I was Having a conversation with my mate the other week, and he came up with the conclusion that if you travel faster then the speed of light, you gain weight, and don't go any faster.
Heres what he said in the convo ( I hope its not to hard to read, I cbb fixen it ;D)
nothing can travel faster than the speed of light right but if you have two particles travelling in opposite directions it is seen that one particle has no velocity and the other obtains all the velocity so if youve got two particles travelling in opposite directions at the speed of light one obtains double the spped of light speed* BUT! nothing can contain double the speed of light so the equation Momentum = 0.5*mass x Velocity^2 has to account for the gained energy Ke = 1/2mv^2 the same equation if momentum is increased exponentially but! velocity cant then energy is increasing but velocity cant SO the mass of something has too so! as something goes faster than the speed of light it stays the same speed but its mass increase increases* so technically if you travel fast enough you gain weight
So I wanted to know if there were any faults in this?
the only way to move at the speed of light would be to find a propellent that moves at the speed of light itself. since the only thing you can propel matter with is other matter, and since matter cant move at the speed of light, it would be very difficult. also, if you do manage to go the speed of light there would be the problem of time warps. since time is relative to your position in space, gravitational force exerted and the velocity at which your moving, you could travel at the speed of light for ten years from your perspective then slow down and find you've been away for ten thousand. this would cause more problems then it's worth unless the purpose of the journey was to go to the future. in my opinion the only practical ways to move great distances would be; worm holes, subspace, or hyperspace. each of which would have it's own advantages and problems.
All I know is that the astronauts that once orbited the Earth actually got an extra hundredth of a millisecond of life after travelling so fast around the planet; the International Space Station could make one orbit of the planet within approximately 90 minutes!
We have 2 trains traveling one toward another (cope with me) at the speed of light. When they hit each other, the energy into the crash would be those of 2 times the speed of light? Why?
I heard about that, th100, they were orbiting around the earth going the opposite way of the spin of the Earth and gained a ration of a second of life.
