While it seems almost inconceivable that our civilization is alone in the cosmos, the fact still remains that we have yet to see any evidence to the contrary.

The Fermi paradox, which highlights the contradiction between the likely existence of extraterrestrial civilizations and the fact that we have still never encountered any, seems to suggest that either there are no aliens out there, or they are so rare that it is unlikely we would ever come across them.

Now, in a renewed effort to tackle at least one aspect of the Fermi paradox, scientists have proposed an audacious mission to Alpha Centauri - our nearest neighboring solar system.

It would be a mission unlike any ever undertaken before, in particular because the destination is more than 4 light years away - a distance that seems unfathomable to cover with today's technology.

The proposed spacecraft, dubbed the Fermi Explorer, would spend the first 12 years essentially building up speed within our own solar system before heading into interstellar space.The actual journey to Alpha Centauri would then take a whopping 77,000 years.

So how does this help us explain the Fermi paradox ? According to the team, the probe would demonstrate that it was possible to build a relatively inexpensive interstellar spacecraft and thus show that the universe should, in theory, be filled with such probes.

Arguably, it's a bit of a stretch, as it doesn't really prove anything in particular and certainly won't help us understand whether or not alien life is abundant in the universe.

Given how slow the spacecraft is, we are likely to overtake it in the future before it even gets to Alpha Centauri as more advanced technologies will make it possible to undertake the same trip in a shorter time.

Nonetheless, it will be interesting to see if the mission does launch in 2029 as planned.
