We all know by Einstein's Special Theory of Relativty that when an objects at the speed of light, it could move foward in time quicker than the other people. However, I was wondering. Is time travel possible for going back into the past? Can we rewind time as if any two oppposites in nature exist in life? For example, if there is a yin there is a yang. Opposite electrons attract positive electrons. For every man, there is every woman. So in conclusion is time traveling back into the past possible excluding the grandfather clause and if so, how possiblity can it acheieve with our modern technology? Also, are there researchers researching if time travel can be possible for the near future?
