Discordant Redshifts," in G. Field (ed.), The Redshift Controversy, p. 54.
"This important result has largely been ignored by astonomers because it does not fit in with the current theoretical framework."—*H. Arp, "Further Examples of Companion Galaxies with Discordant Redshifts and Their Spectral Peculiarities," in Astrophysical Journal, 263 (1982), p. 54.
"Twenty-two new quasars close to galaxies are reported. Most of them are so close to companion galaxies that the probability of accidental occurrence is less than 0.01."—*Halton Arp, Quasars near Companion Galaxies, Astrophysical Journal, 250:31 (1981).
"Burbidge and Arp are upset by what they see as a distressingly one-sided approach to the quasar redshift question by the community of astromoners, `Observational evidence exists on both sides,' Burbidge argues, `Both sides are probably right. What is unfortunate . . is the great prejudice in the field. Arp's papers and others—suggesting that some quasars are nearby—are held up, interminably rejected. Heckman's polemic [calling for recantation] would not be published, were it on the other side.'
"If Heckman's call for recantation is meant in such `good humor,' Arp asks angrily, `Why has telescope time been cut off for proponents of the [opposing] viewpoint? . .
" `Much is at stake,' says Burbidge. `If it is accepted that just one large redshift is not due to the universal expansion [expanding universe], Pandora's box is open. Much of our currently claimed knowledge of the extragalactic universe would be at risk, as would a number of scientific reputations.' "—*"Companion Galaxies Match Quasars Redshifts: The Debate Goes On," Physics Today, 37:17, December 1984. [Heckman's statement, calling for recantation by Arp's group, is given in *T.M. Heckman, et. al., "Low-Redshift Quasars, et. al.," Astronomical Journal, 89:958 (1984).]
"Thus, estimates of the size of the observable universe would shrink considerably—perhaps say Wolf, by a factor of 100 or more."—I. Amato, "Spectral Variation on a Universal Theme," Science News 130:166 (1986).
"No matter what they might turn out to be, quasars attracted attention most of all because of their apparent extreme distance from Earth. If they are as far away as redshift measurements seem to indicate, then they are remnants of the universe's very earliest eras and would allow theorists, in effect, to travel back to those epochs.
"Not all astronomers see quasars as time machines, however. A small though vocal minority has argued that since some supposedly distant quasars seem physically associated with relatively nearby galaxies, the redshift rule may not apply universally to all types of extragalactic objects. Striking, as it did, at one of the central pillars of modern cosmology—the redshift evidence of an exploding universe—this hypothesis touched off what had been characterized as one of the most bitter episodes in the history of astronomy.
"At the center of the debate is Halton Arp, the same astronomer who drew up an atlas of peculiar galaxies. Indeed, it was while investigating these extragalactic aberrations that Arp came upon what he believed was evidence for direct ties between some galaxies and quasars. Several Arp photographs show faint bridges apparently linking nearby galaxies with supposedly more distant quasars. Arp therefore argued that the high redshift of these quasars are caused by factors other than distance . .
"The astronomical community reacted harshly and not entirely rationally. Most astronomers dismissed Arp's views out of hand, suggesting that the supposed connections were optical illusions produced by chance alignments. Some even went so far as to impugn his integrity by remarking that most of the evidence of physical associations between objects of different redshifts came from photographs produced by Arp himself. [In which instance, he gave exact locations; the dissidents could verify the evidence if they had wished to do so.]
"A few eminent supporters, including the renowned astrophysicist Geoffrey Burbidge, made impassioned pleas for everyone to keep an open mind, but to no avail. In 1983, Arp was to suffer the indignity of being barred from the tools of his trade. Caltech's telescope allocation committee decided that his line of research was not worthy of support and that he would receive no more time for this work at the telescopes of the Mount Wilson and Palomar observatories.
