If the whole universe was revolving would that explain the speeding up of it ?
If the universe itself was revolving , would the outward thrust cause the galaxies at the edge and expansion in general to be speeding up, hence the finding which the physicists have put down to dark energy , what they can't detect?
Answers:
A number of good answers so far, but I'll add one other thought --
the increased expansion rate of the universe refers to space, and that's not subject to forces caused by any revolution. The expansion rate has been measured by observing ancient supernovae which are embedded in space.
P.S.
The correct term for the unknown energy that seems to be the cause of the acceleration is DARK ENERGY (..or 'quintessence'), not dark matter.
It is possible, but I don't really know. After all, 'Atoms are the smallest particle of element. It is so small that no scientist has ever seen it and yet they are sure that they exist.' (A quote from a book)
The universe might not even have an end to it. It might just continue to expand till the end of time.
Sorry I thought the expression was dark matter. As I understand it when they measure the gravitational pull of certain stars there is not sufficient matter to account for the force involved so they are assuming there is other matter there which is exerting gravitational force. I don't this it has anything to do with the speed of the stars
I could be wrong maybe someone knows better
I don't believe the universe can ever be considered to be revolving as there is nothing outside the universe to use as a frame of reference.
Revolving with respect to what?
Surely its impossible to determine if the universe is revolving.
centrifical force of a spinning object pulls it farther and farther out from the center.
when u talk abt revolution.u mean a certain axis rite....
but the whole universe cant be considered as revolving
speedin and expansion of universe is a different concept....
Dark energy is the remnant of the vacuum that the universe is still in the process of stabilizing.
yeah, it could be. But then you'd have to conclude that Earth just happens to be exactly in the center of the Universe.. which is kinda unlikely
sounds pretty spot on to me.if you think that this is a finite universe with an edge.i prefer the infinite universe where 'everything that isn't impossible is compulsory'..maybe even an infinite number of finite universes
i dont know if its revolving or not, but surely friction would cause it to slow down rather than speed up even taking into consideration the possibility that it is revolving
