this is like discovering Gold ! Professor Carroll thankyou.

[@HarryNicNicholas]

great stuff dumbed down just the right amount for a guy who does finger painting.

[@fieryweasel]

This is a great lecture. I've watched him give it in several different places and it's always a good talk.

[@Jgill99911]

love sean carroll the way he explains everything makes science even more fascinating 🤯

[@sebastronomical]

Awesome share thank you

[@newolderalso2]

Superb exposition, again, by Prof. Carroll, thanks for sharing.

[@stella_7mccarty649]

You are very clever with your mind and so much touched with the practice. You can see of all duality in the glob - is incredible ENERGY and will be so much innovation in the future. Will be no sickness and pain anymore and just so much joy and excitement- everything will be vacuumed up with the black hole naturally. We can’t control the universe, universe is controlling us. And is so important to understand how important you’re for the future of the universe.

Many thanks for an excellent lecture. I don’t know whether anyone felt as I do but, for me, this really picked up at my level and took me on very nicely.

[@Iamthepossum]

Many thanks to you for taking the time to upload this to share with us. 🙏🏻 This dude is so fab, I truly adore all of his talks ❤️ Although he gives the same presentations again and again for his public audiences, his content is never tiring as he always imbues it with new color and dimensionality each time. SC is a truly great professor & seems to be a fabulous, caring human being with so much sincerity and concern for educating the common man.

[@tonibat59]

Glad to hear that he would 'still' hire Einstein if he was here around... Tks great lecture

[@JungleJargon]

At the singularity there’s infinite density which has enough gravity to account for gravitational lensing when combined with the known amount of matter and mass of the galaxy. There’s no need for invisible matter. It’s all there in and around the singularity. What’s not being taken into consideration is the variable of the measures of time and distance the farther away from a singularity it is. It is actually changing the speed of light from place to place. The speed of light is faster in the outer edges than it is near the center causing the lens effect just like a glass lens that slows down light near the center and allows for light to travel faster in the outer edges.

58:27 Small historical mistake: Schwarzschild presented a particular solution to Einstein's field equations not a couple of YEARS later, but roughly 1 MONTH later...

Consider the notion that the universe might not permit true infinite parallels. Within the intricate fabric of space-time, the idea arises that even parallel paths could converge or diverge due to the inherent complexity and limitations, challenging the notion of endless parallels in our understanding of the cosmos. Exploring such limitations could open up new avenues for comprehending the fundamental nature of the universe.

[@wildtype5556]

When you look up Einstein’s field equation, you see 8piG divided by c^4. And that is then multiplied by T mu nu. Why is that c^4 term not shown in this equation?

[@jonathanbaincosmologyvideo3868]

The bit on Newton was good... The rest of this video defines the very concept of the Expletive. 'From an accredited US healthcare educator', nogal, Did they also square-root the negative somewhere that I skipped over?

If the rate of subjective time reaches zero at an event horizon, does that mean you would see the entire future of the universe elapse behind you if you fell in?

two objects of different mass fall at the same speed but with different force. the force changes. gravity is not a force.

Gravity is not a force, but even physicists call it a force when to do so is convenient, as here.

[@billblais3580]

I’m not qualified to follow up on my concept... Who Can ponder this concept? "Exploring the concept of a non-linear curvature of the space-time plane with elements of quantum entanglement, could investigating the role of entanglement or other factors potentially shed light on perplexing variables in current physics and mathematical calculations? 1:33:03 Is there merit in considering these unconventional ideas for a deeper understanding of fundamental forces?" Think of it like going below zero in this context and how it flips??? Now flip with entanglement.

[@jamesonrichards5105]

This is footage from 1,000 AD right because there is no other way the mic can be this bad

[@billblais3580]

What if the shape of the plane that space time exists upon was non-contiguous? Non-linear? Imagine viewing the largest fields as a quantum entangled (translucency?) shape ? I may not have a correct yet?… I’m trying to imagine looking from the inside of a tiniest quantum element outward as I were pointing a flashlight out… At the same time, needing to know the point of entanglement, that would converge all of my calculations. Am I proposing that there’s a possibility of an equal concurrent force on the shape as a force? The entangled shape would flip the switch on everything the same way that switching from positive to negative numbers would change Jim Matric numbers/forces/effects? I’m no scientist. No mathematician. Simply an artistic thinker. Is there any reason not to ponder my thought as a new perspective on solving the equations?