"Arp refused to take up more conventional studies simply to please the committee; instead, he chose to leave Caltech for a position at the Max Planck Institute in Munich, where he continued to pursue his ideas. Referring to his abrupt and ignoble ouster, Burbidge later wrote, `No responsible scientist I know, including many astronomers who were strongly opposed to Arp's thesis, believes justice was served.' "—*Time-Life, Cosmic Mysteries (1990), pp. 67-68.
"In a photograph by controversial astronomer Halton Arp, a large spiral galaxy located relatively near the Milky Way [our galaxy] and a quasar widely assumed to be a billion light-years more distant appear to be physically linked by a bridge of matter. Arp . . believes that the high redshifts may be caused by something other than increasing distances resulting from the expansion of the universe."—Op. cit., p. 69.
hi all,
PROBLEM NUMBER 1
Firstly, we have an issue with the Big Bang - using data provided by NASA regarding the estimated mass of all visible matter, and Big Bang theory, it is possible to work out what the gravity at point of singularity (Big Bang) would have been:
Proposed mass of Universe 1.59 x 1055kg
The approximate diameter of an atom 10-12cm
= 10-14m
Singularity size (a billionth this size) 10-23m
Therefore, the total gravitational force = 1,07 x 1091 using Newtons law of Universal Gravitation.
PROBLEM NUMBER 2
This deals with the red shift...
If the red shift is valid, all matter in the universe is moving away from us. This is often cited by scientists as proof for the Big Bang.
BUT, according to NASA, our nearest neighbor galaxy, Andromeda, is moving towards us at a phenomenal rate.
This would be due to the gravitational pull of the galaxies on each other.
Wow, busterdog, you sure know how to swamp your opposition. It would take at least two pages just to slog through all those. But the regulars here know that every time you have drilled into something with depth instead of breadth the fringe theories you support have never won.
Nevertheless, one spam deserves another.Here are comments about telescope time and fringe astronomy, from the "Controversies in Astrophysics" open Yale course I recommended. Full transcript here: http://open.yale.edu/courses/astrono...nscript18.html
Heres another question id like to pose on the same topic:
Why would space expand?
If we are going to say that space is NOT defined as emptiness between matter, and that it expands, then there has to be a cause to it.
Please give ur opinions and theories
Space expands because the amount and distribution of energy within it causes it to expand.
the amount of energy will remain constant. Im guessing ur relating "distribution" to entropy?
How would distribution of energy cause "Space" to expand. I think for that, you really need to define space decently.
Heres another thought...
Andromeda is the closest galaxy to us.
Andromeda is moving towards us.
We are therefore moving towards Andromeda at the same rate because the value of F is the same for both masses.
Therefore, if every other mass in the universe was STATIONARY, then we would be moving away from most of them, and the distance would be increasing, and we would observe a Red Shift.
This is shown in the pictures below:
As illustrated, the distances between the milky way and galaxies labelled 1 to 5 have all increased.
Hence, a red shift will be expected when veiwing these 5 objects.
With is information, one could easily conclude that the universe is expanding, given that 5 out of six bodies visible in the sky are geting further away from us.
BUT, the ONLY movements here are between galaxies A and B (A being the milky way, and B being Andromeda).
We are situated at a point in space, and are guided by our observations. Situated at A in the diagrams, we would observe pretty much exactly what we observe here on earth.
In that case, how do you know that the Universe is indeed expanding? I would say the evidence was inconclusive due to the above thought.
I'm especially interested to hear responses to this one
Well all the galaxies and matter behind Andromeda (from our point of view) would appear blue-shifted (to our point of view).
That is we'd see red shifted galaxies in one direction and blue shifted galaxies in the other.
Any galaxy with +- 200 degrees (180 + a few more dependng on their distance from 180-200) wil appear red shifted
Galaxies at a relatively small angle on either side of Andromeda with relation to us will probably appear red-shifted, as the light is passing through an area of comparitively high gravity.
That leaves a fairly small portion of the night sky. If there are indeed galaxies in that direction, they would probably be blue-shifted.
BUT the majority of galaxies (not all) will receive a red shift, which is the case currently.
