Is There Anything Smaller Than Quarks

09 Apr., 2021

Based on the evidence available today physicists think that quarks are elementary particles. My guess is that black hole singularities are quite a lot smaller than a quark but I dont believe theyre of infinite density Parker told LiveScience.

The sizes of atoms nuclei and nucleons are measured by firing a beam of electrons at an appropriate target.

Is there anything smaller than quarks. Most likely they are maybe a million. That means they arent made up of anything else. It is named after physicist Peter Higgs who in 1964 along with five other scientists proposed the Higgs mechanism to explain why some particles have mass.

In the Standard Model there are 6 leptons 6 quarks 4 bosons and 1 Higgs Boson with a total of 17 particles. Or they rather improbably may. Nothing yet discovered although there is some speculation that there are too many varieties of quarks 18 if you count flavors and colors for them to be the fundamental particles.

At the present time quarks are considered fundamental ie. Indeed they contain still smaller particles which are called quarks. Fredrik Sandin and Johan Hansson of Luleå University of Technology in Sweden say that.

Atoms are made up of protons neutrons and electrons. In other words they have never been shown to have any size at all. Perhaps so if quarks the constituent particles of atoms are themselves made up of still smaller particles.

Particles that are smaller than the atom are called subatomic particles. They exist only as free quarks and then decay. The idea wasnt entirely fanciful but raises further as-yet-unanswered questions.

For the time being most physicists believe that quarks electrons and all other particles are best described as being vibrations of superstrings multi-dimensional entities far smaller than the smallest sub-atomic particle. The Higgs boson is an elementary particle in the Standard Model of particle physics produced by the quantum excitation of the Higgs field one of the fields in particle physics theory. Well theres only one possible answer and that is they could The quarks and electrons and by extension all leptons could be made of even smaller objects.

David Gross Nobel Laureate in Physics 2004 has answered a selection of your video and text questions from YouTube and Facebook including his explanation o. Thomas Ryttov and his colleagues believe that the so-called techni-quarks can be the yet unseen particles smaller than the Higgs particle. Thus protons and neutrons are no more indivisible than atoms are.

If the explosion of the big bang was large enough or the mass of the universe is too small then all the galaxies the universe will continue to accelerate away from each other for an infinite amount of time and never stop. Are there free quarks. At the beginning there was LESS complexity and the smaller you go quantum scale the less particles you have to worry about and should therefore be LESS complex than the macroscopic world.

All we know about the size of quarks is that they are smaller than the resolution of any measuring instrument we have been able to use. If techni-quarks exist they will form a natural exention. The smallest quarks up and down dont decay into anything else although they do transform into each other.

Following the discovery of quarks inside protons and neutrons in the early 1970s some theorists suggested quarks might themselves contain particles known as preons. Quarks are thought to be fundamental particles - they cannot be broken down into smaller pieces - and as such we treat them as being little geometric points. Particles acquire mass in several ways but a full.

Smaller than quarks are various leptons such as electrons and neutrinoes. Electrons photons neutrinos are also treated as being geometric points. It makes no sense that the smaller you go the more elemental particles you end op with.

Following the discovery of quarks inside protons and neutrons in the early 1970s some theorists suggested quarks might themselves contain particles known as preons. Protons and neutrons are made of even smaller particles called quarks. Which cannot be broken up into anything smaller.

Eventually everything will be so far away from each other that even with the best telescopes on earth we wont be able to see any other galaxies. Quarks are as small as or smaller than physicists can measure. A quark is a fundamental particle that is smaller than any measuring instrument we currently have but does that mean theres nothing smaller.

Its not always meaningful to talk about the sizes of particles.
