Physicists Hope to Catch Neutrons in the Act of Jumping from Our Universe to Another. The notion of multiple universes is one that cosmologists like to theorize about but generally don’t relish proving, mainly because doing so would be very difficult.
But a team of researchers that showed a few years ago how matter might travel between our universe and others now think they ought to be able to observe this phenomenon in action using existing technology, lending credence to the multiverse theory. All they need is a neutron bottle, some neutrons, and a year.

Two high-profile entrepreneurs say they want to put a DNA sequencing machine on the surface of Mars in a bid to prove the existence of extraterrestrial life.
In what could become a race for the first extraterrestrial genome, researcher J. Craig Venter said Tuesday that his Maryland academic institute and his company, Synthetic Genomics, would develop a machine capable of sequencing and beaming back DNA data from the planet. Separately, Jonathan Rothberg, founder of Ion Torrent, a DNA sequencing company, is collaborating on an effort to equip his company's "Personal Genome Machine" for a similar task.
Although neither team yet has a berth on Mars rocket, their plans reflect the belief that the simplest way to prove there is life on Mars is to send a DNA sequencing machine. "The reason to take a device all the way to Mars and not bring back the sample is because of contamination. Via Dr. 8 Shocking Things We Learned From Stephen Hawking's Book. J.

Introducing the 'antimagnet' Researchers in Spain have proposed a new type of invisibility cloak that could hide objects from magnetic fields.
The cloak – which has not been built yet – is designed to have a dual effect. It ensures that a magnetic field generated inside the cloak does not leak outside, and it ensures that the cloak and its contents cannot be detected by an external magnetic field. If it can be realized as a practical device, the technology could prove useful in industrial applications that require specific magnetic environments. The first invisibility cloak was unveiled in 2006 and worked for electromagnetic radiation in the microwave range. It and subsequent cloaks have been based on metamaterials – materials that have been artificially engineered to have specific electromagnetic properties. How to turn darkness into light. Quantum mechanics tells us that the vacuum is not empty but is filled with virtual particles that pop into and out of existence.
Normally these particles are hidden from our view, but now a team of physicists has used the electrical equivalent of an ultrafast mirror to convert virtual photons into real electromagnetic radiation. Known as the dynamical Casimir effect, it was first predicted more than 40 years ago. The static Casimir effect, put forward by Dutch physicist Hendrik Casimir in 1948, involves two perfectly reflecting parallel mirrors that, when placed in a vacuum, will be attracted to one another. This attractive force is caused by the radiation pressure exerted by virtual photons outside the mirrors and the fact that this pressure exceeds the pressure between the mirrors because of the limited number of modes of electromagnetic vibration that are permitted within this gap.
