We live in a 100% magnetic universe..... it's that simple!! The center of a magnet is by far the most powerful part!!! that's where you will find anti gravity and most everything else. STUPID HUMANS!! We went backwards in the Iron age!! the center of a magnet is where we belong after all that's what we are all configured with..FACT! Please review the works at "CORAL CASTLE, Florida. (KZbin), He would "VIBRATE" ,, not oscillate the granite at a resonant frequency to the type stone he was working with. Granit has allot of magnetic properties given it's make up... You just need to vibrate at the correct freq. and it will become workable. Keep in mind we are talking about vibrating only the "B" field of a magnet into the rock!!! You will note at Coral Castle he also had a horizontal stone , similar to Stone Henge... All his magnetic generators were in the repel mode to maximize the "B" field.. SIMILAR TO THOSE Shown ON THE PYRAMIDS OF EGYPT.. FACT!!, THINK about it THAT'S exactly why they used copper tools!!!! You must use copper tools and any iron would totally dispute the field. Quantum Math is total B.S. E=MC2 is also total BS... E=MD. (Magnetic density). Thanks Vincenzo.. Please use your brain!! If your professor gives you any flack, have him explain the speed of magnetism. It's instantaneous. That's how they used the pyramids as transportation devices, inter Galaxy type transportation that's exactly why they were 8 sides to create a perfect hologram from earths magnetic field that could be used to connect interglacially

44:00 Watch a great question come up..

[@HarryNicNicholas]

my career was in computer graphics, i worked on the bbc series "the planets" and i've done a multitude of simulations, the soho project, the oort cloud, (and a few feature films) i'm glad you say "cartoon" rather than graphic, it's good to have the distinction between a animated computer graphic (like i would do) and a simulation from actual data. interesting at 34:00 you say maybe there wasn't emptiness, i was trying to imagine a big nothing, which is hard, but by trying to imagine a solid / liquid of dark matter extending forever which then has that "bubble" that explodes i can sort of picture: "something" going on forever is easier than trying to imagine "nothing" going on forever. also i've been trying to replicate bubbles in computer graphics, with mixed results, but if "our" universe is a bubble or rather a sphere, and other universes are popping into existence around it, then you get a huge (infinity) number of galaxies in no time, even if you had four spheres of equal size, to fill all the "empty" space with tiny expanding bubbles would be an awful lot of bubbles, and if they are all expanding and multiplying, you get a really big space filled in no time, again i find that easier to picture (!) than a vast emptiness, even if the bubbles shrank and collapsed the space would fill with "new big bangs" i think this is something like the " Banach-Tarski" thing. . time for my medication...

[@antoniomiguel3789]

One question remains: what was the source of hydrogen, from which other atoms were generated?

[@metal134]

Antonio Miguel Well, I'm certainly no physicist, so take my answer with a grain of salt, but my understanding is that energy coalesced into the various subatomic particles, which then coalesced into protons and electrons and, in this fusionless state, matter can only exist one proton and one electron.

[@20july1944]

134: That's what physicists claim, but energy *never* coalesces into any particle of matter in the current world. All relevant natural processes are entropy leading to heat death and involve matter being turned into energy. I don't see how the big bang's high temperatures or pressures explain why ALL the energy didn't "coalesce" into matter as it lost "energy" or specifically lost "thermal energy."

Don't you want to be able to say" the higher dimensional Multiverse is a paradigm in human understanding equivalent to the grudging acceptance of the fact that the Earth isn't the center of the cosmos. That the Earth goes around the sun not the other way around. "

[@donsamv007]

what is the universe ? Is it like a black sheet of paper with white dots or a black cube or a black sphere? If it's finite , wouldn't expansion of the galaxies stop at some point ?

