Their research focused on finding an answer to the Fermi Paradox - a long-standing contradiction between the apparent abundance of potentially habitable planets in our galaxy and the fact that mankind has yet to encounter even a single extraterrestrial life form.
The team's conclusions were based on calculating how long it would take radio signals from Earth to reach a sufficient number of solar systems to offer a reasonable chance of being picked up.
"We haven’t heard from aliens yet, as space is a big place but that doesn’t mean no one is out there," said astronomy student Evan Solomonides. "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."
