The Great Photon Escape

- In a flash known as the Big Bang, our universe was born. Yet for hundreds of thousands of years, light from the Big Bang was scattered and trapped in a dense fog. Eventually, though, that light made its “great escape” and the universe was plunged into total darkness. These cosmic “Dark Ages” lasted for millions of years until the first stars and galaxies burst to life and began to illuminate the universe. However, no one knows just when this happened or what the earliest stars and galaxies were really like, because we’ve never seen them.
NASA’s James Webb Space Telescope, currently under construction and due to launch in 2021, will use its powerful infrared vision to spy the very first stars and galaxies forming out of the darkness of the early universe and help us understand how today’s universe came to be.
This video is produced by the Space Telescope Science Institute’s Office of Public Outreach and is narrated by Alia Shawkat.

Great explanation and a really nice voice. This will be a great channel to keep up with. I subscribed.
Absolutely brilliant video and this voice her.
wow, I understood a great deal of this, so thank you for a concise and very well organized presentation (oh, btw, the James Webb telescope can't possibly work, gonna be a big flop, will never deploy properly that far out - ok, now I'm preparied, willing to be pleasantly surprised)
Surprised yet? Pleasantly?
Really enjoyed it. Thanks.
I'm trying to follow what is being said but the music is really distracting.
'The Great Photon Escape' I.S.:
The most coherent presentation of the Creation Process.
And the escaped Photon I.S. the STAR of the shaw of ALL the Baby Bangs!! Where all things begin.
From beginning to NO end. 010 Uni-Verse.
Friend Edmond, this Great Escape is a part of the Big Bang, a result of its occurrance. She mentions various timings: 300,000 years for the CBR to be created and so on - those timings all date from the Big Bang. There is only the one that we have observational experience with, though that doesn't rule out others. There is both a beginning and an end. Poetic extrapolations sound fun, but they are misleading, particularly to someone who doesn't know the science.
I'd like to ask a NASA scientist to theorize why photons travel at the speed they do. And whether the initial ejection of them is connected to their speed. Can you slow a photon down so that it just hangs about? If you can, and then release it, from whatever force you used to stop it, what makes that little guy take off? Where the heck does it think it's going? Sometimes it's hard to believe you can change their direction with them bouncing off of a bedroom wall.
sclogse1 yea , why is a photons natural state moving at the speed of light ?
Just in case you were still wondering three years later… Yes, photons can be slowed. Light travels slower through water.
I guess they travel through space at the speed of light because they are light. They are bent by gravity, as in gravitational lensing.
Great video 👍
Hard to believe we have the technology and ability to read temp. differences that incredibly small and that far away???
Yup. Specifically, we have satellites, but I have to clear up one misapprehension. We're not seeing heat generated from far, far away, we're seeing the light photons released into the dark universe when it rather suddenly went transparent. It is that light we are seeing, red shifted from light frequencies, through infrared down into the microwave spectrum segment - it is radio waves, not heat. It equates to black body radiation of a body at about 2.5 Kelvin. The temperature variations map to the whole universe, near and far, as seen from Earth.
I love her voice
Marry me
This video is awesome 👏
really great. Alia Shawkat looks like Emilie de Ravin from Lost! doppelganger??!
Brilliant video
Awesome explanation.
thank you for this great video!
Little slow at the start, got together greatly later!
So was the universe
Galaxia ll9i9988
I ♥ this vedio.
mfw the hubble space telescope has it's own youtube channel
Brilliant!!!!!!!
Source of light..?
alia shawkat? awesome
James Web is over 83% of the way to it's L-2 Orbit.
laberda que se miran cosas muy buenas los felisitos sigan adelante
Great information thax
If "soon after the universe was born it was plunged into total darkness" does that suggest there was light before the big bang - before the universe was born? From what source would this light emanate?
+Wayne Turner 1. Scientifically, there is no "before" the big bang. The big bang was the creation of space-time. The "before" you speak of is a philisophical point.
2. The universe went from totally ionized to darkness. Imagine ionization as trying to look through the sun to see what's on the other side. It went dark once the universe expanded enough to let photons escape, yet there was nothing around to produce new photons yet.
I sped the video up to 1.25 to make it sound normal.
+qqqqq qqqqq In that case, the English vocabulary seems inadequate to describe such events. The word *plunged* is the past tense of *plunge* inferring it happened after some other event - i.e. the birth of the universe. Maybe I am that I am would be better? :-) Personally, I find it fascinating that science pushes the boundaries of understanding in many disciplines, including language and metaphysics.
+Wayne Turner After the Big Bang the universe condensed into light (photons), electrons and protons (matter). The light was trapped in the dense universe until it expanded enough and cooled enough to escape (after 400,000 years). As the video explains, after that light escaped, the Universe was "plunged into total darkness."
+Joel Green Into what did these photons escape? Was the universe expanding at sub-light speed when they escaped? Was light able to travel beyond the confines of the universe? If the big bang created space and time and light is able to escape these dimensions then do we need to define another dimension bounded by energy?
+Wayne Turner Yes, the Universe was (and still is) expanding at sublight speeds, locally. But because of cosmic inflation (the faster-than-light expansion during the early fraction of a second after the Big Bang), much of the Universe was already out of contact with other parts. The observable universe is defined by the bounds of where light can reach us from, and it's the only part we can do experiments on to determine nature. Beyond that horizon, we can't know and can only speculate, so we can define parallel universes or other boundaries and no one can prove or disprove it otherwise. (Unless we discover new physics, of course.)
but that electrons ann photons ... they were there since ever
someone qualified explain me pls
the past should be finite otherwise nothing never happend!!!
and if u can link references, it would be amazing and useful :)
i glad the find this video :D
I find it amuzing and annoying how the photon particles in the animation move slower with temperature and they change direction randomly
Hahah it’s Maeby Fünke!
