  Even though Einstein provided equations and mathematical proofs for the possibility of time travel, grandfather paradox makes more sense! I don't think we can imagine time travel now. All we can think of is its consequences which seem to be dramatic no matter how minor the changes we do when we travel. If we think about it, If I go back 100 years back and changed the place of a stone, this may cause the world today to be in a totally different way! You never know! imagine we went back in time and killed Edison! or Einstein! I don't think we have material things about the past! traveling in time means that the earth is not a memoryless system! it means that every single detail that happened since the beginning is still there! I can't imagine how humans can bring back that memory! Traveling to the future is also controversial! future events did not occur yet! Or else our existence has no meaning! BUT who knows!!! imagine telling someone 200 years ago that there will be a machine through which I can talk to you while you're thousands of kilometers away! He'll say the same stuff we're saying now about time travel 😛
