If you look at the picture on the link provided, you'll see what Einstein discovered. Space and time are linked as spacetime, a fabric-like vacuum
(a perhaps material space). Gravity is the rippling effect that pulls the spacetime fabric towards a given gravitational mass. A black hole takes
this to the extreme by pulling with such a force that the energy of light cannot be propelled in a given direction fast enough to escape once it has
hit the event horizon. Understand, though, that forward velocity, substance, and propagation are all different points to measure. Don't confuse a
speed (velocity) with propagation.
Propagation determines how long it will take a gravitational force to effect its surroundings. In other words, if a star forms a lightyear away from
a planet, and the propagational speed of gravity is the speed of light, it will take one year before that planet feels the effects of the newly formed
star. Technically, light follows the contours of spacetime and that is why light disappears into a blackhole, thus why we call it a "black-"
Think of throwing a stone into a lake and watching the ripples... that's what gravity IS according to general relativity. The velocity that those
ripples are moving at is the propagation, which is NOT the accelerating force that pulls objects towards the gravitational mass. Of course, if there
is a boat in the water, it will sway with the ripples of the waves. For complex reactions (multiple ripples from multiple sources acting on multiple
boats), you must refer to Chaos Theory ... which is an insane compilation of mathematics and scientific discovery.
"is it the speed of gravity or the power of gravity?"
I hope the above answers your question. Power is actually a measurement of work done, while velocity is a measurement of movement over time. The
article is testing for propagational velocities.
"it is the power that pulls the light into the hole not the speed"
Don't use the term "power." What you are referring to is the escape velocity of a gravity well. Yes, that is different than propagation.
"the speed of light increases by the power of gravity, that is why it disappears"
No, the speed of light only changes velocities when going through different mediums/materials. Gravity simply changes the direction of light and then
traps it inside the event horizon. That is why you see a blackhole. The light on the inside of the blackhole cannot overcome the pull to get outside
of it because the escape velocity is too high for the trapped light. Right outside of the event horizon, the gases get superheated and give off
jetstreams in the opposite direction of the blackhole's pull. These galaxies are known as quasars.
"some theorize that there is no gravity
only the force of dark matter [ 70-90 percent of the known universe] exerting pressure as it expands, thats why there are black holes in our known
universe which in turn creates other universes'"
Who? Gravity is a fundamental force. Dark matter may exhibit gravitational properties, if dark matter exists, but that does not mean that gravity is
dark matter. Actually, most of the universe is dark energy. Of course, that could possibly turn into dark matter, seeing that E=mc^2 and E/c^2=m.
Dark matter is probably just the name for the types of substances in the universe that we cannot detect, but know effect the surrounding area. If I
kick you in the dark, you cannot see me, but the effects are known and the leg does exist. That is the premise for dark matter and dark energy.
Blackholes do not create other universes, but they do help to form galaxies and then clean up the mess (vacuum cleaners, if you will).
"all the time pulling matter and light from our known universe to create the big bang in the next one
No. There are many theories as to what blackholes do with the stuff it sucks up. Some think it is spewed out as the dark matter and energy. Others
believe it is given off as radiation according to quantum principles. They may blow up and create a new galaxy for all I know, but I don't think you
can use the term "universe" for what a blackhole does with what it consumes. "Uni" means one. There will always be only one universe per
dimension, even if we use terms like "multiverse." The idea of the universe is the one final picture that sums up all things that happen in our
existence. For some reason, people are trying to claim it means, "the thing that holds galaxies." That is incorrect by the definition of the
universe. Remember that solar systems and galaxies did not exist at one point, but they were all referred to as the universe... now we know better
than to refer to either of them as the universe.
"p.s. there are others that theorize there is no gravity because Earth Sucks choose your theory"
Earth does suck. In more than one way. I think that proves gravity, not vice verse.
I hope this cleared up some misunderstandings.
