The Great Photon Escape

Ғылым және технология

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.

    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.

    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'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.

    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.

    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?

  • @joelgreen1748

    @joelgreen1748

    +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.)

    "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.

    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.

    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.
