@@Kritiker313 I do believe the area CTT delves deeply into that might be effective for the dormant thinkers is "consciousness"! The fact that we are aware. Perhaps the cosmos is vast, but at this moment, humans are all we see as intelligent life. The random violence, hatred, resource wasting/hoarding must be stopped, willingly. The teaching of our uniqueness would penetrate many more minds if presented as school curricula instead of the curiosity based access you and I currently excercise.

One consequence is that, since anything that can happen - anything with a non-zero probability - must happen. Since you (or I, or anyone else) had a non-zero probability of being, we were all necessary beings who *must* have come into existence at some point in spacetime. Also, any fictional character that can physically and logically exist actually does exist in some part of spacetime. There are probably some other philosophical implications, but that's enough for now.

@Lord Methane When you get at this level, there is a LOT of theory and a small amount of data. I would not use the word "trust', it is theory, not fact. It is a fact the earth rotates around the sun for example. But we don't even REALLY know the universe is exapanding and the rate, it has so little data that when we discover new data it can lead to different theories. I think the 'dark energy' theory is NOT something 'all' agree exists.

I'm curious about what does the first microsecond of the universe can be or even if it can be a thing at all since before there was an earth that revolve around a sun and us to develop the concept of a second that is tied to the speed of the earth/sun system, there would be no way to determine the duration of a second. You can say then, what about an atomic clock? Well, then again, this can track time accurately at our scale on earth, but what is the frequency of an atom from which we could measure the duration of a second before such atom was ever created or ever existed at all? What was a second before there was time to define it?

Brian Green can. Actually, any number of books go over inflation. Basically (and from memory) you need only start with a very tiny patch with an enormous energy density. Once that inflates to universe size, the decay of the field causing the inflation will fill the new space with energy (that creates hot dense matter). The hypothesis is that the energy released is the same as the gravitational potential energy, meaning the net energy is zero. No, it is not correct. Nobody postulated an unchanging volume. Rather, new space is being created.

Somewhere along the infinite scaling up of 'pocket universes', groups of pocket universes, etc.. there must be a scale at which the pattern repeats. Quantum physics, constructed of bits with uncertainty and field characteristics. A multiverse acting like a wave function underneath a universe that's part of a much larger multiverse. it's not like there's a limited number of arrangements possible as long as we're considering an infinite production of universes. How big would a multiverse have to get before it becomes a singularity? Or, at least a rapidly inflating one?

To say that there are an infinite number of pocket universes, while not being incorrect, doesn't really give an expletive to what the theory really predicts; if accurate, which I think it is, eternal inflation predicts that an infinite number of pocket universes are being created for every increment of time in which reality exists.

Thanks for presenting these interviews with Alan Guth. Inflation can explain a lot. At the time when mass and gravity appear, and large masses are accumulated, the mass that is no longer within our visible horizon could have had an influence on the mass within our horizon through gravitation. Isn't this a possible source of what is now described as "dark energy"?

I understand the inflation keeps going. I dont understand where the new matter comes from. If these so called pocket universe's continue being created for infinity, does the matter in all of these extra universes come from separate big bangs? Or was it it created in the initial universe? No one explaining eternal inflation explains this. Was infinite matter created in the initial big bang?

IMO the universe created us so that it can observe itself We could be the only iteration of life that exists that is able to discover, measure and document our findings I mean, it took 2 massive mass extinctions for humans to end up as the dominant creature LIVE LONG AND PROSPER

Why couldn’t the beginning be a black hole that at certain point reaches maximum size and density and boom. The expansion may be coming out of the black hole or something similar, not a tiny tiny point.

If you put 2 mirrors facing each other, you see the other mirror reflected and it goes on. Is it infinity?

Each time the image is reflected, a few photons are absorbed, making the reflection a little dimmer, so that it contains no photons after a few thousand bounces.

A "perfect mirror," one that reflects 100% of the photons that strike it, exists only in theory. Even the best mirrors absorb some photons.

Veeranna A.Y . Haha i just asked the same question. It does sound like the “pocket” universes are really the branches of the fractal ? The fractal is a copy of the whole so idk how to explain how each new pocket universe could be different (Peter Parker with blond hair) than in the next assuming the universe is infinite ?

Who could be more significant than those who understand so much that they see themselves as insignificant because of it? Every other material body in the visible and the invisible universe don't have what we have i.e. knowledge and awe at the utter vastness of what we can see and what we can't see. Heck, if we are alone in the universe then we are the only things that an see it. If we are insignificant, then everything in the visible and invisible universe are also insignificant, from the largest of stars and galaxies, to the smallest of atomic particles. Which would mean that the visible and the invisible universe itself is insignificant.

Meanwhile I have heard him say in a later interview that the new estimates are far less dramatic and the unobservable universe is “only” maybe a 1000 times larger than what we can “see”... so I imagine you should take everything with a pinch of salt. I mean these people are incredibly smart but that thing they are trying to decipher is infinitely more incredible than their considerable smarts 🤷🏻‍♂️

How long did it take for the universe, if time was slower right after the start of the universe? For us it took 10^-37 seconds. But how long did it take from the perspective of the universe? If space is relative, time is too, right?

This interview is captivating, though a bit outdated. Alan Guth explains his calculation of the size of the universe ... a guess based on twice the minimum (100 doublings x 2) during inflation. In a more recent interview (How Did the Universe Begin), Guth states the size of the universe is likely exponentially smaller than he previously thought (10^3 rather than 10^23 larger than the observable universe). Also, a brief discussion of the multiverse, and his belief that there may be an infinite number of pocket universes. BTW, the interviewer (Robert Kuhn) incorrectly states the diameter of the observable universe is 40 billion light years. In fact, it is estimated to be 93 billion light years (with a radius of 46.5 billion light years).
