New video I'm about to watch, but im gonna take a leap here and say we can't tell if its rotating from our perspective within it. For all we know, it could be spinning so fast its causing space to expand in all directions and can explain dark energy.
If you cant explain it with physics or laws, even if somehow the universe put the answer in your head it is not a possibility. We must follow our laws and physics on earth. If physics are different elsewhere we will never understand the universe. Everything we know is built on physics.
"Hey Einstein, I want a universe that rotates!" gave me a chuckle
I'm pausing the lecture right at the moment you mention universal rotation about every point. Would this imply the rotation is about a spacial axis that's in a higher spacial dimension than the 3 we can perceive? Would that also be the mechanism that enables backwards time travel in this artificial model of the universe? I'm sure you will likely cover this, I just want to have my though process explained prior to the big reveal, if it is in fact coming. That way I can't claim in retrospect that I was already realizing where you were heading after you'd already gotten there. It also means that if I'm completely misguided in this line of thought, I'll look like a total doofus (which is totally fine with me too). This is a truly mind warping concept. I thoroughly enjoy your content, and your new format makes it easier to consume without worrying if I'm missing a small bit of visual aid.
From what I know the most logical explanation so far is space and time are flat and potentially infinitely big. There is no curvature found in space and time unless it's around mass. This is why time travel backwards is not possible as Dr. Sutter explains and I agree. We only say big bang is the start of space and time because it's the start of what we can observe, and strangely enough what we can observe is a lot of circles and spinning things. Which could be strange. Keeping in mind we can't really observe dark matter or dark energy as we don't know what they are. We only observe the effects from them around what we can observe. This means that space, time, dark matter, dark energy all could have existed infinitely and there is no way of observing anything prior to the big bang. But no one can say these things which make up the bulk of the universe didn't exist before the big bang. One could even argue that if you keep going forward long enough, eventually you'll come back to where you are in the sense that eventually things have to repeat themselves. Of course this would be an astronomical long period of time and part of what Penrose hints at with CCC. Even though I think CCC is a far cry from reality of what happens, the idea that stuff remains forever and the concept of space and time are next level in CCC. Then you are left with questions we aren't even close to which are how would the universe look to a photon?, or to dark matter?, or to dark energy?
Good video I listen while at the factory 🙃
Thank you for your videos, very infomative.
Dr Sutter you give such wonderful talks. They make me want to (try) to learn more
Somewhat related to Peter Kallend's comment below, but isn't there a more fundamental condition that makes the rotation of the universe impossible? Specifically, that rotation is something that can occur only in relation to an exterior point of reference. Everything in the Universe rotates within the structure of the Universe. But to refer to your episode "What's Outside the Universe", the concept of something external to or encompassing the Universe is by definition nonsensical - the term "Universe" refers to all that is; there is nothing external to it. (As you noted in that earlier episode, even assuming a multiverse, there is no way to stand outside our Universe and observe it from within another universe, which makes "external universes" irrelevant to the discussion). So, if there is nothing in which the Universe "sits", there is no way it can be said to rotate - there is no frame of reference external to it.
Wait I don't think I understand it. Like you said we've "found" other ways to time travel that involve non existing things like negative mass. This way involves another (possibly) non existing thing - rotating universe. Whats the big difference? Only that theory of relativity does not allow negative mass but does allow rotating universe?
In northern hemisphere water goes clockwise. Southern hemisphere the opposite. what about on the equator? I'm perplexed by to time travel backwards everything that exists has moved so u cant reverse it. like perfume diffusion u can't put it back into the bottle....
Anyone have an animation link for a SPINNING, EXPANDING Universe?
What does it do to flatness measurements?
Paul, as always good information, BUT, I really miss seeing your face. What happened, camera got lost?
I have searched rotating universe before on TH-cam and this video didn't come up.
What is with the algorithm ?
Maybe, at a "universal" scale and considering "infinity", the motions we might observe or eventually predict might appear chaotic and not as "synchronised" as those observed at smaller scale (our solar system). "Rotations", revolutions.... do make sense in our "observable dimension", applying the 4 laws, but on a greater scale could there be a 5th law that will change the pattern? And why one unique universe? How about multiverses with laws altogether different or even opposite?
