James Webb telescope watches ancient
supernova replay 3 times - And confirms something is
seriously wrong in our understanding of the universe
"The James Webb Space Telescope has zoomed in on an
ancient supernova, revealing fresh evidence that a crisis
in cosmology called the Hubble tension isn't going
anywhere soon."

Do We Need a New Theory of Gravity?
"Since Newton had his initial revelation about gravity,
our understanding of this fundamental concept has evolved
in unexpected ways. In this week’s episode, theoretical
physicist Claudia de Rham and co-host Janna Levin discuss
the ways our current understanding of gravity needs to
continue to evolve. "

Is Dark Matter Made of Primordial Black
Holes?
"Less than a trillionth of a second after the Big Bang,
rare regions in the Universe may have had a radiation
density above a critical value within their cosmic horizon
so that their self-gravity overcame cosmic expansion and
made them collapse to a primordial black hole."

Antimatter detected on International Space
Station could reveal new physics
"Eight years ago, the International Space Station detected
weird antimatter particles that challenge our entire
understanding of physics. Now, researchers have proposed
that mysterious cosmic "fireballs" could help explain the
detection."

Mice That Eat Less Live Longer - And We May
Finally Know Why
"We've known for over a century that mice and rats live
longer when they are fed less, but a new study reveals the
secret might be an imbalance between energy consumed and
burned, rather than a lack of energy or protein."

Wild New Study Suggests Gravity Can Exist
Without Mass
"What is gravity without mass? Both Newton's revolutionary
laws describing its universal effect and Einstein's
proposal of a dimpled spacetime, we've thought of gravity
as exclusively within the domain of matter."

What is the 3-body problem, and is it really
unsolvable?
"The three-body problem is a physics conundrum that has
boggled scientists since Isaac Newton's day. But what is
it, why is it so hard to solve and is the sci-fi series of
the same name really possible?"
