A large number of specific types of particles (known as scalars) were created during cosmic inflation. If dark matter has any connection with these scalar particles, it may predate the Big Bang. About 85 percent of the mass of the universe is made...
Although space mining sounds pretty sci-fi, it will be a reality in the future. Researchers are investigating the performance of the particular bacterium to extract metals from asteroids. The bacterium named Shewanella oneidensis has been known to...
Astrophysicists study 41 nearby galaxy clusters to reveal connections between hot gas, dark matter, and stars. The sum of stars and gas across the clusters is a fixed fraction of the dark matter mass. According to the Standard Model of particle...
The largest type of black holes — called supermassive black holes — have masses of the order of hundreds of thousands to billions of times the mass of the Sun. The mass of our Sun is 1.989 x 1030 kilograms, approximately 333,000 times...
Since the establishment of space travel, only three countries have been able to launch humans into space. The first person to travel into space was a Russian cosmonaut Yuri Gagarin in 1961, who orbited the earth in the Vostok 1 on April 12, 1961...
Researchers measure the current system responsible for Jupiter’s powerful auroras, using data obtained from Juno. They found Jupiter’s auroras are mostly powered by alternating currents, instead of direct currents. Jupiter’s...
Planet X is a hypothetical planet that is located about 400 astronomical units (AU) away. It may take up to 20,000 Earth years to complete one full orbit around our Sun. The planet has not yet been observed but mathematical calculations suggest it...
The possibility of the existence of white holes was first suggested by a theoretical astrophysicist Igor Novikov in 1964. A white hole is a hypothetical region in spacetime, which is predicted as part of a solution to the Einstein field equations...
There are ways to make gravity work in 2(space)+1(time) dimensional universe. A physicist showed how a scalar gravitational field would work in two spatial dimensions, enabling stable orbits and a logical cosmology. Have you ever wondered how life...
Black holes are one of the most fascinating objects found in the Universe. They are celestial bodies of extremely intense gravity from which nothing can escape – not a planet, not a moon, and not even light. Anything that crosses the event...
