Quantum vacuum: Less than zero energy

The Quantum Vacuum

Energy is a quantity that must always be positive -- at least that's what our intuition tells us. If every single particle is removed from a certain volume until there is nothing left that could possibly carry energy, then a limit has been reached. Or has it? Is it still

International team of physicists continues search for new physics

The Compact Muon Solenoid detector is a general-purpose detector at the Large Hadron Collider (LHC) in Switzerland, designed to observe any new physics phenomena that the LHC might reveal.

Dark matter, which is thought to account for nearly a quarter of matter in the universe (but has yet to be observed), has perplexed physicists for decades. They're constantly looking for something surprising to show up in experiments—results that deviate from the standard model that defines elementary physics.It's no wonder

Austrian Discovery Could Open the Door to Quantum Teleportation

The race to further understand and eventually harness the potential power of the quantum world is well underway with each year bringing scientists closer to technologies such as quantum computers and quantum encryption.More recently, a group of scientists from the University of Vienna and the Austrian Academy of Sciences, in

The Ultimate Speed Limit and Effect of Time

Speed Limit and Effect of Time

Einstein’s theory of special relativity reflects the unchanging character of the speed of light, among other things. Before Einstein space and time had appeared to be separate and absolute, but after Einstein’s work, space and time became interwoven and relative. The most famous equation of Einstein is mass-energy equation.In this
