Inflationary Cosmology: Is Our Universe Part of a Multiverse?
Inflationary cosmology gives a very plausible explanation for many features of our universe, including its uniformity, its mass density, and the patterns of the ripples that are observed in the cosmic microwave background. Most versions of inflation, however, imply that our universe is not unique, but is part of a possibly infinite multiverse. Guth talks about how inflation works, and why he believes that the possibility of a multiverse should be taken seriously.
About the conference:
Physics@FOM Veldhoven is a large congress that provides a topical overview of physics in the Netherlands. It is organised by the Foundation for Fundamental Research on Matter (FOM) and takes place each year in January. Traditionally, young researchers are given the chance to present themselves and their work alongside renowned names from the Dutch and international physics community. The programme covers Light and matter, Atomic, molecular and optical physics, Nanoscience and nanotechnology, Statistical physics and Soft condensed matter, Surfaces and interfaces, Physics of fluids, Subatomic physics, Plasma and fusion physics, and Strongly correlated systems.

I cannot help but comment on the plethora of idiots who have posted abysmally ignorant comments on this lecture - or other lectures of equal substance that I have viewed on YT. Please give the likes of Alan Guth, Andrei Linde, Lawrence Kraus, Steven Weinberg, Leonard Susskind, Paul Dirac, Robert Dicke, Jim Peebles, George Gamow et al, a semblance of intellectual approbation in what they have contributed to cosmology, and the nature of the Universe. These few, these happy few, this band of brothers - among many untold others - are the Gods of Mount Olympus. Zeus be praised!

Guth astonishingly explains what is possibly the central inside of a black hole that is big enough to actually be volatile enough to eventually create that "small zone" of repulsive gravity that is big and strong enough to push the whole thing apart (means actually to produce a "big bang", that creates a new universe using the fluctuating energy it starts to convert into actual protomatter and lateron matter). Means: black holes that are observed throughout the actual universe are way too small enough yet to be that "unstable".But have some fluctiations inside of them already which are within the closed-boundary parameters to not obliterate the whole thing. A good indicator of such is the already observed "hawking radiation", showing it not being entirely stable.

@pieinskee3524

don leavell Perhaps, but I don't think it's reasonable, just because a theory involves inflation, to claim every other inflation-like event as corroboration. Guth basically makes the fact of the acceleration of expansion, his own purely on the strength that you could call any radial acceleration 'inflation'. But this is fallacious (not saying deliberate), does he claim blowing up a party balloon as an aspect of his theory? The acceleration of the universe has to be assumed a totally different underlying dynamic until someone suggest a theory - a whole theory in its own right - that these are different aspects of the same thing. And from that makes a non-trivial prediction that bears out.

+Jesus isGod Um, anybody with the title of PhD physicist, given the vast prerequisites for such a field, is automatically serious in my opinion. All the more better he campaigns against superstitious, religious nonsense. Jesus is God? I would read an Ehrman book for a sobering look into the origins of Christianity.

Dude, please don't troll for boys on my blog. You're obviously out of school here. There is no god. You've mistaken a conceptual spirit for flesh, dude. Please get a brain. I can't really understand how you've missed the world whirling past you. Get a life. Get a boy and enjoy yourself.

Thank you for your diagnosis. I've noticed that creationists are magically competent in all sciences, without knowing a damn thing about which they speak. And you're no exception. You're just an idiot screaming in the darkness. Sorry, man. You should get that checked out.

I'm not sure why inflation at multiple times light speed is better than multiples of light speed for expansion.
@mdjones4
@mdjones4 7 лет назад
So is it possible that dark energy is a weak form of inflation?
@Just.A.T-Rex
@Just.A.T-Rex 2 года назад
No. If this was the case galaxies showing dark energy ratios consistent with the their shape would also inflate between particles and this isn’t the case.

Imagine the universe didn't evolve from a tiny "partical", but instead, burst through a hole in the space-time fabric; a rip. In 3 dimensions of course, not a two dimensional plane. Like an explosion after the fabric rips. Where it came from I don't know of course. I keep having this idea.

The etymology of multiverse is confusing. Considering the actual definition of universe it is a flawed descriptive . This is one reason why , over time science ideology and theoretical modeling become convoluted and non intra communicable .

16:20 o if matter -hot dense soup of particles .. filled all space uniformily .....where is IT than expanding and cooling in to ? (another all space?) .......and why after 14 bln years of expansion=runaway from primal soup .....we register background radiation from furthests places of void we "travel" < - moving as cosmos grows (not only from much narrow area of primal density -before cooling and growth)

Fact; Proof of parallel universes is still beyond the domain of science.
@timblizzard4226
@timblizzard4226 8 лет назад
That is neither a fact, nor is it necessarily a well defined statement. First, define proof - if we developed a mathematical model of the universe which perfectly predicted the observed universe's observed history, and that mathematical model made multiple universes unavoidable, wouldn't that provide some level of evidence? Second, there are active research programs ongoing right now looking for evidence of 'universe collisions' in the cosmic microwave background data which, if some imprint were found, would be direct, empirical observation of other universes.

I wonder is it synchronicity that his last name is so close to Goof? lol his theories are dead, No big bang just mention NGC 4319 to one of these guys and watch em go nuts. If you don't know about NGC4319 research Halton Arp. See what they did to him for discounting their precious big bang. Allan Goof.
@thebaconized4733
@thebaconized4733 8 лет назад
Wow such an intellectual rebuttal. Alan goof and NGCwhatever number it was. Case closed!
@timblizzard4226
@timblizzard4226 8 лет назад
Arp's ideas have been soundly debunked by numerous papers in both astronomy and physics. Galactic redshift is not the only piece of evidence which supports the big bang. I don't know why trolls like you have to be so obtuse.

What a beautiful mind. Too bad he can’t devote 10 minutes to talking about the controlled demolitions of the world trade centre buildings. It would help the world immensely more than wasting time on this highfalutin stuff where out of touch zombies are kissing his ass. Same goes for all the other pop physicists like Carroll, Krauss etc who’ve made personal fortunes on the book and speaking circuit.
