Cosmic Inflation and the Accelerating Universe - Part 1

[Nez949]

I believe it was not a big bang for our universe; ours is the result of a "Big Divide" of one Universe into two, and I believe the sudden acceleration is the result of our universe starting the process of Division again. :]

[universalsailor]

Only a handful of people in the world understand this topic since it requires a grasp of at least undergraduate physics / math to acquire even the basics.

This obviously disqualifies everyone else from discussing the matter meaningfully, but as we see here, it doesn't stop them doing just that.

So it goes.

Exercise your right to disregard the unschooled.

Mention universe and bam, you got a religious debate in the comments section!

The big bang and inflation

According to brane theory two branes touched or bumped into each other at a point and this was the singularity of the big bang.

However if we think of these two branes continuing to contact at an increasingly larger radius moving at a rate greater than the speed of light would this not explain how inflation occurred?

What if these branes are like soap bubbles and our universe is the contact surface of these two bubbles?

[ibizarise]

Evolutionism is a dangerous religion

[Jspeterson]

Very Guth!

[coreygames]

@Jspeterson Nothing created the Universe. No magic possible in the beginning to start the creation. All myths are lies: creationism, afterlife etc.

[alexrj2]

God created the Universe. No energy possible in the beginning to start the big bang. All theories are lies: big bang, evolution etc.

[Jipzorowns]

@alexrj2

how are all theories lies? If these "mathmatical" theories are incorrect; GPS would not work, the internet, your mobile phone should not work. they are based upon these theories (not so much the big bang itself, but the big bang theory came forward out of these mathmatical theories)

[alexrj2]

@Jipzorowns NO. I SAID THAT EVOLUTION IS A LIE... MATHEMATICALLY IMPOSSIBLE.

AND ALL THOSE TOYS YOU MENTION ARE TO CONTROL PEOPLE AND MAKE THEM

BLIND.

[Jipzorowns]

@alexrj2

okay, so proof, show us that evolution is mathematically not possible :)

[alexrj2]

@Jipzorowns i have already done that, read the others posts. trillions of changes in millions of species, simple: impossible.

[Jipzorowns]

@alexrj2

right, so good luck on that! You won't mind show me the mathematical proof then? you do realize that other species and other universes did came from this big bang or other big bangs? You do realize that evolution is not only here on earth?

[alexrj2]

@Jipzorowns did you think about the impossibility of so many changes in so many species? juste impossible. i dont believe in evolution at all, i believe that God created the earth and all the species.

[Jipzorowns]

@alexrj2

it's possible, with all the random dna mutations, that created many different species over billions of years. You can actually see, how different species have grown. Compare one animal to another animal you will see how look-a-like they are. You should study evolution, instead of having no valid arguments. Or you should show me the mathematical proof then? No you won't, because you don't have it. You ignorant prick. "We" thinkers, who think. Come way futher than you people.

[Jipzorowns]

@alexrj2

Instead of looking in a book and take everything for granted. Start exploring, damn. The earth is older than the bible says. And look back in the past, they first thought god created the earth and that the rest was rotating around the earth. Now we know that is not the case. Big thinkers have searched for answers. And also found evidence evolution. There more evidence for dna mutation, than a god on a cloud, with a laptop, keeping scores.

[alexrj2]

@Jipzorowns there's no evidence that the Bible is older than 10000 years. a lot of videos that you can find here about how old is the earth, see the videos of bereanbeacon.

[Jipzorowns]

@alexrj2

wtf h@H@ you are so dumb. I never said how old the bible is. open your eyes please, small minded fuck

[alexrj2]

@Jipzorowns i meant life in described in the Bible. dumb is you and your minded that is controlled by satan...

[Jipzorowns]

@alexrj2

no, YOU are the dumb one here. I am exploring the possible options. I truly want to know. No magic man in the sky. Because there is no true evidence for it. I have nothing against religious people. But c'mon dude. Explore your options, try and search for how it truly is, and not how it should be. I mean, I want there to be a god, but you cannot prove it! I believe the evidence that is given, about the existence of the universe, if "god" is proven, then I shall believe ;)

[asherasator]

@Jipzorowns The Big Bang Theory was invented by Georges Lemaitre a Roman Catholic priest & physicist. It's nothing more than creationist physics [1 biblical day in some beliefs is millions of years], ironically evolutionist & atheists use the theory yet don't realize simply believing in a big bang is giving into creationism in technical jargon. Einstein believed in a "static universe" & had nothing to do with the big bang, which is a Roman Catholic invention.

"The devil is in the details".

