Is universe mass infinite?

We can consider the universe to be infinite from our point of reference . But we also know that the universe is mainly empty space. However, we do not know (and may never know) the true shape and extent of the universe so we cannot claim that it is truly infinite. Therefore, the mass of the universe is finite.

What would be bigger than the universe?

No, the universe contains all solar systems, and galaxies. Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy, and the universe is made up of all the galaxies – billions of them.

Is the universe infinitely large?

No one knows if the universe is infinitely large, or even if ours is the only universe that exists. And other parts of the universe, very far away, might be quite different from the universe closer to home. Future NASA missions will continue to search for clues to the ultimate size and scale of our cosmic home.

What is the mass of the universe?

As nobody knows the size of the universe, one cannot really talk about the mass of the universe, though one can talk about the mass of the observable universe. What is normally sought after is the density of matter in the universe (which is the mass per unit volume).

What are some of the assumptions of the infinitely expanding universe?

Nothing else. More stars, galaxies, and clusters in an infinitely expanding space. This would also make this theory similar to another assumption called “Multiverse Theory”. If space truly expands infinitely, then there must also be infinite repetitions of our own universe, our own planet earth.

How many galaxies are there in the universe?

Now, the size of the observable universe is about 14 billion light years, and using the above value of density gives you a mass (dark and luminous matter) of about 3 x 10 55 g, which is roughly 25 billion galaxies the size of the Milky Way.
