How big is the universe?There are people who believe the universe is infinite with an infinite number of stars and galaxies. There are some very valid mathematical explanations of why this can't be true. However, as in many other theories of the universe, we simply don't know.With the most distant objects we can see, estimates currently are that the universe is over 156 billion light years across. Some theories say that the universe is expanding at close to the speed of light, so we can't even conceive of traveling to the edge of the universe to measure it.

How big is an atom?A:A piece of dust is exactly half way between the size of the Earth and an atom. A:Atoms are pretty darn small. Their outer boundaries are set up by moving electrons, so they aren't well defined. Their diminutive proportions coupled with the fact that they don't have a definite "surface" make assigning them a size something of a challenge.

The helium atom is about 1 angstrom in diameter. An angstrom is 10-10 meters, and that means that there'd be something like 1010 atoms of helium in a meter. Picture a pencil eraser. It isn't that big. Roughly 70 million atoms of helium could be lined up in a row across the eraser. The largest atoms are maybe 7 times larger than helium. At that rate, there are maybe 10 million of those big guys in a line across that eraser.
