Technion Israel Institute of Technology researchers have developed a theoretical model of a time machine that, in the distant future, could possibly enable future generations to travel into the past. An article on this research was published last week in the scientific journal Physical Review.
By tweaking Einstein’s space time and general relativity models these researchers are becoming more confident with the idea of travelling back in time, something that most scientists believe to be improbable because of the paradoxes and other reasons that could happen if one did so. Curving space time, as is the basis for wormholes to travel instantaneously from one point in space to another, is the basis for this research. So instead of going to another space point in your time, you go from your point in time to another point in time.
Several issues with the stability of such a curve of space time that can cause disturbances are at the forefront of the research which the scientists hope one day the world will be able to solve.
Many people believe that if a time machine using such technology were ever possible, then why isn’t there any evidence of people coming back and telling us about it? If the positive benefit of time travel into the past is to undo our own mistakes in this world, why hasn’t it already been done, or would we even feel the effect in our reality?
The arguments on all sides of the subject bring up good points, but if we are to expect any evolution in this technology we should continue the discussion until these theories can be completely thrown away, by doing scientific research to rule it out.
