Could 501 seagulls really airlift a peach that large? The answer: No. To make it work, James would have needed approximately 2,425,907 seagulls.

After winning the 1965 Nobel Prize in Physics, Richard Feynman received a letter from Dr. George Beadle at the University of Chicago offering him an honorary degree.
This was his reply:
Yours is the first honorary degree that I have been offered, and I thank you for considering me for such an honor.
However, I remember the work I did to get a real degree at Princeton and the guys on the same platform receiving honorary degrees without work—and felt an “honorary degree” was a debasement of the idea of a “degree which confirms certain work has been accomplished.” It is like giving an “honorary electricians license.” I swore then that if by chance I was ever offered one I would not accept it.
Now at last (twenty-five years later) you have given me a chance to carry out my vow.
So thank you, but I do not wish to accept the honorary degree you offered.
Richard P. Feynman

All the evidence now points to the likelihood that our Universe will keep on expanding forever, at an accelerating rate. The process is exactly like a slower version of the inflation that produced the bubble of space we live in. Eventually — and it doesn’t matter how long it takes since we have eternity to play with — all the stars will die and all the matter of the Universe will either decay into radiation or be swallowed up in black holes. But even black holes do not last forever. Thanks to quantum processes, energy leaks away from black holes in the form of radiation. This happens at an accelerating rate, and eventually they disappear in a puff of gamma rays. So the ultimate fate of our Universe is to become an exponentially expanding region of space filled with a low density of radiation. This is exactly the situation described by the solution to Einstein’s equations found by de Sitter, and known as de Sitter space.
