There is no reason to think so. However, we have no evidence to make a conclusion either way.
A googol is larger than the estimated number of atoms in the observable universe.

the universe can not be everything because there has to be space for it to expand into
Our Milky Way is about 100,000 light years across. Some galaxies are larger than that, some are smaller.
Someone claimed that my claim that the size of the universe is not falsifiable is not correct. Their answer is for the visible universe whose size is falsifiable. My UNFALSIFIABLE size is for any postulated universe larger then the Hubble radius (distance where expansion of space rate becomes the speed of light). We CAN'T measure or deterct anything in space (or know, in physics, if such regions of space even exist) that is expanding faster than the speed of light. Therefore we can't falsify a measurement that is impossible to make.

-- The Milky Way is one of several billion galaxies in the universe. -- The term 'universe' means "Everything ... all things, all space, and all time". -- Considering either of these factoids, it becomes apparent that the universe is larger than the Milky Way.
The universe IS space, plus everything that's in it.
The universe contains countless galaxies, think of the universe as a galaxy of galaxies.

The amount of empty space in the Universe, between galaxies, is many times larger than the amount of space occupied by galaxies. This ratio depends on what part of the Universe you are looking at. For example, our galaxy has a diameter of about 100,000 light-years; the closest larger galaxy (M31) is at a distance of about 2.5 million light-years. However, that's just the Local Group; from the Local Group to another galaxy cluster, there is even more empty space.
yes most of the universe is empty space
Everything in space is part of the universe or cosmos.the universe
NASA Space Universe was created in 2006.

the answer is complement
