Yes, you can use gravity to predict black holes.

That explanation is untestable
and impossible
since you don't know what is GRAVITY
Do you know GRAVITY?
Einstein and me: A black hole has an empty space...
Quote from: MrIntelligentDesign on 23/02/2022 03:41:29That explanation is untestableIt absolutely is testable. The Event Horizon Telescope even confirmed it when it imaged the super-massive black hole at the center of the galaxy Messier 87. The object there is black, just as predicted.Quoteand impossibleObviously not. Your argument is a non-sequitur anyway. A person doesn't have to know what gravity is in order to know things about it. Do you not think that cavemen realized that things fall towards the ground? They knew about gravity, even if they didn't know exactly what it was or what caused it. A caveman can predict that a rock thrown into the air will fall and do so without having to know what gravity is.Quote from: MrIntelligentDesign on 23/02/2022 03:41:29since you don't know what is GRAVITYGravity is the tendency for objects with mass to attract each other.
If yes, can you use GRAVITY to correctly predict a Black Hole?
Sorry, you really do not know gravity. What if there are only two object in the universe, a sun and earth, how could they attract each other if they are very far from each other? Then, where is GRAVITY?
The equivalence principle very elegantly explains gravitational lensing. The equivalence principle basically says that, if you were inside of a room with no windows, you wouldn't be able to tell whether the room was sitting still on the surface of the Earth or whether it was out in space away from a gravity source accelerating upwards at a rate 9.8 m/s/s. No experiment could distinguish between the two scenarios.Now imagine that you have a flashlight held sideways in this upward accelerating room. When you switch the flashlight on, the light beam moves out of the flashlight in a straight line. However, the floor of the room is accelerating upwards toward the light beam. From your own perspective (if your senses were good enough) it would look like the light beam was falling towards the floor.Since the equivalence principle states that the behavior of light in this accelerating room is identical to the behavior of light in a room in a gravitational field, that means the equivalence principle predicts not only that light will bend in a gravitational field, but also how much it will bend.
Acceleration is one part distance and two parts time.
he bending of light is actually connected to the second time vector
The problem physics has created for itself is in not recognizing how gravity and the pressures it generates impacts the phase characteristics of the matter contained.
the layers of the earth; oceans/crust, mantle, inner core and core seem to coordinate with different phases of water.
This has little to do with space-time
second time vector

What if there are only two object in the universe, a sun and earth, how could they attract each other if they are very far from each other? Then, where is GRAVITY?Apparently, I understand gravity better than you do. At least I was aware that gravity obeys the inverse square law (meaning that the strength of attraction varies with the square of the distance). Gravity gets weaker with distance but never goes to zero. This means that the gravitational attraction between two objects always exists, no matter how far apart they are.The inverse square law is one of the most fundamental aspects of gravity. If you didn't know something that basic about gravity, how are you in any position to tell us that we don't understand gravity? Make sure you know what you are talking about before you try lecturing others.
I understood that you knew Newton's gravity but not Einstein's explanation of gravity..
Gravity goes to zero?
Or do you mean equilibrium state of space?.

You really do not know GRAVITY, lol!
Quote from: MrIntelligentDesign on 27/02/2022 00:46:21You really do not know GRAVITY, lol!And what's your evidence for that?
Quote from: MrIntelligentDesign on 27/02/2022 00:46:21You really do not know GRAVITY, lol!I know this will come as a shock, but you are the one who is showing a profound ignorance of physics.
Everything you posted about GRAVITY is not complete...

Quote from: MrIntelligentDesign on 27/02/2022 02:54:18Everything you posted about GRAVITY is not complete...And you expect me to write down everything that is currently known about gravity? That's not feasible.If I've said anything about gravity that is actually incorrect, then please point it out (while supplying evidence that shows I am wrong). I've already pointed out where you have been wrong.