[asherasator]

@Jipzorowns The only reason the big bang caught on was it harmonized with many peoples inner feelings of science & religion & unified the 2 belief systems. There's always been a high population of people from religious backgrounds or families that enter physics. Big bang being of [a priest's] theoretical physics explanation doesn't go against religious spiritual beliefs & practices. It gives em a footing in the modern world. Most big bangists don't realize they're under Christian influence :)

[arch37]

The Bible says the earth is around 6000 years old! Now how does your theories hold up to this fact? Only self righteous people leave Jesus and God the Creators of life out of the picture! Nincompoops!

Humble your selves in the hand of God and He will lift you up! It's not you trying to put two and two together in your own wisdom that figures it out, but Jesus sharing with you as a friend! How would you even begin to know what happened billions of years ago. It's too mind boggling!

[grzymol]

ledzeppelin2131 - the inflation theory is so promising precisely because it predicts creation of the universe out of virtually nothing, listen a bit more carefully. Secondly - my little cat at home usually hides away when he hears a thunder. For him it poses imminent danger as he is for himself the centre of everything. Let me be civilised and say only this - if you seriously think that the whole universe in its all grandeur was invented just for you to feel important - well it is so childish

[stopdemockery]

If the universe is expanding at the speed of light, explain why the stars are in the same positions as they were thousands of years age. The constellations are the same, why?

[hexidecimalAFF0]

@stopdemockery Hi, I want to clarify this to you as why the constellations are the same. It is the galaxies in the universe that are rushing away from each other, not the star systems in the Milky way, therefore in the near further, the only stars that will be viewable is Milky way star star systems.

We will be all alone in the near further and in respect to movement, our lives are very short, so it's not possible for one generation of humans to make dicernible comparisons.

[MrFyrfly]

The only "evidence" for inflation is nothing but theory. They admitted there's no solid evidence.

[FeelOfFriction]

Quit clear cutting the rain forests.

[hackenbollox]

@maxwellsdaemon7

NO. The space between them is expanding, so the distances are as well. The balloon analogy is apt, because the points are still occupying exactly the same space on the balloon, but the space between them is growing.

Not sure why this comment was marked as spam.

[hye384]

so inflation theory is an explanation of why the universe is expanding?

[couerl]

To sum it up, inflation describes how the universe got so large (infinitely large) in 13.7 billion years time and more specifically during the first second or so of the universe's existence to begin with.. During the first second of the big bang, the current laws of physics hadn't been "born" yet and so it was theoretically possible for the universe to expand faster than the speed of light for a very brief instant, because at that time there was no universal "speed limit".

[VannevarBush]

@couerl

The expansion faster than light actually does not contradict to the theory of relativity. What expands there is space itself. In relativity it is stated that /group velocity/ must not exceed the speed of light. But this is not required for the phase velocity. Talking about the expansion of space refers to the phase velocity, I guess.

[VannevarBush]

@VannevarBush

add-on:

When space expands there is no travelling of information so-to-speak, meaning that there is no need for that speed limit.

[infinitenight2093]

hye384-

no, inflation theory is just an explanation of how the universe could have grown to such an immense size in a small amount of time while keeping its density the same.

WHY the universe is expanding is another topic, and that topic is called dark energy (the energy of the vacuum)

[BigNewGames]

I am confused, if the universe is only 13.7 billion years old then why did HST UDF image old galaxies 13, billion light years away? If the light is just now reaching us shouldn't we be seeing dust and stuff, predicted early universe, not old galaxies, OG, clustered together closely? Then wouldn't the whole universe be much older than that & the Milky Way is just much younger than those galaxies? How can the light now be reaching us & show OG? Why are those OG moving away at nearly the SOL?

[Kainspear]

Inflation I believe is not the best theory for the expansion of the universe, because the obeservational evidence is poor, I believe in the VSL or varying speed of light theory that explains the expansion of the universe but is subsequently different from the inflation theory, look it up it makes more sense in my opinion.

[Madrrrrrrrrrrr]

Hahaha. If you listen closely he actually describes VSL

[FeynmanMH42]

Alan Guth makes inflationary theory easy to understand, but there are a few things I don't really understand that this video doesn't mention. Can anyone help me understand what scalar fields have to do with inflation?

[Calculusman08]

It's okay if you don't understand Guth. He was actually wrong about Inflation. If you want to message privately, I can explain the scalar fields and their correlation to Inflation if you like.

[southernCal909]

The force accelerating matter, is the Cosmic Inflation itself.

