Scientists are now searching for a new particle (called the Unparticle) that is theorized to carry a new type of fundamental force (in addition to the four existing forces).
The existing Standard Model for Physics cannot explain things like Dark Matter, and Dark Energy, which are thought to comprise about 96% of the universe. Physics has a long way to go before it can even begin to explain how most of the universe functions.
The foundations of Quantum Mechanics are being shaken by researchers led by Aephraim Steinberg at The University of Toronto, whose studies cast doubt on the Heisenberg Uncertainty Principle. Earlier, the same researchers had shown that a photon could exist as both a particle and a wave at the same time, something not permitted by Quantum Mechanics.
Supersymmetry predicts the existence of enigmatic "super particles". Researchers at the Large Hadron Collider have detected one of the rarest particle decays seen in Nature. The finding deals a significant blow to the theory of physics known as supersymmetry.
Scientists have succeeded (1997) in converting light (photons) into matter anti-matter pairs. But what is matter?
The highest-resolution camera ever built has begun its quest to pin down the mysterious stuff that makes up nearly three-quarters of our Universe.
Does Time slow down for top sports stars? Yes, say some neuroscientists.
What is the smallest possible object in the universe?
This question was asked by the Greeks a long time ago, and their answer was: The Atom We've come a long way since then, but there are perhaps more unanswered questions.
Researchers have spotted visible-light evidence for one of astronomy's most elusive targets - gravity waves - in the orbit of a pair of dead stars.
Until now, these ripples in space-time, first predicted by Einstein, have only been inferred from radio-wave sources.
But a change in the orbits of two white dwarf stars orbiting one another 3,000 light-years away is further proof of the waves that can literally be seen.
New theory says that the beginning of the universe was really the result of a Big Chill from the freezing of existing matter.
