Will the universe continue to expand? Or it will eventually contract because of the gravity?
Answers
Explanation:
If the gravity within the universe is strong enough, it could reign in the expansion and cause the universe to contract. If not, the universe will continue to expand forever. Based on the matter we can see, such as galaxies, stars and planets, the density of the universe seems to be below the critical value.
Answer:
The cosmos will continue to expand indefinitely if the mean density is less than the critical density since there isn't enough matter in the universe to stop the expansion. The galaxies will eventually grow progressively further apart. Yes, it will keep growing; no, gravity won't cause it to collapse. The idea of critical mass is outdated. Like "universal gravitation," it is a part of Newton's conception of gravity.
Explanation :
Where that 5% of matter is located, gravity is local. But it upsets 30% of the entire universe (including the 5 percent occupied by matter).
The topography of the remaining 70% of the space is flat.
Dark matter is actually the 25% of disturbed space that surrounds the 5% of matter, not dark matter itself. If the gravitational pull of the universe is great enough, it might stop the expansion and make the cosmos shrink. If not, the universe will keep growing indefinitely. According to the visible matter, like as galaxies, stars, and planets, the universe's density appears to be below the critical level.
