Oh, sorry, is that one too hard? I cant remember when I learned that about quarks and protons. Well, I'll leave it up for a bit until someone gets it. If you're too lazy to go back one page and look ;) , here's the question on the board:

How many quarks are inside of a proton? (And BIG bonus points if you can say what they are called and what their electromagnetic charge is :) )

I haven't studied quarks yet (or very many other leptons either, for that matter, except for electrons) so I don't really know much about this... :eek:

And me the originator of the thread, too. Shocking! :D
 
good Dernhelm! that's exactly right. Now for extra credit, do you know what the charge is of each? (Hint: the total charge must add up to +1). :)

Olorin, it's cool! You're not as old as us (especially me!) And I've looked through some of your answers and I'm pretty impressed with you much you do know :)

Okay, here's another one:

Which star in a very renowned constellation is referred to as the "armpit star"? (No joke!)
 
Must be Betelgeuse... only constellation that I can think of that even HAS an armpit (except for Hercules, but that's not really a renowned constellation, is it now?).

Q: What causes sunspots?
 
Yes, Betelgeuse!...as far as the sunspots go, the last i checked, we dont really know why. have you heard something else?
 
hmmm, oh okay. Yeah, I'm pretty sure it has something to do with that, but the phenomena of sunspots is not completely understood yet.

Okay, next question:

What is at the center of our Milky Way Galaxy?

I do know they have partial charges, but I have no idea what they are. I'll give you my best guess. ;)

3/4 and 3/4 for the two up-quarks, and
-1/2 for the down quark? :eek:

Q: Which galaxy is closest to ours?

Is it Andromia? (sp?)
 
HAHA!! Caught you! That was a trick question...

Technically, the galaxies closest to ours are the Magellanic Clouds. However, since they are satellite galaxies, I suppose you call Andromeda the closest galaxy.

Q: What is an electromagnetic wave comprised of.
 
An elecric field produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field, which produces an elecric field which produces a magnetic field...which leaves me wondering if the light wave was the first Duffer. :eek:

How long does it take to fall into a black hole, from the perspective of a person watching?
 
First off, an electromagnetic field's messenger particles are called electrons. You might remember that they have negative charges, especially right before the sheriff's bid for re-election.

As for falling into a black hole, a body spirals inward, and their forward velocity and angle of approach will determine the shape of the spiral. In most cases that works out to two shakes of a lamb's tail...one to yell "HELP!" and one to realize that nobody hears you in outer space.

3/4 and 3/4 for the two up-quarks, and
-1/2 for the down quark? :eek:

Good guess! It's actually +2/3 for the up quark and -1/3 for the down quark though :)

To answer the current question about how long it takes to fall into a black hole: it would take an infinite amount of time from the perspective of the person watching according to our current best theories of gravity.

And to comment on the EM field, it is correct that the electromagnetic force only acts on charged particles, but the force carrier of the Electromagnetic interaction (according to quantum electrodynamics) is the photon. (We say that the photon mediates electromagnetic interactions between charged particles).

New question, a little less exotic: (in a sentence or two... ) Why does it take longer to cook something in the mountains than at sea level?

I like EveningStar's answer better.

*runs out before they try to make her answer the current question*
 
C_T: Because the air in the mountains is thinner, thus resulting in less air, which means less oxygen to complete chemical reactions with.

Q: What is the fundamental difference between a crustaecean's circulatory system and a mammal's?
