How to pronounce “atomic nucleus” in English

was a nuclear reactor it was a fusion reactor at very very early times the temperature was so high that youcouldn't have an atomic nucleus you couldn't stick together protons and neutrons they would smash into other nuclei and they would break apart butthe universe is expanding and cooling so what you do is you start at 1 second after the big bang with free protons and

smaller than a certain amount the smallest distance that we have probed in our Laboratories roughly a 100th thesize of an atomic nucleus if but if we calculate the amount of energy in spacedue to fluctuating Fields like the electromagnetic field and the gravitational

So you build one of these detectors, and then you realize that what we're talking about, the stretching and squeezing, is much smallerthan the size of an atomic nucleus across the length of these arms of these detectors.OK? And so when you in the lab order pizza and the pizza delivery truck shows up, that's enough rumbling in the ground

This is actually substantially larger than what we talked about with the LIGO detectors, because there we were talking about kilometer-long thingsmoving by the size of an atomic nucleus.This is actually a larger string than that.

that is holding holding those electrons to the neutrons and protons and therefore there are photons that are passing back and forth in between theelectrons and the nucleus of the atom if you zoom in on the atomic nucleus if you zoom in past the neutrons and protonsyou find that they are made up of quarks every proton has two up quarks and one down Quark every neutron has two down
