What problems might a theory of Quantum Gravity actually solve?

I've figured out how to change the stars by stopping hurricanes. Don't worry, I've technically already done the easy part and changed the stars. My parents were teachers and for almost 2 decades, they taught their students my constellation. Those kids will teach their kids. So on and so on. See, stars changed. I just need help to make it legit and with the rest. We need to get to Willie Nelson's house ASAP. No, I'm not kidding. Yes, I'm serious. I get 7 things and remember, crazy is a compliment. Will you please help?

@Jose Moises Ramos Gomez “which concept in quantum physics are you most intrigued by?” “Thank you”

I have a hard time accepting quantum tunneling

Super-position makes my brain explode 🤯 … but in a good way.

his high concentrations of melanin makes him more intelligent and closer to the origins of mankind

Well if they had the same level of knowledge as the professor, his job would be redundant

Exactly!!! 😄😄😄 In fact, when/if i come across some scientific material/discussion that hasn't been demystified well to me, i search for Neil's work or thoughts on the same subject on the internet knowing that he will make matters easy for me.

Your book astrophysics for people in a hurry just arrived and I’m loving it Neil!!! Do you have any advice on other amazing books either from urself or others. Became a huge fan

quantum tunneling

Anyone who relies on "what they were taught in school" is likely too dumb to be worth the trouble. "Graduate" doesn't mean you're done. It means you have gone to the next level of self-education.

Well your school didn’t even succeed in teaching you to spell simple words… how would you expect them to teach you quantum physics?

@@MaddenDoctor because my phone autocorrected in to is?

I actually thought that was one of the worst explanations in this video, the variation on the celebrity at a party analogy. The image is like, average Joe walks through the party without slowing down (which is ironically a better analogy to inertia) while the celebrity gets mobbed by fans and slows down, and that’s just not a very good picture of how the Higgs field works. Instead, think of it like this: the Higgs field is the population, mass is the measure of your celebrity, and the greater your celebrity the more people from the population get assigned to your entourage by the Higgs mechanism. Now think about people with different celebrity trying to get into a party. The greater the celebrity (energy), the larger the entourage (mass), the less the bouncer will be able to slow you down on the way into the party (inertia). Cuz if we’re going to talk about parties and celebrities, I think that’s a much better way to understand mass, the Higgs mechanism, and inertia.

Glad the explanation was helpful!

@@altortugas5979, thank you! Even better! Much appreciated!

The Higgs mechanism uses a sorta infinite uncertainty. It's wild. Have you seen Susskind's lecture on it?

Ah, I am very well acquainted with the pity-particle

That makes 2 of us

Lol

oop

Here is 1 for ya. What is alive? Being conscious of one’s existence or the energy a particle absorbs or retracts. Real q. 12:43 in. In a man with no legs. Encounters ants feeding. Who wins. Now if said man encounters an ant pile and cannot escape. A single organisms can accumulate mass and consume on a hive mind mentality. Now if said man was covered in toxic chemicals that killed the hive mind how manny would die before the positional awareness of the organism be calibrated. This is the basic experiment I got from ya so far. Also. My Leo theory. Which is that some particles are so small and so fast that we cannot quantify them. How ever their impact is seen throughout the universe. Take a wave length and a particle traveling through. Now in a infinite space and self propelled energy. A particle can manipulate the obstacle in a invariable route of known positional reappearance.

Like Schrodinger's cat... Would StarTalk have uploaded this video, if you had not watched the video about the Higgs Boson earlier today???

Had the same happen but for quantum physics lol

This episode is new but the content is not. They had made that one before.

the Higgs Boson is NOT related to our mass. Its field is the culprit. The boson is just a spot with a lot of energy in one spot in the field is manifesting as a particle. It's the interaction particles have with the field that grants mass. also, related, EM waves do not interact with Higgs field, that's why they're massless

@@vansdan. So, the Higgs Boson is not actually a particle, it's an energy field acting like a particle?

As a 31 yr old, I'm so sorry that was your experience 😔mine were amazing and fostered environments of curiosity that left me wanting to learn more. My physics teacher in high school for example basically related everything to ancient War machines (trebuchet, catapults, etc) and drag racing. My biology teachers took us on great field trips to see the biology we learned in action. I get excited thinking about those days as a teaching assistant now doing my best to make learning engaging and fun for the students I have as I want them to remain hungry so to speak and to seek to understand the world around them.

Okay jimmy

Rip jimmy neutron

Thanks for your comment!

So glad to hear it!

Keenan Browne, if just a little punctuation is beyond your grasp, I think quantum physics may prove an insurmountable challenge.

@@scottmatthews1039 you got me I was getting lazy on dictate had my phone write it all for me and therefore that is why you found no punctuations I am dictating this message to you as well it’s the laziness of the future you’ll see more people not using punctuations or you’ll see dictate get better

Amazing chemistry!

Thank you, same to you!

@@StarTalk I'm a huge fan of you and science as a whole. I really appreciate and respect what you do and I would love to get some books on quantum physics and astrophysics soon. Any suggestions for good reads?

I'm no scientist, but this is what I think. Information cannot travel faster then the speed of light, but since the wave function of that very particle already exists on the other side of that "hill" (or any other body of mass if you will), information does not travel faster then the speed of light. That's why I think the electron makes the jump instantaneously.

It’s like it’s been there the whole time

A part of the particle's wavefunction always existed outside the barrier. When you ask whether the particle travelled across the barrier or jumped across instantaneously, you're assuming the particle was on one side of the barrier before it was measured on the other side which isn't valid in quantum mechanics. You cannot say anything about the 'history' of the particle upon making a measurement in quantum mechanics. You can only say something about the particle at the time of measurement.

