If universe is expanding but mass of sun and planets is not then shouldn't gravity be reduced due to space-time and mass relation?

The answer is that the expansion of the universe is only noticeable over distances of hundreds of millions of light years or more. Over the much smaller distances found within galaxies and planetary systems its effects are negligible.

∙ 14y agoYes. If, The Universe is expanding. E = -GmM/r is gravitational energy, matter and energy are part of the Universe , are they "expanding"?
If , it Is only the empty space that is "expanding"? How can that be the meaning of an Expanding Universe? Further, Is space empty? If space is not empty then expanding space means creating new matter as the Universe expands. Something form nothing.
The answer is the Universe is not Expanding.

Is expanding universe accurate?
All the available evidence strongly indicates that the Universe is, indeed, expanding.
What is the big impact theory about?
Big Impact Theory is an alternative theory to Big Bang Theory. The Big Bang Theory relies on a primodial sigularity or white hole to pour out all the energies that would transform to become all sorts of matters and anti matters , convertible energies and dark energies, and the associated spaces (which jointly evolve into spacetime universe). But the origin of that singularity point cannot be explained. The Big Impact Theory however alleges that the spacetime universe orginated from the remnants of 2 spiritual universes (each of opposite polarity) which bumped (hence the name Big Impact) at the wrong point and in wrong tempo (hence did not vanish ). Time is a transformed anti-spatial co-ordinate vector, and all particles are from time spirts and spatial spirits bound by pristine energies. It alleges that the anti-universe exists as a negative pristine energy shell (trapping some spatial spirits) with immense diameter , and it encircles the relatively small spacetime universe which is expanding radially. This explains why the spacetime universe is ever expanding. More can be found about this by searching for the blog titled "Why you need to understand universe before you can understand yourself" David King
If there was no universe or plants where did the big bang happen?
It happened in the center of the universe, for which it is still expanding on the universe.
The implication of hubbles law is that the universe is?
That it is expanding.
How is the universe expanding even if atom can't be created?
It is space that is expanding. The amount of matter doesn't necessarily increase. This means that the average density of the Universe is decreasing.It is space that is expanding.

If spacetime is expanding into infinity then are blackholes going to be ripped apart or will they possibly save the universe from its entropic end?
These questions cannot be answered at our present understanding of physics. Check with me in a few centuries; we may know something by then.
Why is the universe cooler?
It is because the Universe is expanding.
When was ...And the Ever Expanding Universe created?
...And the Ever Expanding Universe was created on 2009-07-14.

What are 3 possible outcomes of the universe?
1. the universe continues to keep expanding 2. the universe slowly stops expanding 3. big crunch (basically the universe will stop expanding and fall back into itself)
Acknowledge limit of the universe?
The consideration for whether our universe truelyhas limitationsdepends on one's determination of what the universe means to them. It could be said that the universe is endless because its very determination is built upon the evolving consideration of a reality within the dimensional degrees of SpaceTime convergence. It might be stated that our perspective of universal reality is bounded by our fourth dimensional frame of reference for existence within this SpaceTime continuum. In this sense of existence, it might be stated that our universe is not infinite; for outside this fourth dimensional abstraction of the SpaceTime continuum, our reality of existence has no meaning. Yet within the consideration of our traditional fourth dimensional existence, scientists agree that the Theories of Relativity and Special Relativity bound our universal reality with a definable SpaceTime continumm. By virtue of these theories, expectations are extrapolated. One such expectation is that once the universe was once created by the Big Bang, the universe will end in a Big Crunch. Another expectation is that once the universe was once created by the Big Bang, the universe will end in a Big Rip. Therefore, by virtue of these theories, our universe within this fourth dimensional abstraction, will eventually evolve beyond its current dimensional limitations. And, as stated before, outside this fourth dimensional abstraction for our SpaceTime continuum, our reality of existence has no meaning Other: Universe is endless and it is expanding all the time ,it is expanding and getting bigger with the passage of every second.ithis expansion of universe is due to the result of the big bang (big bang theory)--------------by Sanatan
If scientists say the universe is everything and the universe is always expanding then what is the universe expanding into?
It is not exactly expanding into anything. The galaxies are moving apart from each other, from which we can infer that the universe is expanding. Theoretically, this is a result of the Big Bang, in which the universe began when all matter was compacted into a very tiny sum, and then exploded apart in a very big bang, and as a result is still expanding today.
When the universe is expanding?
the universe is expanding continuously even right now as you read this little sentence I wrote.
Can anybody suggest a good book on spacetime topology?
How the Universe Got its Spots.
Why was there a big bang to start the universe?
There is no 'why' for"Why was there aBig Bang to start the universe." The Big Bang is just one of many theories and beliefs that our universe had a beginning in SpaceTime. It is justa conceptual abstraction of SpaceTime via people that all existence evolved from some prior causation.
Do volume in the universe change?
Yes. The Universe is expanding.
What does the redshift tell us about the universe?
that the universe is expanding.
