Science Buddies: "Ask an Expert"

As the title said, - Is there a point where gravity stops affecting due to distance?

Since, the universe has been proven to be expanding at a high rate, but due to the extreme totall mass of all planets should there not be a pull that's slowly but surely are pulling in all the planets to the big bang singularity point? (Where the big bang was created)

Because, unless gravity stops affecting due to distance, should not the universe be slowly decelerating and eventually be colapsing in on itself, ultimately (in gazillionz of years) be one INSANELY BIG planet or something simluar?

Thanks

Now that I think about it, does it not have anything to do with black matter? That's it's invicible energy is pushing the universe out so that it's constantly accelerating or holding the same speed as it expands?

Science makes my brain hurt..

Don't forget to tell me this If you got the answers. Although your hypothesis of Big bang singularity attracting planets towards itself is strange but not unique. There are some theories that suggest, as Universe was made from a single singularity point It will one day will be reverse and go back to be that single point again. Which means all planets and matter , objects will collapse again in that point . Science is *****************. You know what.

Hi Arcten,

Is your question related to a K-12 science project? If so, what is the hypothesis you are trying to test? If not, then a different set of online forums would be a better place for your question.
