A team of astronomers has predicted that extraterrestrial aliens will make contact with the human race, but it might not be for another 1,500 years, .
This calculation was based on the likelihood of technological civilisations arising among the stars, and the approximate length of time they had been transmitting signals across space.
The scientists concluded that there was no reason to think we are alone in the universe. All we need is just to exercise a little patience.
“We haven’t heard from aliens yet, as space is a big place – but that doesn’t mean no one is out there,” said US researcher Evan Solomonides, a PhD student from Cornell University.
“It’s possible to hear any time at all, but it becomes likely we will have heard around 1,500 years from now.
“Until then, it is possible that we appear to be alone – even if we are not. But if we stop listening or looking, we may miss the signals. So we should keep looking.”
There are more than 200 billion stars in the Milky Way, almost half of which may host Earth=like planets, according to one estimate.
If life is not unique to the Earth, and has evolved in a similar way elsewhere, the galaxy should be teeming with civilisations. Yet not one confirmed alien signal has ever been detected.
