Where Did The Universe Come From? With Prof. Geraint F. Lewis

[@EventHorizonShow]

Do you think there was a universe before ours? Where Did the Universe Come From? And Other Cosmic Questions: Our Universe, from the Quantum to the Cosmos by Chris Ferrie and Geraint F. Lewis (affiliate link) amzn.to/3oBQyW7

[@betelanus]

Isn't that what Roger Penrose once proposed? If I remember correctly he claimed that there is evidence in the cosmic background radiation from the universe before ours.

[@gluonone]

I would say yes. If you look at the history of scientific discovery, things\events don't just occur once- there are usually many instances, to say the least. I don't think it's a stretch to think that the creation of universes have happened prior to ours

[@thealexanderbond]

It's certainly interesting that this universe was set with with the laws of math and the law of natural selection/evolution already built in. Quite strange...

[@innocentbystander3317]

In relation to universes of space/time, define "before," sil vous plait. Maybe also "ours" while you're at it, just for sihts and giggles.. The way I see it, if there is some sort of inflaton-field outside our "universe" in which other universes can exist and/or come to being, then that would be a different framework of "time" that is completely separate from ours and could even operate or be "sensed" in a manner we could not fathom. The point is, "before/during/after" are causal concepts that likely do not apply beyond our universe as we currently understand it.

Regardless of time or multiverses...What bugs me the most is no final answer can ever explain how the very first 'thing' came into existance at all.

[@meganjperry9489]

In the beginning there was VOID and nothingness, a timeless, spaceless, nothingness. And into the nothingness came a thought, purposeful, all-pervading, and It filled the VOID. There existed no matter, only force, a movement, a vortex, or vibration of the purposeful thought that filled the VOID. Was this thought eternal? In the beginning, there was eternal thought, and for thought to be eternal, time must exist. So into the all-pervading thought grew the LAW of TIME, time which exists through all space, floating in a smooth, rhythmic movement that is eternally in a state of fixation. Time changes not, but all things change in time. For time is the force that holds events separate, each in its own proper place. Time is not in motion, but you move through time as your consciousness moves from one event to another. Time exists, all in all, an eternal ONE existence. Know that even though in the time you are separate, yet still are ONE, in all times existent.

[@deandeann1541]

@@stingingmetal9648 That may be. I think, that at death, you step outside of time and do not experience it. A second after death is experienced the same as 10 billion years. When eternity comes into the picture, anything that is possible will happen gain and again, eternally. Every experience of life, every person, every choice. The same life lived a thousand different ways, every life, lived over and over, the sum total of all possible life, all possible experience. The Golden Rule has new meaning - everyone you help, you're helping a future or past incarnation of you, the sum total of all life. Everyone you hurt, the same. This philosophy of life would leave many feeling disturbed, upset, as it implies every monster and every saint is connected at a deep level. This idea is one I have considered many times. One can hope that the monsters of history represent a much earlier incarnation of what life represents, and it is possible to better oneself through the experience of many lives. There are some frightening implications - eg Hitler may personally experience, eventually, all the horror that he inflicted, as he is repeatedly born into the generation he lived. For if in death you are beyond time, it may be that past or future has little relevance, as in the course of eternity everything must repeat. I wonder if God could be the sum total of all living things, the sum total of all living experiences, past, present and future, including all possible alternate histories,past and future. Human beings have an extremely difficult time grasping the logical consequences of infinity, ie eternity.

Why an atom? And why not, say, an elementary particle? And why even that, if that? What are the physics behind this? What evidence would you have that supports this hypothesis?

I have wondered if “Dark Matter” is a gravitational effect from a neighbouring universe. It would potentially explain why we don’t see the actual stuff to create the mass that is inferred, but we do see the effects of that mass.

[@McShaganpronouncedShaegen]

Dark matter and dark energy are theory's put forth because of interpretations of actions observed that cannot be explained by our current understanding of how and why things behave. There are two ways we can approach an explanation of these observations. 1st is to invent an unseen force that we cannot detect. 2nd is to take a look back at what we think we understand but refuse to change because the math works. Math can predict an action but it cannot tell you why and in that statement lies the answer to all of the questions these guys have.

