Light bursts out of a flying mirror

00 A dense sheet of electrons accelerated to close to the speed of light can act as a tuneable mirror that can generate bursts of laser-like radiation in the short wavelength range via reflection. A team of physicists from the Max-Planck-Institute of Quantum Optics (MPQ) in Garching, the Ludwig-Maximilians-Universit√§t (LMU) M√ºnchen, the Queens University Belfast… Read More »

Visible Spectrum: Can it be color shifted?

00 Is there any device to shift the spectrum of what is seen so red becomes orange, orange becomes yellow, yellow becomes green and so on, smoothly? A typical human eye will respond to wavelengths from about 390 to 700 nm.[1] In terms of frequency, this corresponds to a band in the vicinity of 430–790… Read More »

Scientists discover dark lightning

00 … scientists recently discovered something mind-bending about lightning: Sometimes its flashes are invisible, just sudden pulses of unexpectedly powerful radiation. It’s what Joseph Dwyer, a lightning researcher at the Florida Institute of Technology, has termed dark lightning. Unknown to Franklin but now clear to a growing roster of lightning researchers and astronomers is that… Read More »

CERN: New particle is confirmed Higgs boson

00 A new particle discovered at the Large Hadron Collider last year has been confirmed to be the Higgs boson. Here, proton-proton collisions at the Large Hadron Collider showing events consistent with the Higgs. (Credit: CERN/CMS/Taylor, L; McCauley, T) Physicists from the Atlas and CMS experiments at CERN’s Large Hadron Collider announced Thursday that they… Read More »

NASA has Found a Free Particle Accelerator Floating in Space

00 In early 2007, NASA’s Cassini spacecraft observed something extraordinary around Saturn. An unusually strong blast of solar wind sent subatomic particles crashing into the ringed planet’s magnetic field, giving rise to perhaps the most tremendous shock wave ever observed emanating from the planet. But newly announced findings reveal the biggest surprise was yet to… Read More »

Light from nothing

00 ‘Virtual particles’ can have real physical effects. A vacuum might seem like empty space, but scientists have discovered a new way to seemingly get something from that nothingness, such as light. And the finding could ultimately help scientists build incredibly powerful quantum computers or shed light on the earliest moments in the universe’s history.… Read More »

The Science Behind Owning a Universe

00 “At the level of subatomic particles the world is governed by quantum physics. Quantum theory is the most successful scientific theory ever: more successful than Newton’s laws or Einstein’s relativity! The evidence that it correctly describes reality is simply overwhelming. Yet quantum theory is very strange and goes against most of our fundamental beliefs… Read More »
