Physicists have managed to find the origin for the neutrinos that pass through the Earth with at high energy, and have at the same time…
You exist. You shouldn’t. Stars and galaxies and planets exist. They shouldn’t. The nascent universe contained equal parts of matter and antimatter that should…
Conservation laws are among the most important tools in physics. They feel as fundamental as you can get. And yet they’re wrong - or…
It’s the most famous prediction of perhaps the most famous genius of our time ... Stephen Hawking's theory of Hawking Radiation.
String theory merges two revolutionary theories of modern physics -- quantum mechanics and general relativity -- into a common framework. Quantum mechanics is very…
Brian Greene moderates this fascinating program exploring the fundamental principles of Quantum Physics. Anyone with an interest in science will enjoy this thought-provoking and highly…
In honor of Dark Matter Day, join Origins Project director Lawrence Krauss for an evening of intrigue and science. He discusses the issue of dark…
Theories of the multiverse suggest that life-containing universes are incredibly rare. We live in one of these, whether by cosmological natural selection or by the…
The quantum field theory predicts that there exists an energy of the vacuum resulting from the non-zero zero-point energies of the quantum fields that fill…
Einstein's theory of relativity revolutionized our view of the universe, positing a space-time continuum undergirding all reality. Equally impactful has been quantum mechanics, which describe…
PBS Space-Time talks about vacuum energy from a theoretical standpoint. From the perspective of quantum field theory, every point in space is represented by a…
We’ve known for some time that around 95% of the energy content of the universe is in dark matter and dark energy. This dark sector…
A group at the JILA research institute in Boulder, Colorado, has demonstrated what it describes as a "radically different" approach that probes electrons inside larger…
Neil deGrasse Tyson presents his new book "Astrophysics for People in a Hurry" at 92Y event. In the conversation, he talks about the universe, dark…
PBS Space Time asks: How do we study nothing? It turns out that "nothing" is one of the most interesting somethings in all of physics.…
Can we ever achieve absolute cold? PBS Space-Time investigates. Many experimental physicists have spent their careers trying to cool things to absolute zero. This state…
Kip Stephen Thorne is an American theoretical physicist, known for his contributions in gravitational physics and astrophysics. A longtime friend and colleague of Stephen Hawking…
Rainer Weiss ’55, PhD ’62, professor emeritus of physics at MIT, has won the Nobel Prize in physics for 2017. Weiss won half of the…
The Nobel Prize in Physics 2017 is awarded one-half to Rainer Weiss, the other half jointly to Barry C. Barish and Kip S. Thorne "for…
The laws of physics are the same everywhere in the universe and will be, for all time, right? Recent findings suggest that these constants might…
