Scientists calculate number of intelligent alien species

Intelligent civilisations are out there and there could be thousands of them, according to an Edinburgh scientist.

The discovery of more than 330 planets outside our solar system in recent years has helped refine the number of life forms that are likely to exist.

The current research estimates that there are at least 361 intelligent civilisations in our Galaxy and possibly as many as 38,000.
What? 8O

I'd like to know how they came up with that number.

They took the population of Hollywood and divided it by the average celebrity IQ. :wink:

Obviously out there somewhere, as there is not much intelligent life around where I live. In fact I suspect an alien spaceship may have crashed on the local estate. The occupants wear hoodies and communicate with grunts

They started by saying the possibility was somewhere between 'over a million' and 'less than one'..... then guessed. Far to many variables to come up with a number so this report should be taken with a 'pinch of salt'.... about enough salt to clear the snow bound roads of Britain.

I met quite a few alien species; mostly they were above the rank of Major - but very few could really be described as 'intelligent'.

I'll get my belt and beret off..........

It's research to try and refine some of the values in the Drake equation:

Pointless exercise IMO, a cursory glance reveals that the number 42 is not included, ergo; waste of time.