[@adlex1212]

Dark matter was theorized because galaxies were spinning faster than expected. I don't think a neighboring universe would do that. If there was a neighboring universe we'd probably see all the galaxies flowing towards its direction, so in a single direction. Instead, galaxies are flying away from us from every direction.

@@McShaganpronouncedShaegen The Universe is a living entity, that is why it was born and is growing, and the human scale is almost at the limit of the structural basis of existence. Dark matter doesn't exist, we actually live in something dense, organic, and the unexplained forces that maintain the gravitational structure between galaxies are equivalent to what we see in the microcosm, where creatures live within the "density" of a drop of water and cannot see the "force" that limits their movements and stabilizes their habitat. Black holes are equivalent to dead cells that deteriorate all the matter around them. One day everyone will agree with me. ^^

So discussion of ideas must always represent truths. The very reason for discussing ideas is to explore which can be true and which cannot. What you are suggesting is religion, not science. Only religion starts with "truth" and rejects discussion which challenges that truth . Science starts with ideas and discovers those which are perceptibly true, allowing that those ideas be challenged by further exploration and discovery to replace perceived "truths" with new knowledge.

What would happen at the termination boundary for the observable universe? If the observable universe was all there is then it’s diameter would be transposed into a right angle triangle with length half*AB, where AB is the length of the diameter. With the new base, an angle of 89.9recurring degrees would pinpoint a maximum proportional distance for quantum phenomena. With each additional decimal place calculated for the angle the height increases. Beyond h it’s statistically implausible to define an observable quanta, as it’s more likely either side of the moment of measurement. It’s even possible that wave functions couldn’t collapse beyond this distance (h).

Absolutely love the way he talks about Simulation Theory near the end of the video, similar to the way I've personally looked at it. Obviously we don't know, but it's an extremely interesting possibility that should be getting more attention as technology allows us to start running our own simulations. If we simple humans manage to create artificial intelligence, and plug it into a 'universe/game/etc', where that 'being' questions it's environment and how it got there, it would be absurd for us not to consider the same thing. Even if WE don't live in a simulated universe, most of the 'intelligent' 'beings' in existence could one day live in simulated universes, because aliens and humans could run as many universes as we want. Of course, none of these possibilities actually fully answer the questions of how we got here, who is simulating us, is somebody simulating them/etc? But these are very attractive possibilities we must think about

[@spindoctor6385]

I personally dislike the theory. If you replace "simulation" with "dream" you get the same questions. The main difference being that we already know the human brain can produce conciousness but have no idea if computers will ever get near it. It is interesting to think of but far from realistic.

This universe is on the opposite end of a blackhole from another universe - and on the other end of our own blackholes are new universes being created. 'Starstuff. particles vacuumed on one end and spewed out the other, as it cools so it gains form.

[@Phillip713]

The universe is everything that exists in time and space. So unless we are changing the definition then any other space would still be our universe

[@MilesDavisKDAB]

Could we be a simulation within a simulation within a simulations within a simulation.........???? I thoroughly enjoyed listening to Prof Lewis but there is always something disturbing about discussing the origin and ultimate nature of the universe. Something inside my mind just wants a nice simple explanation without the need for extra dimensions, multiverses and lots of mathematics that I don't understand.

[@jamescollier3]

look for universe from nothing by Krauss

[@williamblack4006]

I don't believe we are in a simulation. I think the idea is pure fantasy -- for some it is perhaps a means to wish the universe (or certain personally unpleasant aspects of it) away, or perhaps a round about means to engage in wish-fulfillment fantasy.

Hello sir. I've been wondering. Wondering for a few days now. JWST launch is 12 days away. NASA will be broadcasting/streaming it live. Are you going to do an event or live stream or something for it? I think it would be great to hang out and witness history together.

[@JohnMichaelGodier]

It's launching just after 6 am my time, so I won't be able to do a live stream. But there will be a full update interview in January covering all the developments.

[@kefkamadman]

@@JohnMichaelGodier Still an exciting time to live in, regardless. I'm never more stoked about our scientific progression then after I watch your content or Anton Petrov's.

[@randyfox364]

More great content, thanks.

Has anyone tried to measure statistical anomalies in the probability of finding specific flavours of neutrinos generated from sources at different relativistic speeds (towards and away from the detectors)? Could this make it possible to find the masses of all three flavours of these particles instead of just the difference of the square of their masses?

