Why is There More Matter Than Antimatter in the Universe? 

Today I learned that bananas make antimatter.

Tara Shears needs to instruct all other instructors on her fantastic method of conveying information to make it such an enchanting experience.

Good video. Explained clearly and interesting.

Before I knew how everything worked, I believed that the reason there was more matter than anti-matter, was because at the birth of the universe there was an equal amount of matter/anti-matter, but because they would collide and explode, a huge amount of energy would be released, and I had just learned that energy=matter, so by adding 1matter and 1 anti-matter, you would end up with 0.5 matter or something. Than I learned that anti-matter is just the same as matter with the charge being negative instead of positive, and that whole theory went down the drain. Yeah, made no sense, but I was 14, so I wasn't realy well educated in physics at that point.

She is a scientist and she obviously knows more about the subject than many of the viewers but I doubt many of the leading researchers on the topic would be able to present or explain this top as beautifully as her. She knew exactly how much to divulge and how to pace herself. Normally, I have trouble getting a British accent but she spoke well.

Very interesting subject and also top presentation skills

Thank you for this video Tara.

You should have titled it "What's the antimatter with antimatter?"

TLDR: we don't know.

how do we know for shure that we are not simply in a region of the universe with more matter than antimatter?

after finding enough CP violating particles next question what causes it and can the cause be replicated artificially, potentially creating universes, riiight? Cool video btw, thanks

I am able to take Bach's Partitas and flip them up side down, on the computer. I have to raise or lower the parts an octave or two in order to keep it in bounds. A remarkable thing happens when the catastasis is reached. I have to adjust just a few bars to finish the accumulating idea, that is absent from the original. That's the result of a matter, anti-matter relationship, in music. Considering the very same frequency relationships exist in both Bach's music and the frequency relationships between subatomic "particles," (DeBroglie waves), this anomaly is very interesting to me.

I wonder if there even is a way for us to do accurate experiments, when it comes to figuring out the things that happened in the early universe. Maybe the conditions were just too extreme for us to replicate at this point in time.

The issue I take with this line of thinking, is that we named "matter" and "Anti-matter" . So if "Anti-matter" was abundant we'd still be made of matter and "Anti-matter" would be hard to find.

Given the distance between galaxies, is it possible that some galaxies are made of matter, and others are made of anti-matter? If anti-matter galaxies existed, would photons from an anti-matter galaxy be any different from photos in a posi-matter galaxy? And could photons and gravitons from a posi-matter galaxy travel through an anti-matter galaxy in the same way they travel through a posi-matter galaxy?

Because the folks who ordered matter skipped out on the bill?

Is it a coincidence that Physics girl has also uploaded a vid on Anti matter? It doesn't matter........

We used to have matter and antimatter all over the place, but they couldn’t get along and annihilated each other in a big bang

so - how do we know that like 50% of all galactic clusters are not made of anti-mater? is there some astronomical way to tell? perhaps its still 50/50 in the universe... just clumpy. or like ripples in a pond.

How do we know that we are in the matter universe and not the anti matter one, have we got the lable wrong as we did with electrical current flow. For all we know there could be people in the anti matter universe who think we are anti matter.

Hmm. I'm just wondering if charges have mass. If they do, is the mass of a positive charge the same as that of a negative charge? If not, could this be significant in some way? If they don't have mass, do charges interact with the strong force in the same way? If not, could that be significant? While its logical to assume that there could be other particles that we don't know about, could it also be that our understanding of how the particles we know about interact that needs looking at as well? I'm sure that's being done, its just something that came to mind. :o)

Great voice.

Didn’t ‘missing’ bb antimatter simply travel in the opposite direction in ‘time’?

Could it be possible to extend the life of an antimatter?? If it's possible then how??

Dr Shears - genius.

It is a word play. Is there more down than up places ?

why is the question ??? but they answered how you can detect the violation as usual ....

One possible explanation for the asymmetry in the earlier Universe would be if the Universe came into existence at the EH of an existing Blackhole then it may be possible that the missing Anti-matter particle fell into the Blackhole and the Matter particle escaped to become form the Universe we exist in.

We know that what we "think we know" doesn't explain everything, so maybe we don't really understand what we "think we know" or maybe there's a lot more out there that we don't know at all.

Why do they annihilate when touching. Just a different charge? That doesn't happen when touching normal opposite charge stuff.

I dont understand why they assume equal amounts were present at the outset

What about the decay of free neutrons? Doesn't take long, and produces 2 matter particles that can destroy 2 anti-matter particles.

The CMB may have come from a lot of matter and antimatter which annihilated during bigbang....

I'm wondering how many guesses are here. That the matter = antimatter at the outset is one. That the traces detected by LHC ARE indicative of Dmesons (and nothing else). That we could detect antimatter well enough to assert that there is less (example, if it decayed, could it have decayed into some form we have yet to detect or even conceive ? )

Explaining why they thing big bang energies and densities would produce 50% distributions sounds like philosophy until she explained they used the collider to reproduce theses conditions and got that result. The difference though are stark, a near vacuum with near zero expansion of space time for the experiment while the big bang had near black hole densities and near infinite (compared with current expansion) of space time, I think apples and oranges are closer than those to states.

