Space Time explores the outer reaches of space, the craziness of astrophysics, the possibilities of sci-fi, and anything else you can think of beyond Planet Earth with our astrophysicist host: Matthew O’Dowd.
Episodes released every Wednesday afternoon!
Matt O'Dowd spends his time studying the universe, especially really far-away things like quasars, super-massive black holes, and evolving galaxies. He uses telescopes in space to do it. Matt completed his Ph.D. at NASA's Space Telescope Science Institute, followed by work at the University of Melbourne and Columbia University. He's now a professor at the City University of New York's Lehman College and an Associate at the American Museum of Natural History's Hayden Planetarium.
Previous host Gabe Perez-Giz is an astrophysicist who studies black hole physics. He received his Ph.D. from Columbia University and also hosted PBS Infinite Series.

    So, quantum loops are not actually loops, but math that defines space in ways that mathematically resemble loops? ...and those "loops" are more like definitions which are describing the actions(?) or vibrations of the states of the quantum foam, which is how space is organized?

    The one question I wanted answered was why the trapped modes don't add to a black hole's mass. Or, using the hack explanation, why when the event horizon splits mass/negative mass pairs does the black hole always seem to eat the negative mass half? Shouldn't that balance?

    Expansion is the normal state of gravity free, negatively charged, electron scalar fields that collide along their perimeters to create spin (electromagnitism) and fusion of electrons into quarks & gluons. These collisions create a thermodynamic vortex of matter with a black hole at it's core, known as a galaxy. Gravity is the flow of electrons attracted by the quarks in protons and photons are the entropy of a gravity field.

    Quantum physics is the study of the very small. The meaning of an opinion is the in a way a principle of the very small. What I'm saying is that an opinion of another person is not relevant for "you" only if you want to collapse your opinion to someone else's opinion. Just a thought that i had a couple of days ago.

    I'm glad its gonna be about the quantum multiverse. It seems to me that the wavefunction is a superposition of different universe-reality-timelines that interfere with each other and that the collapse is only a loss of this interference as each timeline plays out differently, over time different probabilities may play out with regard to a "particle" and these differences may add up. So the apparent difference between the quantum world and the classical is about the same sort of statistical phenomena you get from throwing a die many times and plotting the results, giving you a different perspective on the same thing. Don't a lot of interpretations fail to account for this branching of reality and have problems imagining ourselves to not just exist on one isolated universe-reality-timeline?

    quantum mechanics says that a particle can be at two places at once. if we can say that a black hole's singularity is not something with no volume but something with infinitely small volume. there's a difference right? so we can say all the black holes in the universe are the same but forming in different points of space time. everything that goes into a black hole just falls through the hole and goes to place outside the universe which is not even a place but the object is all that there is over there. this means that information is also not destroyed. this could also be regarded as the black holes mass, entropy and hawking radiation could b from this.just a thought i had in school yesterday.

    We always have to re answer the same things because people lacking education recycle the same old stuff Not even really as questions 1. There must be a design. 2. There must be a reason 3. There is a purpose in the design 4. We are the "top of the chain" hence the above statements are valid. It is in the end the same experiment we can ask without going into quatum mechanics If a tree falls down somewhere in the universe and the conditions are right for it to make noise. Do i need to be there for the noise to happen? When the questions try and bring us back as the center of the universe because that is what religions falsely still states as absolut, Then we already know that the entire angle is wrong Lets move on

    Matthew why did you have to present the *collapse* idea as a valid theory again? You could just have pointed out that no collapse is ever needed, when Wigner, his friend, his family, and any other obsever is always in a superposition (and all absolute facts and conclusions in their heads are also superpositions). Presumably you save this explanation for the next video? But anyhow, you now do what the popular press is doing: promote the mysticism of the old QM, with its collapse! (Sorry, but since Albert's not here I had to remind you..)

    so what would happen if the sun was to flip it's magnetic poles. Would that not have any effect on the earth? Since the earth is on cosmic journey through space, being dragged by the sun. Essentially, the earth revolves around the sun due to magnetic attraction between the celestial bodies. Also, if it has nothing to do with bit, then what would you say is stoping the earth from just going off on it's merry way away from the sun and fellow planets? This since we already suspect the sun is going through a magnetic pole reversal.

    Around 6:40 they're making a point that a neutrino must have mass because it can't travel at the speed of light. And thus experiences time. So photons have no experience of time. But what about when they slow down? Does this mean a photon might have some mass? Or that it can acquire mass after interacting with a field that causes it to lose velocity?

    Is wavefunction collapse really needed to interpret quantum phisics? Maybe the wavefunction is the actual phisical reality and the clearly defined world what we see around us is just a perceived thing. Isn't there a way to formulate it that avoids the collapse totally? That would save us a lot of metaphisical debate.

    7:58 Why was it weird that the wave equation of a Graviton was found when length was considered on another dimension? What if the length these strings are tightly related to gravity? They would be interacting at close to speed of light, and with the energy of the strong force why can't we have gravity appear by making it harder for them to talk to each other further away? Could it be reason why they are so tightly together in the first place? Must be a ridiculous amount of gravity required to rip apart a strong force.

