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.

    I subscribe to the Interuniversal Tango Theory. We're actually dancing with our sister universe. We're accelerating toward our sister & will shortly move a lot faster as whirl around the center of her gravity. The dance will end with an interuniversal kiss, a big bang, & then we'll fly apart creating a new universe.

    But... this "eraser" does not even erase anything. It's more like "not detecting" than "deleting"... and it raises some questions. 1. Does this "erasing" part serve any purpose? Wouldn't it be the same if we let the photons free (no measurement)? 2. What if the "which-way" information of each twin photon was physically saved and deleted before/after* (*isn't the order relative?) the others hit the screen? Does it collapse the wave function? If not, then: 3. What would happen if all the "which-way" information and the screen image were stored but not seen and then we deleted (or not!) "w-w" and later saw the image? The computer memory would have to be in a superposition for a while, which is so extreme that I wish for it to be true. Also: God can't be omniscient - if he knew the "which way" information, we would always see no interference pattern. Or he has a short-term memory...

    No ones has an answer. I don't care how much math you use. We have to travel to get the answers. We are too far away to see other species of intelligent life. We have to create warp drive engines to interstellar travel to discover other life. I'm gonna be positive and assume other species of intelligent life are common in the universe just like super novas, galaxies, stars and solar systems planets and moons and we are not special we are just a product of a large universal life cycle. We are proof life can happen among the stars and must realize we are not smart enough to travel trough the universe to see our proof. The frustrating part is planets and stars are so far apart, intelligent life might of evolved and been wipe out before we could catch a glimpse of proof. We are guppies in a large ocean of a universe and must be part of the typical life cycle of planets in the right conditions. We have never mapped out the universe, it would be foolish and a large waste of space if we are alone in the universe.

    Spacetime inside a black hole is so perturbed that the Brownian Motion of all the Planck space quanta is extremely disordered. After all, these quantum bits are moving around at a faster than light pace which accounts for the extraordinarily high entropy. You can make a lot of states if your velocity is greater than c.

    Interesting content but the main words used throughout are possibly,might,maybe,what if, it’s very possible. You keep saying the galaxy looks empty but we have been looking for less than a century. Basically we have no idea if life is common or not. We can’t even measure the chemical composition of exoplanets atmospheres yet so we can’t possibly say the galaxy looks empty, let alone the universe. The next 50 to 100 years will give us a better idea. I’ll get back to you then.

    If black holes contain most of the entropy in the universe, then the Planckian quantum of space gets jostled around rapidly and randomly by the torrents of the swirl of spacetime itself inside a black hole.

  22. Igor Kyriakin

    Let me think; time travelling at the speed of light is the fastest, where it might be said that time is towards zero and space- the other component of spacetime- compared to the centre of a black hole, where time is at 100% and space is at zero. my issue is- if these are the extremes of time and space, there needs to be any interim point to establish measurement. To have any interim point (like being on Earth) means that time itself is a human explanation and not the basic reality. However, if you explain time as an energy, then the past, present and future make mathematical sense in the atomic and quantum levels as well. The 4 forces in a geometry of a tetrahedron create space around it and time as a direction. That shape can be any combination of relationship. Space is only the distance between points. Another human explanation. I rest my case.

    One sure sign that we are living in a simulation is if information leaks from the future into the past. Deja-vu is the minor example where you are doing something and remember you did it before. The major example is knowing specific information ahead of time. It happens. My mother had a dream about a little girl drowning in the lake where we lived. The next morning her brother called to warn her about the kids because he had the exact same dream. The girl's mother had the dream as well. That kid was in a life jacket all the time, even when nowhere near the lake, except for the day they were getting ready to go to church and her father came to see if she went to our house. We found her body exactly where my mother saw her drown in the dream several years earlier. My brother had a similar experience when he dreamed of a construction accident. Years later he was at work one day and realized that this was the events of his dream. He called the guys away from the area and the accident he dreamed of happened but he saved the guys who died in the dream. My grandmother and aunts had this a lot more than my mother or brother but I didn't see them much. If this has happened to you more than once or twice, please contact me either by replying here, or posting a comment on my channel or email [email protected] I used to be a research scientist but that has not made me deny things I have experienced first hand. I am aware of the alternate explanation that people dream things all the time and we only notice in the rare instance when the dream comes true. Three people with the same dream and a dead girl found exactly where the dream had shown is pretty convincing. Saving a bunch of guys from an unforeseeable accident because of a dream my brother had years before he went to work there is also pretty convincing. I am interested in hearing from anyone who has this happen more than once, especially interested in meeting people who have tried to enhance the effect or get the dreams to happen more often.

