Time Travel into the Past is Nearly Impossible

Time Travel into the Past is Nearly Impossible

A number of physicists have tried to see whether travel into the past is possible or not. As predicted, they have concluded that for now, time travel into the past is almost impossible.

In 2005, an MIT graduate student hosted a convention with regard to time travel, but not many attended the same. Stephen Hawking even sent invitations for a summer soiree, but then also there were not many participants.

Triple Star System Could be Used to Resolve Problems of Fundamental Physics

According to a new report, astronomers have discovered a unique stellar system comprising two white dwarf stars and a super dense neutron star. It has been reported that all the three stars are packed within size smaller than the size of Earth's orbit around the Sun.

The best thing that helped scientists in concluding their research is the closeness of the stars because of which they have been successful in calculating accurate measurements of the system's complex gravitational interactions.

Scientists using Sound Waves to Suspend Objects in Mid-Air

It has been reported that scientists have been successful in performing various experiments with the application of ultrasonic sound waves. According to a new report, scientists are making use of sound waves to suspend materials in mid-air.

In a recent experiment, Tokyo researchers used four panels of speakers facing each other, which combines to create 'ultrasonic focal point'. These focal points are adjustable by adjusting the output from each speaker array that is placed in about 21 inches wide area.

Jupiter-Bound Juno Spacecraft Recorded Video of Earth-Moon System during High-Speed Flyby

A video of the Earth-moon system has been recorded by NASA's Jupiter-bound Juno spacecraft at the time of high-speed flyby in October. The video reveals about an extraordinary view of the two worlds that are bounded in a cosmic dance against the dark chasm of space.

These images were taken by a low-resolution camera that is mounted at the end of one of three solar array wings of the Juno spacecraft.

Scientists at South Pole Find Collection of Neutrinos

Scientists at South Pole Finds Collection of Neutrinos

A group of neutrinos from space has been found by scientists at the South Pole. These neutrinos would assist in clarifying the origins of the universe. The findings will be revealed by a group from the IceCube telescope laboratory in Antarctica in tomorrow's Science journal.

The experts think that their 28 intergalactic subatomic particles has came from exterior of the Solar System as well as from outside our galaxy, the Milky Way. These particles are implanted in one cubic kilometer of polar ice.

‘Qubits’ Held Stable for 39 Seconds at Room Temperature, New World Record

‘Qubits’ Held Stable for 39 Seconds at Room Temperature, New World Record

In order to form a new world record, researchers held an unstable quantum memory state to be stable for about 39 minutes under room temperature. The researchers have done to make it possible to store long term quantum information at room temperature.

Researchers have encoded `Qubits' of information in a silicon system for almost 100 times more than ever done before. The nature of quantum system is that they are changeable and cannot be measured and manipulated easily. But, if they are compressed and bind together they could be transformed into computing.

Commendable Self Control Confirmed by Plasma Experiment

Commendable Self Control Confirmed by Plasma Experiment

According to a latest report, the Chinese and American researchers have come up with a new way to sustain high fusion performance under balanced conditions. According to the experts this can be done by the utilization of the self generating characteristic of the plasma.

According to the scientists, much of the electrical current required for plasma regulation in a tokamak fusion reactor is generated by the plasma itself. Also for the cost effectiveness of the fusion power this self-generated current has very important implications.

NASA Celebrates Halloween with Ghostly Dying Star Images

NASA Celebrates Halloween with Ghostly Dying Star Images

According to a latest report, in order to celebrate the Halloween season, NASA has released three photographs of the disembodied or ghostly images of the ruins of dying stars.

The images are captured with the help of infrared light and they display planetary nebulae. The images clearly show the deaths of all the three stars.

One among the three stars looks like a dreadful lot resembling the Mutara Nebula from "Star Trek II: The Wrath of Khan".

Boffins use Timing Data to Examine Gravitational Waves

Boffins use Timing Data to Examine Gravitational Waves

Boffins at Australia's Commonwealth Scientific and Industrial Research Organization have revealed that they have endeavored to examine black holes by using information about Einsteinian prediction.

Post-doctoral CSIRO fellow Dr. Ryan Shannon and PhD student Vikram Ravi have figured out the likely rate of background gravitational waves in the universe. They have made it possible through analyzing data from the Parkes radio-telescope's PPTA project and a previous CSIRO-Swinburne University collaboration.

Highest Flight Completed by Grasshooper

Highest Flight Completed by Grasshooper

As per a new report, a highest flight has been completed by the Grasshooper rocket of Elon Musk. The previous week, this rocket completed its flight in order to become a viable (vertical takeoff, vertical landing) rocket.

The SpaceX had published a video on the social site displaying the 744 meter tall jump in upward direction. A test routine was called about two months back in which Grasshopper executed a creative plan. According to the plan, the rocket rose at a height of about 100 meters from its launch pad and returned back.