Does the fact bananas make antimatter explain why they are so often claimed to help slimming?

could it be hidden away in extra spacial dimensions?

Unanswered title question in Ri video feels wrong

Too much anti-matter was used to power the ships on Star Trek.

Because there's an infinite time duration timing sequence of quantum orbital, in holographic resonance imaging, at the symmetrically balanced Universal Singularity, perceived as a Single Side Band wave-package, unitary probability-envelope Conception of Spinfoam Totality. "The very first moment", the implication of the Planck Dimension as the driver oscillation of e-Pi-i resonance imaging of multi-phase superimposed frequency interference positioning Image condensation and probability distribution.., the big Quantum Computation in the sky, appears to look like an explosion, but so does a Radio TV transmission when AM-FM sound is used to modulate EM circuits, ..circuits that are naturally embedded functions of the Observable Universe. We can never know what is on the other side of a Black Hole Singularity unless there's a specific case of lensing. (Compelled to imagine something like that happens in the LHC) We are made of, substantiated by, ..a standing wave positioning of time duration timing rates, that are integrated by/as recirculating modulated pulses of Superspin mass-momentum, "materially", here-now-forever.

The reason for CP violation is the simulation code computes the interaction of normal matter first.

isnt there a bias built into the LHC data?

98% of that went straight over my head

Because it's that matters

How do we know that those galaxies “accelerating” away from us are not antimatter? Maybe matter and antimatter have a gravimetric repulsion, causing the universe to push outward against itself, instead of annihilating on itself.

i thought that Energy couldnt be created nor destroyed so even a larger Universe would contain the same overall energy that a smaller universe contained.

If there is a difference between matter and anti-matter can it really be called anti-matter?

There is a parallel antimatter universe with a little kernel of matter... and perhaps it mirrors our universe. ???

Yeah, why?

Maybe a lot of the antimatter was somehow transferred to a kind of alternate universe?

Matter is a physical perception and anti matter is a non physical anti perception and IMHO must be equal for any amount of one or the other to exist.

Does it realy matter...?

In the past universe anti-matter and matter looked the same, so it's an assumption that the universe is like the matter of earth

Does dark matter have a anti dark matter?

Good video , even better because the usual BS was missing. Also a very pleasant speaking voice.

Does it all really matter...? ... or should I say... Does it all really antimatter...?

The same reason why there is less human with rh- blood than rh+ blood type

How is Academia cool with the notion of "antimatter" but foam in their mouth when talking about the Aether?

Did she just say there's antimatter in my banana?? Wtf mind blown

There isn't, we have equal amounts of both. Our convention is wrong, the main difference between matter and antimatter is charge, so why not add charge to the definition. Positive charged particles are matter, negatively charged particles are antimatter. You have equal amounts of both, and symmetry can only be violated locally depending on which you have most. We don't need dark energy to explain our Universe.

Could antimatter have gone backwards in time at the instant of the big bang?

Because it matters.

Glad to have an opportunity to voice my two cents on this. Why do you think there was some bias as to matter verse antimatter? Seems arrogant. Why not instead while all the forces were still in Unitary mode +& - be subject to the same effects as the proton and the electron? At least temporarily. Too much to wrap your noodle around?

Luv your guts, Tara - even your anti-guts.

study study study!

... Does it matter?

Well I heard it might be with the very problematic weak force that violates Parities

Last I heard, the Catholic Church was being investigated for CP violation... maybe physicists should try looking there?

Chance

It is not ! ! ! Your body consists from the same number of the negative electrons as the positive positrons. For a 83.6[kg] man it is aproximately 1x10^29 electrons and 1x10^29 positrons. With the mean mass equal to m(proton)/4 for each. The half of you is matter, the half of your is antimatter. The mass of matter is practically equal to the mass of antimatter. The number of negative elementary charges equals the number of positive elementary charges. You are practically neutral. However not absolutely. On the level of the elementary particle, the electrons and positrons, there is perfect charge as well as mass parity. In their pair creation from massless gamma photon (with the energy larger than 2.022 MeV) as well as in mutual annihilation of electron and positron, creating twin of photons, catapulted in oposite. And again without the mass and without the charge. Still, keeping the energy of the maternal electron/positron twin preserved. Collosal matter/antimatter disbalance is just only on the level of lego composition of proton [e'+, e'- e'+] and antiproton [e'-,e'+,e'-]. And all the higher hiecharchies (atoms, molecules, ...). Not in its roots. On the level of electrons and positrons. For more, see ResearchGate (e.g. "World of the rings", ..etc.)

Presuming that an anti-mater civilization that knows about anti-mater exists, are we made of mater or anti-mater?

