Public Lecture | Viewing the Beginning of Time from the Most Remote Places on Earth

Topic Overview:
Shortly after the birth of the universe, space was filled by a plasma that was literally red-hot. The light radiated by that plasma has traveled the vast emptiness of space for billions of years, with the expansion of the universe slowly stretching its waves until today it appears as microwave radiation. This is the Cosmic Microwave Background (CMB), a glow still visible in the night sky. This glow is almost uniform, but small variations from point to point hold information about the conditions of the universe 13.8 billion years ago. This lecture introduces the CMB, presents the sophisticated cameras we build to observe it, and describes the remote outposts of our planet where we deploy these cameras to take pictures of this faint radiation. As we image the CMB in finer and finer detail, we hope to improve our understanding of the beginning of the universe and perhaps of time itself.

About the Speaker

Zeeshan Ahmed is an observational cosmologist at the Kavli Institute for Particle Astrophysics and Cosmology and SLAC National Accelerator Laboratory. He received his PhD from Caltech in 2012 and held a postdoctoral position at Stanford University before being appointed a Panofsky Fellow at SLAC in 2015. Ahmed is a member of several scientific teams imaging the Cosmic Microwave Background (CMB) from the South Pole and the Atacama Desert in Chile. He spends his time poring over data from these cameras and devising tricks to build more powerful CMB cameras. This year, Ahmed was a recipient of the U.S. Department of Energy’s prestigious Early Career Award.

Great presentation. Just a thought, the concept of time having a beginning presents a logical paradox since one can always ask 'But what happened before that?' Time logically has no beginning.

Physics and Cosmology Students should look at this lecture in the Disproof Methodology mode of establishing degrees of credibility, and see why the QM-TIME medium-mechanism of pure-math logarithmic relative-timing ratio-rates Perspective makes practical sense in Principle of the Observable Universe, the Big Picture.

Very clear, beautifully illustrated lecture. Thank you!

I think such a concept as a quantum frame will be one of the keys to this lecture.

I
gift you a new emerging word/concept free for you to enjoy have fun adding your
definition for the word.  Jeffree of the lovevolution





Lovevolution 
Love – vo – lu – tion  {luhv = vuh – loo – tuhn}  a noun





Your
definitions: fill in the blank for this new word





Examples:
2. Unites science and spirituality philosophically into a holistic concept of
purpose.





3.
The process in time of bringing together or gravitating energy or information,
towards higher order and coherency and lower entropy creating ever more
complexity via information feedback loop towards love. *





4.
The light of light emerging developing as an expanding network of connected
information of light into higher orders of consciousness and real love.

I'm impressed with the gigantic work done by the guys, in the hardest conditions, your brilliant minds are admirable!

And the idea was also traced that the external field outside our universe has such properties that it stretches our bubble of the universe. The expansion, as it were, falls into the outside, which has a softer structure.

Addition and editing a week later.

It seems that the clarification still required. I mean the mistake that humanity is following every time with a serious step forward. Egocentrism. She is not present again in the views of the universe, I am specifically about the fact that the forces of increasing our universe lie outside our universe. That is, does the universe stretch something outside the universe.
If it is really universal, then - can the cause of the problem lie not in the plane of the problem?
