I think it's true. Thats why you can't see stars near black holes.

Yay, 2 trues,  eintein is smarter than all of us....

Oh man, don't even get me started with that stuff already. I'm only 10. 

this is the E=MC^2 thing, right?
it makes some sense, although there are more forms of energy than just motion.
Energy=Mass*Speed^2
makes sense, although it should be made clear that it's kinetic energy.

I have a theory that when matter goes past the speed of light, it goes so fast that light cannot keep up with it; therefore the retinas in human eyes cannot pick up the light bouncing off the object, so the matter going faster than light becomes invisible.

Also, however, there is the idea that when gets the the speed of light, it isn't matter anymore. At that point it is said the matter is shifted into energy, which might seriously screw the matter up when it stops going at light speed.

Of course, depending on the idea above light speed may or may not be possible.

This is some of what I know on the topic 

Are you saying that you think matter can go past the speed of light; we just can't see it? I sort of doubt that theory, to be honest. We can still hear things that travel past the speed of sound.

another thing that is somewhat relevant to the topic:

You all know the universe is expanding. The universe is constantly doubling is size. Since time is just a measurement of how long it takes light to go unhindered through a certain area.

If this is true, what if the universe is expanding at a rate faster than light can travel? since the universe is expanding faster than light can travel, light never reaches anywhere and time ceases to exist.


when I first learned about this, I was like

WHAT.

Well, I've heard that strong gravity bends space and time (    ) but I'm not sure about the theory itself.

Well your under the asumtion that the univers wont colasp or shrink or rip, light would never get to us, but if you belave the universe will stop rip or collapse then we will get to see the light

You get it then

Correc

Great topic. Thank you for making such a topic. Can I help you in your project ??

If you were near a black hole, you will be sucked in and if a star is near the black hole, the star will be sucked in. So either way, the point is poor.

Einstien said that NOTHING can go past the speed of light.
Even if anything did go faster than light, it wont be invisible because you still can see its back (when you are behind it). It is not that you CANNOT see it but you might see it after it has passed (depending upon how fast the matter is and in which direction it is).

Another question - Light is slower in water. So can an object in water be fater than light itself is in water ????

Quite a very possible option. Good thinking, BTW. 
However, another equally possible option is that some things may exist that are faster than light, but we are unable to sense them. Or that they might exist in more dimensions.

No. What happens is that the mass itself gets converted into energy.So its not kinetic energy

Are you saying that you think matter can go past the speed of light; we just can't see it? I sort of doubt that theory, to be honest. We can still hear things that travel past the speed of sound.

Another point to be taken into consideration that sound is caused by contraction and expansion of the medium itself while light is a Wave. So, we might be able to increase the speed of sound of an object but we cannot increse the speed of light coming from that object.

Good hypothesis but it is slightly incorrect. Even if the universe expands faster than light can travel, this expansion is not at a particular place. It is actually divided between millions of light years. So only that when you should be seeing the object after 1 seconds, you will be seeeing it after 1.2 seconds
