I have a question. Why is the big bang theory regarded as fact these days especially in light of simpler theories of the universe which arent event glanced at?
Because it has the most supporting evidence, and has the greatest explanatory power.

Woudlnt Occam's Razor atleast force most people to look at these alternate theories why have dark matter and dark energy if it isnt needed?
Occam's razor says that, all things being equal, the simpler explanation is to be preferred. Another way of wording it is that the simplest explanation is the most likely one, all things being equal.

But that phrase is important: all things being equal. Since the Big Bang theory is far and away superior to any competitor, all things aren't equal, so Occam's razor lies unused.

The general principle of parsimony is an important one, but it only applies when the evidence doesn't favour any particular explanation. In this case, the evidence quite firmly points to the Big Bang.

Then there is the cosmological constant(aka fine tuning) forcing the big bang theory to become even more ridiculous with the multiverse theory and now alien design?
I disagree with that assessment.

See above. The evidence does not firmly point to the Big Bang. I have seen 4 supposed evidences of the big bang according to wikipedia. Atleast 2 of those points are debateable. It seems to me like the correlation between storks and babies in Germany.


I disagree with that assessment.

Go on.

Does this forum have no spoiler tags?


No.

Sorry, but most EU nonsense has all the hallmarks of wingnuttery. The most telling trait is that they avoid peer review by physicists and astronomers. They will make various claims but they cannot back it up by work that is checked out by other physicists and astronomers.

That should tell you something.

Because once theory has taken hold it is almost impossible to change it regardless of the evidence. Look how long it took for flat earth theory to be overturned.

And you must remember that the BB was conceived when astronomers believed this galaxy was the only galaxy in the entire universe, and that everything we could observe was contained within it.

Wrong. And again on several levels.

Theories are overturned all of the time. All that is needed is evidence that the old theory has serious flaws and a new theory which is supported by clear evidence. So far the EU nuts have done neither of these. I freely call them nuts since they do what other nuts do, avoid the scientific method in their "science". Remember that going to the correct peer reviewed journals is only the first step in changing a scientific idea. If a group won't even do that you know their science is bad.

Second the Big Bang Theory was conceived after we knew that the Milky Way was not the only galaxy in the universe. It was formed by measuring how fast other galaxies were retreating from ours.

Tell me how they could have formed the BBT without that knowledge?

The website of the link i posted believes that the universe had no beginning. I think that it is different from the electric universe. As for evidence for the big bang theory. One thing has bothered me. How can this:

http://upload.wikimedia.org/wikiped...c_9yr_moll4096.png/800px-Ilc_9yr_moll4096.png

...can bee seen as uniform radiation. It doesnt look to me to be uniform at all even if you take out the yellow and the red areas for whatever reason.

You just spout nonsense all the time don't you. Your BB theory is not even a scientific theory anymore, it is a religion. A religion that relies upon so many untestable Fairie Dust entities it's worse than creationism in that sense.

Big Bang - Wikipedia, the free encyclopedia

"Georges Lemaître first proposed what became the Big Bang theory in what he called his "hypothesis of the primeval atom". Over time, scientists built on his initial ideas to form the modern synthesis"

Georges Lemaître - Wikipedia, the free encyclopedia

"He was the first person to propose the theory of the expansion of the Universe, widely misattributed to Edwin Hubble.http://en.wikipedia.org/wiki/Georges_Lemaître#cite_note-2http://en.wikipedia.org/wiki/Georges_Lemaître#cite_note-3 He was also the first to derive what is now known as Hubble's law and made the first estimation of what is now called the Hubble constant, which he published in 1927, two years before Hubble's article.http://en.wikipedia.org/wiki/Georges_Lemaître#cite_note-4http://en.wikipedia.org/wiki/Georges_Lemaître#cite_note-5http://en.wikipedia.org/wiki/Georges_Lemaître#cite_note-6http://en.wikipedia.org/wiki/Georges_Lemaître#cite_note-7 Lemaître also proposed what became known as the Big Bang theory of the origin of the Universe, which he called his 'hypothesis of the primeval atom'."

Milky Way Galaxy: Facts About Our Galactic Home | Space.com

"As late as the 1920s, astronomers thought all of the stars in the universe were contained inside of the Milky Way. It wasn't until Edwin Hubble discovered a special star known as a Cepheid variable, which allowed him to precisely measure distances, that astronomers realized that the fuzzy patches once classified as nebula were actually separate galaxies."

But long before you had already settled on expansion due to the false belief that all red shift is caused by recession. Except when they got to be close to fractions of c, you decided that wasn't a good thing, so then along came an expanding spacetime composed of absolutely nothing. You got so much fairie Dust in your theories I am surprised you have the nerve say anythi9ng about creationists belief in unseen and undetectable things. Every single Fairie Dust entity in modern astronomy has never been observed in the laboratory. But everything we observe in space has been observed in the laboratory in relation to plasma, including redshift.

All you have a Fabricated Ad-hoc Inventions Repeatedly Invoked in Effort to Defend Untenable Scientific Theory. Fairie Dust. You have not one laboratory experiment to back up any of your supposed claims, while I can explain every single one by proven laboratory experiments with plasma, the 99% of the universe you and astronomers ignore.

