Summary

Are we alone in the universe – and if not, how many other civilisations might there be? Remarkable images and data sent back to Earth by the James Webb telescope have given a new impetus to a well-worn debate. We ask how far mathematics – and in particular a famous equation called the Drake Equation – can be used to answer one of the most fundamental questions we face. Paul Connolly investigates with the help of Catherine Heymans, Astronomer Royal for Scotland and Professor at the University of Edinburgh and Bill Diamond, President and CEO of the SETI Institute in California. Presenter: Paul Connolly Producers: Paul Connolly and Jon Bithrey Editor: Richard Vadon Production Co-ordinator: Katie Morrison Sound Engineer: David Crackles (Image: : A cluster of young stars, surrounded by clouds of interstellar gas and dust, in a nebula, located in the constellation Carina.

Hello and many thanks for downloading the more or less podcast with me Paul Connolly.

0:04.7

Each week we turn numbers in the news and elsewhere in everyday life upside down.

0:09.5

We give them a good shake and we tally up how much of what tumbles from their pockets is fact and how much is fiction.

0:17.6

Aliens do they exist or are we alone in the universe?

0:22.6

Now, this dog-gared debate has been stirred up of late

0:25.6

by remarkable images and days of being hoovered up and relayed back

0:29.4

to Earth by the James Webb Telescope,

0:32.0

first launched in 2021 and bullishing through the star speckled

0:36.2

expands as a deep space as we speak. It's served as a veritable conveyor belt of

0:41.6

interstellar discovery.

0:43.4

Indeed, in light of these and other revelations, a recent study claims we could have a hundred times

0:48.8

better a shot at finding signs of life than we previously thought.

0:53.2

But we at more or less want well more than just knowing that the odds have improved,

0:59.2

we want to know the numbers.

1:01.4

Yep, if alien life does amount to more than just a fanciable fiction,

1:05.7

then we want the mathematical means to calculate how many of those civilizations there could be,

1:11.3

and if they have either the will, or better still, a way of contacting us.

1:16.1

Now, luckily for overtime budget, somebody has already done the work for us.

1:21.1

I realize for us. I realized what we needed at this point in this meeting was to name all those things that

1:32.2

appeared to be important to the development of

1:36.7

intelligence civilizations. That is Frank Drake, astronomer extraordinary and

1:42.0

creator of the Drake equation, which were about to prod, then