THIS VIDEO IS A TOTAL MIRACLE. THANK YOU FOR THE VISION! GOD IS SO HERE.
Wow a scientific doc showing the temperature in F. That's a bit off.
A hard life, I suppose, for metric-only sorts. Perhaps you need to go bi-caloric.
Naw, I'm pulling your chain. I agree the only way to shove the "King's units only!!" body politic to where it needs to go is to keep goading it when it turns insular. So goad on.
But It is only me that wants to know how Webb survive to all posibles crashes with asteroids, ect. durant travel?
What has Durant got to do with this. Hahahaha.
"C" is an infinite velocity which is instantaneous. By this I mean a light turned on, on one mass body will be seen immediately on any other mass body regardless of its distance from the source, be it twelve miles or twelve billion light year miles in distance. The light we see in any form or frequency from those distant galactic sources are occurring at the exact moment of their creation. It is we who put time constraints, based on our values, on when this light or frequencies were created. We are not seeing things as they were ten billion light years ago, but as they were happening a moment ago. .
Perhaps looking at it from the perspective of the photon isn’t so useful. It seems to make more sense to see it from our point of view, given it’s us who experienced the time passing since the photons were emitted.
Marry me!!
I've made a huge mistake....
Photon is obviously somewhat charged particle or how else could it valence an electron? But before any matter whatsoever when God looked upon face of the deep, what was sort of light used to make the deep appear gray? The gravitational wave fielded echos must have intersected when space was created. Very little Universe proportion even today travels the minority direction.. Universe's radial start-off area has to be nearby one of the outer boundary firmaments.. When you don't study and observe to think, love, hate, for your own reasons, then you become sheeple like "The Double" in 1 hour 30 minute movie or Bertrand Russell biographical film "Why I am not a Christian " atheist, instead of freedom thinker like non-religious Gentile aliased Faithman like Jesus Christ human who rules heaven pertinent to himself, beside Mary Magdalene who does same.
Ok
i On,
The I is for an Instantaneous speed of Time - ON.
Intangile = Tangible Uni-Verse in Micro-Second.
0s and 1s - On and Off.
Forever
maybe there was no big bang. maybe the universe is infinite and eternal.
The power of God, was the one who put this so on point universe together, no other way but to know for a fact that God for a fact said let there be light, it goes perfect with all the light talk, and darkness talk.
What about before that, God made the big bang so he could get shit done faster? Why are you even here spreading your bullshit. It would be like me going to some God videos and make comments about how the earth is not 6000 years old. People would ask me the same questions.
DARKNESS/ YOU MEANT NO LIGHT FROM THE STARS?
GAWARZM BASRY There weren't any stars yet. The matter (mostly hydrogen) needed to condense first and form them, thus the "re-ionization"
Astronomers "think:"..... they are not good at it :-)
MaşaALLAH.
"And God said, let light be made, and light was made."
Fuck off
+tommie293 What bible is that translation from? It doesn't sound very majestic. If you are going to make a youtube post that is going to exist till the end of time, you should try to make them of better quality. This is very uninspiring.
wow I didnt hear him say that, musta missed it. And while we are on the subject of God 'He' must have had a heckuva jacket to be protected from that heat/cold. Actually I would have to say WE are the gods for figuring this timeline out. Why did it take him 13.7 billion years to send Jesus to do some sleight of hand and create urban legends? Oh wait, he has to make the rounds of all the gazillion planetary bodies, that takes time....or do you think we are the only ones and he made the universe so we could say ooh and ahh? Keep the faith brother!
The universe is only 6000 years old. You believe it is billions just because they say it is? They say carbon decays at a constant rate but how do they know when they can't watch it decay for a thousand years. It is all a bunch of made up fairy tales to keep people believing it so God has a way to really test their faith. God can only take 600,000 people with him to the heavens so he must test everyone to weed out the bad apples. Heaven will be wonderful. It will be filled with coke and hookers and plenty of rock n roll. I wouldn't mind a few golf courses and how about some good wifi. Can you do that for me Jesus? Don't fuck with me now. Also ask God what he is going to do with all those babies that died when they were a week old. Surly he can't send them to hell. They didn't even have a chance to sin but I don't want a bunch of week old babies in heaven annoying me when I am playing golf with hookers. They are also taking spots from my friends who I told there would be plenty of coke there. Fuck I have to rethink all of this. It is starting to sound like bullshit. I will be pissed if I get to heaven and I get fucked. I better go fuck all the hookers I can now just in case. Good thing I read the comments.
I am surprised civilization survived with kooks like you in it...with all due respect.
3. And God said, Let there be light: and there was light.
(Genesis 1:3)
)
God said but who did?
Why do you even come here to post? Go back to your bible. Or you think you are spreading the word of God? LOL Well when I post on bible chats that Adam fucked Eve in the ass I guess I am spreading the word of Satan. I will make sure to tell them Andriy Chmel sent me
A creator
God's amazing light exploded about 18.6 billion years ago, which was probably not even the only cosmic event that started way back in the beginning of time.
13.772, I believe. God is such a card.
