if relativity theory is correct, no object can travel forward in time at a speed greater than the speed of light.yet quantum mechanics predicts that the tachyon, a hypothetical subatomic particle travels faster than light.Thus, if relativity theory is correct either quantum mechanics' prediction about tachyon is erroneous or tachyons travel backwards in time. This would lead conclude that tachyons travel back in time.
My question is what statement leads to conclude that tachyons travel backwards in time.
The stimulus says that this is a theory and the answer would probably prove that this theory holds true or that another theory cannot happen.
I am not quite sure what you want but have tried to help, can you clarify your issue?
