Seth Lloyd - Why is Quantum Gravity So Significant?
Quantum theory explains how particles and fields work. General relativity, discovered by Einstein, explains how gravity generates the structure of the universe. But the two great theories of physics and cosmology are not compatible. But this is impossible because both describe reality. Only a solution to quantum gravity can solve the huge problem.

I don't know if someone can explain quantum gravity, but if you want to understand the hull concept, I will recommend you the new book - "Theory of Everything in Physics and The Universe"
There was no mention of gravity. Perhaps the name was meant to be “why is quantum computing so significant”?

Don't let yourself get entangled in a bad situation.
Other than just shaving it all off, there are two hairstyles used by balding guys. The first is the COMBOVER and is by far the more common. It’s used by guys who don’t like that they are going bald, and in a futile attempt to slow down time they let parts of their remaining hair grow and use it to try to hide their increasingly hairless scalp. But the second is the much rarer WHOGIVESASHIT and is demonstrated here perfectly by Seth Lloyd. It’s used by guys who have neither the time nor the inclination to bother about what anyone else thinks. It involves just letting the stuff grow freely and flap about like a just-caught mackerel on the boat deck. Props to these guys.

I guess I missed the part where they discuss the importance of quantum gravity.
The problem is that people and things pop in and out of reality throughout our lives, and everything at a distance we thought was linear, isn’t. And that attacks people’s assumptions with causality. Once you remove the assumptions we make, quantum mechanics just starts to make sense. And here’s a news flash. Once it makes sense, it starts to be more evident to the individual observer.

Could quantum wave energy information flip into classic particle matter information through gravity? If so, how might quantum gravity transition wave energy to particle matter?
Please add subtitle
Manifolds belong to the branches of mathematics of topology and differential geometry. The main idea here is that even though our real-world data is high-dimensional, there is actually some lower-dimensional representation.The underlying idea is that manifolds are like curves and surfaces, except, perhaps, that they might be of higher dimension. Every manifold comes with a specific nonnegative integer called its dimension, which is, roughly speaking, the number of independent numbers (or “parameters”) needed to specify a point.
This guy is well beyond my capacity to understand him but the title of this video is misleading. Seth Lloyd never talked about quantum gravity. Anyway the subject of quantum computing is fascinating. It's like trying to understand consciousness.
Really cool guy!
Their conversation is good, BUT: 1) this video is mistitled, as many here have pointed out, and 2) the date on the video (May 2, 2021) makes it look like it's current, but it's clear that this was recorded years ago, since general purpose gate-based quantum computer have advanced into the 50 - 125 physical qubit range.

Now the question is that .....which and what is our true reality? Is it the dark external material world reality we observe or the subjective things (which includes our Intelligent and emotional assessments and appreciations) that appear in our consciously living mind(,or perceive /experience by)? Apperantly each is representing the same information at two different levels. If we can't define our true reality... How are we going to grasp and understand the real world? To know it we should know what the Maker the universe says about His creations!
Gravity is a thermodynamic macro scale emergent phenomenon. Why are these people still confused about bringing together qm and gr. Everything is operating in the same field. The perturbations at the micro scale just sum up to a gr style field at the macro scale. There is no such thing are separate domains. Everything derives some from same thing
This video wasn't about quantum gravity--it was about quantum computers.
Maybe quantum gravity the action of one wave energy on another wave energy?
That guys hair is in a superposition
Yeah, not convinced Seth. The reason I think we don't have a good intuition about quantum mechanics is because we haven't developed ways of thinking about quantum mechanics in a way that intuition can connect with it. Richard Feynman took us one step towards a more intuitive understanding with his Feynman diagrams, but this is pretty much all we have gotten. I suggest stop celebrating and marvelling at how unintuitive QM is and develop more intuitive ways of thinking about QM.
Title needs to be changed - this is not about quantum gravity
Asking someone about gravity that uses current theories will have no answer. You can only ask someone that doesn't follow the Lambda-CDM model like me. In my theory, the universe already existed when the big bang happened. Our universe turned itself into a gargantuan particle collider like CERN. Space is made of matter or it wouldn't be absolute zero. Dark matter is extremely pressurized electron neutrinos that go through matter at will. Heat from a mass creates these particles by destroying electrons and turning them into electron neutrinos. These particles are energized dark matter which doesn't react with normal matter at all. Space catches these particles since they are all the same. The natural pressure of space pushes through the outgoing matter and these unenergized particles do react with normal matter as gravity. At absolute zero, it all stops.
All this really increases the chances that reality is some kind of technology/simulation/computation
Quantum Gravity is a misnomer. The force of Gravity is derived from Einstein's General Relativity and field equations. Gravity lives in the world of macro physics not QM. Who says there is a force of Gravity in QM? Furthermore, if we describe gravity just in terms of curved space-time, then QM which appears to operate in Backward Time only, cannot be subject to Gravity in the way we understand it.

We don't see gravity and believe it's there, cause the effects it has on objects. So why is it so hard for people to believe in an unseen God, that can be observed through objects?
Seriously, I was investigating quantum computers in the 90's. The 1D q-bit ion-trap lattices, specifically like how do they get away with cross-coupling so completely, that was a big puzzle to me back then. Now it seems gravity focuses super-nicely nicely in the cold, so nice it looks like it might even recover a new universe from deep heat death one day. Not only that, but it should explain entanglement and looks extremely promising for explaining fundamental aspects of consciousness, but building entanglement links and quantum computers are essentially engineering challenges, so much more so than anything else that there is no comparison. General relativity wasn't needed to build and calibrate the GPS either. Personality cultism in science is particularly pathetic and depressing. And with that I've hit on another key research concept - the trope value to excessively wealthy people of relentlessly depressing others in plausibly deniable ways while pretending to save the world from itself.
