I can't think of one aspect of universal gravitation and black holes that isn't nonsense.
How about the observed phenomena best explained by their presence?

I agree.

Spacetime is not a physical material object. It is an irrational 20th century mathematical concept.

If it is curved then they must be able to tell us what color it is.

What colour is electromagnetism?

Things claimed to be explained by universal gravitation and black holes are better explained by electromagnetism and magnetars. Even by magic and Cinderella's invisible pink unicorns.

Electromagnetism has the beauty of containing all of the colors in the visible light spectrum...:thumbsup:

And you've yet to show this in any way, except to post quotes from philosophers and historians from over a century ago, which only tangentially graze the subject of physics at all.

So what colour is centrifugal force? What colour is elasticity? What colour is shear stress? What colour is hydrostatic pressure?

I wasn't talking to you.

But you are ignoring everything.


Duh. It's so weak that electromagnetism is the dominant force in the universe.
It is weak but masses are large. Again, ask the child to pick up a piece of paper with the magnet.


The universal gravitational constant myth G has no precise value because it is entirely imaginary.

Vila, S.C., Changing Gravitational Constant and White Dwarfs, Astrophysical Journal, Volume 206, Pages 213-214, May 1976

Gillies, G.T., et al., The Newtonian Gravitational Constant: Recent Measurements and Related Studies, Reports on Progress in Physics, Volume 60, Pages 151-225, Feb 1997
The Gillies paper is a long review. I have only quickly read through it at this point but I see nothing in it that justifies your arguments

Gundlach, J.H., and Merkowitz, S.M., Measurement of Newton's Constant Using a Torsion Balance with Angular Acceleration Feedback, General Relativity and Quantum Physics, Aug 2000
From the abstract:
We measured Newton's gravitational constant G using a new torsion balance method. Our technique greatly reduces several sources of uncertainty compared to previous measurements: (1) it is insensitive to anelastic torsion fiber properties; (2) a flat plate pendulum minimizes the sensitivity due to the pendulum density distribution; (3) continuous attractor rotation reduces background noise. We obtain G = (6.674215 +- 0.000092)x10^-11 m^3kg^-1s^-2; the Earth's mass is, therefore, M = (5.972245 +- 0.000082)x10^24 kg and the Sun's mass is M = (1.988435 +- 0.000027)x10^30kg
Fixler, J.B., et al., Atom Interferometer Measurement of the Newtonian Constant of Gravity, Science, Volume 315, Number 5808, Pages 74-77, Jan 2007
I read this paper, it is quite interesting but it does not in any way justify your arguments. Do you understand the concept of precision in measurement. This is a difficult constant to measure. There is some possibility that it may vary with time though that is very controversial. That does NOT make it imaginary.

From the abstract
We measured the Newtonian constant of gravity, G, using a gravity gradiometer based on atom interferometry. The gradiometer measures the differential acceleration of two samples of laser-cooled Cs atoms. The change in gravitational field along one dimension is measured when a well-characterized Pb mass is displaced. Here, we report a value of G = 6.693 × 10–11 cubic meters per kilogram second squared, with a standard error of the mean of ±0.027 × 10–11 and a systematic error of ±0.021 × 10–11 cubic meters per kilogram second squared.

From the legend of figure 4.
Combined results of our measurements agree within statistical uncertainties of each other and of the CODATA value, resulting in G =6.693 × 10–11 ± 0.027 × 10–11 m3/(kg·s2) (statistical error) and 6.693 ± 0.021 × 10–11 m3/(kg·s2)

This number is slightly different from the one i quoted before of 6.673, which is much closer to the value Grundlach reported, but not outside the range of experimental error in the measurement.
Unfortunately for you, the moon falls away from the Earth at the rate of 3.8 centimeters per year.
It is not unfortunate for me in any way. It is just a consequence of tidal dissipation as has been explained to you.

"If it be true that every atom occupies the same volume of space, then gravitation might seem to be an effect depending on the crowdedness of electrons; but when an atom, breaks up into unequal parts, the smaller portion must in that case undergo considerable expansion, and that would be inconsistent with the constancy of gravitation, if it depended on crowdedness: hence I think it more probable that it depends on some interaction between positive and negative electricity, and that it is generated when these two come together, that is whenever an atom of matter is formed." -- Oliver J. Lodge, physicist, 1904
Not sure why you quoted this guy because he is wrong.

All atoms are not the same size, and gravity is not an effect that depends on the crowdedness of electrons. Gravity is related to mass.

You talk a lot about electromagnetism and gravity, but what are your views on the strong and weak nuclear forces?

This part of the article is nonsense.

If I have a spacecraft capable of super light speeds I also have a space craft that can cross an event horizon because it can already summon more than infinite energy.

If I can go any speed I like I can cross event horizons, the curvature of space time is meaningless.
Not true; Any mass needs spacetime in order to move. Past the event horizon and spacetime starts to bend in on itself and thus there is no direction to go to. No time and no space. Even if you had all the power of the universe, you will still go nowhere. Now if you were made up of pure antimatter then that is a different story albeit you would need to be of a mass greater than the black holes in order to have enough anti matter left to survive.:wave:

WRONG!
EARTH HAS 4 CORNER SIMULTANEOUS 4-DAY TIME CUBE IN ONLY 24 HOUR ROTATION!4 CORNER DAYS, CUBES 4 QUAD EARTH- No 1 Day God!

Black holes and universal gravitation are PROVEN because ALL CREATION OCCURS BETWEEN AND AS OPPOSITES. Deniers of this are just one-educated; A HOLOCAUST AND IT IS NIGH UPON YOU. HIRED SICK TEACHERS
ARE PAID TO TEACH YOU EVIL TO
ENSLAVE YOU STUPID AND YOU
NOW POSSESS AN IDIOT CYCLOPIC
MENTALITY. YOU LACK THE BRAINS TO KNOW THAT 4 SIMULTANEOUS DAYS ROTATE IN AN IMAGINARY CUBED EARTH.

Thus sayeth Gene Ray, the world's wisest human.

Actually it is not a matter of technology. All matter is made up of quantum particles and all matter must abide by the fundamental constants that allow for matter to exist. In a singularity; Time is ZERO, and without time, space cannot exist, and thus in the centre of a black hole there is no space time and no amount of technology can change that.

That is the assumption that we must make, but what if we are wrong? All assumptions of what might happen after crossing the event horizon are based on our current understanding, which is limited by our technology at this point.

well, not exactly "assumptions" but based on the current math. too bad Cygnus X-1 is too far away to send a probe to, i'd love me some local instrumental data on that sucker.

I knew assumption was a bad word to use, but it was the word that came to mind at the moment. Fortunately, it seems like every time there is an advancement in technology, there is improved understanding of the unknown which leads to another advancement in technology.

yet another reason why the universe is so grand -- we'll never figure everything out, and so there will never be an excuse for boredom :)

What do we conjecture happens within the singularity itself? It almost seems like "hole" might be literally correct.
In a singularity, logic gets torn apart.

Believers have a half brain, they can't think Opposite of Crap they have been taught.
Simple Logic is above them.


The Word EARTH indicates One, Entity or Singularity, but Earth is not an Entity, for the Half of Earth seen from Space cannot exist without the Opposite Half NOT SEEN - existing only as opposites with a plus & minus zero existence. As an Entity, the Opposites will cancel each other out to nothing. Teaching that Earth is an Entity equates to a Doomsday induced by Educaters upon Humanity.
Earth is not a Singularity, it is composed of Opposites.
