Is there anything, anything at all, smaller than an atom?

Answer 1

The smallest particle that has mass is a neutrino. I will not give you all the flavors of neutrinos. Let's just say that for a long time no one was certain if it even had a rest mass.

That it now has a rest mass is important on a big scale. It seems that the math is such that adding in the masses of all those neutrinos running around, the Big Bang expansion of the Universe will not continue indefinitely. Instead, the Universe will eventually come back together again.

I knew you would be comforted by that. Somehow it seems just a little less lonely, doesn't it?

Answer 4

An atom is defined as the smallest unit of which an element is composed. Atoms are made up of sub-atomic particles, i.e. proton, electron, and neutron. Sub-atomic particles are made of of even smaller things of which quarks are one.

Photons and anti-neutrinos are also particles which are smaller than atoms.

Answer 5

Along with the neutron and proton (inside the atom) and the electron (circling the atom) there is also the photon (small packet of light in a wave), the quark (associated with mass), the gluon, the lepton, and the tachyon (hypothetical particle) just to name a few.

Look up fundamental particles or elementary particles.

There are lots out there.

happy hunting. bring a real good magnifying glass. haha.

The Margarita atom (Mg) is my favorite. But the Kamikaze atom (Kz) ain't to bad either.

Answer 6

'It has been said that during the 20th century, man harnessed the "power of the atom." We made atomic bombs and generated electricity by nuclear power. We even split the atom into smaller pieces called subatomic particles.'

Answer 7

Generalist theorists say that the smallest common particle is the quark.
However, some physicists and chemists, whom I am associated with, will argue that elemental wavelengths as related to spacial displacements ascertain an infinite "smallness" of never concluding proportions. In this example, we see that as there exists an infinite "bigness", there also exists an infinite "smallness". As we look at smaller and smaller particles, we see that not all matter is associated with density, mass and volume, rather the smallest representations of material is associated with wavelengths; photonic building blocks and objects that displace the presence of light and energy. At this size, it is important to understand that displacement of light energy is the defining explanation of a material and further identifies an infinite smallness.

Answer 8

space is infinate ,it is impossible for there NOT to be something smaller than atom ,...then smaller,.. then smaller than that till you get to something that makes an atom look like the universe we know. Then you keep getting smaller,forever and ever. Till you see my brain there.

Answer 9

always.As the smallest cant be reached as it is out of our range.we shall be hearing the news in heaven when a more precise particle would be found -soumyadeep das

Answer 10

yes, protons, neutrons, and then much smaller electrons, then the components that make up those (quarks) and then when you really get small, strings that are really just energy.
