An Astronomy Professor's Take on Superman's Powers

Mr. Brashier,

I assume this was sent in jest.

I hope you don't get your "facts" from comic books, movies and TV shows.

Regards,

Prof.Geller

Dr. Geller,

During your lecture on the Sun we discussed how the temperature of the Sun dictates that it will emit roughly equal amounts of all wavelengths of light which makes it appear yellow/white.

Thus if the sun cooled down by approximately 1000K it would have a more reddish appearance.


Given the fact that Superman gets his power from the light of our yellow sun and conversely his home planet of Krypton had a red sun which drains his strength, can you please explain what characteristics of fusion within a star would produce super-human strength giving light at 5500K but not at 4000k?


The difference in temperature between a yellow star and a red star appears to correspond to a 100nm change in wavelength. Therefore it would appear that Supermans strength and bulletproofness are functions of a very narrow slice of the visible light spectrum.

On this issue science seems to directly contradict the facts presented in the comic books, movies, and TV shows.


Thanks,

Mike
