Are we smaller than an atom compared to the universe?

The observed universe is about 100 billion light years across, or about km. That’s about times the size of a human being. An atom is in the region of 100pm in size, or times the size of a human. So an atom is much, much bigger compared to us than we are compared to the size of the universe.

Is the universe like an atom?

In fact, the Universe we see through our telescopes may be just the collection of billions of atoms that are in a larger Universe. Perhaps we are even part of the atoms on another gigantic living being!

Can there be things smaller than atoms?

Thus, protons and neutrons are no more indivisible than atoms are; indeed, they contain still smaller particles, which are called quarks. Quarks are as small as or smaller than physicists can measure.

How much smaller is an atom than a cell?

A cell is about ten times larger than an atom.

Are atoms made of smaller atoms?

Atoms are made up of a nucleus, protons and electrons. We now know that atoms are made up of three particles: protons, neutrons and electrons — which are composed of even smaller particles, such as quarks. Atoms were created after the Big Bang 13.7 billion years ago.

Is there a hidden universe inside of an atom?

There can be no hidden universe inside an atom. Planck’s constant sets an absolute scale for physical objects. Fantasy movies about shrinking people to microscopic size are just that: fantasies. It’s categorically impossible.

Is the universe bigger or smaller than a hydrogen atom?

If you’re talking about a big atom, then the atom comprising the universe cam be smaller. But, if, we suppose, we know all the elements, and the smallest is hydrogen atom. Then the universe will be equal to the size of the hydrogen atom.

Does the universe have a center of matter?

The universe of course doesn’t have most of its matter centered in the “middle” but rather has fairly spread out mass. However, if you are referring to the fact that most of the atom’s space is empty being similar to the universe then you are correct. The universe also has a huge amount of empty space between stars and galaxies.

Is there anything smaller than a quark?

For example, if we look past an atom, we might say there is nothing smaller than quarks (due to our technical limitations), but if we compare the size of Earth on a universe scale, looking through a telescope from outside the universe, the size of the Earth would be equivalent to a quark particle…
