Multiverse or Universe? - Andre Linde (SETI Talks)
About | Information | History | Online | Facts | Discovery
SETI Talks archive: http://seti.org/talks Cosmological observations show that the universe is very uniform on the maximally large scale accessible to our telescopes, and the same laws of physics operate in all of its parts that we can see now. The best theoretical explanation of the uniformity of our world was provided by inflationary theory, which was proposed 30 years ago. Rather paradoxically, inflationary theory also predicts that on a very large scale, much greater than what we can see now, the world may look totally different. Instead of being a single spherically symmetric balloon, our universe may look as a "multiverse", a collection of many different exponentially large balloons ("universes") with different laws of physics operating in each of them. In the beginning, this picture looked more like a piece of science fiction rather than a scientific theory. However, recent developments in inflationary cosmology, particle physics, and string theory provided strong evidence supporting the new cosmological paradigm. It changes the standard views on the origin and the global structure of the universe and on our own place in the world.

Genius.. fantastic lecture... I think they're on to something with this eternal inflation.. such a shame it's so impossible to test.... however, I'm warming to the argument that says we don't need to make predictions to test for multiverses- because the anthropic principle essentially says that the only test is to see whether or not we find ourselves in a suspiciously well tuned universe or not :)

I want too see more Russians like him, very proud!!!

we think our life 80 years is a long time. we think a light year is a long distance. we think 'half a pulsation' (bing bang to 'now') is a long time too. well the big bang exploded from a dense point, size of a marble etc., well what compressed it to that point: the compression half of a simple pulsation. we - finite us - are in the explosion side, now, of the explosion out again, in out in out in out. we just don't like looking at a few hundred billion years as say an expansion side of a pulsation. : whoop de do, we're so special that we can't look at it as what it is, an uninteresting pulsation in a it's-not-relevant-as-all-is-infinite part, point, prosaic subset of Infinity.grow up, kids. try to grasp infinity for the first time, in your miserable self awareness and 'I hate being finite' predicament. get drunk to obfuscate the facts

so really, black holes are universes in the making, if you could detonate a black hole that would be the same as explosive, if you removed all the gravity at once

Why are people who are so brilliant in cosmology so stupid in social matters? The sentence "there is no such thing as a free lunch" ist neoliberal propaganda and nothing else. Without knowing it Mr. Linde propagates a "theory" of economy whose apologetes have got every lunch in their own life for free. To say "there is no such Thing as a free lunch" was an apology for marking People poor and hungry! Free lunch in a free multiverse!
And i am not sure, if static mathematic and physic are the best of all possibilities for life and intelligence. A world in which static equation like 2+2=4 are onlyare Special case of 2+2=2 or 3 or 5 seems to have a greater potential than our static and stupid world. -

The basic principles of Platonic physics as of 9-10-2014
Roger Clough
1. All of the principles of Leibniz's Idealism, especially those of his Monadology, apply, in addition to the
principles stated here. If you do not completely understand the Monadology, you may misinterpret
what is said here.
2. The universe consists of two completely corresponding, entangled realms, the mental, which is alive, subjective and causative,
and the physical, which is dead, or essentially so, objective and passive.
3. The physical world is the world of spacetime and consists completely of bodies of matter (the physical)
so that space does not exist other than as perceptions in memory of the relative positions of all of the
other monads in the universe.
4. The mental world consists completely of Leibniz's monads as defined in his monadology,
except for the the highest or most dominant element, Plato's One or Mind, which has the universe as its monad..
5. The monads are quantum waves.
6.. All causation is mental and top-down and obeys Leibniz's pre-established harmony, which ensures
the best possible or least conflict among moving objects.otion .
7. Since the highest mental element is Plato's One or Mind. all causation and perception ,
directly and indirectly, is by the One.
8. The One is mental and timeless and contains, as part of its permanent memory, all of what Leibniz called necessary ;logic.
9. The physical correspondent of the mental is the world of spacetime and obeys the usual physical laws of
science including, to a certain exgtent, Newton's laws, and Einstein's laws of relativity.
10. The preestablished harmony has as its output the harmonic motions of objects in the everyday spacetime world of physics.
11. The physical world is the physical, spacetime world of science and experimentation, but is perceived by individuals as phenomenol,
meaning from only one point of view.
12. Since the physical world of spacetime is completely made of matter and force is not matter, force,
including the four principal forces, is a mental component of causation.
13. Thermodynamics, as well as all physical laws, are the mental rules of conduct of material bodies.
14. The universe is cybernetic, in which the One is the singular point of perception and control of the Many
physical bodies in the universe, just as a monarch controls his kingdom..
15. As such, there can and must be only one of the One.
16. Perception is the conversion of the physical, by the One through its monads, into experience and memory
by the One.
17. The physical world of spacetime and its physical objects, was made by the explosive creation of
physical objects from Plato's Mind into spacetime.
18. Life was also created at this time.
19. Intelligence is ability to freely make choices.
19. The One has the free will, within the constraints of the pre-established harmony,
and the intelligence and Mind, such that it is identical to Life.
20. Thus the universe exploded out of Life.
21. The basic characteristics of monads are given in Leibniz's Monadology. They are
sets, I surmise, in the mathematical sense of complete concepts, are alive, and are
nested to an infinitesimal degree. Much more is said of them in the Monadology.
If you do not completely understand the Monadology, you may misinterpret
what is said here.
22. Each human being is a complete concept and so is a monad containing other
monads, the principal one of which is the small m mind and its neurons.
24. The brain is a passive object completely controlled by Mind.
25. Each neuron is a monad.
26. Human perception occurs as input sensory nerve singles in the brain
are transformed by Mind into quanta of experience.
27 The awareness or apperception (to use Leibniz's term) of these experiences is called consciousness.
28. Since Mind is time-invariant, consciousness consists of changes in Mind, of a ordered
set of perceptions similar to the sequence of frames of a movie. But the brain
actually perceives such sequences as it would a movie.

