Aliens? – Maybe/Maybe Not According to One Astrobiologist

Interstellarspace01Given the vast distances in space, I’ve been wondering if it’s really feasible that other supposedly intelligent life forms (aliens) could really have ventured to Earth and be visiting us here.  Some scientists make the case that there must be lots of alien intelligence “out there” just based on numbers and statistics. Even so, they (aliens) are still faced with the same problem we are – the sheer and unmitigated vastness of our universe.

Sure, maybe wormholes exist, but what are the chances that these aliens would pop into our “neighborhood” given the incredibly huge dimensions of our universe. It would be like winning the lottery! It would be like randomly sticking a straight pin into a king-sized quilt – who can tell where the wormhole would exit? I do not think wormholes are that predictable.

University of Edinburgh Astrobiologist

CharlesCockellSo I was very interested to read an article detailing what astrobiologist Charles Cockell of the U.K. Center for Astrobiology at the University of Edinburgh thinks.

He says, “ The pervasive nature of life on Earth is leading us to make this assumption. On our planet, carbon leaches into most habitat space and provides energy for microorganisms to live. There are only a few vacant habitats that may persist for any length of time on Earth, but we cannot assume that this is the case on other planets.”

That’s a good point, because from our myopic little view on Earth, we can’t possible say for sure what lies beneath every potentially habitable planet’s crust/gases/ice. We’re making assumptions based on what we know, and I suspect, there are volumes of science that we don’t yet know because we’ve never seen environments like these other planets might present.

The Danger

Cockell continues, “It is dangerous to assume life is common across the universe. It encourages people to think that not finding signs of life is a ‘failure’ when in fact it would tell us a lot about the origins of life.”

He further points out that we may miss signs of life on other planets simply because their forms of life could be so different and varied from ours. We might not recognize it or put “two and two” together.

RoyalSocOfScienceOfficials from the Royal Society (an academy of science in the U.K.) weighed in with their opinion, “Professor Cockell explains that in coming decades, increasingly powerful telescopes and developments in spectroscopy may allow us to look for the signals of life on planets beyond our solar system. However, regardless of this, our view is still going to be heavily influenced by our knowledge of life on Earth.”

I wonder if it’s possible for us to get beyond our own understanding and assumptions so that when we look at these data we can be open to finding patterns and clues that might point to other types of life and environmental systems.

I think one thing is for sure: it’ll be a very interesting journey! What do you think?

UFO Sightings from Earth

I know there are people who have seen some very compelling alien/UFO sightings on this planet, in fact I wrote about one I think is legitimate in the Shag Harbor/Sognefjord incident. But my working theory is that these creatures aren’t very far from home, in fact, I suspect they may actually be Earthlings from the deep, dark oceans. But that’s a story for another day!

Til the next time!

One comment

  1. No offence to these scientists and their two dimensional thinking regarding the vast distances “alien” visitors have to travel. When we theorize about the fundamentals of space travel or extraterrestrial visitors, one must think outside the box. Not easy but doable.

    Centuries ago scientists were grappling about these “shooting stars” with wild theories until science caught up and discovered meteors.

    I haven’t posted for a while, been busy, but my next one will be on this subject.

    Cheers!
