When you shoot a beam of subatomic particles in between specially shaped magnets some curve one way some curve the other way. Nobody knows what property is causing this so we label it spin because spin is binary. Particle spin is treated like it is some elite concept that can't be understood by regular people.

Weak force is the remainder in multi-dimensional projection? the criss of an otherwise perfect bend. You just can never get a perfect right angle. there are always leftovers.

How do we know that distant galaxies arent made of antimatter, giving the universe as a whole roughly equal distribution? Since the only difference between the two is the charge of the particles, shouldn't antimatter galaxies emit detectable electromagnetic radiation?

Leo Yohansen (11 дней назад)
Weak with you is the force. The weak force is actually the star of the forces. Its separation from the electromagnetic force caused inflation and a universe that favored one form of matter over its anti-counterpart.

Interesting video SciShow! I’m would like to learn more about how the universe is both expanding and a hologram at the same time and how that fits in with the world as we know it including the laws of physics that govern everything.
it only ruins things for simple minded people who can't comprehend that their answer isn't the right answer

So can weak force give time its direction? I have heard that only the second law of thermodynamics give the direction of time.

If weak force worked differently: no universe. Kinda sounds like the strong anthropic principle.

you'd have to be a delusional over-dweeb to claim anything in modern physics is intuitive or self-evident.. 'sooo uummm yes the strong force causing particle transmutations, totally get that, makes perfect sense to meee, but the weeeaaakkkk force? noooo wayyyy!!!'
AutodidacticPhd (2 месяца назад)
Ok, but, all I've heard my whole life is that gravity is the weird one out. It is spectacularly weak, even compared to the titularly weak force. Gravity is the one that needs a whole theory all to itself, which can't play nice with the theory that (at least until now) I've always been told covers the other three just fine... so, what gives?
R. Organizer (2 месяца назад)
So if the weak force allowed matter to survive anti-matter annihilation, does that mean that the meek will inherit the earth thanks to the weak?

I'd love to know more about migraines. I've been having them since middle school and I've seen the videos you've made on the topic. But migraines are just such a weird happenstance. I get the 'normal' triggers and signs, but I also get some stranger ones. Occasionally I smell artificial grape before a migraine hits; sometimes it's burnt toast (I swear it's not a stroke). Other times I completely forgot how to read or write, and that's my only warning. I can't be the only one with these pre triggers.

So if the weak force is the only force that seems to violate time reversal symmetry, does that imply it is responsible for entropy?

This all makes sense if antimatter is time reversed matter.

The Weak Force is the non-PC force with some anti-T tossed in for good measure. #PCToo movement
tentor (2 месяца назад)
The weak force violating T symmetry is actually a good thing. With CP already broken, breaking T too is the only way to maintain CPT.

Unsafe assumption on more matter than antimatter. Could just be uneven distribution in space and that means universes are just clumps waiting to get annihilated. But they haven’t yet met their anti clump. Which is sitting there as an anti universe now... TM me on this theory!

The combination of the electromagnetic and weak nuclear force gives the electroweak force which predicted the fact that radioactive decay is not constant but is changed by a strong change in the sun’s magnetic field

great revelations in science are almost never an "Ah-HA! I've found it!" type of moment. They are almost always "Hmm.... that's not what i expected...."
Michael Clark (2 месяца назад)
How does the electroweak force fit into this? Wouldn't combining the symmetry breaking weak force with the elecromagnetic force break symmetry as well? Which brings us to the vector bosons W and Z, maybe they are responsible and maybe they work on the Bo to anti Bo and vv. at different speeds, (different gauge or vector bosons moving at different speeds?) Still breaks symmetries but we would know the mechanism.

Mike B (2 месяца назад)
All these arguments of symmetry that MUST be valid for so & so to work, almost like that's the axiom, yet how many times in history have we gotten dinged in science because we came up with the axiom of "perfectness" or something similar? Looking at you Mr Uniform Circular Motion who's axiom had us denying the idea that the Sun was at the center of the solar system just because the model didn't work

Is it possible that at the time of the big bang equal amounts of matter and antimatter was produced, but antimatter traveled in the opposite time direction?
honkatatonka (2 месяца назад)
Uhm, if I understand correctly, matter/particles didn't exist at t1 but condensed *after* the big bang. So why do we say the big bang produced matter+antimatter? Didn't both exist after some time has passed? Or did I get that wrong?
Hi, Hank, you asked for it, so here's a case. It's about gravity - mass attraction - and inertia. We can hide the effect of gravity with a variety of tricks. For example in  a falling elevator. And with some other tricks as well. But whatever we try and do and do, we cannot hide the effect of inertia as a mass is set in motion from rest.

Andrew Cannon (2 месяца назад)
I like your video. But the truth is right in front of you. Unfortunately for most theories they are at the least very flawed. Think about what you say about what makes up an atom. Are these subsets found in abundance? And ask yourself again,why is the universe expanding? Take into account the Higgs field.

In the standard model there is also another possible source of CP violation. That is in the strong force or more precise a complex phase in the strong force. Now the CP violation in weak decays is described by a complex phase in the quark mixing. Both these phases are not prediced in the SM but have to be measured. For the weak force this has been done but produces not nearly enough CP violation to account for the Matter-Antimatter asymmetry in the universe. Whoever if we set the strong phase to anything else than 0 there would be to much CP violation. This is called the strong CP problem. So in generell the strong phase is set to 0 and everything continues working, but there is no good reason for it to be zero, besides easier calculations. In the end the strong force or better the theory of Quantum Chromo Dynamics (QCD) is so hard to calculate anyway, that we have no idea if the phase is not zero and our calculations about CP in strong decays are just super off or if the phase is actually zero.

The weak force screwed me over to, i had some scrap iron to sell and had to take it through a radiation detector at my local scrap yard, and it went off....