[@billblais3580]

Perhaps space time is not as similar to light as often presumed?

[@AhmadAwan-ku7mg]

Sean Carroll is the best physics teacher

[@atticuswalker8970]

how do you explain the difference in force of two objects falling at the same speed. if gravity is a equal force. the difference in mass under equal force should react differently in motion not just their difference in increasing force. but if gravity was the path of least resistance . the result would be as observed.

[@Zhavlan]

Light is an ordered vibration of gravitational quanta. This is determined experimentally using a hybrid fiber optic gyroscope (based on Michelson's experiment 1881-2015).

After studying gauss,Tesla faraday, I feel like there’s a technological gap of time that could have occurred, either didn’t or we aren’t being told history from a fair perspective, at least for me a westerner in the United States, we are not taught these facts in history class, we are taught that the 1800’s was only about race war. Almost everything we take for granted in our daily lives today is thankful to these gentlemen and Sean.

quoi?

[@misewixe2777]

Apart from the electrical advancements throughout ALL civilisations in history and the many cover ups thereof. I too think there is huge time delay or lag that will catch up like a massive wave or burst, but sure. I think it's due to using electricity by 'forcing' too much power out of the current. The energy released isn't flowing back naturally. What I'm saying is - you can't expect having a balanced system by taking a too large portion out at once in a short period of time. If we want to harness good clean and sufficient energy - we should piggy-back on earth's ecosystem in harmony, instead of crowbaring our way through for gains, like machetes in a jungle. Go with flow always applies. In this case.. Amplitudes were far too high and there is the time lag... Might be cause electrical technology has been scaled down another level. And looking back in history - that's when multimillenia empires 'seem to vanish:..

I send a level of altruism in his statements and volume. Like there was a line up for people to do the presentation. Everyone else stepped back while he stood there. So he gets to say "hey world, check this out!" And hopes no one throws rocks. Poetic since the earth is prancing around the sun waiting for the next cool new scar.

[@helifynoe9930]

And, if you use my version of space-time geometry, which is composed of both motion vectors and length scalars that are linked together, you can use it to derive the special relativity equations and the Lorentz transformation equations, and complete this task in mere minutes.

[@bigrigexperience9294]

Once you indulge into Einstein's maniacal ideas, you lose credibility. The fourth dimension -c dt lacks any plausibility because time related to material events, not to dimension. Newton's second law F= m.a already accounted for acceleration which is spacetime variable. Nobody could use or benefit from Einstein's relativity, special or general. Lorentz Transformation accounted for the kinetics of constant c, variable v. Because Einstein's relativity lacked causation, relied on Euclidean geometry it must not apply to time because time is eventual, originated from material thermodynamics, not Euclidean geometry.

[@sobeeaton5693]

Newtonian physics works, in the sense that it allows you to calculate some quantities in a useful way, but the metaphysics is completely impossible. How is it that a rock flying through empty space can recalculate its own momentum to arbitrary precision in zero time?

[@bigrigexperience9294]

@@sobeeaton5693 Classical mechanics was founded on empirical observations based on sensible collected data about celestial motion. The singularities issue concerned hypothesis that were never encountered in practice. For example, one cannot assume that gravity at the center of Earth is infinite by putting r =0 in Newton's law of gravitation. In the case of Einstein's relativity, you would be mocked by any practical physicist if you think that Einstein was a capable scientist. Einstein squandered his life in delusion that attracted detached theorists. Back to your puzzle of memory of momentum and inertia in remote space. You would not solve that puzzle by relying on relativity. You can only solve that puzzle either by inertial gyroscope or statistical gyroscope using memory flash storage. Here is why no one believed on trusted Einstein to solve any realistic puzzle. Gravity is generated around and in proximity of a star or a planet. That means far away from that star or that planet, you got no gravity. So, how do you curve spacetime when and where gravity of one star or one planet has no effect. The reason why you cannot sell Einstein relativity to a numerical analyst is the time variable. Einstein delved into spacetime delusion without accounting for the event that initiate time or the location that surrounded events. By metaphysics, oh my God, that is not where science ends. That is were delusion thrives.
