Gravity does exist

In fact, frame dragging is proof of gravity's non-existence.

How do black holes forms if there is no gravity, i doubt it would be by the same mechanism

It's kind of like a very deep hole in the fabric of space-time so steep nothing can escape.  The mechanism still isn't fully understood by physicists.  And I've seen an article recently suggesting that black holes don't even exist.  They certainly don't rely on gravity.

"Kind of like"?

That is horrendous science.

Please describe that better. Like, pretend you're intelligent to give a cogent answer at least.

And tey do rely on gravity. Einstein predicted it, we have observed them.

Wait don't bother. you can't.

Gravity doesn't exist.

Gravitation, which is probably what you mean to say, does.

Black Holes are theoretical objects. A black hole is an object which has such high gravitational pull that not even light can escape. Hence it is black. Which makes it pretty hard to observe directly.

Black Holes may form as the result of the collapse of a very massive star at its death. Just as neutron stars form during a supernova explosion of a very massive star so do black holes. But in the black hole case the initial star was so massive that nothing could stop its gravitational collapse. All the matter of the star's core is crushed to an infinitely small point, a singularity.

How do black holes form solely by what you define as gravitation?

So are they referring to the effects of gravity, or that of gravitation?

The terms gravitation and gravity are mostly interchangeable in everyday use, but in scientific usage a distinction may be made. "Gravitation" is a general term describing the attractive influence that all objects with mass exert on each other, while "gravity" specifically refers to a force that is supposed in some theories (such as Newton's) to be the cause of this attraction. By contrast, in general relativity gravitation is due to spacetime curvatures that cause inertially moving objects to accelerate towards each other.

Gravitation.  From wikipedia:

Obviously the article is targeted at laymen, hence the lack of distinction made.

For intrepid REers: Go to wikipedia, type in "gravity", and take note of what article pops up.  This is the third paragraph.

We only discuss scientifical subjects with the highest degree of seriocity here.

please explain then gravitationally bound galaxy super clusters, frame dragging, black holes and tidal forces if gravity doesn't exist.

if gravity didnt exist wouldnt we be floating? or have an extremely bad sense of balance to which we cant even walk?

Read general relativity for further research.


Now, please explain the bending of light if gravity exists.

Now apply this to a flat earth. There you go.

Space craft. Enough said.

Ummm, by massive objects bending the spacetime around them? gravitation does this too you know.
