The Kamehameha Wave



Extra credit: Knowing a Kamehameha wave travels at half the speed of light, and that 1 light-minute equals 1/10 of an AU, how long would it take for the blast to reach the sun?
Goku can fly, so the time depends on how far he is from the sun. Also, he protects the Earth, so he'd never destroy the sun.

Astronomy


My astronomy is a little rusty, but I think that should read Evolution OF the Main Sequence. Oh and that's a nice drawing too.

Supernova


A star in the sky suddenly brightens to many times its original brightness and then fades gradually over the next several years. Hypothesize what happened in terms of a star's life cycle.


It just had a hot flash and is probably going through menopause.