    I was thinking if we can create a technology where we can encapsulate a starship within a beam of light, then shoot this beam of light at the nearest star Alpha Centauri @ 4.367 light years from Earth, we can achieve a velocity of 100% light speed and reach it in 4.367 years. Of course we have to de-capsulate/decelerate the starship before reaching the destination at a safe distance. I call this the Particle Photon Encapsulation (PPE) Drive - a starship (particle) contained within a stream of Photons and riding it like data in optical fibre at the speed of light to the nearest star. This of course would be a one way trip because we need a powerful light cannon to lauch the ship to the destination. However, if we can make the starship generate it's own beam of light in the direction of travel and then encapsulate itself into that beam, then we can do away with a launch pad and the starship can travel freely. The starship is made out of particles (matter) and light is made out of photons (energy), so this kind of technology has to be able to encapsulate matter within energy - the reverse of the natural phenomena where energy is encapsulated (contained) within matter.

    The snow melts before the end of winter even. Then it is not cold enough for snow again for 8 months at least. People grow crops at 60 deg. north. How is a slight cooling going to see snow last through the summer? 6 feet of snow melts in a few weeks with freezing nights and days at +3 to +10.

    Not to assume that I'm smarter than a Princeton professor of quantum mechanics, but the idea that our friend's brain is in quantum superposition, rather than a single electron on the detector array becomes stochastically available for excitement by a finite quanta of electron wave energy... it just seems unnecessarily solipsistic to go with the consciousness thing. Whatever the real answer is, it's probably not magic.

    "Our physical world is made of objects not quantum probability clouds" Uhhh, beg to differ. Because I mean... isn't it though? It's just that the more massive a quantum object is (like say, an atom, or a buckeyball, or a strand of DNA, or a human body, or a planet), the smaller the wavelength, reducing the probability of positions to a more finite region of spacetime... right?

    Has anyone attempted to run experiments around consciousness and wave-particle duality? For example, have a computer record the results of a photon detector (left or right), but destroy the data in an irretrievable way so that a human observer (conscious entity) could never tell which slit the particle went through? If wave patterns still form, perhaps consciousness is more important than we posit. If no wave patterns, then we know that detection without consciousness causes the collapse. Etc. etc.

    This guy (mngos.info/video/qbDYqHyelsySZaw.html) "proved" in this video that bells inequality wasn't actually violated and that the problem is only on the inefficiency of the experiment in detecting the photons. What would mean that hidden variable is possible. Can you disprove him? I confess, even being a physicist, that I can't. I may be missing something, as might him. It would be interesting if you comment on it.

    Hi Matt, your video is actually wrong because Conor Mcgregor proved you can bring your dreams into reality if you focus hard enough

    On last thing: At the end of the video where you explained both the observer and their friend observing the result at the same time, a very hasty conclusion was made. Only two choices were listed: Either you and the friend experience the same result, either you must conclude your friend is made up by your imagination. There's actually a third possibility... and it will make people's heads spin, I know it did mine: Both you and your friend experience different conscious realities, which includes different versions of one another. This is a very bizarre thought but one I've gotten used to: That when you talk to another person, you may perceive a newly branched version of them each time, while their consciousness may be perceiving a different version of you doing something else at that moment.

    It's sad to see even an objective science channel struggling not to reject a very valid theory due to materialistic culture. The video didn't even mention Dean Radin, who has repeatedly confirmed that meditators are capable of influencing a double-slit device from a distance and even posted graphs showing consciousness influencing the probability... all because materialist scientists pretended to try the experiment without training their minds or even keeping them open, get no results, then go like "it won't work for us and surely it's not our fault so it must be fake because mysticism lol". I for one have no doubt that yes, consciousness collapses the wave function. Or rather sub-consciousness... obviously there's a reason why we can't influence reality directly with our minds, or rather only can on very tiny scales with an extreme amount of effort. I've done a lot of thinking on this in the past, and there are inexplicable paradoxes to the absurd idea that consciousness is just atoms generated by the brain. If anyone's interested I might dive into those arguments, although last time I tried to the response was along the lines of "you must be wrong and there has to be some materialistic explanation even if none of us can find it".

    Strange that every time dark matter is looked for its not there. It would be really nice to actually have proof of the mythical dark matter

    It's interesting to note that humans think of the alleged simulation as something that obeys the same rules and principle our universe does.

    As a classics major, I would have to go with a hard c in Principia. As for the chimps and monkeys, I'm less concerned about that than about why our ancestors weren't either australosimia or notopithecines...

    If a consciousness observing something does not actually create reality, then they should not have used the word "observer" in so many parts of the science. Other than the idea that the observation and the collapse are not dependent on the conscious observer, you could also theorize that human consciousness itself is just what is required for the wave function to collapse, but that doesn't mean that the observer personally makes it happen on purpose.

    It's on watching all of this that I want to go back to believing pilot wave theory explains it all... I'll have to watch those vids again to remind myself why not. I hope I'm convinced - mysticism is so inconvenient for my state of mind!

    From a physiological point of view wouldn't this imply there is no collapse and it is merely a delusion of a limited mind & sensory receptors?
