I'm no genius, but I'm certain the speed of light is not the fastest. There are many that we do not know about the Universe, and even if we do, there are many different things to understand. Our math, science, and physics equations are limited to our knowing, but what about other life forms out there? What are their understanding of math, science, and physics? Maybe our education is the lowest compared to them? I think we can go beyond these things we say that has a limit. Just think... a black hole traps light. You have to travel faster than light to escape from a black hole.

For the first time, astronomers have managed to measure the rate of spin of a supermassive black hole—and it's been clocked at 84 percent of the speed of light, or the maximum allowed by the law of physics.
"The most exciting part of this finding is the ability to test the theory of general relativity in such an extreme regime, where the gravitational field is huge, and the properties of space-time around it are completely different from the standard Newtonian case," said lead author Guido Risaliti, of the Harvard-Smithsonian Center for Astrophysics (CfA) and INAF-Arcetri Observatory in Italy. (Related: "Speedy Star Found Near Black Hole May Test Einstein Theory.")
They can pack the gravitational punch of many million or even billions of suns—distorting space-time in the region around them, not even letting light escape their clutches.
The predatory monster that lurks at the core of the relatively nearby spiral galaxy NGC 1365 is estimated to weigh in at about two million times the mass of the sun, and stretches some 2 million miles (3.2 million kilometers) across—more than eight times the distance between Earth and the moon, Risaliti said. (Also see "Black Hole Blast Biggest Ever Recorded.")
Risaliti and colleagues' unprecedented discovery was made possible thanks to the combined observations from NASA's high-energy x-ray detectors on its Nuclear Spectroscopic Telescope Array (NuSTAR) probe and the European Space Agency's low-energy, x-ray-detecting XMM-Newton space observatory.
Astronomers detected x-ray particle remnants of stars circling in a pancake-shaped accretion disk surrounding the black hole, and used this data to help determine its rate of spin.
By getting a fix on this spin speed, astronomers now hope to better understand what happens inside giant black holes as they gravitationally warp space-time around themselves.
Even more intriguing to the research team is that this discovery will shed clues to black hole's past, and the evolution of its surrounding galaxy.
Tracking the Universe's Evolution
Supermassive black holes have a large impact in the evolution of their host galaxy, where a self-regulating process occurs between the two structures.
"When more stars are formed, they throw gas into the black hole, increasing its mass, but the radiation produced by this accretion warms up the gas in the galaxy, preventing more star formation," said Risaliti.
"So the two events—black hole accretion and formation of new stars—interact with each other."
Knowing how fast black holes spin may also help shed light how the entire universe evolved. (Learn more about the origin of the universe.)
"With a knowledge of the average spin of galaxies at different ages of the universe," Risaliti said, "we could track their evolution much more precisely than we can do today."
It's difficult to comprehend gravity so extreme that it even sucks light to itself. How can we ever study these black holes when we can't get any of our technology near them?
I've always wondered, what is after a black hole? Is there another universe or just.. BLACK?? I wish someday, if I have chance to study in Harvard, I'll find the answer. And Andrew Turton: Going back in time has been tried before. But to go back, every ''thing''s cells, organisms has to tear apart and for example 1 second later, it has to come back together, which is something impossible, as I know they are working on it.
@Alex Thorne You should study or read about Stephen Hawkings theories about what lies on the other side of black holes. Some theories even state that perhaps each blackhole is the location of a "budding" universe growing off of our own, filling that new universe with matter and energy that is absorbed and transferred through the event horizon and beyond.
@Alex Thorne Gonorrhea.
i think objets can move faster than the speed of light, and if so there could be a way of traveling back in time or if not to travel back in time then to look back in tme, i have no education but a head that will not leave me alone, i even think i may know how to build a chariot like gods using todays technology in if it is so it could have been built years ago, trapped in the uk ME
@Andrew Turton @Alex Thorne With the current model, it is not possible for any particle (with the exception of photons, since they are massless) to reach the speed of light. Essentially, as an object approaches the speed of light, any forces acting on them effectively approach zero, so the particle cannot be pushed to or past the speed of light. Also Alex, not sure what you mean by what's "past" a black hole, a black hole isn't an actual hole, it's simply extremely dense mass formed by a collapsing star.
@Nicholas Glennon @Andrew Turton @Alex ThorneBlack holes ARE NOT super massive objects with huge density. This is a common misconception. There's no matter in a black hole anymore, it has become energy and this energy has been used to distort space and time. This is what happens according to the equations of general relativity. Inside the black hole the known laws of physics don't work anymore.
Gravity distorts space-time. Mass and distance are what affect/create gravity. Black holes are tremendous amounts of mass compacted by the force of their own gravity into a relatively tiny volume. Incidentally, if they were pure energy, they would have relatively negligible mass, therefore negligible gravity.
Astonishing that the 1200 cc (avg) space within a human cranium can apprehend something so vastly beyond itself on every scale imaginable. What are we, really?
"By getting a fix on this spin speed, astronomers now hope to better understand what happens inside giant black holes as they gravitationally warp space-time around themselves." Not unlike this, it seemed Einstein had the measurements to prove relativity early on. He predicted light would bend around the sun, famously measured by Author Eddington during a solar eclipse, all based on his space-time curvature. Eddington’s explanation was that space-time is warped by gravity, according to Einstein’s general theory of relativity. However this explanation is based on a misconception spawned by flawed self-contradicting non-Euclidean geometry in the theory.

yes i think if you go one way long enough you will end up back where you started in space and they will see i am right soon as they can look far enough and see the back of us ---i beleive this is right but i need to do some more work on it yet
well woopy due and just how far are we able to see out into space so far and could it be or is it posible that somewhere out there is the end of space like back when the found out there was an end to the ocean i mean if you go one way in space far enough do you get back where you started if that is true then it would be a 8th demention of some kind--so figure it out ok we will be waiting for your answer
These six scientists were snubbed for awards or robbed of credit for discoveries … because they were women.
Scientists say they've learned why penguin wings, now used for swimming, no longer get the birds off the ground.
