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
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
Astronomers Discover Galaxies So Mind-Blowingly Huge They Break Laws Of Physics
ASTRONOMERS have discovered a set of galaxies which, in theory, are “too big and too bright” to exist. The galaxies in question are the most luminous to have ever been spotted.Such is the brightness of the galaxies that the team from the University of Massachusetts have dubbed them ‘outrageously luminous’,
7 Quantum Particles Act Like Billions in Weird Physics Experiment
Physicists have revealed that just seven quantum particles can behave as if they were in a crowd of billions.At larger scales, matter goes through changes, called phase transitions, in which (for example) water turns into a solid (ice) or a vapor (steam). Scientists were used to seeing this behavior in large
The Ultimate 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
