What Is The Smallest Particle We Know?

We have built beautiful particle accelerators in the search for particles that are even more elementary than electrons, protons, and neutrons.

The accelerators smash subatomic particles at enormous speeds, which causes them to shatter into their constituents. It is similar to studying the inner mechanisms of television by throwing it from the top of a 20-story building and scrutinizing its broken components. When physicists first began colliding electrons with protons, they observed that electrons bounced off three small hard cores inside the proton. The cores were found to be even smaller particles that make up the proton. These elementary particles are called Quarks, and the discovery of quarks meant that protons and neutrons weren’t fundamental anymore.

accurate, there is no end to how small things can get as everything needs to be made of something. Like our known universe being on an atom of a giant.

There is no such thing as smallest particle or thing. There is an infinite number of smaller things. Those awarded Nobel prize can continue to get prizes as long as enough energy is available to smash particles together. This can be done infinitely

I find it difficult to conceptualize something that all things are conditioned by, something that MUST exist in order for other things to be able to manifest their existence in nature and form reality as we sense and experience it. A "something" so fundamentally present, and which by virtue of its own existence, gives all other things in the universe an essence or identity, whose inherent properties represent reality itself and convey a deeper understanding of the meaning of existence in human consciousness.

r[m] =
(htrans/c).(1/m[kg])

and for the mass of the universe ~1E54 [kg] it is r~1E-97 [m] in the case of BigCrunch. The smallest conceivable size (for this mass).

Prefer to use the SI system and this form of numerical expression. Otherwise you are confusing the reader.

WOAH I never knew this, Your so underrated

[knarftrakiul]

I bet just as the universe is vast its the same way in opposite direction. I say particles keep getting smaller that it will take millions of years to reach the smallest

[briankleinschmidt]

Probably not billions of sand grains in a standard sand castle. Maybe that many on the beach.

[dinkylinker]

So a positive charged proton may same as our sun?

[briankleinschmidt]

There are no fundamental particles. A particle becomes empty space over time. We are made of energy.

[solomonnazareno]

Everything is infinite, there is always a smaller than smaller of smaller atom particle or whatsoever,

[gzl]

It is said the most powerful thing is the "thought", someone explain endless imaginative whatever that appears in our thoughts/dreams?

[Camouflagecornandpumpkin]

Actually, the next is the molecule, and then the atom

[kamal]

Why didn't u mention about the String theory??

[thetruthhurts]

Could there be proton planets that have life on them?

[sandeepkumargupta]

call inventor, discoverer or thief...
