E67 - Time Travel – is it possible?
As some of you know, my background is in physics and astronomy. (Don’t tell me your ‘star sign’ as a smack in the mouth often hurts...!!!)
I apply my physics training to lasers and IPLs and stuff, but I don’t really use my astronomy education much, these days. I like to ‘keep up’ by reading New Scientist and various online blogs and science sites.
But something I see regularly is the topic of time travel. This is something which fascinates most people, for one reason or another. Many people would like to go back in time and change something. Some want to go into the future and see how things pan out.
So, the question is, is time travel really a possibility? Well, here’s my tuppence worth.
My answer is no. And yes!
No, in that travelling backwards or forwards in time to some point in the past or future, is not possible, in the way most people imagine. That is simply because most people don’t understand how the concept of ‘spacetime’ works.
