MessageToEagle.com – We know they are out there, but what do they look like?
That question has intrigued many scientists over the years and there are those who believe that extraterrestrials will not be humanoids at all!
Among them is Dr Alderin-Pocock, a leading a satellite expert and government adviser, at European space company Astrium who thinks that life is likely to have evolved very differently on other planets.
Based on recent astronomical discoveries, Dr Alderin-Pocock speculates that as many as four intelligent extraterrestrial civilisations could exist in our galaxy, the Milky Way. But they are so far away it is unlikely we will ever meet them.
“The Voyager 1 spacecraft, which is carrying a recording of greetings from Earth in different languages, has been travelling through the Solar System since the 1970s and has only just made it into deep space,” she said.
“To get to our nearest neighbouring star, Proxima Centauri, would take it 76,000 years.”
“If our intelligent aliens existed only during the time of the dinosaurs on Earth, it’s not much good to us.
This leaves us with an estimate of four intelligent alien civilisations in our galaxy with a means to communicate and overlapping in time with humans,” she said.
But what makes Dr Alderin-Pocock think aliens will look like enormous jelly-fish?
“Our imaginations are naturally constrained by what we see around us, and the conventional wisdom has been that life needs water and is carbon-based.
But some researchers are doing exciting work, playing with ideas such as silicon-based life forms.
Silicon is just below carbon in the periodic table, has some chemical similarities, and is widely available in the universe.
So perhaps we could imagine similar instructions to DNA but with silicon.
Maybe life doesn’t have to resemble anything like DNA at all,” said Dr Alderin-Pocock, who described her ET as part of Science Month on TV channel Eden.
Such extraterrestrial life-forms described by Dr Alderin-Pocock would have no chance of surviving, finding the damp oxygenated atmosphere lethally corrosive.
The alien jellyfish Dr. Alderin-Pocock discusses would not live not in the sea, but in the atmosphere of a Jupiter-like planet, where they float around and they would communicate via pulses of light.
