  • In an alternative reality I have a sex life.

  • Intelligence +1

  • so why are big bodies bending time-space if it's not for their mass? are centrifugal force + accelleration time benders?

  • very nice, i quiet like the sound effects in the lecture.

  • Spectacular. Apart from the utility of it.

  • Is this the infamous Sammy who got arrested for hacking MySpace and was ordered not to touch a computer for 3 years? Lmao it all makes sense, someone who can do that, can hack more than your garage doors 😂

  • equivalence=physical illusion, inertial frame of reference = motion [all laws of motion must be applied, not laws of rest]

  • if parallel universe is true, i hope that my other self is happy.

  • So are you saying there is a different version of me that is not a useless piece of crap? Sounds impossible

  • Check out Ken Wheeler the Bald Tattooed Monkey for even more fascinating insight into all things to do with GRAVITY, MAGNETISM AND LIGHT. It'll do your head in but it's worth it ✌

  • You’re not telling us if the photon gun shoots every photon with the exact same trajectory. If every photon shot has a slightly different trajectory then it’s easy to understand the resultant wave like pattern even when shot one at a time. I’m guessing you probably have no idea if the photons shot out of your photon emitter have identical trajectories. The key to solving this whole baffling experiment comes down to particle trajectory. Science believes you can’t make something macroscopic like a tennis ball have quantum wave like properties but I believe you can. Here's how to make a macroscopic particle like a tennis ball have wave like properties like a photon in the double slit experiment and why photons “appear” to lose their wave properties when observed - it all comes down to trajectory. One water molecule cannot make a wave-of-water and a trillion-trillion water molecules cannot make a wave-of-water if all the molecules follow the same trajectory. When a 500 nm wavelength photon is emitted through a double slit (with the slit material being 1mm thick) the slit plays out as a tunnel because it is approximately 2,000 times longer than the photon's wavelength. By quantum law - an electron in its molecular orbit will have a cloud like location probability - therefore the probability of a photon being emitted from an electron's orbit at the same place twice is highly unlikely. This means when photons are emitted from a stationary atom/molecule each photon has a high probability of having their own unique trajectory. Hence, when photons are shot through the slit/tunnel in the double slit experiment each respective photon will hit, bounce, and ricochet off the inside of the slit/tunnel at a different location. This means all the photons will exit the slit/tunnel with slightly different trajectories and consequently impact the back-wall in a "wave" like pattern representative of the electron's orbital cloud. So how do we get all the photons emitted from different locations with slightly different trajectories to hit the back-wall in the same spot? Simple - we observe them. In other words the act of observing/measuring a photon doesn't necessarily collapse its intrinsic wave property but our observing/measuring device due to its fixed location will "funnel" or “shute” all the different photon trajectories into a singular common path/trajectory before they enter the slit/tunnel. And if all photons enter the slit/tunnel with identical trajectories then they should all exit with identical trajectories and impact the back-wall in the same spot. The shute/funnel consequence is the same when we place our detection device after the slit. So if we want macroscopic tennis balls to produce wave like properties we would need to set up our double slit tennis ball experiment in similar ways - and proportions - to our double slit photon experiment. A tennis ball is approximately 2.575 inches in diameter. Therefore, the board for our tennis ball slits would need to be approximately 430 feet thick (2,000 x 2.575"). We would also have to make our tennis ball shooter have a randomized cloud location like an electron’s molecular orbit. This will give the tennis balls random trajectories but because of the shooting apparatus’s electron cloud location mimicking nature - high, low and no probability trajectories will emerge and the tennis balls will eventually produce wave like patterns where the tennis balls strike the back-wall. But again, it’s not the tennis balls themselves that have the wave like properties - it’s the electron cloud like location property of the tennis ball shooter giving the tennis balls many different trajectories of high, low and no probability which along with the mathematical corralling nature of the slits produce wave like patterns.

  • 10:55 I must warn you sir, I'm pretty good at hangman.

  • Other than in Australia, most snakes and spiders are not venomous or mildly venomous. Especially spiders. I mean, 94% spider species are very mildly venomous. Same case with snakes but it's 80% non venomous or mildly venomous.

  • I always thought about this myself and how certain things will also start to happen as the universe gets older if the space in and around atoms is expanding.

  • Looking at a clock in the dentist's.

  • "Thats where you push the button again" 🤣

  • This is stupid...gravity is force. It is not energy since black holes sucks in energy. There are more than basic four forces...electromagnetism gravity the strong and weak force. It's still studied and work in

  • I'm not fat. I'm redshifting

  • Loved the video, However can you please explain in simple terms why we all feel the earth accelerating equally when its accelerating through space around our galaxy!!! so confused, help this old man understand :-)

  • 🖤

  • People who live without purpose are the scariest sort of people. They can find no true joy and only live to satisfy the animal inside. These people have destroyed societies again and again throughout history. Promoting such an idea will again lead to the destruction of our society today. For that matter, "your truth" is meaningless. Truth is eternal and not subject to the limits of the human mind.

