Sentences with phrase «than a proton into»

They should help us to hone descriptions of how, after the big bang, the universe grew from smaller than a proton into a vast expanse in less than a trillionth of a trillionth of a second.

Not exact matches

At time = 0 the infant universe was smaller than a proton and at that scale quantum mechanics allows for some pretty weird things... including particles popping into and out of existence.

Pagels (1984) points out that if the relative masses of protons and neutrons were different by a small fraction of 1 per cent, making the proton heavier than the neutron, hydrogen atoms would be unstable since the protons that constitute their nuclei would spontaneously decay into neutrons.

In their paper, «Higgs Seesaw Mechanism as a Source for Dark Energy,» Krauss and Dent explore how a possible small coupling between the Higgs particle, and possible new particles likely to be associated with what is conventionally called the Grand Unified Scale — a scale perhaps 16 orders of magnitude smaller than the size of a proton, at which the three known non-gravitational forces in nature might converge into a single theory — could result in the existence of another background field in nature in addition to the Higgs field, which would contribute an energy density to empty space of precisely the correct scale to correspond to the observed energy density.

If those protons were just 0.2 percent more massive than they actually are, they would be unstable and would decay into simpler particles.

Report on results from Germany as physicists probe deeper than ever into the humble proton

When protons start colliding in the LHC — in the test run in September, they ran just one way around the track — they will each carry no more energy than 14 flying mosquitoes, but this energy will be crammed into a space one - trillionth the size of a mosquito.

Two other companies, Energy Matter Conversion Corp. (EMC2) and Tri Alpha Energy, are developing reactors that use proton - boron fuel, which requires even higher temperatures than deuterium does but allows almost direct conversion of fusion into electricity, without boiling water to drive a generator.

By collecting and storing antiprotons for reinjection into the main accelerator, the 1.9 - mile (3.1 - kilometer) Permanent Magnet Antiproton Recycler Ring more than doubled the rate of proton — antiproton collisions the Tevatron could produce, allowing it to stay at the cutting edge of particle physics.

Because the strong force holding the protons and neutrons together is stronger than the electromagnetic one, knocking the nucleus apart into pieces demands more energy than removing the electrons.

And because the disc rotates at about the same speed as the Milky Way, WIMPs might collect in the sun more often than you would expect, knocking into solar protons to produce neutrinos.

Proton rockets have been launched more than 200 times since 1965, with a success rate of 96 percent, and have lifted the Zond, Venera, Mars, Vega, and Phobos interplanetary probes into space, as well as manned Salyut, Kvant, and Kristall modules.

«The cool thing about our results is that we found that when you squeeze water into the nanotube, protons move through that water even faster than through normal (bulk) water,» said Aleksandr Noy, an LLNL biophysicist and a lead author of the paper.

Across the continent, people were lining up by the millions on one side or the other of a new binary system, being told they were «positive» or «negative» as if they had turned overnight into protons and electrons and everyone spoke of subatomic physics, rather than of who was going to live and who was going to be shunned, endure terrible suffering, and die.
