Journal Lendrick's Journal: Scientific American on time travel
I don't have a whole lot of time to write today, but I saw this and thought it was pretty cool. The really strange thing is the idea that time is basically one unchangeable unit... Even if you're able to build a time machine, you can't change the past because you already did. I suppose that doesn't make a whole lot of sense, but read the article. Cool stuff.
