what is the smallest particle in universe? what is its name?

Question

i heard that quarks are produced by particulate matter getting ever smaller, down to the tiniest particle(s). and then, when that happens (where do they go?), they form a quark. what are the names of these smallest particles? and then i heard that a quark (what is that really?) produces ever-increasing larger particles going out and out, creating universe? any concrete answers? any observations/thoughts on this?

Answer 1

The smallest particle that we expect to be there is a quark. Quarks make up all matter in the theorys.

However, if string theory is correct, than a single tiny 1 dimesional string would be the smallest. It would be smaller than anything we can imagine, and smaller than anything we will ever be able to see. The reason that it differs from common theory is that we consider the tiniest building blocks of the quantum world to be zero dimensions, as in a single point. String theory changes the 'point' to one dimension, and allows it to vibrate to create particles.

Answer 2

At the moment, scientists believe that quarks are the smallest particles in our universe and that they form the basis for all matter.

However, just as scientists until the late 19th century believed that the atom was the smallest particle, they may someday discover particles smaller than quarks.

In the meantime, theory holds that quarks, with the help of gluons to hold the quarks together, make up everything in the nuclei of atoms. Up, down, charm, strange, top, and bottom—these are the six “flavors” of quarks. Up and down quarks are the least massive and are more prevalent than other types. Protons always have two up quarks and one down quark, whereas neutrons have two down quarks and an up quark. Other more exotic and more massive particles are composed of other quark combinations. A lambda particle, for example, has an up, a down, and a strange quark, while a kaon has a strange and an up quark. Gluons carry the strong force that glues quarks together to form protons, neutrons, and other particles and keeps them together in an atom’s nucleus.

Answer 3

This is contradictory. If it is v small it cannot shroud anything. Maybe you mean the Higgs Boson AKA the Graviton. This has never been observed and is only theoretical. It is the particle that controls and is Gravity, It has also been called the "God" particle by the press. At CERN in Geneva a very big "atom smasher" is just about to come online and is called a Hadron Collider. It will generate incredible energies that will smash into each other and the resulting "hangover" could very well show up a Higgs Boson. It is to see what the universe was like in the first few microseconds after the big bang. The energy generated has been described as the kinetic energy of an aircraft carrier travelling at 30MPH smashing into the tip of a pin. It has also been postulated that this collider will generate billions of teeny black holes that would swallow the Earth. I hope not.

Answer 4

The smallest particles of matter are the six quarks and six leptons. Three of these, the up quark, the down quark and the electron make up ordinary matter. Each particle has an antiparticle partner that can be produced and studied - antiparticles are not just the stuff of science fiction, they are science fact and can be studied in the laboratory.

Answer 5

I believe the electron is still believed to be a point particle. That is, no experiment has ever been able to show that the electron is not a point with no physical extent. Furthermore, the electron is a fundamental particle. It is not made up of quarks. So I cast my vote for the electron (and other "point" particles) as the smallest.

I don't know if string theory would make an electron non-fundamental, or not.

Answer 6

Quantum physics deals with this, the smallest particles that we can see (sometimes) today. From what I've learned, quantum particles are the smallest particles that we can see/study right now, and they are pretty interesting. See: What the Bleep Do We Know (movie) and also look into quantum physics.

Answer 7

Einstein thought something like 92% of the knowledge of the
universe was yet to be understood so i think we can savely say we do not really know but have only lesser working theories. check out a book on string theory it goes into additional dimensions whooo what will be next? this could become the basis for the generation to come after quantum physics?

Answer 8

Still quarks at this point. But who knows?

Aloha

Answer 9

electrons, neutrinos, and quarks are the smallest particles.