Im pretty sure it’s wave function assigns a probability for it be in many different locations and once you observe it, you disrupt its superposition of being in any one of those places and it assumes one of the positions. This occures instantaneously so you’re not making it travel faster than light you’re basically just forcing it to make a decision on where it wants to be found , that being any one of the positions that are on its wave function.

Everything is something we are still trying to figure out. All of our combined knowledge is just a tip of the iceberg of what the whole truth is. Thats why science is so fun to study or talk about. It's a never-ending puzzle.

Quarks?

Yes, a quantum particle can enter a state of superposition an indefinite amount of times after collapsing. The reason we know this is because, when we measure a specific quantum particle or entangled particles, each successive measurement will record the particle in different states. The reason this particle is able to be measured in different states despite repeated measurements is because it enters a state of superposition and then collapses again during each measurement. If a particle only collapsed one time from superposition, after which it remained indefinitely in the manifested state, you would always measure it in that same state. Think about Schrödinger's cat: once you opened the box and observed a dead cat, you could close the box again and reopen it, and you would sometimes observe an alive cat and sometimes a dead cat. It's not the case that the cat is always dead once you open the box and notice it is dead. So how does the cat vacillate from being dead and alive after repeated measurements? It is able to switch because it reenters a state of superposition between measurements. Particles, and entangled particles, are only able to change states by reentering superposition. Besides, if particles were unable to enter a state of superposition after having collapsed, by this point in time, there probably wouldn't even exist particles in superposition. Superposition is fragile, and after existing in a universe that is billions of years old, chances are low that there would still exist particles that hadn't yet collapsed. But obviously there are many particles that exist in superposition, and that's because they are able to enter that state even after collapsing.

I think a science joke at the end from Chuck is a good idea 💡

i suppose we could measure speed by taking low-resolution measurements of location at two locations far enough apart where the x uncertainty doesn't matter much Oh also! We could get speed by measuring impact momentum and dividing by mass.

But it has nothing to do with the original question

@@linkingwithnaz1295 thats the most insightful part. What is one to do, then?

@@Inquiring_Together I really don't think so. Quantum entanglement describes how measurements of physical properties of entangled particles is perfectly correlated, no matter the distance between them, and it seemingly violates general relativity on the face of it. The solutions offered are: many worlds interpretation which maintains realism and free will, superdeterminism of not just the particle but the people testing it, or alternatively that general relativity is wrong at least when it comes to the micro quantum scale. I think as that this is far more interesting implications than the quantum tunneling effect. As far as I understand, most scientists don't believe that general relativity is wrong, that leaves us with many worlds interpretation which I feel like is a very clunky solution, and superdeterminism which I think has some very alarming implications.

@@linkingwithnaz1295 ahh..turn to knowledge, I see. I was expecting as such.

I believe it might be that the C^2 is bc you need to go past the speed of light. Once that happens you gain more Mass and therefore need more Energy to maintain the speed. I could be totally wrong.

I can give you something to think about... So c is the speed of an electromagnetic wave traveling in vacuum. The generalized formula of the waves equation (d'Alemberts equation) presents (1/v^2) as the wave velocity, and it's squared because it actually describes two waves, one going forward and one coming back, each having velocity v. This has mathematical proof becuase the wave equation is a differential equation with two solutions. So you can think about the velocity being squared as the product of the velocities of each individual wave described by the equation. If we consider electromagnetic waves traveling in vaccum, the velocity v assumes the constant value c, given the proprerties of vacuum. For instance, the same electromagnetic wave, has different speed in a copper wire, but the wave equation is the same. This whole thing it's just to explain that c is just a velocity in a given medium, the highest possible velocity because there's not better medium than the vacuum. Now, let's introduce the relativistic kinetic energy K: it's true that K=E-Eo, where E=m*c^2 (energy) and Eo=mo*c^2 (resting energy). For things with little speeds (v

@@Enkryption You are wrong (no offense) but I admire your ability to try and think it trough. The math in physics tells us that you can NEVER travel past the speed of light. Also if you have ANY mass at all the mass will reach infinity as you hit the speed of light. I promise I will share the correct answer with you. (Let a few more ppl guess first. It's good to think deep.) Thanks for your reply.

@@antonioe.2396 No offense but that's obviously a cut and paste job. I think that you yourself don't actually know. If you are not able to brake it down to a layman's level in a simple explanation...then you don't know. If you actually do...I challenge you to do so. When this is all over you can read my explanation. I teach Science like Neil does...so all people can get it. Thanks anyway for your answer.

@@MegaSkills9 why do you say it's a cut and paste job? I am a uni student so I know this Man you weird, you write like you know the deepest secrets of the universe lol (no offense) chiiill

Made sense. Just annoyed by her calling it a wishing bone. Who does that. Like she'd never heard it called a wish bone before and pulled a Jill B.

Someone should warn them so they can start making excuses to miss it.

@@mikemondano3624 HAHAHAHAHA!!! I assume you mean someone should warn my kids that Thanksgiving will include a brief science lecture. What you may not have considered is that, as teenagers, they _already_ make excuses to miss _any_ major family gathering. (Frankly, I don't blame them.) However, per your suggestion, I will warn them tomorrow _and_ give them reminder warnings _between_ now and then. You just created an experiment in Behavioral Psychology. Cool!

Huh?

Noooo, we’re not teaching Scientology!

@@StarTalk Smartphone not so smart, hehe!

That is a very good question, and the short answer to it is the Bell's Inequality. You may want to watch this video: kzfaq.info/get/bejne/jrJpqrqWqtO1pqM.html