Anyone planning a banana drive for interstellar travel... ??

Nice theory of a theory.

You want an actual theory for once instead of a fire and forget youtube comment? Here's one fer ya. Gonna be a long one though. Inflation. Matter if compressed enough forms a black hole. So, why are there no anti-matter black holes? Since anti-matter is the reverse of normal matter, it stands to reason that a white hole, the opposite of a black hole, also does the reverse of black holes: Black holes swallow matter, White holes spew matter. Or to put it in another way; Light cannot Escape Black holes, thats why we call them black holes. Light cannot Enter White holes, thats why they appear white because all light coming from all directions cannot reach it's core so it just compresses around the edge as more and more light catches up to the event horizon. White holes already exist in theory so this is nothing new. But here comes the realization: White holes are made of Anti-matter. And that is why we haven't found any, even though they're supposed to exist. Here's the rub: Black holes swallow space so fast that light cannot escape it, because space is falling inwards faster then light can travel through it outwards. Therefor, white holes must make space so fast that when light tries to approach it, it's simply kept at bay because space is being made *faster then light*. And there is exactly 1 theory we know, which still isn't explained, which explains the uniformity of our universe; The Theory of Inflation, or that space expanded rapidly faster then light which explains why our universe is uniform throughout. It's not that there is more matter then anti-matter. There *was* *more* anti-matter then matter. That's why space was created faster then it was swallowed. After all if compressed matter makes black holes why didn't the big bang IMMEDIANTLY collapse into itself? A counterpart that drove it apart. As to why that process stopped at some point: Black holes radiate away their existance through hawking radiation over time. So, similarly, White holes would need a "source of fuel" too or they would collapse. Since Black holes increase their mass by absorbing matter, it stands to reason white holes increase their mass by absorbing anti-matter. Since anti matter behaves in an opposite manner, more mass would infact mean more anti-mass, therefor a bigger sphere of space repelling or even creating material. The white holes just absorbed anti-matter faster and turned it into space faster then black holes could absorb matter. That imbalance lead to the white holes winning the mass race and Inflation happening. Ever increasing sizes of holes means ever increasing amounts of fuel consumption. As the White ones where bigger they burned out faster; leaving no Anti-matter for Matter to annihialate with thus leaving... our universe as is. The white holes functioned as a secondary source for anti-matter consumption (outside of annihialation) which burned faster then the secondary source of matter consumption (the black holes). Which as shown explains both the question of the video AND the theory of inflation. As to why THAT all happened.... pfft i don't know. Probably an uneven energy distribution in the first nano seconds of the big bang. Same reason why our solar system isn't populated with equally spaced and sized planets becuase the supernova that created the gascloud of our system didn't explode equally everywhere either. If you start with more energy in one place then another you're gonna end up with clumps. And the white clump was just a bit bigger then the black one i suppose. If you want a quote for that last bit: God is just a lousy cook. Think we can atleast all agree on that.

My 50BMG is an antimatter(ial) rifle

Title it "how antimatter matters"

One word. God.

Your Beautiful.

What if the regular matter is the anti matter and that's why we cant observe dark matter?

They all went to the anti universe

Anti matter was beat silly and went all Dark Matter on us.

Incorrect I’m afraid. Run the clock back just a Planck length ;)

The Big Banfg created subparticles .... not atoms. it is possible that none of these particles had any rotation, therefore no gravitational forces.

Cause there is?

There probably is the same amount. just a massive explosion from the annihilation at the beginning and blew us apart, then eventually there was a enough empty space between us that the universe could expand faster than gravity could accelerate us back together.

0:58 actually we don't, we think the universe started off as photons (pure energy) which then, under pair production, produced particles and antiparticles. if you instead say that equal amounts of matter and antimatter were created at the moment of the big bang and then ask why there is more matter, the typical response is that maybe the underlying assumption is false, meaning that maybe the universe didn't create both matter and antimatter equally. saying that the universe started out as photons (the simplest particle) makes the most sense and that theory at least gives you a natural process to investigate

Did I hear this right? There is generated antimatter in bananas? Wow! Now I know how to loose weight.

No comment.

Send me truck loads af flambéing grant money for the answers to this and more.

So many armchair fanfiction physicists in chat

"anti-matter" is the last remnants of energy...it's the Post-Modern of Physics

The universe presumably branches (and rejoins) like a family tree, and so the antimatter is likely just way on the other side of the universe, where we simply can't see.

But we dont know if antimatter exists, just a thought

Becouse you are the child.

Cause Jesus!

But how is antimatter real if the Earth is flat?

There is more antimatter in universe than matter. In fact, we're all made out of antimatter. We've just named the two wrong.

Are you talking about matter in the known 5% of the universe or the unknown 95%?. All conjecture in my mind, about time we stopped pretending we know more than we do isn't it?

Because Yahweh created by a pulse of light, and then from nothing comes nothing, how nothing can create something ? GOD 👍