  • So satisfying. Have you talked about the dragon curve? I’d love to hear your thoughts on that. “It’s right up your alley” -Jurassic Park reference ahoy

  • *PBS Spacetime vibes*

  • Sir, I have a question, why there is no explosion when you are making water while pressurized all gases, because Combinations of hydrogen and oxygen causes blast

  • Everything is math. Literally everything in life can be explained by or communicated through math. Math is universal, math is larger than us. The absolute essence of our existence and everything that goes with it is math. Any even, particle, wave and any being and lack there of can be explained with math. Math isnt just something you learn in school.

  • Don't forget about the huge coronal mass ejections from our huge Sun that usually miss our tiny Earth. And don't forget about the back and forth massive Birkland Currents going between the Sun and the planets and between the Sun and the galaxy.

  • I think it is the same as to say NO, we do not expand and there thing which are unknown to us to explain it therefore GOD knowns the answer to why thing are the way they are...

  • Opps bad link from PBS Space Time it being five years old. Current link

  • Is there gravity at the very center of earth ?

  • Well that almost explains why Obama bought a couple of ocean front mansions.

  • So then... How do we derive the acceleration needed to curve local space time? That would be fun to figure out.

  • How does this model account for the tides?

  • It is like when you see a car moving on a highway and want to know its exact location and velocity at the same time which is impossible. If you want to know the exact location then velocity cease to exist and vice versa.

  • Also everyone should watch this on Frames of Reference

  • Great video! Like the longer form. No to sound trite but is there an origami equivalent to knot through re particles? It can create curl, shows compression of space as way to create form.

  • Don't know if it would help or not to mention how a seaming majority of people in Physics believe Gravity is a force at the Quantum level but this idea does not apply above the Quantum level and no experiment has shown Gravity is a force at the Quantum level it just the majority of Quantum ideas require it to be a force for the math to work. I would like explanations like that of the Big Bang stop mentioning the separation of Gravity from the other Forces until it actually proved Gravity is a force again only at the Quantum Level. I would also like mentioning the fact that Gravity has a discrepancy compared to the other forces at the Quantum level as if this is a proven fact instead of speculation unprovable so far that Gravity is even a force at the Quantum level. They had hoped for proof Gravity leaking into other dimensions from the Neutron Star Merger Space/Time wave detection that would prove Gravity actually a force even if it not detectable otherwise was a force. This was a Null result no Universe wide extra dimension for Gravity to exist as a force and be drained into only the 3 plus one dimensions detected. I would like discussions and labels of the Space/Time Wave detectors be that and it not described as Gravity Waves. A ton of the confusion is the belief not proven of many scientists that Gravity is a Force at the Quantum Level bleeds into anything above the quantum level they are discussing. Physics and Astrophysics suffer from a lot of poor misleading names. Big Bang actually coined by a opponent of the theory is not a Big Bang at all no explosion involved as SpaceTime it self expanded everywhere we don't even know if there is a edge involved at all. Dark Matter for the unexplained gravitational (effect not force) anomalies it has been suggested Dark Gravity better naming but still misleading as Gravity is not a thing again. Dark Energy when we don't even know what Energy is, yes we really don't know what Energy is we only know of Energy as an effect as well even though all matter is just concentrated Energy and thus Matter is also a effect not a thing. Dark Energy is used for the unknown cause of the expansion of the universe and the speeding of that expansion. I poorly explained this feel free to blow your mind using good sources on what is energy to find out how it currently is just a math thing. Anything that explains Dark matter is considered Dark matter even if no matter is involved in solution. That smells like a funding lie almost to get money for particle research vs non particle causes. And of course anything that explains Dark Energy is Dark Energy even if the word Energy not used.

  • Time is an illusion.

  • Wide putin be like: first time?

  • not possible with your stupid theories, can’t eve explain how to enter the different realities.

  • All Phenomenon done before million of years 🤣

  • we could make exactly the same arguments about electro-magnetic forces................are they not a force also? Or do we need to refer to magnetic fields as magnetic-space curvature? Interesting because magnetism and gravity have the same force to distance math involved in their interactions. Trying to compare the effects of gravity to the curvature of the earths surface is simplistic and childish..........they are nothing alike. All we know is that gravity is relative to mass.............more mass = more gravity influence ( just as a bigger magnet, has a larger stronger magnetic field). gravity particles and gravity waves are all just made up nonsense to describe something that in reality has its closest match in electro-magnetism.

  • For years, I am waiting for a day when Facebook runs out of business.

  • What about the road trip effect? Where the return trip goes by much faster than the going-there trip, if you take the same route back, anyway. On the way out, you are focusing on getting there. You are paying careful attention to everything so you don't make a wrong turn. But it goes forever. On the way home you can relax. The route is familiar, and the time goes by much faster. So why is that? Your explanation would imply the opposite. Actually, maybe the dog bit explains this. But then why would vacations go by so fast? Seems there's more to the story.
