Thats like very hard to imagine.
I always visualized time dimension with the other spatial dimensions. This makes it feel like time is extrinsic to the other spatial dimensions.
Are sure its like expanding INTO the time dimension.

Theoretically, since graviton is also a wave you can use Energy=hf to find its energy if you already determined its frequency. Unfortunately no one has seen any graviton in action. For now, it's really is a ghost (virtual) boson.

So, how do we even say graviton is a wave or not. It only attracts, but does it carry any kinda information. I dont think so. And is there any kind of energy transferred by a graviton.
Is the rest mass of a graviton also considered to be zero.

Good question Michael. But I've got no idea.
My thought is like this.
We have got Nuclear force. We have Nuclear energy.
We have electomagnetic waves. We again have an energy associated with it. E=hf.
We have Gravitational force. But gravitational energy?
I guess they brought in the graviton concept mainly to combine gravity with EM.
What do you think?

The buzz word or key word is "theoretically" It means your guess is as good as mine.

I think that gravity is not fully realized by science,when they do,they will call it something
else!

The Red shift suggests that space is expanding. But where is it expanding to? Does the Red shift also mean that time is contracting? Thats what we are pondering on..

[swoarg]

energy and force are the both different, you would of thought that gravity had energy to be able to creat force.

[dipayankar]

I strongly believe that gravity creates force...

Yeah, Energy and force are different. And yeah I thought of gravitation energy because force is like the transfer of energy. An interaction due to the transfer of energy. Did you have a different point of view.