[rhinopod]

These dates have no foundation. Was there hydrogen at the big bang or was there the heaviest elements ? FACT: something does not come from nothing and life does not come from non-life. The universe accelerates, if so, then because F=ma we can ask this rational question; What is the force accelerating the matter ?

[armcon3012]

hydrogen and all came after inflation.

energy is yet to confirm as dark energy, the energy 'soup' of universe. In the realm of 'false vacuum', before symmetry breaking, F=ma does not apply as yet. Forces are more gravitational ie spacetime warps and quantum fluctuations

[Maracachucho]

repulsive gravity, according to the general theory of relativity (as far as i know it), makes matter "produce" space, meaning that this repulsion is caused presicely because space is curving away from matter.

[Wcoltd]

Why do we use the term "Dark energy" as a parameter to describe the expansion? if the distribution of Dark energy is homogeneous, why isn't the expansion described as an inherent character of distances.

[PeshwariNaan]

I can't concentrate now.

[WisdomVendor]

I aaah, couldn't aaaah watch aaah all of this aaah video due aaah to counting 20 "aaahs" in the first 1 min and ahhh 17 aaah seconds. It was aahh too aah annoying.

[starrynightuk]

undoubtedly less annoying than you

[milesp0123]

Your comment says a lot of about you, "wisdom" vendor.

[ledzeppelin2131]

I agree, physicist should focus in studying the vaccum energy.

[ledzeppelin2131]

Creationism is a nonsense literal theory that was taken from the bible. The fact that there is a creator dosent have to do with creationism.

[ledzeppelin2131]

In order for life to be possible as it was the big bang would have to have been at a perfect speed of expansion, otherwise nothing would have ever been formed the way it is.

I dont really think Guth beleive in creationism but the study in inflation open the door to the beleive in a God. He is not refering to creationism anyway, but inflation points out to a creator, whatever the meaning of creator is it dosent have to do with creationism.

[BrunoTheQuestionable]

The same can be said of most of the fundamental physical constants, which seem to be fine-tuned to produce a universe which can support life. The anthropic principle proposes that they must be so or we wouldn't be here discussing it. Hopefully when the "theory of everything" is completed it will predict most or all of the physical constants that we observe.

[ledzeppelin2131]

I dunno anything about cosmology but I think that in that case there would be some remaining energy and matter prior to the big bang, but for what we know everything came from the big bang but I could be wrong.

[BrunoTheQuestionable]

What I would be looking for is a theory which allows for the spontaneous appearance of the universe from nothing. The properties of the quantum field would account for the big bang and everything that follows.

[mytubecomment]

Sounds perfect to me.

[BladedArrowTBGamer]

@BrunoTheQuestionable you do know that there might be more then one universe "(which would then have to be called a multiverse) and the only way to have a universe that can be examined by life is a universe that can support life so saying "oh wow look were in a goldilockes zone so it must have been God" if we werent in a goldilockes zone we couldnt be examining said universe anyway so your comment is redundant

[lourak]

@BrunoTheQuestionable Why would you limit your inquiry in this way? As for the so called "quantum field" - well - that is far from NOTHING, despite the popularization of of the notion that it is.

[ledzeppelin2131]

Alan Guth stated that If the big bang would have been some thousandth of a second after the moment it was, that would have caused an eternal expantion and it wouldnt have been possible the creation of gallaxies and stars in the universe.

On the other hand if the big bang had occured in some thousandth of a second before. the universe would have had an inmediate and total collapse.

[AscendentInLeo]

don't belive him.

[mazdaplz]

don't believe who?

[SardonicusRexx]

Uh... but why?

Needs Carl Sagan to translate.

[whiskynwhisky]

its alan guth pretty much who came up with inflationary universe theory.. he just incredible .. inflationary theory explains so much about right after the big bang more it does really provide big bang with the bang.. well i wish we could find more videos of him on the net..

[DickJohnson3434]

Ever hear Kent Hovind talk about Guth?

[tiove]

is it some sort of dumb christian?

[DickJohnson3434]

Hovind? He's a creationist who's now in jail because he didn't pay his taxes. His argument to the judge was "I'm bankrupt, these millions of dollars belong to God". He makes fun of Guth in some of his creationism lectures.

[tiove]

lol yes i just read about him on wiki and shocking how he fasely declared bankrupcy he was also charged with assualt but his employee dropped charges. why does he make fun of Guth what about do you know?

[thematrix606]

Nice vid, who is the speaker?

[BrunoTheQuestionable]

see description

[thematrix606]

Ah lol, im not used to youtube xD
