/sci/ - Science & Math

haaaaaiiii guys ^^

ok, so I want to know:
WHAT MAKES LIGHT SO DARN FAST??

I mean, I can imagine it being fast from a super nova explosion, but a lightbulb isn't even moving.
It just gets hot, then suddenly WHIZ tons of photons come blasting out at LIGHT SPEED.
that's FAST.
Why is it so fast? I know light has almost no mass, so it's not momentum, right? Why doesn't light stop when it hits something? Why is it turned to heat?
And if it's a mirror, why does it continue to go just as fast after it hits?
And of course, does light have acceleration?
Like when the lightbulb filament sends out that first speck of light, is it going light speed, or below that?

Thaaaaaank you >^,^<
this is the third time posting this, please be in the right place -,-;;

Comp sci major here; I got a C in Calc II, but understood everything perfectly. I failed the first couple months badly because I was too busy with work/family problems and was able to bring my almost complete absence of grades up to a C.

Is that C going to come back to bite me in the ass later on, /sci/, if I apply for graduate-level studies?

maybe you should stop it then. you're obviously just compensating cos you're not manly enough....

The electron discharge motors are not providing enough jiggawatts.

>Why do random mutations occur?
When the genetic code is being copied in reproduction there is a small chance that is will 'misread' itself, ergo make a change to the original design.This mutations is usually detrimental for the creatures survival, but sometimes, by chance, the error will result in a better design than the first. Allowing the creature to have a better chance of survival and a high chance of spreading its altered design to the next generation.

Carl Sagan's Cosmos Episode Two explains further on this.

>I was wondering how evolution might affect certain habits like alcohol consumption
I don't know whether addictive behaviors are genetic so cannot comment of if this is relevant to evolution.