[@davidlawrence4467]

If it's like a sheet of paper, it will expand forever, as if the paper was able to keep getting bigger forever. If arrows are drawn on the paper starting at one point, they can be extended indefinitely. if it's a sphere, it will eventually collapse in a "big crunch". If arrows are drawn on it starting at one point, they will eventually converge. Think of the lines of longitude on the Earth, starting and ending at the poles. As for a cube, gravity will pull the cube into the shape of a sphere.

[@jomen112]

You can bound an infinite space to a limit volume by having a metric that bounds it. E.g. if you do stereographic projection of sphere to a plane, the surface will stretch to infinite but the area will still be bounded by the radius of the sphere. What controls the expansion is the metric (the radius of the sphere). That means even if the surface stretch for infinite the surface area can still shrink or grow dependent on the radius, i.e. "curvature", of the metric. Hope that help you to somehow visualize how something can be infinite but still bounded and expand at the same time.

It's not that weird to at least be open to the possibility of a multiverse. First we thought it was just our sun, then we found out all the stars out there are more "suns". Then we thought there was 1 galaxy, surprise, there are more of those. Why stop with 1 universe? Of course you shouldn't believe it until there's multiple pieces of evidence, but be open minded.

[@zeroonetime]

"Everything must be very simple but not simpler" Albert Einstein

[@Winkkin]

I think the young man was asking "Could the expansion accelerate to the point where the expansion over a Planck 'second' will exceed the Planck 'length', resulting in a dissolution of space itself."

[@brentvfreiberger]

Winkkin That is a very good question. The expansion can accelerate faster than light speed. This is not motion through space but rather an expansion of space-time itself. It is an unanswerable question since recession of such velocity would be unobservable.

[@Aluminata]

A no longer existent past, a "now" of zero duration, followed by a not yet existent future.

[@StraightShooter01]

Ok follow me here if possible because I don't know if this makes any sense. Preface thoughts: looking into space is looking back in time, the CMB as a recorded event at the 'beginning'. the events of our existence are rushing away from us at the speed of light. Adding just a couple more thoughts to this stew then we can postulate. If indeed there is infinite space, you could pick any direction and eventually 'hit' something even if that direction is toward the Bootes void - my understanding of infinity is such that there is some form of matter that we would eventually hit. Now while we agree that time travel itself might not be accepted as possible, my questions or postulations are regarding a characteristic of light - reflectivity, refraction. We look in a mirror - we are looking into the past albeit its very close to the present - its still the past of what we used to look like. While it may not be possible to 'go' into the past - might some form of reflectivity allow for us to peruse the past? How might we 'look' for these reflections? Is it possible that these 'reflections' if detected might be confused for intelligent life other than ourselves by mistake? How might one be able to not be 'spooked by a reflection' by passing a mirror in a dimly lit hallway of space? Just an exercise of imagination I thought I might share. Thanks for bearing with me. Janna Levin is great, thanks for posting video.

Thomas Pulawski only if it's absolute known fact

[@pulawski]

Xxen So, please give an example of an absolute known fact in physics.

[@TheCliffy007]

Thomas Pulawski this round ball is a sphere... light travels through space...

[@pulawski]

