Ok, time for a correction! 5:05 "the rocket engine and boosters" - main stage (orange tank and 4 RS-25 engines underneath it) is indeed hydrogen powered. BUT the boosters (smaller white cylinders, on the sides) - are good old solid rocket booster, almost identical to those of space shuttle era, just a bit longer. There is no hydrogen involved there at all.

Where are the worms that are responsible for these worm holes? Perhaps we should look on the planet Arrakis?

"just because there's math for it doesn't make it real." Please keep saying this!

Your grounded, pragmatic approach to astronomy and physics, Sabine, is refreshing. I also quite appreciate your dry, ironic sense of humour… Yes! The idea of a “static” wormhole can be made to seem “real” with mathematics, but so could Le Verrier in 1859 use mathematics to make the “existence” of Planet Vulcan between Mercury and the Sun (as an explanation of observational peculiarities in Mercury’s orbit) seem real: there was no planet there, at least not in *our* space-time…

I have started to think that life is 'Fractalian'. Just a whole lot of rinse and repeat until failure intervenes. I have never understood how chaos is related to fractals, but if it is, we could use a big bifurcation right now IMHO.

This may be the most important news source on this app

I realize that this is not the same as how many atoms are simulated in the largest classical simulation since that simulation would have many simplifications which may not be needed on a quantum computer.

It wasn’t a wormhole

The high matter densities like the earliest stars and Black Holes could cause extra space to come and fill the low densities in space, increasing the wavelength of light while increasing the expansion rate between matter, and making the Dark ages in the early universe. Thank you.

Hi Sabine, what really makes wormholes unstable? Their geometry or density?

@justsomeone461

Жыл бұрын

From what little research I did, it would appear to be their density above everything else. It's reeeeeeally hard to cram SO MUCH EXISTENCE into a constricted region of spacetime, so they're dying to fall apart. Unrelatedly, are you of Turkish descent?

You could measure a wormhole as if it were static by conducting measurements against light paths from the same moment but arriving at detectors at delayed offsets. We'd be measuring a static wormhole in a dynamic universe with the right timings even if measured at different moments in our relative reference frame. For eg) a mirror reflecting light from the sun to an observatory could measure the sun at the same moment of the sun's life but at different moments on earth due to the constant speed of light on a longer path. Gravitational lensing would lengthen paths measurably too, for another example of how to go about it in theory. A static wormhole measurement could still be verifiable under perfect circumstances.

Black hole theory is based on a mathematical misconception. For some reason people don't know that Einstein said that singularities are not possible. In the 1939 journal "Annals of Mathematics" he wrote "the essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of GR predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light." We have all heard the phrase "mass becomes infinite at the speed of light" this phenomenon is illustrated in a common relativity graph with velocity (from stationary to the speed of light) on the horizontal line and dilation (sometimes called gamma Y) on the vertical line. Mass that is dilated is smeared through spacetime relative to an outside observer. The graph shows the squared nature of the phenomenon, relativistic effects increase at an exponential rate the closer you get to the speed of light. General relativity does not predict singularities when you factor in dilation. Einstein is known to have repeatedly spoken about this. Nobody believed in black holes when he was alive for this reason. Wherever you have an astronomical quantity of mass, dilation will occur because high mass means high momentum. There is no place in the universe where mass is more concentrated than at the center of a galaxy. According to Einstein's math, the mass at the center of our own galaxy must be dilated. In other words in some sublime way that mass is all around us because as the graph shows we are still connected to it.

Excellent, so informative and fun. Keep them coming. Thank you.

I love you and your channel

I know what the authors are trying to do but the problem is that the hypothetical surface of a wormhole is some sort of barrier between the normal spacetime equilibrium and a lower density field interior column on the inside. Aside from the very critiques you make, a worm hole is not gravitationally rounded, if it had an amount of energy that could warp spacetime like a black hole, it would be gravitationally rounded. If you could stretch the energy out like a worm, it would just collapse into a black hole. So lets make the comparison fairly, the unit of foam we can imagine as spacetime gets flattened like a pancake near the event horizon of a black hole, as a consequence lateral motion is allowed and verticle motion is empeded. If you are at the event horizon you dont notice the change, but an observe far enough away from the warped space notices you time slows down. We dont know what happens to spacetime inside a blackhole. For a wormhole to work you would not neccesearily need the unit of foam to flatten like at te BH event horizon, but it would have to be shaoed such that the evolution of spacetime moved around the interior manifold of the column and then out the otherside. Meanwhile the spacetime inside the worm hole would need to be elongated and spiral inside the same manifold equilibrating with normal soacetime at the terminus. This differs from what is going on within the blackhole since there is no flow (things flow in infinite time) So if we were to inspect a small area of a wormhole and compareit with an event horizon we might notice some similarities, but if you extended the comparison it falls apart. Wormholes of the Suskind variety are almost as dubious.

I'm an aficionados of the Pink Floyd. When "The Dark Side of the Moon" appeared in the spring of 1973, I had a cheap BSR disc player with a sapphire stylus with 50 hours lifetime; I played the disk continously until the sapphire bit folded. The morning after I splashed all my rainy day funds on a diamond stylus (~1000 hrs) to keep listening the disc - especially Time and Eclipse. Time went on, studying science, history and philosophy. I later used the phrase "Dark Side of the Moon" in all my articles and writings, partially in recognition of the masterpiece that captivated me as a young person. Around circa 2010, I begun receiving feedback with the appellative of "ignoramus" for every article or post where I mentioned the "Dark Side of the Moon"; all the Culture Warriors on the Internet pointing out my poor level of knowledge in astronomy and planetology. It is 12 years now that I blacklisted the phrase "Far Side" from my keyboard dictionary - so I can't write it even if I want. I may have been off topic I know; I love the Moon and the Pink Floyd!

@@xfdrtgfd you're welcome, I love to talk about space exploration. It's just hard not to be salty about it after what was happening for the last 30 years. Yes, original proposal was to make a rocket from Space Shuttle SRB, Space shuttle external fuel tank, Space Shuttle Maine Engines and Orion space capsule (with additional upper stage in between as later development). Supposed to be quick and almost no RND costs. This was after Ares rocket was cancelled. Ares was basically the same as SLS except it was developed during early-mid zeroes and then scrapped. Actually, before that LM and Boeing had a proposal for Moon architecture using in-orbit fuel depots and eventually on-Moon fuel manufacturing (at least of oxygen) using nothing but Atlas-5 (fuel depot was a modified Centaur upper stage with large shade). If we went with this way there would be a decent research outpost on the Moon already and for less money than was spent on SLS development. Today SLS is kind of outdated already: NASA can get the same performance from expendable F9H + some high energy upper stage (will require some development though) for fraction of SLS price, or buy Starship booster which would cost even less even if expendable and have more capabilities than SLS.

Can’t we keep wormholes open by supplying a negative energy pulse? I saw something on this when a group of physicists at Google Quantum labs virtually simulated a wormhole in a quantum computer, fired a steady pulse of negative energy (not sure what that means tbh 😅) and showed a qubit enter the wormhole and appear on the other side instantaneously thereby proving ER = EPR. Of course this was a simulation but does that imply we could do it in reality?
