The Formation of our Galaxy - Professor Joseph Silk
Δημοσιεύτηκε στις 12 Φεβ 2016
Professor Joseph Silk explains what the relics of the earliest universe can tell us about our past and our future: http://www.gresham.ac.uk/lectures-and...
A
typical galaxy, like our Milky Way, has one hundred billion solar
masses in stars. It is remarkable that one can do back-of-the-envelope
estimates that lead to predictions of the characteristic mass of a
galaxy. I will describe how galaxies formed. Beginning from
infinitesimal fluctuations in the early universe, gravity helped
concentrate the matter into clouds that fragmented into stars and
assembled into galaxies. With the largest telescopes, one can look back
in time and decipher the remote signatures of galactic youth and even
birth.
The transcript and downloadable versions of the lecture are available from the Gresham College website: http://www.gresham.ac.uk/lectures-and...
Gresham
College has been giving free public lectures since 1597. This tradition
continues today with all of our five or so public lectures a week being
made available for free download from our website. There are currently
over 1,800 lectures free to access or download from the website.