[@twitchi8478]

I like the idea but how to measure something racing away at relativistic speeds, you need an interaction to measure something

[@dubsar]

@@twitchi8478 It's not the neutrinos themselves that would be racing away from a detector, but the source of these particles. What could be measured is a potential anomalous behaviour in the "doppler shift" or "redshift"/"blueshift" - for the lack of a better analogy - of neutrinos (which unlike the massless photons are shown to experience time) caused by their inherent oscillation among the three flavours - electron neutrino, muon neutrino and tau neutrino. By correlating observed anomalies (if any) with what we already know there is the very tempting possibility to zero in their individual masses.

I do like this channel.

[@superbrainbow]

What if, and bear with me here, the more the universe expands, the more tears in the form of black holes it creates? Eventually the fabric will be so tattered that it disintegrates - all the matter falling into the black holes, then those black holes falling into each other until only one massive light sucking void remains. Finally, this final black hole collapses into itself, then explodes outwards, vomiting up all the matter it digested from the previous universe, creating a new one out of nothingness.

wow, that’s an amazing video.

[@stricknine6130]

Very interesting interview. I really want to read the book now. Thanks for the episode.

Hmmmmmm. Commented 4 hours ago when the video was released just 27 min ago. 🤔🤔🤔

Also, with the regard to physics divorced universes outside the visible universe and the conundrum of homogeny, is it possible that the universe is so big, we simply can't see portions of the universe which are less homogenous of our own?

[@RJay121]

Can't wait to see what helpful pieces Webb will uncover

[@frankschneider6156]

Because the speed of light is limited, we can indeed only see portions of the universe (called the observable universe, which is just a part of "the" universe) and not any more. We can't in principle observe the rest. We can't therefore know or observe (and never will) how large this rest is or how it looks like, if it is less homogenous or not, or if the missing antimatter is just located there. But as that part of of the universe can never be observed, any speculation about it can not be falsified and is thus not scientific in nature. You could hypothesize, that that's the place where Elves, Dragons and Unicorns are living and will never be falsified. Meaning: speculations about that part aren't leading anywhere from a scientific point of view.

[@triqpham]

I prefer the way JMG speaks in this show as opposed to his own show. I find it harder to understand him on his show because of the unnatural cadence in his speech. He has a deliberate up and down rhythm in his speaking on his show, if that makes any sense.

Imagine the classified scientific discoveries the military industrial complex has. I bet it would blow our tops off.

[@MarkYoung-l8f]

H-p +(n) That is what the primordial Universe was made of. In English it is "Neutral Matter" Specifically Neutral Hydrogen with no Positive or Negative Charge, So no Nuclear Force, Electro Magnetic Force and only very weak Gravitational Force. Therefore no 2 Neutral Hydrogen Molecules could interact. The pre Universe must have been a molecular cloud circa 10Bn ly diameter. The gravity caused the centre of this Molecular Cloud (circa 1-3bn ly) to form a highly compressed dense core. Eventually the extreme compression caused 2 of these molecules to be so close that friction caused a single spark which caused a cascading electrical storm. Hence an Electromagnetic Force was born. (lightening rips apart molecules in out atmosphere) Upto 3bn ly of this dense cloud ripped apart the Molecules in the core area. The resulting cosmic particles reaction was to re-combine in any way possible creating a strong Nuclear Force. Much of this core was turned into Positively Charged Hydrogen. This created the Weak Nuclear Force and Gravity which formed the basis of the Matter leading to Stars being formed. The outer 7bn ly of Neutral Hydrogen remained. We call this Dark Matter. That Dark Matter is today loosely bound to the edges of Galaxies, Globular Clusters and Large Molecular Clouds. It remains non interactive with the matter in our touchable Universe as it has no Charge. That is the sole reason 1st - 3rd generation Stars are all formed from Hydrogen. Neutral Hydrogen became Charged Hydrogen through a single spark. Just like life on Earth was caused by electrical storms and Hydrogen Sulphide. Early life (non oxygen breathing) fed on H2S. Today 28bn years later, most stars are still 95% Hydrogen. Except those near the end of their life span. All you have to do is ask "Where did all this Hydrogen come from" ? There you go.
