Theoretical Experement...
Imagine you and a group of people are on a spaceship. You have gradually accelerated and are now traveling at 0.9999999c. Try walking in the direction you are flying. You can't! Walking in the direction of motion would be impossible as it would mean you are moving faster than the speed of light!

Just imagine trying to move forward and not being able to. Wow, that would be weird! Your thoughts?

Since velocity isn't additive, it doesn't work that way. 0.9999999999c + 0.0000000001c != c

If I were a passenger I'd simply walk forward, being too stupid
to know I'm not supposed to be able to do it.

Has anyone heard of any theories that suggest wormholes develop around objects approaching the speed of light, constructs that allow space-time conditions of relativity to remain upheld?

The point being made is that some consider black holes to be associated to wormholes. Black holes, I am suggesting, are related to incredible mass, just as travelling at the speed of light would be, namely a sizeable increase in mass. Could near light speed travel "induce" a moving black hole, producing a wormhole effect?

Does anyone know of any actual mathematical theories that point to such a possibility?

I suspect that walking in the direction of motion would be difficult - because of all that extra mass you're carrying around, but not impossible. As Magimaster points out, the whole point of relativity is that you cannot simply add two velocities - you have to take into account the whole 1 - (v^2/c^2) issue that ensures (theoretically at least) that no massive body ever reaches the speed of light - the energy supplied to it increasingly gets converted into extra mass, reducing acceleration and causing only infinitesimally incremental increases in velocity.

Any thoughts on my question?

Do you know of any theories that can link a few of these unanswered questions?

'Fraid not. Your questions are way beyond any competence I might have to answer them - though I'll admite the concept sounds intriguing. I was merely making points based upon my dimly-remembered high school physics - very basic stuff regarding relativity.

Let me know when you do. A few theories exist, but then again, we're talking about what contemporary physics finds a little unbelieveable.
