It never happened, the universe was never created. It is being created now, it's always now, and if the archetypes stopped doing what they do, everything would cease as tho it never were in an instant. Logic relies on time, both are illusion. Age of the universe is the wrong question. Power greed will never see reality.

If you want to know more about the history of cosmology, I can highly recommend two books by Timothy Ferris: "Coming of Age in the Milky Way" and "The Whole Shebang". They combine to make a very readable account from Copernicus to the modern day. The latter book is over 20 years old at this point so doesn't include the progress made in the 21st century.

Commentary on Ryle versus Hoyle by Barbara Gamow, George Gamow's wife: "Your years of toil," Said Ryle to Hoyle, "Are wasted years, believe me. The steady state Is out of date. Unless my eyes deceive me, My telescope Has dashed your hope; Your tenets are refuted. Let me be terse: Our universe Grows daily more diluted!" Said Hoyle, "You quote Lemaître, I note, And Gamow. Well, forget them! That errant gang And their Big Bang- Why aid them and abet them? You see, my friend, It has no end And there was no beginning, As Bondi, Gold, And I will hold Until our hair is thinning!" "Not so!" cried Ryle With rising bile And straining at the tether; "Far galaxies Are, as one sees, More tightly packed together!" "You make me boil!" Exploded Hoyle, His statement rearranging; "New matter's born Each night and morn. The picture is unchanging!" "Come off it, Hoyle! I aim to foil You yet" (The fun commences) "And in a while" Continued Ryle, "I'll bring you to your senses!"

I stopped following the argumentations on redshift after i heard an interview with Subir Sarkar, Oxford particle phycisist, with Sabine Hossenfelder in which he explains that results aquired with the minimal amount of data used in Cosmology would be thrown out immediatly in Particle physics. It is like trying to get 100% explanation with 1% of data. In Particle Physics they do not have that problem, because they can just create more data. Cosmology is entirely dependent on observation. Which, to date, is extremely limited. "scientific tests", "evidence"...sorry, in Cosmology it is all fairy tales.

I am old enough to remember when the Steady State Theory was the leading theory. The name Big Bang became popular after a best seller book (Brief History of Time) popularised it, but in the 60’s I mostly heard it referred to as Cosmic Egg cosmology, or a finite, or oscillatory universe. The Big Bang name existed, but it wasn’t nearly as much talked about with the strong name recognition that accompanies it now. I do remember the conversation, for the public, was dominated by Hoyle, so naturally he emphasised the significance of his own theory. At the time the age of the universe was commonly quoted as 10 to 20 billion years, or maybe eternal. It has been fascinating to see the Big Bang grow rapidly in the 70’s and 80’s. I remember Alan Guth and Inflation and by that time Hoyles ideas were rapidly receding and Big Bang had become the default, and everyone knew the subtitle to Hawking’s book - From Big Bang to Black Holes. My memories suggest to me that while Hoyle coined the name Big Bang, it was Hawking more than anyone that really put it into the vocabulary of the man in the street.

All my life I've struggled understanding cosmic microwave background, because all descriptions I've read about it just gloss over it the same way you do in this video without actually explaining it. And yet it is so simple to explain and understand. The very early universe was not transparent, yet it had abundant sources of electromagnetic radiation. It was like the universe was filled with brightly lit fog that you could not see through. As it expanded it became transparent at one point in time T (I think it was when electrons settled around hydrogen atoms). When we look into distant universe we look into the past. How far can we look? The limit is the point T. Anywhere we look, we ultimately can see this 'barrier' of fog (only massively redshifted). That's it.

Hey, thanks! This was a very concise, yet well-explained trip through cosmology during the last several centuries! A couple things I noted, if you please: Around 13 min: Spelling - Pope Pius XII (there's no "o" in the name) 25m 10s: You're explaining the wonders of "Brilliant," showing one of their screens on cosmology. I believe they might have a slight error there - they say that the WMAP (Wilkinson Microwave Anisotropy Probe) all-sky map is in the Mollweide projection, which they compare with its use for world maps. The world map they show has all the latitude circles mapped into straight lines; I don't think that's the right projection for the sky map, then. Let me explain. The instrument that produced the differential CMBR intensity map that you show for CoBE, was the DMR (Differential Microwave Radiometer). I worked as a scientific data analysis software engineer on the CoBE project, 1985-95. Part of what I did, was to deal with sky maps much like this one, that we made for all 3 instruments. The projection we used can be mathematically described in 3 steps; think of a world map as an example. 1. You start with the complete globe, make a "cut" along the 180º meridian, and collapse it around, along latitude circles, dividing all longitudes by 2, leaving latitude values alone, so that you now have a hemisphere, from longitudes -90º to +90º. 2. Now apply a polar equal-area projection to make a planar map, which will be a circle; the "pole" of the projection being (0º,0º) lon-lat. The equator maps into its horizontal diameter. 3. Superimpose an x-y coordinate system on that circle, origin at (0º,0º); so that the x-axis is on the equator. Now stretch that circle into a 2-by-1 ellipse by doubling all the x-coordinates. The result is the projection we used, whose name I've forgotten; but the only latitude circle that maps to a straight line, is the equator. The others all curve, with increasing curvature toward each pole, in the direction of "wrapping" around their respective poles. (This curvature happened in step 2, and was preserved in step 3.) By construction, it is an equal-area projection (each step preserves area ratios). Now, that was on CoBE. I was not connected to the WMAP project, but I believe its PI (Principal Investigator), was Chuck Bennett, who was the Deputy PI on CoBE/DMR (PI, George Smoot). Given that WMAP was the successor to DMR (a higher-res DMR!), I think it very likely that the same projection would have been used there. We (CoBE) didn't invent that projection; it had been used a lot before CoBE, so it was part of the mathematical "toolbox" of NASA (and outside of NASA, too, I believe) sky-mapping projects. ADDENDUM: Thanks to a reply to this comment by Peer Henselmans, I now know that the projection we used was (what we thought was called) an Aitoff projection. I see that this was the wrong name for what we were actually using, though; Aitoff is not equal-area. The correct name is the Hammer projection, which *is* equal-area. Fred
@ffggddss4 жыл бұрын
@@peerhenselmans Doesn't ring a bell, but I'll look into it. Thanks, in either case! Hey, just looked it up. Not even close to being equal-area - BUT - it pointed me to a name I DID recognize: Aitoff projection (1889). That was what we *called* the projection I was trying to think of, and that we used. But come to find out, from the description of the way it's produced, it isn't equal-area either! It looks very close to what we actually used, which WAS equal-area, and whose correct name is the "Hammer projection" (1892). The math for it, given on the Wikipedia page, is exactly what we were using for the CoBE skymaps. [BTW, the equal-area property was important to us, and to researchers who would use our data products, because it gives equal visual "weight" to all regions of the sky.] So we were using the wrong name all along! Thanks again, even more, for leading me right to where I could clear this whole thing up!! Fred

