The Planck Mass: Not extremely big and not extremely small
Ғылым және технология
I’ve looked at most of the Planck units. Planck length which is really tiny, Planck time which is really short and Planck temperature which is really hot, but there is one I’ve been sort of putting off, and that is Planck mass, which is kind of strange, let’s find out more.
Unlike my other Planck unit videos we don’t need to try to use our imaginations to visualise how big or small this is because we can easily imagine how heavy this is. This is about 10 times heavier than a human egg cell or about the same mass as a human eyelash. So how does this compare to the mass of other things. Specifically how does this compare to the masses of particles and the like.

It's worth mentioning, the top quark isn't the largest quark, merely the heaviest. Quarks have the peculiar property of being smaller the heavier they are. So the top quark is actually the smallest quark in terms of size.

All particles have a greater spread the less massive they are. That's why protons are more well defined in terms of position than electrons. If you look at a model of an atom, you have a tiny point surrounded by a large diffuse electron cloud.
There's another Planck unit which is the weight of a small sea creature that whales eat. This is called the Planck Ton.

Interesting point thats often missed: There arnt just 3 quarks in a proton and neutron, they are something of a soup of quarks and anti-quarks popping in and out. The three valence quarks that are often treated as the only quarks around are the imbalance. I.e. there are two more up quarks and one more down quark than their anti versions.

Thank you so much. That gives me a better, established term for what is really going on. 1. The total energy at every point is a constant. (Planck mass equivalent) 2. There is no such thing as negative energy. 3. Spacetime is a field of potential energy, governing motion.

The binding energy of particles, like an electron in an atom, is often given as a negative number, because it's relative to a free, unbound electron. There can also be things like negative heat given off by a chemical reaction (i.e. it's an endothermic reaction). But if you're just talking about the energy content of a particular patch of space, that's measured relative to the "ground state" which is a minimum, so I guess in a way you could say it's always positive. But it's all relative to something. That ground state might not be zero. See vacuum decay. If the energy at every point was a constant, there wouldn't be any curvature of spacetime. There wouldn't be much of anything.
@themcchuck8400

@@DFPercush There is no "negative energy" that subtracts from energy to leave... nothing. There are things we arbitrarily label "negative" for convenience, but it's still energy. There are opposites, but there is no "anti" energy. Spacetime potential energy + every other form of energy = constant. The gradients in each field (especially spacetime) are why acceleration (and motion) exist.
Is the Plank mass related to the diffraction limit? i.e. things with mass up to the Plank mass, can diffract, by lesser amounts until something bigger than the Plank mass won't diffract, or experience much quantum effects?

Roger Penrose suggested that Planck mass is roughly a threshold where quantum mechanics turns into classical one (with general relativity). Something like: superposition of many states may exist as long as they don't differ by more then planck masses's worth of energy. Then wave function collapses and some photon which was 'everywhere' ends up in one particular point.

Is the plank mass the amount of mass needed to permeate the quantum vacuum for an area the size of the Plank scale and become a singularity?
At plank units, as the sizes get smaller and interactions fewer doesn't the temperature tend to zero or cold rather than hot?
When any elementary particle reaches the speed of light,its relativisic mass becomes equal to Planck's mass instead of becoming infinite,its size becomes equal to Planck's length instead of becoming zero and its lifetime becomes equal to Planck's time which is the evaporation time of the smallest possible black hole according to Hawking(see papers on "The Principle of Finiteness" in arxiv and JOP by Abraham Sternlieb).This requires certain corrections to Lorentz Transformations and to the Uncertainty Principle which are compatible with string theory and Quantum Gravity.
Very good
Hey i heard in some other video that in neutron stars, neutrons are formed when a proton and an electron are smashed together. If that is the case why does a neutron not have an electron as one of its constituents.....🤔
If anything, this just goes to show how ludicrously compressed a black hole really is. Something with a size that makes even a neutrino look like a nebula, with a weight that, for anything else, would be visible to the naked eye.
A particle having plant mass in a size of plank volume should be a black hole with plant density.. right?
Though I wonder then, if you've got planck time (time can't be measured any smaller) and plank length (distance can't be measured any smaller) then what would you call the smallest possible measurable unit of mass?
At the beginning shouldn't there be also a momentum component? And wouldn't it throw out the calculation for mass?
The binding energy is not all of the remaining mass of protons and neutrons. A large majority of the " missing mass " is due to the inertia of the quarks being tugged back and forth like a carnival ride within the internal structure of the hadron. Inertia will always translate to mass.
I think the interesting thing about the Planck Mass is the density that it infers, which is about 5.1550×10^96kg/m^3. This is much much more mass than is in the visible universe, in a 1m Cube.

Well, what this video fails to report, is that the planck mass is the largest mass a single fundamental particle can theoretically have without immediately collapsing into a planck size black hole. It is equivalent to a microgram, approximately. So that density, could be correct. I will not even try to confirm, my math is bad.

Just a detail and major discovery on gluons a few weeks back which was major discovery in particle physics but either misrepresented by science journalism or totally overlooked by them. in terms of the detail, the gluons would look like a cloud if you could image it. similar to the electron cloud in the orbital ''shells'' of the outskirts of atomic nuclei. individual gluons were isolated and found to possess an infinitesimally tiny mass.when i say individual gluons i mean in a quantum sense. really the wave-particle duality thing of basic quantum mechanics was dismantled with quantum field theory in which really they are more akin to waves, which are quantised, meaning they have discrete energy levels and so form wave packets. when we do a position value measurement the wavefunction superposition of the photon/electron/neutrino/muon e.c.t. collapses and assumes one more localised value chosen at random but generally choosing points where the probability of it turning up was highest .it is never a point particle, but merely a more localised wavepacket, because heisenberg uncertainty principle means there is always some uncertainty over the position-so the position can never be 100 percent known and the momentum can never be zero known, therefore. so its clouds and waves we should think of in regard to the gluons and quarks. in terms of gluon study recent measurements and discoveries at the jefferson lab have answered once and for most of the mysteries surrounding the gluon binding mechanism and mass. the study was published under the title ''experimental determination of the QCD effective charge''. the gluon discovery was therefore accidental but is definitive as it comes from an entire decade's worth of data from smashing electrons at protons and neutrons in particle colliders. previously the gluon binding mechanism of QCD has been represented as a rubber band analogy in previous simulation images. and while this is probably still the best intuitive analogy, we now have a new more accurate simulation of the strong force coupling produced by jefferson lab and MIT jointly. its actually the kinetic energy of the gluons that provides the majority of the mass of the proton and neutron. i find it best to think of mass as confined energy manifesting as resistance to inertia. quarks seem to gather up gluons to themselves as the quarks move around, and the quarks acquire the gluons binding energy, causing the quarks to be strongly stuck together by the strongest known superglue in the universe-the strong nuclear force. the quarks gather more of the gluon field to them, as the quarks move across larger distances.at the shortest distances from the quarks the strong force coupling is actual relatively weak. it increases with greater distances but then it stops increasing, staying prettu much at the same coupling strength. but i suppose this is like a rubber band that has been pulled as far apart as it possibly can go. the gluons themselves therefore, get their really really really tiny mass from the strong coupling force between themselves and the quarks.
It's like the substrate to the universe. As if there was a layer of energy 90° to us moving at c.
The physics of QCD surely induces madness in the mind
