There have appeared many new scientific discoveries since that time, and many of them shake the foundations of the famous theory. It’s full of gaps and unanswered questions. So doesn’t this mean it’s not that perfect?
In this video, I’ll tell you: how many dimensions can the Universe have? What if the world was made of liquid? And most importantly, you’ll find out why the Big Bang theory can be wrong.
Lasers support certain structures of light known as “eigenmodes.” An international collaboration of experts in gravitational waves.
Gravitational waves are distortions or ripples in the fabric of space and time. They were first detected in 2015 by the Advanced LIGO detectors and are produced by catastrophic events such as colliding black holes, supernovae, or merging neutron stars.
Update: Meet Sagittarius A — Astronomers Reveal First Image of the Black Hole at the Heart of the Milky Way Today (May 12, 2022) at 9:00 a.m. EDT (6:00 a.m. PDT, 15:00 CEST) The European Southern Observatory (ESO) and the Event Horizon Telescope (EHT) project will hold a press conference to pres.
The above video approximates noise from the black hole at the center of the Perseus galaxy cluster, which experts discovered had a pitch over a “million billion times deeper” than the limits of human hearing, making it too deep to be heard.
A few years ago three computer scientists named Adam Bouland, Bill Fefferman, and Umesh Vazirani, wrote a paper that promises to radically change the way we think about the interiors of black holes. Inspired by their paper I will explain how black holes threaten the QECTT, and how the properties of horizons rescue the thesis, and eventually make predictions for the complexity of extracting information from behind the black hole horizon. I’ll try my best to explain enough about black holes to keep the lecture self contained.
