Podcast: Measuring gravity on tiny scales

The smallest measurement of gravity ever recorded

 

 

Physicists examine the gravitational pull between two tiny masses, and how fossil lampreys could shake-up the field of vertebrate evolution.

In this episode:

00:47 Gravity, on the small scale

This week, researchers have captured the smallest measurement of gravity on record, by measuring the pull between two tiny gold spheres. This experiment opens the door for future experiments to investigate the fundamental forces of nature and the quantum nature of gravity.

Research Article: Westphal et al.

News and Views: Ultra-weak gravitational field detected

07:37 Research Highlights

Research shows that people often don’t know when a conversation should end, and the cuttlefish that show remarkable self control.

Research Highlight: How long should a conversation last? The people involved haven’t a clue

10:18 Lamprey evolution

The larval stage of lamprey growth has long been thought to resemble the kind of early animal that all vertebrates evolved from. However, new research looking at the fossils of lamprey species suggests that this popular hypothesis may be incorrect.

Otto Knotzer yes he is interesting Thanks
