So, a recent article, written in a respectable scientific medium, argues that Time-travel (or at least Time-reversal) is impossible. I have written on this before, and even tried to offer a layman's version of just why Time-reversal ought to be impossible, or at the very least, will lead to the total destruction of the time traveller. Basically, if you reverse the Time-stream, you also reverse the laws of nature, such as the law of gravity. Everything would explode.
