What that essentially means is.

Discovery is,

advances, research, technology, unbelievable.

Without further ado, this is the naked scientist.

Hello, welcome to the naked scientist.

I'm Chris Smith, and this is the show where we bring you the latest breakthroughs and

hear from some of the biggest names in science, technology and medicine.

Speaking of which, this week we're hearing from the man who put the Milky Way and

dark matter on the map and that is Jerry Gilmore.

From Cambridge University's Institute of Continuing Education,

this is the Naked scientists. In the first half of the last century scientists realize that there must be more to space than meets the eye without some invisible force hanging onto them clusters of stars rotating around galaxies, ought to be being flung off out into space
