Physicists Say the Universe Wasn’t Born from the Big Bang. But How?

Posted by in categories: cosmology, physics

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.

Gravitational Wave Scientists Pioneer New Laser Mode Sensor With Unprecedented Precision

Posted by in categories: cosmology, physics

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.

Measuring a Black Hole Shadow

Posted by in categories: cosmology, robotics/AI

A new technique for measuring the shadows cast by a black hole binary could enable astronomers to glean details about these massive systems.


During its first keynote at Google I/O 2022, Google detailed its latest language model, LaMDA 2, and an app called AI Test Kitchen.

NASA released new audio approximating the sound of two black holes on May 4th

Posted by in category: cosmology

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.

Quantum Colloquium.

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.