Xxen Well. A "sphere" is a mathematical concept, so, nothing to do with physics :-). The concept of a sphere entails a three-dimensional object where all points of the object are the same distance from a chosen point called the centre, as you probably already know. If you are implying that you have a ball, which in reality you will try to prove is a sphere, you will fail. The earth is not completely spherical (consider the mountains), the sun is not spherical, since it can be measured to ripple. A plasticball in your hand will show to have grooves from the tool which cast the ball. Even the most perfect sphere, which they are trying to manufacture to find a new definition for the kilogramme, is not spherical if you zoom in to atomic level, which will show a bumpy surface (google images of carbon atoms). This is the core of the problem; even if you had the perfect sphere in reality, atoms have been measures to have a "fuzzy" edge, so in the minute detail, your balle with be fuzzy at the edge, and this will prevent to prove it a sphere. Well, you say, these are deviations so small, that they do not matter. Well that is exactly the best physics can do; to demonstrate something to such an absurd level of confidence, that is it crazy to think that anything else may occur. But..., we cannot even prove gravity. Just because we have shown a billion apples falling to the group, we cannot prove that these rules are in effect on a planet in a galaxy millions of light years away, or not. It is just very improbable that they are not. "Light travels through space" is interesting but not proven. It is simply a way we use to describe what we see, in a way which explains all observed phenomena of light; travelling through space, and that have not been disproven yet. So it is very improbable that it is anything else. But how do you prove that it is not space which whizzes past the stationary light, or that light is ubiquitous and everlasting, and that it is only some quirk in time that makes it look as if light shoots through space. I know these are ridiculous suggestions, but they point to the issue: that you cannot prove that it is actually light travelling through space. Only if someone makes an contradictionary observation can you prove it false, but you can never prove it true. Just as the old astronomers though that the earth was the centre of the universe (no one really ever though the earth was flat), and this was the accepted theory simply because they did not have sufficiently accurate instruments and observations to disprove it. No one is guaranteeing that todays observations are the final ones, and that they will not be refuted by future contradictionary observation which will throw everything we know on its head.

The particle thing was not was she stated. She was saying if particles could think we could never predict anything. Because you could never know what path something could take especially if it THOUGHT to changes it path with no other force applied. Thats what she meant, nothing to do with consciousness at all. But because particles do it think individually them we can use science and math to predict any outcome. That’s why the weather will be predicted even better soon with autumn computers computing the particle trajectory. Imagine if they could think, we never would know the weather. Lol

[@ultarnerd]

An alternate theory that says time dilation by gravity contracts matter in a way that's is very different from Lorentz contraction where objects measure shorter if traveling fast enough ,means space around gravitational masses contracts non moving matter in a way that's indistinguishable from space expansion.A lot of effort time and no physicists I have dealt with were able to argue how its just another Lorentz contraction.Thing is if matter actually contracts under gravity due to its time slowing effect then even a black hole, if you could observe one from the inside during its creation would give the same description as given for inflation theory.Model goes on to examine how the quantum vacuum is actually space and is responsible for putting mass in its place so that space can exist in other words it is actually space.There is so much stuff here that try looking at my KZbin videos for a crude and incomplete review.Seriously worth your time.

[@rickjames4731]

+ultarnerd I did enjoy your post, trying to grasp it all. I can see how time would slow down and matter would contract but are they not just the way thing are under those different sets of physics or do you sim;ly need to speed up time to observe?

[@ultarnerd]

Rick James You will see time speed up from earth to a stationary satellite its just not much.Its a lot from near a black hole.I did a you tube on some about how a ward drive would look it it was where time would be faster in an alternate white hole so from the prospective of the craft it would be like the whole universe were near a black hole while the craft is not.This theory leads to a whole model that leads to the possibility of actual warp drive if one can decrease the quantum vacuum.Best speculation now is that negative energy must have negative centrifugal force meaning spinning a ball of it can never fly apart but without an ant anti gravity it would repulse matter so its hard to get inside.Bst guess to a series of particle beams doing something like the casimer effect and some guesses about how our universe has no antimatter so see my you tube on it for a bit more but even its incomplete as I forget so much when I make them.Ill be doing some more on cryogenics and some clever alternatives and some science experiments Ill try when I get time.

These talks owe more to good Journalism than streching the bounds of Science, because they're meant to inform of course. So comment on the topic and wether or not it's matched to the content is superfluous after the fact, ..not in the context in which this was meant to be understood or accepted, which is a lot like the Lecturer restricted to the Institutional Curriculum.

[@stupidas9466]

carl green actually, if you think about it if our universe was just in a petri dish then our universe wouldn't just be in a petri dish but include the petri dish itself. And if that petri dish was somewhere that somewhere would also be part of our universe. Now, if you're speaking about the "observable universe" then that is a different thing altogether.
