I am willing to ask a question that will probably make me look ignorant.
Do electrons exist as particles? Could they whiz about the early universe as described? Aren't they just one aspect of standing waves in fields to which protons are another aspect? -
Professor Copeland is easy to listen to without getting bored or sleepy!

Got scarejumped by Prof. Copeland and his smashing photon (3:29)

This, yes, THIS!
1. Does the CMB have a rest frame, and are we moving relative to it? (Possible dipole explanation, but it breaks everything else...)
2. COBE -> WMAP -> Planck -> ??? What's next in exploring the whole-sky CMB?
3. What have we learned (since BICEP2) about E-mode and B-mode CMB polarization? Will this finally end all talk about cosmic strings?
4. Does CDM have any imprint on the CMB? If so, what is it and where is it? If not, why not, and what does it tell us about possible CDM candidates?
So many fundamental questions! -
I liked his Explanation but can somebody explain the apparent anomalies in the CMB map ie the extreme cold spot? cus apparently it doesnt go with the Standard Model?
-
Simple and easy to understand without turning us into fools and giving "dummy" examples. Excellent video! Thanks!
-
He says that if you got radiation in a box that's expanding, it cools down, its wavelength stretches. Therefore it loses energy right? How does the law of conservation of energy hold then? Can the lost energy be also the cause of accelerated expanding of space?
-
Are the temperature fluctuations of the background microwave radiation completely uncorrelated with observable astronomical entities or structures, or are they related somehow?
-
Warning Will Robinson, I detect a Geocentrist on this board. Mark Wyatt.

off all the lectures, videos etc that I have seen on this particular subject this explanation for me at least, is the best one. The way the professor explains it just clicks like a light bulb just lit up lol Thank you for this video I truly do enjoy Dr Copeland and his way of explaining things. It would be just a privilege to take any class from him in my honest opinion.

So fluctuation created the laws of the universe. Gravity, quantum mechanics thermodynamics.
Question:
How did galaxies and clusters of galaxies develop since atoms are moving away from each other? And how do you account the Energy before inflation to account the Universe (ZERO, matter vs antimatter )? So if there was nothing in the first place, then HOW AND WHY it even happen in the first place?
This theory is a direct violation of intelligence.
This theory is a direct violation of the Second Law of Thermodynamics
This theory is a direct violation of reason. -
All of this is pseudoscience at its best. They have taken a picture with so much noice that no one could be able to find the CMB in it. The forground noice is a factor of 1000 compare to the suposed CMB. To solve this they fiddled with the data to take away what wasn't supose to be there, to finaly find the wavelengths they expect to be from the cosmic microwave background (based on previous flawed experiments). Not only that, but the fiddeling with the data from all of the images taken with Planck could vary with over 40% from different years, because non of the images are reproduceable.
There should at least be one things when it comes to the microwave background and that is reproducibility, especialy when we are talking about near the begining of the universe.
All of this can be explained with an analogy: We have a huge pile of aproximatly 1000 rocks and somewhere there might be a specific rock with specific properties, but we do not know if it exist or what these properties realy are.
When things like this are made in other field, people would call you a complete moron. But in cosmology it is an achievement. In the other hand, when you send up a super expensive experiment in to space, I guess it isn't that easy to later admit that it was complete BS all along.
What so ever, that is not a image, just alot of indistinguishable noice. -
Very well explained
-
Please someone answer this question if you can. If this light was released a few hundred thousand years after the big bang, how did we (our matter) get to where we are now, before this light reached us? The universe doesn't expand faster than light does it? If it did the light would never reach us. Wouldn't we have to out run it for some of the 13 billion years then slow down for it top catch us up? Which I know doesn't make sense.

Great to watch this after the latest discoveries and, of course, Brady's videos. A storyline of possible discovery!
-
no

this guy is a genius
-
"Recent observations suggest that the density of hydrogen nuclei could at least one per square meter on average!
Therefore the CMB radiation must be mainly from cold hydrogen in space spherically distributed around us." -
Hey, sorry if it is an absurd, but...
Couldn´t the Cosmic Radiation the the dark energy?
Just came in my minda suddenly... -
11:48 I don't feel as though he answered the "determinism" question very well, or at least I didn't understand what he was trying to say. He just said, the formation of the structures were random, which were a result of the early conditions, so he didn't really say anything. Can someone explain this to me?
