Response to Time travel....

Tim said: Does traveling beyond the speed of light make time go backwards?

It may not be possible to travel faster than the speed of light. According to Einstein's theories of relativity, it would take infinite energy to reach the speed of light. If this is true, then going faster than the speed of light is impossible.

However, there may be shortcuts around the speed of light. Wormholes, etc...

Tim said: Scenario #1
If a star 3 light years away burnt out 2 years ago, and you could be sent there in the moment, beyond the speed of light, would that star still be the bright shining star it appears to be from earth?

No, the star would be dead. However, on Earth, the light would still be in transit, so you wouldn't know the star had died yet.

Tim said: Scenario #2
You shoot a Lazar from earth to the sun and it took 8 minutes for the Lazar beams to reach the sun.
If you could be at the sun in 3 minutes would you see the Lazar beam?....

No, because the laser light had not yet made it to the Sun.

Tim said: And if you went back to earth in 3 minutes would time reverse or would the Lazar hit the sun in 2 minutes?....

The laser light would still be transiting, and would reach the sun in 2 more minutes.

Time is RELATIVE, depending on where you happen to be, and how fast you happen to be going.

Tim said: Wormholes/black hole? = Gravitation forces so great we don't understand.

Sure we understand them. At least about Black Holes. We understand black holes mathematically just fine. And black holes were predicted many decades before the first one was discovered.

Tim said: Have you ever seen a wormhole/black hole? Show me proof, not evidence.

Absolute proof only exists in logic and mathematics. No one has ever seen a black hole because no light can escape from it. But you can see the effects the black hole is having on the space/time continuum around the black hole.

Have you ever seen a gravitational field? Do you deny gravity?

Tim said: Have you ever seen a creature mutate shapes and scenarios?

Yep. They're called butterflies.