Yes, you will accept extra dimensions, wormholes, neutron stars, dark matter and dark energy, WIMPS, WIMPZillas, strings, black holes, everything never once observed but you wont accept what we observe in space everyday. Electric currents and magnetic fields. You can't explain galactic rotation curves because you ignore what plasma is, an electrified medium and the electric force is 10^39 powers stronger than gravity, more than strong enough to account for these rotation curves with no extra mass needed. Just for you to quit ignoring plasma.

Only an idiot would ignore 99% of the universe and then postulate 96% Fairie Dust as an explanation for the 99% he ignored. You best get used to EU theory, because it is coming in whether you like it or not.

NASA - The Electric Atmosphere: Plasma Is Next NASA Science Target

NASA Mission Discovers Particle Accelerator in Heart of Van Allen Radiation Belts | NASA

And we all know how particle accelerators work don't we.

HowStuffWorks "Particle Accelerator"

"Most particle accelerators use electric fields to accelerate charged particles and magnetic fields to guide them. In general, the electric field can be set up to accelerate either negatively or positively charged particles, including particles of antimatter. A magnetic field exerts a force on moving charged particles in such a way that it acts at right angles to the direction in which the particles are moving. The strength of the magnetic field controls the degree to which the charged particles will curve as they move through the field. The magnetic field can thus be used to make charged particles move in a circular path while the electrical fields are used to boost the energy of the particle to higher and higher levels."

In reality they all use electric fields, even those that work by varying magnetic fields.

Magnetic field - Wikipedia, the free encyclopedia

"Similar to the way that a changing magnetic field generates an electric field, a changing electric field generates a magnetic field. This fact is known as Maxwell's correction to Ampère's law. Maxwell's correction to Ampère's Law bootstrap together with Faraday's law of induction to form electromagnetic waves, such as light. Thus, a changing electric field generates a changing magnetic field, which generates a changing electric field again."

If you could even justify your incorrect beliefs of magnetic fields you might have a prayer, but as it is modern Fairie Dust cosmology is dying a slow death, your astronomers just refuse to let go of their Fairie Dust because there is too much money and prestige looking for nothing, When nothing is found they simply ask for more money to keep looking for more nothing. 25 years the search for Dark Matter has been going, and not once detected.

Big Bang - Wikipedia, the free encyclopedia

Wrong. You proved that you are no judge when it comes to physics. That was the purpose of my little test. It showed that you have no ability to do any physics at all and therefore any of your statements about any aspect of physics is pure uninformed nonsense.

You are projecting your faults upon others. While scientists can explain why they believe there is Dark Matter you cannot explain your belief in "plasma".

It wasn't until Edwin Hubble discovered a special star known as a Cepheid variable, which allowed him to precisely measure distances, that astronomers realized that the fuzzy patches once classified as nebula were actually separate galaxies."

Yes, Hubble finally nailed down the evidence that the nebula outside of our galaxy were other galaxies. He was not the first to think of it. You seem rather ignorant. It looks like you think science is done in a vacuum with no other scientists knowing what the other scientists are working on. That is not the case. That is one of the reasons that professional journals are important. Here this is from one of your sources on LeMait. It is his original name of his paper:

("A homogeneous Universe of constant mass and growing radius accounting for the radial velocity of extragalactic nebulae"

Notice he did it the correct way. It is fairly obvious that he knew that he was tracking large concentrations of stars that were outside of our galaxy. His caution was not to call them galaxies at that time.

But long before you had already settled on expansion due to the false belief that all red shift is caused by recession. Except when they got to be close to fractions of c, you decided that wasn't a good thing, so then along came an expanding spacetime composed of absolutely nothing. You got so much fairie Dust in your theories I am surprised you have the nerve say anythi9ng about creationists belief in unseen and undetectable things. Every single Fairie Dust entity in modern astronomy has never been observed in the laboratory. But everything we observe in space has been observed in the laboratory in relation to plasma, including redshift.

Once again you show that you are totally ignorant of science. How is any of that "fairy dust"? Perhaps you might want to ask a physicist why they came to those decisions. We all know that is what you would do, guess and rely on fairy dust. That is not what physicists do.

No sorry, you can't. The problem with the theory from your side is that people who can do the math were able to find certain features of it that are missing in the real world. Again, talk to a real physicist some time. Don't listen to your friends who are almost as ignorant as you.


I did not read the rest of your garbage.

Again the challenge is simple and fair. Find some peer reviewed articles from an article in a respectable physics or astronomy journal. Until then you and I both know that you have nothing.

All your little test showed was that I have no knowledge of things never once observed in the universe. In other words useless theoretical science.

You still have not explained how knowing the gravity of a hollow sphere inside a solid sphere and non-concentric to that solid sphere is going to be any use to anyone in the real world?

I no more concern myself with nonsense math than I do with nonsense religious ideas.

I know you do not expect me to believe that any planet or star has a hollow sphere non-concentric to its body inside it? Or even a hollow sphere at it's core. So I should concern myself with this useless math for what reason?

Of course those that believe in Fairie Dust Dark Matter and stuff might think it is useful, since they deal in fantasies anyway. But sorry, we live in the real world, not make-believe. Good strawman though.
