DARK MATTER'S UNKNOWN PHYSICS MAY EXPLAIN WEBB-OBSERVED MOST EARLY UNIVERSE SUPERMASSIVE BLACK HOLES 5/8: The Elephant in the Universe: Our Hundred-Year Search for Dark Matter by Govert Schilling (Author), Avi Loeb (Foreword)

In The Elephant in the Universe, Govert Schilling explores the fascinating history of the search for dark matter. Evidence for its existence comes from a wealth of astronomical observations. Theories and computer simulations of the evolution of the universe are also suggestive: they can be reconciled with astronomical measurements only if dark matter is a dominant component of nature. Physicists have devised huge, sensitive instruments to search for dark matter, which may be unlike anything else in the cosmos―some unknown elementary particle. Yet so far dark matter has escaped every experiment. Indeed, dark matter is so elusive that some scientists are beginning to suspect there might be something wrong with our theories about gravity or with the current paradigms of cosmology. Schilling interviews both believers and heretics and paints a colorful picture of the history and current status of dark matter research, with astronomers and physicists alike trying to make sense of theory and observation.

The Search for Dark Matter.

0:12.0

The elephant in the universe is the new book. The The universe doesn't hold together unless we can find something called dark matter.

0:25.0

Or unless dark matter doesn't exist, then we cannot explain how the universe holds together.

0:32.0

It's that puzzling. So Gobert has introduced

0:36.0

us to the reasoning of what this particle might look like. They call it a whim, weekly interacting massive particle, whim.

0:46.0

However, the searches continue and we're going to go to one of those searches, before we go there Gover's surprises in his

Milgram and he and his colleagues are using Newtonian physics to explain what we observe in the heavens.

1:10.0

This is the part that I loved completely because this is not contrary.

1:15.0

This is what about and what I take is there are some cosmologists who accept the contrariness of it and some who are annoyed by it?

1:28.4

Is that correct, Kober?

1:29.9

Absolutely.

1:30.9

This is an interesting story because Milgram and his colleagues, they came up with a brilliant idea because we still haven't found dark matter.

1:40.0

And we see it all around us. We see its effects in the motion of

galaxies and clusters in the rotation of galaxies in the gravitational lensing. But if you

start to realize what's actually happening,

1:52.8

the only thing we see is the gravitational effect of dark matter.

And to explain the gravitational effects that we see,

we use our current theory of gravity which is actually
