The Dark Matter & Dark Energy [1/5]

Filed under Physics Videos
Dark matter are invisible objects that react with matter by gravitational force. Scientists believe that the dark matter is made up of exotic particles like WIMPs(Weakly Interacting Massive Particles).In physical cosmology, dark energy is an exotic form of energy that permeates all of space and tends to increase the rate of expansion of the universe.Dark energy is the most popular way to explain recent observations that the universe appears to be expanding at an accelerating rate. In the standard model of cosmology, dark energy currently accounts for 73% of the total mass-energy of the universe.

Debunking the Kalam Cosmological Argument of William Lane Craig
October 13, 2011 by Actaphysica
Filed under Physics Videos
We hope this is the definitive take down of the Kalam Cosmological Argument. We show how it is contradictory and that the physics being used to support it doesn’t do so. We also had this video reviewed by Marcus, one of the Cosmology Advisers on Physics Forums to make sure there were no errors, his words “I think it is excellent.Your narrator comes across as really smart and personable….I don’t see any glaring errors, really amazingly good it’s charming, intelligent, visually engaging, sporadically really beautiful like the brief cut of the Hubble telescope and the volcano etc. Well-made!”

The Elegant Universe – Einstein’s Relativity
October 2, 2011 by Actaphysica
Filed under Physics Videos
Einstein’s General Theory of Relativity explained.
Video Rating: 4 / 5
This video demonstrates the effects of Einstein’s special relativity on objects that move at high velocities. More particularly, it visualizes the Lorentz transformation. The video shows a 3-dimensional view containing 2 dimensions of space and one dimension of time. This view is used to demonstrate the difference between classical physics and Einstein’s relativity, and why the latter was necessary to understand experimental results.

Becoming an astrophysicist
September 22, 2011 by Actaphysica
Filed under Physics Videos
Phil Evans from the University of Leicester talks about why he became an astrophysicist and why he loves the job. This is some “extra interview footage” from a film we made about a day in the life of astrophysicists. See the original video at www.youtube.com
In this Howard Hughes Medical Institute program, Dr. Neil deGrasse Tyson, host of the PBS program NOVA scienceNOW and director of the Hayden Planetarium at the American Museum of Natural History, sits down with Dr. Thomas Cech, president of the Howard Hughes Medical Institute, to discuss his own illuminating experiences as a graduate student, and how he became interested in science. Tyson also discusses his outreach success in making science accessible to the general public.
