Historical Ideas on the Universe

Some howlers in there, I'm afraid! - Einstein didn't predict black holes, they were hypothesised far earlier in 1783 by Henry Cavendish. And it was Karl Schwartzchild who used Einstein's own equations to describe the event horizon of a black hole. - Einstein didn't say anything about a rocket "travelling at the speed of light", since special relativity had shown it was impossible for anything with mass to travel at the speed of light. (Close to the speed of light you would see the mass increase, but exponentially so that it would have infinite mass at light speed.)

Thank you so much! I would not have got this done in the sort amount of time I have available.

Excellent resource. Thanks for saving me the time of preparation

Excellent powerpoint. will be enjoyed by many students. Thanks for sharing.
