Summaries of Spacetime, Relativity, and Quantum Theories for beginning and advanced visitors.
In quantum mechanics, the concept of matter waves or de Broglie waves reflects…
I do not agree with the Big Bang theory on anti-matter, but the rest of this is very informative. I think I agree with Feynman's theory on anti-matter.
New kind of light created in physics breakthrough
A "super photon" created when physicists turned photons of light into a state of matter called a Bose-Einstein condensate.
What Is Gravity?
Albert Einstein proposed that matter curves space-time, and that gravity is the curve that causes objects to deviate from traveling a straight line. The distortion causes the objects that were moving along a flat plane to fall into a spherical path.
How Warp Speed Works
Einstein, Relativity and the Space-time Continuum - The space-time continuum describes how space and time are relative and how objects in motion experience time more slowly. Learn about the space-time continuum.
Ask Ethan #88: Where is the Cosmic Microwave Background?
Dark energy is real, say astronomers — Dark energy, a mysterious substance thought to be speeding up the expansion of the Universe is really there, according to a team of astronomers at the University of Portsmouth and LMU University Munich.
'Extreme Universe' puzzle deepens
The mystery surrounding the source of the highest-energy particles known in the Universe has grown deeper. The particles, known as cosmic rays, can show up with energies a million times higher than the biggest particle accelerators on Earth can produce.
