Do We Know What Gravity Is?

[Bosco]

My roommate claims we don't know what gravity is, I say he is a dumbass. Which is true?

[sabotai]

I wouldn't be surprised if both were true...

[wig]

We don't know what gravity is.

[Poli]

We are not as strong as we think we are.

[sabotai]

We know what gravity is...it is the force that causes to masses to attract each other (or something like that). Do we know WHY there is gravity or what CAUSES gravity? No (at least, I haven't heard if they found out)

[wig]

The theory of "gravitons" is one of the most rediculous things I've ever read about.

[Bosco]

Has anyone ever hit the cover off a baseball?

[Poli]

All I have to do is look at really big people. Gravity exists.

Can you briefly describe the theory? I've never heard of it but I'm not much of a science enthusiast.

So you're saying you are attracted to really big women???

No, fortunately. I'm saying I'm surprised some ships in the Navy still float with the weight of some sailors out there.

I think somebody needs to change the bong water. Or check out Einstein's Theory of Relativity. Or watch the episode of Sesame Street where they talk about Isaac "Shaft" Newton.

You aren't kidding. A couple of years ago I was working with a guy who came off a carrier. He had to be topping 400 easily. He said he gained it all after he left the Navy but damned, he wasn't that old.

The really basic idea is that gravitons are particles like protons that have no mass, but transmit "gravity" from one object to another.

It kind of like me throwing a ball to you, and then the ball pulling you towards me when it gets there.

So presumably larger objects would have more gravitons thus their greater pull?

larger objects = heavy people

Exactly, larger objects would emit more gravitons.

This brings up the law of conservation of mass. Since an object can't emit mass without getting smaller, they "decided" that gravitons have no mass.

It's all bogus science if you ask me.

Well, not necessarily so as heavy is supposedly a byproduct of gravity not vice versa.

[JeeberD]

I hate physics...

If you throw in a flux capacitor, I'm in.

Maybe they're carried by neutrinos? I still don't understand those but aren't they massless and invisible and made up too?

[Poli]

I thought neutrons had mass.

Since I'm not a science guy you'll have to tell me how many gigawatts we need.

[sabotai]

1.21 Gigawatts!?!?!?

I believe they do but neutrons are not neutrinos which I think were supposedly emitted during the big bang.

It's a common misconception due to the Back to the Future movies that flux capacitors are gigawatt rated.

Neutrinos. Sounds like what I had for lunch.

Quick lesson, neutrinos are a lot like electrons, except they do not carry a charge.

Wouldn't that make them "neutrons"?

[sabotai]

No.

I thought you defined a neutron there. Weird.

neutrino - like an electron, but without an electrical charge. Are not found in atoms (at least, I don't think they are). It is one of the fundamental particles.

neutron - along with protons, neutrons are found in the nucleas of an atom. Are made of quarks (a quark is a fundamental particle)

[Poli]

Eh, I think in terms of pro, neu, and electrons. It's my job, sort of. I try not to think outside the atom.

Gotcha.

[Axxon]

And you wonder why I'm not a science guy.

So sabs, what's the point of neutrinos anyway???

[sabotai]

The point of neutrinos? I think you'd have to ask god or some other all-powerful thing that one.

[Axxon]

Ok, but as I recall they are a theory which we can't verify, right? We can't see them, measure them or anything .

In this case, while their existance is indeed god's domain, the reason we invented the theory is what I'm asking basically.

[wig]

Lots of these theoretical things are purely speculation.

Scientists think "well, this would happen if there was a particle that behaved this way". Then, they go out and try to find one that fits the description.

It's pretty ass-backwards sometimes.

I agree.

I loves me some gravity. I like it on biscuits in the morning. I like it on my mashted potatoes. I love it on my poke chops. I loves me some gravity.

One of my friends chugged the bong water one time... it was pretty gross.

Braggadociousssss?????

[Sublime]

Was Dark Matter found? I thought i read something on it finally being discovered the other day.

[wig]

I was going to say that "dark matter" was proven, but it's misleading.

As far as I know, "dark matter" is just the term for all the stuff we know should be there, but can't find. We're always finding new stuff that was once part of "dark matter".

Me too...gave me gas.

btw, "dark matter" is just a generic term scientists have given to "unseen" matter in the universe. No direct evidence for it, but is indirectly inferred by such phenomena as the motions of astronomical objects, specifically stellar, galactic, and galaxy cluster/supercluster observations. It is also required in order to enable gravity to amplify the small fluctuations in the Cosmic Microwave Background enough to form the large-scale structures that we see in the universe today.

[Franklinnoble]

I found some dark matter between my toes this morning...

500 years from now, people in grade school will read about science during our time and laugh. They called it "dark matter" and thought there was only one universe? How ridiculous.

[SFL Cat]

^^^^ Especially after we discover there really is a God.

I think the Big Bang will be the one they look back and laugh at us most about in the "world is flat" sense. "They thought the universe was formed from some explosion of illogical matter during which many physics laws don't apply. How quaint and archaic."