The Big Bang theory isn't a theory about how the universe actually originated; it's about how the universe evolved since the instant (10⁻⁴³s) after it was a singularity. The origin of that singularity is a question for other theories to answer, and some like eternal inflation have possibly already made progress on that front. The discrepancy can be likened to the difference between biological evolution and abiogenesis: whereas evolution explains how all life has developed out of its earliest ancestral replicator, it doesn't precisely describe the nature of that first replicator or how it came into being, and that matter is the subject of other competing theories (like the RNA world hypothesis).

We could therefore get almost anywhere in the universe within a human lifetime. Note: this does not take account of the expansion of space-time itself, which kind of messes with the whole idea. But that doesn't really matter too much, because there's no going back. Also, when traveling that fast, you wouldn't have a chance to stop and look around at where you are. Or even really see anything much...

I absolutely LOVE how you explain simply, these hugely complex concepts. My question: Redshift explains the expanding universe, the further away an object is from us the greater the redshift, also the further away an object is the more into the past you are looking. Is it possible that frequency reduction (redshift) is merely the result of entropy? That these photons are merely losing energy over these huge periods of time? Are objects that we know are moving toward us (Like andromeda) blueshifted? Does Doppler effect come into play?

I hope that question makes sense.
@isaackitone4 жыл бұрын
I thought all of us (everything) are radio-wave emitting bodies. E.g. light (a radio-wave) hits your body, and reflects to someone's eye for that eye to see you. Same as planets, etc, and for stars, they actually do emit visible light, UV, infrared, lower frequency radio, X-rays, gamma rays, and this embarks on its journey in form of photons at 300,000m/s to our eyes/telescopes/antennas.

Sorry for the nerd overload... - A big bang makes sense, because of the overwhelming evidence for it. But how did it come to occur? - A universe from nothing as suggested by Laurence Krauss, seems to our human senses and experience, to be unpalatable and therefor we say unlikely. - The conformal cyclic cosmology (CCC) hypothesis seems perfectly reasonable on the surface... it allows for lots of what we have seen and predicted; rapid expansion, a big crunch and a repeating big bang. But it does nothing to answer where did the first big bang come from? and in that system could there be a last one? I love learning about all of these things, but it feels like every time i lift up a pebble in terms of understanding, i see another rock... At least I think i’ve worked out the meaning of life. I believe that meaning is given by the inventor or creator of whatever it may be. So since we don’t have a creator, I don’t think we have a predetermined purpose, we’re just here. For that reason, the meaning of your life is what you want it to be. Pursue things that make you happy, and it will not be a wasted life.

I suspect that the issue keeping us from answering how we get "something from nothing" relies on answering how "dark" is converted to "baryonic". Everything you've described in this excellent history lesson addresses observations of and theories regarding the observable universe (e.g., the baryonic universe). But because we can't "observe" anything else, we're forced to assume there is nothing other than the observable universe. There may, in fact, be a steady state foundation from which the baryonic universe emerges - a foundation we generally refer to as the dark universe consisting of dark energy and dark matter. And so I also suspect that clever cosmologists will, someday (probably not in my lifetime) discover enough about the dark universe that this question will be answered - the question(s) regarding the existence of a steady state universe that is unobservable (but implied) that yields a baryonic component that behaves in the ways we're able to observe and predict (with resonable certainty). Rather than relying on mythology, I personally believe that the relationship between the baryonic and dark components of "the universe [redefining the "universe" to include both], once understood, answers nearly all questions. The only question that can never be answered is whether there really ever was a beginning to the [redefined] universe.

You learned in grad school that the heavier elements were produced by neutron bombardment of lighter elements: Rapid and Slow Rapid meaning that the next neutron hits before the resulting nucleus can decay, Slow meaning that the nucleus had had time to decay before the next neutron hits. However, there are other mechanisms that are not widely publicized. 1. Neutronium fragmentation: When sufficiently violent rebound explosion occurred, neutronium produced by stellar collapse was subjected to pressures sufficiently low for it to shatter into unstable super-massive nuclei which decayed into the elements heavier than iron. 2. Reverse fission: In a super-dense neutron-rich environment at extreme temperatures, post iron nuclei are forced to fuse into much heavier but highly unstable nuclei, which in turn absorb the ambient neutrons and are converted into stable and meta-stable nuclei that are today's heavy elements. Mechanisms 1 and 2 are not necessarily distinct, but overlap.
