A Little Time Travel Thought Experiment

During the Back to the Future (BTTF) anniversary celebrations there was a lot of talk about how accurately they represented time travel. The consensus seemed to be that travelling back and appearing at the same physical location but in a different time was how time travel would likely work. This is where I got thinking. The universe is an ever moving beast. Nothing sits still and this leads to some pretty big problems. To start with the Earth rotates on its axis every ~24 hours, so our traveller would need to arrive at approximately the same time of day in the past. He’s worked out time travel so that’s not going to be hard to do. Next, the Earth orbits the sun every ~365.25 days. This one is a little more of a problem. If our traveller is in the heat of June and has decided to travel back because he wants to see an Xmas in the past he’s got a problem. The Earth will be on the other side of the Sun. So Marty needs to travel back to roughly the same day each year? Fair enough I suppos…

Is It Really Nearly Two Years?

It doesn’t feel like almost two years since I last posted on 22hundred.net. I have written a few posts for mikemcconville.com over on the Medium network but it hasn’t felt quite the same. It’s time to come back home.

Coming back got me thinking and re-reading some of my old stuff. While some of posts were quite good, if I do say so myself, some could've done with more time to develop before being published. A few years older and wiser, this time is going to be different. Going forward my goals are to:
•Post regularly (once or twice a week)

•Post quality

•Have fun doing it


To reflect this, the blog is now called 22Hundred Ruminations.

So, lets get going.
