It would probably have to be a massless object, since anything with mass cannot go faster than light according to Einstein's theory of relativity. There are particles, such as neutrinos, which approach the speed of light but do not quite reach it. Also, there is a proposed particle called a tachyon which is said to travel faster than light. There is one catch. Tachyons could exist only
before the creation of the universe.

No.
You could look up the hypothetical tachyon particles but there's zero evidence at all that they exist.
You say its a huge universe and it hasn't all been discovered yet - That's true but you have to remember that physics is not like zoology where you can look in to a deep forest and find some strange animal - if we understand a law of physics - and many of them we understand extremely well - then they must hold everywhere. Here and at the opposite end of the universe.
Einstein showed that light was a cosmic speed limit with his special theory of relativity. To accelerate an object with mass up to the speed of light would take an infinite amount of energy - and that does not exist.
Black holes may suck in light as you say, but that doesn't mean that the light changes its speed at all. The speed of light is variable - but not in the normal vacuum of space, we have slowed it down to a few metres a second in exotic substances called 'bose-einstein condensates' which are a different form of matter from solids, liquids, gases or plasma.
So no, nothing can go faster directly. Though there may be ways around it. You mention wormholes - well if you enter a wormhole and come out another one a million miles away one second later, then you've basically travelled faster than light, right?
Remember huge universe - but one set of physical laws that runs the show.

You say that the universe is very big, and therefore there is likely to be something that is faster than the speed of light, although this goes against Einstein's basis for relativity. It is very very very unlikely that there is, as it is theoretically impossible.
I do like the stance you take on the black hole theory though, and unfortunately balck holes are the biggest problem for physicists. They are the only existing exception to Einstein's theory. I think the answer lies elsewhere though, as looking at current particle accelerators we can can get sooooooo close to the speed of light. Surely, with technically advancements it is possible to supercede this? Who knows where Einstein's theories will lie in 50 years time.

You have an ill conceived visualization of Black Holes. Black Holes are not like super vacuum cleaners sucking in everything around them. Black Holes are super massive gravity potential wells that warp the fabric of space time. So instead of visualizing a hole on a golf course with a huge vacuum machine attached, visualize instead that the putting green is in a valley and the green itself is deep cone shape with the hole itself at the bottom. Outside the green (the event horizon) light travels along a curved or warped piece of the fabric of space/time. Here light can even be turned around and sent back to its source. Once inside the green, however, the curvature in the fabric of space/time will not allow anything to escape

No. The physics involved require that it would take an astronomical amount of fuel just to accelerate an object up to 50% of the speed of light.
The faster you speed an object, the higher that object's mass becomes--meaninging it takes still more power to accelerate it even a teensy bit more.

Black holes don't suck light. It's just that they're so dense that the speed that would be required to escape from their surface is greater than the speed of light. Mathematics tells us that nothing can be faster than the speed of light, and mathematics can't lie.

No, because of relativity, as you approach the speed of light, your mass increases to infinity, and you cannot accelerate an infinite mass with a finite amount of energy...

The reason black holes can 'swallow' light is because of their immense mass, not even light can escape it's gravity.
Nothing can travel faster then the speed of light.

Due to recent discoveries, the speed of light may no longer be constant.
Mathematics may not lie, but they may be wrong ... and in this case, it does seem possible that faster-than-light travel may be possible -- it would require vast levels of technology we are far from achieving, however.
