Gravitons seems a complex solution, compared to curved space. Consider two galaxies in a local cluster if each particle with mass is interacting with every other via gravitons? As gravity is rangeless, does that imply that every particle with mass in the universe is in a graviton exchange...

Sorry Simon, I'm not framing the question coherently. Am I right in thinking that in a simple 1 star 1 planet model, the GR solution gives space as curved and the planet's orbit is the natural or straight path thru it. The QM solution uses gravitons as a messenger particle to tell the planet how...

How frequently do two particles with mass exchange gravitons, or if they are "broadcast" how frequently does a particle with mass emit gravitons?

I have some basic questions about gravitons. If you have two particles with mass, do they "exchange" gravitons, if so what is the frequency?

So in an open universe scenario, todays observable universe was 13.4 million years ago smaller than a proton, plank length=1.616199 × 10-35 metres (diameter, radius or whatever!). However the universe was infinite in the 3 spatial dimensions, using our mini plank universe as an arbitary origin...

Going back to the original question in this forum, where the TV program stated "He further went on to say that after a trillionith (spelling?) of a second, our universe was the size of an orange and ... ". So we are talking about the size of the early universe, very shortly after the big...

I think its misleading and in the past has misled me. If I was to say my shoe size is about that of a watermelon you'd think I was crazy or at least had the oddest shaped feet in the universe. Using diameter and radius implies spherical, has does analogies with speherical objects. I never seen...

Do you think the commonly used phrases like 'size of an orange' or 'size of a grapefruit' to describe the size of the universe causes the concept issues with shape and centre. While cosmologists and TV programs use these terms along with words like diameter and radius, lay people will...

So DM contributes to the gravition force, but is not responsive to gravity? The Wiki suggests it clusters in a large ball around galaxies, what if not gravity causes it behave this way? Or is it that as it falls toward the centre of a body, the accelertion caused by gravity is enough to give...

If DM is immune to the electromagnetic force but not to gravity and the universe is homogenius, would we expect the find DM at the centre of normal matter bodies such as stars and planets trying to form black holes?
