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
Dr Sutter you give such wonderful talks. They make me want to (try) to learn more
Great video!
Love your videos btw! Thank u!
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.
Good video I listen while at the factory 🙃
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.
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
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?
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.
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?
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?
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....
It’s all about The Bulge 💯
I have searched rotating universe before on UA-cam and this video didn't come up.
What is with the algorithm ?
can we also go to our past in a universe with 2 temporal dimension?
Spinors by Penrose and well quantum vacuum of meta verse
The universe idea reminds me a cell with membrane
What u think of Mandelbrot and Newton fractals;)
One last think spin of an electron is said to be but a gittering of a point charge and creating E/magnetic vector field that covers the imaginary sphere in helix 🧬 like pattern as I understand
What if the universe is just jittering and we r exactly moving along of all experiencing it
I'm back. I will be here for a while.
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?
is time travel to past future really possible and how i want ti do i am from india please help me out
I have few ideas about all; hey astrophysics degree from Russia 🇷🇺 20 years here in the states thoug and it’s recaptured me lately thinking to go back into field 😊
My mind is now spinning.
What does Guate have to do with it?
Do you ever let people finish what they are saying?
18:22 a wasted opportunity for a time travel joke 😞
If the universe is rotating, is there a point around which the whole universe rotates?
Like a Griffith pendulum of better red shift look up where we r in relation to big bang, either the universe is rotating of fluctuating like pendulum
There is an idea ..
Does our universe/cosmos rotate? Yes it does. And; it is expanding into the infinite "void" which surrounds our universe/cosmos.
Also so hard not to think it’s a mind playing game and a simulation providing all mathematical perfection we r uncovering) of all and we r in a right place
If that is time travel , then recording a video would also be time travel.
Huh?
Universe is spinning. Galaxies are spinning. Planets and Suns are rotating. Sounds like dynamo's.
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 .
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.
Drink enough alcohol...universe spins. (how to measure spin rate?)
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.
Lol earth is stationary, storms & winds come from the perpetual motion of electromagnetic core still spinning
I miss seeing your face
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.
First!
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
