The Afterglow of the Big Bang: The Cosmic Microwave Background

The Cosmic Microwave Background [CMB] is the oldest light in the universe that we can see or detect. It was emitted only 380,000 years after the universe was born, back when it was a much less peaceful place. The microwave-band static is fundamentally linked to the Big Bang, and if we map it precisely enough, we can discover a wealth of information about the age, composition and structure of the universe.

“From nano metres to light years in microseconds” That… scares the shit out of me for some reason… the sheer power of that. Wow.

[@caturdaynite7217]

I think it indicates that there is a whole lot we don't know and may never know. Why? Because, how can you see something outside of your own universe? There's is obviously more to the cosmos than just our universe. Question is, how do we explore that? Can we leave our universe and travel to another universe? Could humans or our machines survive that? Are the physical laws of another universe capable of sustaining human life or even matter as we know it? Lots of questions. Most of them are scary. What is out there?

[@Phi83400]

@@caturdaynite7217 You're right, and also let's not forget that even within our own universe we can only observe the observable part, which is shrinking (in our perspective) because of the expansion of the universe and the constancy of the speed of light. So even just inside our universe we will never be able to see the whole universe unless we find something, anything that's faster than the speed of light. If that happens, then I believe we (our descendents who will hopefully still be kind of human) will be able to see more than the observable part, and then we'll discover if there are boundaries or if it's actually infinite, or if the expansion is even true or just an effect in a region of the universe, and also if there are other universes (this one might be tricky even with FTL technology). You're completely right on the fact that we can't go to different universes, or see inside them, we could maybe notice their boundaries (if they're there at all). I think that this also relates to the fact that we can't see the microscopically small, only representations of it, and the smaller we can see, the more biased or unrealistic it looks (if you watched journey into the microcosm you know what I mean, in short: if we were scaled down to the size of a microbe, things would look very different from what we see under a microscope). My personal belief is that sizes are infinite. Both ways. I believe that if the required technology exists (which is exactly the problem) you can zoom infinitely in or out and still find things of relevance, eternally. Sorry for the long comment, i was inspired lol

[@lsudx479]

Nah. Don't be scared. We're safe now. That was in the beginning.

@@caturdaynite7217 I'm writing a sci-fi novel which includes that very capability!

[@santyclause8034]

Its kind of impossible for light to exceed teh local speed-of-light. Expansion from nanometers to Light Years in microseconds, when nothing can travel faster than light: really? Another observation: if the Universe is 13.8B years old, and its expansion (accellerating continuously since BB), is such that today we can't observe the recession of light sources past a distance of 46B light years away (Cosmic Horizon of the Observable Universe) because the light of celestial bodies travelling beyond this cosmic horizon of 46B LY in origin can never cross such a distance before it has reached a harmonic phase equilibrium that must packetize with the receding light source. But BB Inflation Epoch photon redshift to CMB, all this time later, is still observable: how is this? No light travels above the speeds the expansion of space-time accelerates at this distance: the more distant these celestial bodies are the faster their recession, even faster than light, away from us. At all this Time/Space distance their light continuously redshifts along a sliding scale down to this Cosmic Horizon vanishing point, 46B years, until it finally becomes unobservable: the whole signal packet is lost (so to speak). Whereas in microseconds during the BB inflation epoch(?) the Universe had expanded Light Years: in microseconds photons travelled multiples of the distance that light, composed of photons, travels in a year? These sound like different speeds of light, ya know? Is this the missing mass? I am reminded of Einstein's Mass Equivalence comment here, the fusion of 2 Hydrogen to one Helium results in a loss of mass that is given by energy conversion to Light. Just a thought. Finally, I recall well those initial microseconds were around 13.8B years ago - a helluva lot of microseconds have past since those few. One assumes the Universe has meanwhile continued expanding,

You left out the first CMB map, RELIKT-1 taken by the Soviet cosmologists. It took NASA for a half a century to create as accurate image.

[@Carbon_Based_Life_Form]

What? It "didn't took NASA half a century to create as accurate image" NASA created a better and MUCH more accurate image by using and collecting more data over a longer period a time and choose to release it when they were happy with the results, which is why to "took longer". Because they choose to. You're saying that as if it took NASA 50 years to "catch up" to something soviets did as if Soviets had and used super advanced satellite technology

Funny when that happens. Love your videos, astronomy is easily the most interesting science to me, and you never fail to captivate my curiosity of this fascinating universe.

[@kreggur2864]

What I like the most about this channel is how the things we don't have a firm understanding of isn't littered with baseless theories. A lot of TV shows throw in stuff like "MAYBE IT'S ALIENS???!!!" whenever something even slightly mysterious is mentioned, but here it's just just brought up as being on the limits of human understanding as well as presenting the theories of the foremost experts in the field. It just elevates the excitement about the unknown to a much higher level.

[@samuelrizzari994]

This 1000%. Every tv show goes into clickbait theories like "IS THIS CMB ACTUALLY PEOPLE FROM ANOTHER DIMENSION TRYING TO COMMUNICATE?" followed by some educated science dude saying "yeah it could definitely be communication from another dimension, but we just don't know". Then they'll show some distorted shadow figures with curious music playing, then delve into what the interdimensional shadow people would theoretically look/sound like. That shits so intriguing when your a child, but now its just like wtf come on now. Instead hearing someone say "its beyond our understanding" sparks a primal urge to learn more & solve.

[@haikalmiftah2529]

Well tbh for once the scientist was literally though like that when they detect 'strange' signal with very consistent rate. Only few years later it was found that was electromagnetic beam produced by neutron star, marking the first proved evidence of the existence of neutron star (it already covered in SEA video about neutron star.
