Aliens / Science close to breakthrough

Read Time:2 Minute, 37 Second

Our existence is proof that there is certainly life on other planets, since the probability that Earth is the “only” one with life in the universe is almost zero.

Aliens may use ‘quantum communication’ to send messages across interstellar space, the latest mathematical model suggests.

Aliens may also use quantum particles to communicate with us through space, say physicists who modeled how X-ray photons could travel vast interstellar distances.

They found that the photon’s message would be unlikely to encounter any obstacles.

However, humans would require a powerful quantum computer to decipher them.

A team from the University of Edinburgh ran calculations on the movement of X-rays through the void of space to see if they would encounter any obstacles.

Quantum particles, such as photons of light, are fragile and can easily fall apart if they encounter any kind of interference, such as from a gravitational field.

However, it was determined that the quantum could survive traveling at least hundreds of thousands of light-years – a greater stretch of distance than the entire Milky Way galaxy.

Extraterrestrial life can send messages through interstellar space using quantum communications, physicists from the University of Edinburgh have discovered.

Quantum communication systems are faster and more secure than regular networks because they use photons instead of computer code. The lack of obstacles in space means that it is possible to transmit messages over at least hundreds of thousands of light years.

No life beyond Earth has been found so far; and also there is no evidence that alien life has ever visited our planet.

However, this does not mean that the universe has no life other than on Earth, according to NASA.

The space agency says: “While no clear signs of life have ever been detected, the possibility of extraterrestrial biology – the scientific logic behind it – has become increasingly plausible.”

Our existence is proof that there is certainly life on other planets, since the probability that Earth is the “only” one with life in the universe is almost zero.

However, an argument against this is that – if there is extraterrestrial life, why haven’t we found any evidence for it?

Over the past few years, scientists around the world have been investigating using quantum communication here on Earth.

Quantum technology uses the effects of quantum physics – the nature of matter at the atomic and subatomic levels – for advances in communication.

Quantum communication systems are faster and more secure than regular networks because they use photons instead of computer code, which can be hacked.

It is hoped that the technology can provide an ‘unhackable’ and high-speed internet in the future. However, the biggest obstacle to the implementation of quantum systems is how sensitive they are to ‘decoherence’. This occurs when a quantum particle loses some or all of its unique characteristics as it interacts with its surroundings.

Possible obstacles include the gravitational field of large planets or stars, cosmic dust, solar winds, and the content of other particles in the interstellar medium.

In the paper, published last month in Physical Review D, the physicists describe their calculations proving that quantum particles can be transmitted over great interstellar distances.
