The Graviton

[Dryson]

http://en.wikipedia.org/wiki/Graviton

After reading through the Graviton Wiki - I was wondering if such an elementary particle would have existed prior to the Big Bang of the Universe where based on what we know about our Universe after the Big Bang occurred prior to the Big Bang such particles with mass would not have existed, could the Graviton have actually existed?

How can one explain the Universe prior to existence using science and physics that pertains to a Universe that came afterwards?

This is a better basic article about the possible existence of gravitons

Well-written and concise! Thank you, Jedi_Master

Though, I do think "Captain Obvious and the Exoctic Gravitons" would be an excellent name for that Carl Sagan tribute band!

Very interesting article Jedi Master

Gravity is the one known fundamental force that has resisted study in the quantum realm and finding gravitons of any kind would be a huge step forward in our understanding of the phenomenon. Devising a successful theory of quantum gravity is one of the hottest goals of modern physics and ongoing experimental searches for gravitons will play a central role.

If we assume that in the quantum realm that existed prior to the Big Bang and the current state of the Universe; planets, suns, black holes, etc., that gravity being produced from another source would have existed because the objects within our Universe had not existed yet to create gravity.

Such gravity would have held systems together much the same way that gravity holds our Universe together.

Maybe the only way to find out is too send a probe off into the darkness of what is on the outside of our Universe.

Unless nothing is outside of our Universe.

 

[HIjol]

In which case, it wil be our big chance to get away from it all...

~REALLY get away from it ALL!!!

Even if there was an edge to our universe, it would take practically forever for a probe to even reach it.

 

[sojourner]

There is no "edge" to the universe.

 

[Jedi_Master]

But there is a restaurant at the end of the universe.

 

[Dryson]

There is no "edge" to the universe.

I didn't say that there was an edge to the Universe. I said that there was an outside to our Universe. An outside of our Universe would relate to the space that we haven't mapped thus far. Once such space has been mapped it would become part of our Universe.

An edge would mean where we have been able to determine the farthest point of measurement to. Universe means a collection of stars, planets, and other cosmic anomalies contained within a region of space where two different universes would be separated by an area of space.
Our Universe would have an edge but space never would.

Would a Graviton be considered a wavelength or particle?

Are you mixing up the terms galaxy and universe?

Sure seems like it.

much the same way that gravity holds our Universe together.

Gravity does not currently appear to be holding our universe together.

A galaxy is a collection of stars(suns), planets, and other cosmic anomalies that are centered around a central gravitational body. Solar systems are just smaller galaxies within each galaxy.

A universe is a large galaxy where all of the galaxies reside within the universe.

 

[RoJoHen]

No.

Gravity does hold our universe together the same way that gravity holds together our solar system.

The celestial bodies in a solar system if not bound by gravity would expand away from the sun just like the universe is expanding away from the central source of the Big Bang.

This would tell me that gravity is most certainty holding the universe together because other wise our solar system would have spread out across the galaxy like pool balls after being broken. Galaxies would have broken up long ago as well.

The universe is expanding, and as it does, stuff is flying farther and farther apart. Just because it's not happening on your time table doesn't mean it isn't happening.

At least I see you understand that our universe is expanding.

So how is gravity holding the universe together if the expansion rate is increasing?

For fuck's Dryson, read some text books and stop typing stupid shit in this forum.

Yeah, Dryson, you're contradicting your own point. If the universe is being held together by the same gravitational forces that hold galaxies and solar systems together, then why is the universe expanding the way it is?