Why is it necessary for an universe to start with a few milligrams of matter???

According to what we know now, the space-time itself was created during these larger or smaller big-bangs. In that case what exactly is between those balloon Universes?
We can conveniently draw them on paper and we can see the distance between them. What exactly is between them since space is created separately for each of them?
Does it imply the existence of an absolute space and of an absolute time again? -
YT Search for The Principle Documentary, opening in October in Chicago. It is highly relevant to this.

Excellent!

The inflationary model has not been proven right yet by observations and there are competitive models like the Cyclic Cosmological Model. Although there is consensus among scientists that the cosmological model with Inflation is correct. However without observational proof, the consensus regarding the Inflationary Model can lead to the fallacy of "Argumentum Ad Numerum", the idea that something is true, just because great numbers believe it. But this is science not politics...
What is more, BICEP II data interpretation seems to be incorrect. Hopefully LIGO, LISA or others observational experiments will soon detect (or not) gravitational waves from Inflation leading us to confirm the Inflationary model or to discard it. -

I don't understand why this guy states that it's "stupid" to ask when the Universe began... How can something have no beginning? Since when is questioning something idiotic? Isn't that the whole premise of Science? From various sources I have studied that Science is on the track of answering such questions, but is still far from an answer: just because we have equations saying something theoretical like the universe has no beginning (which we cannot prove) doesn't give anyone license to call any question or those asking the question "stupid". Furthermore how does throwing the concept of a multiverse at the general populace satiate the question of the origin of the universe? I've read alot of claims that the multiverse theory could be the beginning to explaining the origin of everything we know, but that once again raises the question where did the multiverse come from. I do not understand how you get something from nothing without some force applying an effect or intent from an external perspective... and once again where would that force or intent originate from? Based on the total sum of what we know about the construct in which we live, deeper thinking is an absolute must, how can we keep banging our heads against the wall stubbornly insisting that the causality of everything is merely an accidental emergence from some infinity which has always been. So are we accepting that the reality in which we live is an infinite organism? If so, is this organism cognizant? Does it exist on a lower or higher scale than we can perceive? I know for a fact that these questions have been asked before, yet the always get lumped into a category of religious zealotry and the questioner gets compared to an imbecile. But seriously, IF we can't understand our past in totality, do we truly know who we are? I'm always wondering about these questions.

the real departure from wave mechanics to quantum physics took place abruptly in the summer of 1911.....werner Heisenberg,wolfgang pauli and and max planck were all working a second job in a ships boiler room ..to make ends meet..and fund their research---times being hard that year.....also Edwin schrodinger and einstien were assigned to the same ship by mistake...but einstien and schrodinger got the good jobs as supervisors and palnck and his boys got the hard labor--shoveling coal...it all came to a boiling point...planck was growing more resentful of shcrodinger each day..and when he learned that madame curie would be staying in schrodingers cabin...it came to fist-a-cuffs....see the actual film footage --of that momentous day in physics and romance...see link below..at time...46:11

If the Universe is like a fractal then parts of it will bump with each other? Can we detect that?
Why Inflation happens? Something is causing it, right? -
