Keith Cooper is a freelance science journalist and editor in the United Kingdom, and has a degree in physics and astrophysics from the University of Manchester. He's the author of "The Contact Paradox: Challenging Our Assumptions in the Search for Extraterrestrial Intelligence" (Bloomsbury Sigma,...
making them incredibly dense. This means that their gravitational pull is immense, for example, on the surface of a neutron star gravity is around 1 billion times stronger than its pull on Earth. This makes
Hawking is important because he made great contributions to theoretical physics and astrophysics. I highly doubt that his work has anything to do with bombs. If you think that, you have no understanding of his work. I am glad that cutting-edge medical science twice saved your life. Your stor...
Is the Universe Made of Math? The Mathematical Universe Hypothesis What Is the Steady State Theory of the Universe? Examining the Empty Nature of Matter in the Universe Different Types of Stars in the Universe
Diamagnetism: All materials displaydiamagnetism, which is the tendency to be repelled by a magnetic field. However, other types of magnetism can be stronger than diamagnetism, so it is only observed in materials that contain no unpaired electrons. When electrons pairs are present, their "spin" ...
Specifically, if we had a theory that described physics under the extreme conditions of the ultra-early Big Bang – and if that theory had been corroborated in other ways, for instance by deriving some unexplained parameters in the standard model of particle physics – then if it...
Cooling via perspiration is affected by latent and sensible heat. When there is a breeze, evaporative cooling is highly effective. Heat is dissipated away from the body due to the high latent heat of vaporization of water. However, it's much harder to cool down in a sunny location than in...
Staffed by about 140 researchers, the lab’s activities span physics, materials science, chemistry, computer science, biophysics and astrophysics. Nearly half the efforts look more than 20 years down the road-with virtually all the rest spanning 5-to-10-year horizons. The hope is that all will...
Unfortunately, there is a problem with this simple and elegant vacuum solution to the nature of dark energy. Particle physicists can make a theoretical estimate for the energy of a vacuum and they find that it is 120 orders of magnitude larger than the dark energy that the Planck results show...