    2:00 I used to have a very good friend who was an Nuclear Engineering Lab Tech aboard a Nuclear Sub, in the US Navy. My only problem with this video is it takes risk assessment out of context: per kilowatt of energy produced, every renewable energy source: including solar: creates more and deadlier waste than Nuclear Energy. They're also more dangerous, since for every Chernobyl, there are thousands upon thousands of people who die falling off of rooftops. This isn't to say that Nuclear Energy should be taken lightly: it can be more dangerous than any other energy form. But the people in charge of Nuclear Energy manufacturing have found safe reliable methods that make these non-factors, especially when compared to other forms of energy.

    What if the "edge" of the universe was an inside-out black hole, or at least acted as such? Imagine a flat plane that only seems to stretch out infinitely, but if you were to zoom out enough you'd see the edges start to curve downward until they drop off straight downwards infinitely, just like the flat plane representation of a black hole. The resulting diagram would be shaped like a really big cylinder. I've watched so many of these I can't recall if this idea has already been thought up or not, but i thought I'd bring it up anyways bc i think its an interesting alternative idea to what the "edge" could be

    The bottom line take away from the watches is this, the watch that is in motion illustrates the difference between a dielectric field with an active plane of inertia and is expanded to the watch that is stopped representing a dielectric field that has a plane of inertia that has stopped and the field collapses. These collapsed dielectric fields IMHO are what makes up what is referred to as dark matter, scientist know that something is there but the monitoring equipment cannot detect them, they can only see how they affect other objects. these collapsed Dielectric fields exist right on the line of -time/space and +space/time and oscillate between existence and non-existence simultaneously from our view as the observer. The distinction between matter and detectable matter is what is missing in most areas of thought in regards to this subject. Before you can understand the fabric of existence you have to consider that we as humans only see a tiny tiny tiny fraction from our point of view. In order to understand the cosmos you have to understand the Mandelbrot set as well. Read: Theory of Natural Philosophy Roger Joseph Boscovich 1758 Teslas mentor

    This is awesome, but has VERY little backing in science. We have, by no means, proved the existence of separate universes. This is beyond speculators, this is presumptuous, immensely so. None of this is proven. It has some science to it, and several various hypothesis, but science has not proven the existence of parallel universes pr white wholes. Very little from either String Theory and /or Quantum Physics have been proven. This is wonderful sci-fi, unfortunately this doesn’t constitute as factual.

    From what your saying in this video, pulsars, with their massive gravity, should basically be frozen to us relative to the distance that we’re viewing them from. Yet they still spin likke a whirling dervish and we can see their incredible rotational velocity, some exceeding 700 rev/sec for at least one observable neutron star.

    there is not "other side" to a Black Hole because it is not a 2d plane or flat surface, get it? It is fourth dimensional, as in 4D SpaceTime and everything fall towards its own center, its own original state of matter into energy radiation, spooky right? Ask Srephen Hawking

    You have attitude problem when I say so. You dirty communist. That is what big research needs. No private ownership. As the Iron Curtain crumbled, people often joked, “Marxism is dead everywhere - except American universities.” The stereotype of the Marxist professor runs deep. But is this stereotype grounded in statistical fact? Here are the results from a 2006 nationally representative survey of American professors. The survey asked if the professor considered himself “radical,” “political activist,” or “Marxist.”

    Consider this. It is estimated that our sun rotates around the central black hole once in every 250,000,000 years. So in that 4 billion years our solar system will have orbited the Milky Way's central black hole 16 times. Our sun will have consumed most of its hydrogen fuel and will have expanded into red giant possibly larger than earth's orbit and the earth will have been consumed by it. Don't worry about any of that because through our own stupidity we will destroy ourselves long before any of that happens.

    I discovered the sun it literally a white hole and a black hole and. In my own opinion. I can see the sun using my two eyes. The sun exploded through my eyes and spinning like a wheel in a car and it turned very fast.