How do forces behave with one another? Can they be magnified or cancelled according to circumstances?
And would halloumi cheese survive a black hole?
Great video!
is time travel to past future really possible and how i want ti do i am from india please help me out
Surely if the universe were rotating there would be a distortion in space caused by lagging and that would be testable by a bending of light heading towards us?
can we also go to our past in a universe with 2 temporal dimension?
A naive question: why the spin of the milk way is not creating time paradox? Lets assume in the far future the entire universe crosses the particle horizon and the milk way becomes isolated from everything else in terms of causality. Would in this case the spin of our galaxy create time paradox?
I'm back. I will be here for a while.
What does Guate have to do with it?
Do you ever let people finish what they are saying?
If the universe is rotating, then it has an axis. This might be part of why scientists reject it out of hand. Thank you for covering it though.
My mind is now spinning.
If the universe is rotating, is there a point around which the whole universe rotates?
It’s all about The Bulge 💯
If the universe is rotating, maybe the red shift is due to the rotation, not inflation and expansion.
Commenting to feed the algorithm 🙃
18:22 a wasted opportunity for a time travel joke 😞
Does our universe/cosmos rotate? Yes it does. And; it is expanding into the infinite "void" which surrounds our universe/cosmos.
My head is spinning ;)
Huh?
Universe is spinning. Galaxies are spinning. Planets and Suns are rotating. Sounds like dynamo's.
If that is time travel , then recording a video would also be time travel.
Paul, please catch up… there are greater things afoot. The old paradigm is dead: observational truths now massively outweigh the theoretical constructs of the mathematicians who have derailed science for decades. We are at the cusp of a new era in physics, & cosmology. This is a very exciting time to witness & be apart of. Be brave; be objective & critical, be true to 1st Principles & the scientific method.
We're moving due to pressure mediations and the right hand Rule of electricity which is magnetism spiraling along with everything else tubularly magnatude.
Gravity is Not a force
Gravity and Time are created by pressure mediations.
A black hole is a super mass with no magnitude . The dielectric creating the toroidal field of magnetism uver powers the ability of anything with magnetism & magnitude to exist.. Recycling every element back into Hydrogen which all elements are compounded complexities of.
^ TRUTH
Tesla referred to Einstein as "a fuzzy headed Crackpot" < fact
Look up Kenneth Wheeler to learn more truth about the metaphisics of cosmology .
at 30.29 you say we can also travel into "OUR OWN" past. I disagree. If we even manage to figure out how to travel into our past, NATURE will send you to an alternate past timeline so you cannot do any damage to the timeline from where you came. This is so obvious that I wonder why so many learned scholars keep insisting on the "Grandfather Paradox". Nature is always one step ahead of us mortals.
Drink enough alcohol...universe spins. (how to measure spin rate?)
Something special about about all the balls of plasma in our universe. Could they be the links to the web? From one end to another they could all be "connected" some how? With out light nothing would exist regardless, no? I understand there are forces out there much more powerful and majestic than starts, but something about the untapped potential of plasma
Lol earth is stationary, storms & winds come from the perpetual motion of electromagnetic core still spinning
You can do this by refracting light , until it fall back down. Let's say you had a planet / large body , with many layers of air , light could be produced at one side of the planet , and bend/refract back to the source.
Something like this is very close to a closed system, magnetism ,and very low frequencies are ways a system like this can lose energy .
A sphere of light trapped by air , wouldn't look very interesting, there is nothing to see .
There would be no multiverses just one infinitely expanding verse with time and expansion, nothing would rotate just a linear plane without dimensions. I miss Newton, he tried to teach the sight for the unseen unsuccessfully something I think Tesla also had. I cannot accept a lifeless universe that is not spinning, sorry.
I miss seeing your face
Most flat Earthers believe Earth is stationary!!

you can go back in time but you cant go back into the same spacetime. because you are in it and you werent in it. so its different spacetime, its parallel spacetime. you can change everything there no problem you can change past of this different spacetime but original timeline is unchanged.
its so no brainer its boring
First!
