I just came across this at The Long Now via Noah Brier’s blog and it got me thinking. I’ve often wondered what I would do should I ever find myself traveling back through time. I’m ashamed to say I think I would be ill equiped both to steer humanity in the right direction and to profit personally. I guess this is one less thing I’ll loose sleep over.

And yes, energy does equal mass times the speed of light squared and no, I’ve never heard of this Einstein fellow.
