What's the smallest thing in the universe?

A quark or an electron. Sep 22 02, 6:14 PM

Quarks are pretty big compared with electrons, as far as I remember. The smallest quark is about 600 times as big as an electron (in terms of mass). The photon, the packet of energy which is transmits light, is even smaller than an electron, I think. But there are various theories which have strange particles such as gluons, tachyons, neutrinos, etc, which are all very small. Sep 22 02, 9:47 PM

The following site zooms out to Scale: 1025 meters = 10 Ym = 10 yottameters (~109 light years) or in to Scale: 10-16 meters = 100 am = 100 attometers. It really is very interesting and informative. http://www.wordwizz.com/imagendx.htm Sep 24 02, 6:47 AM

The smallest particle in the universe is not the quark; it is the Perpetual Motion particle. It is the only thing that keeps the universe in constant motion. Because it is in a constant state of agitation generating heat causing it to be in motion all the time. It is bipolar, both positive and negative like a magnet. Controlling its environment around it, the more it moves the more energy it creates. It came to be during the Big Bang. It is the envelope, which holds the universe together. http://en.wikipedia.org/wiki/Perpetual_motion Sep 25 07, 11:51 PM

Can I request the removal of rayirizarrysr's answer above? The article sourced doesn't mention the supposed particle, and the only sources I can find for it are unreliable parrottings of the same info with no sound source mentioning this particle. "Controlling its environment around it, the more it moves the more energy it creates" - this is complete nonsense. Energy is not 'created' - it can be transferred or matter can be converted into energy (and vice versa). "Modern theory holds that neither mass nor energy may be destroyed, but only moved from one location to another." "Matter, when seen as certain types of particles, can be created and destroyed, but the precursors and products of such reactions retain both the original mass and energy, both of which remain unchanged (conserved) throughout the process." http://en.wikipedia.org/wiki/Mass%E2%80%93energy_equivalence Dec 29 10, 8:18 AM

what about trinitrons...? i heard that they were the smallest particles in this universe lately discovered Nov 27 11, 9:53 AM

Hsn111, although you know the answer to your question, I would like to verify on this page as well that trinitrons are not particles at all, they are a brand of television. http://www.funtrivia.com/askft/Question124273.html http://en.wikipedia.org/wiki/Trinitron Dec 17 11, 10:05 AM
