WSU: The Accelerating Universe with Adam Riess

Nobel laureate Adam Riess walks you through his team’s incredible discovery of dark energy and our accelerating universe. Explore one of the biggest mysteries in modern cosmology. #WorldSciU

This lecture was filmed on May 30, 2015 at the World Science Festival in New York City.

The Expanding Universe - 00:00:04

Cosmic Deceleration - 00:14:48

Searching for Supernovae - 00:22:36

Dark Energy - 00:43:20

So, the newly detected acceleration has overturned the Hubble Law which says the receding velocity of galaxies = Hubble constant x distance of distant galaxy. Why then still base on that law to show that expansion of the universe has quickened?

An informative talk about 'accelerating universe' and 'dark-energy'! Dark-Energy, DE, is suggested to be the cause of the 'acceleration'! It is nice to hear a Nobel laureate; Professor Adam Riess, saying "We do not know"!. There is still a lot of mysteries around. Thanks for WSU and for Professor Riess for this illuminating talk.

Thanks. How do we know the redshifted light we see of distant galaxies isn’t instead due to the effect on this light of outbound neutrinos streaming past us 🌎 from our sun ☀️ (and all other neutrino generating objects in our galaxy and all other intervening galaxies) would have on that distant galaxy’s earthbound light? (e.g. a distant bell 🔔 tower’s sound would be Doppler shifted if wind were blowing towards tower without distance expanding between tower and observer)

Assuming the growth of the loaf, would those millions of currants in the centre of stopped radiating light. since they was the birth of our beginning?
Since light carries what weight per unit atom, will there be a central Blackness drained of its mass in the centre?
