what is going with spin? Everyone says 'this is spin but not its really spinning that's too complicated to explain. can you please at least try to explain it?

i like the way you don't dumb this stuff down. I used to really like a BBC series called “Horizon”, but stopped after it became insufferably watered-down, dramatised, repetitive, and pander-y.

If weak force worked differently: no universe. Kinda sounds like the strong anthropic principle.
Phil G (11 дней назад)
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 (11 дней 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 (11 дней 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?
day Alcober (11 дней назад)
I thought it's gravity that's the problem.

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?
Wonthe Interwebs (12 дней назад)
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 (14 дней 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.

vlharris1 (15 дней назад)
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

ryan knaub (15 дней назад)
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 (15 дней 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.

I literally spent the entire first 2 minutes of this video trying to figure out what the heck were those "Adams" that he kept talking about...
Mike B (15 дней 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 (15 дней 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.

I actually thought this was a buzzfeed video of Adam ruining everything we thought we knew about the weak nuclear force...
Andrew Cannon (15 дней 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.

Hey mysterious force! Why u so weak huh? You must squat whats the matter with you! do u need some concrete pills to harden the FUUUU UP???

Gillemin (16 дней назад)
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 has been causing trouble for a century, ruining everything physicists thought was true. But it might actually be responsible for your very existence." So basically it's the woman of nuclear forces.
