Chris Impey is a Distinguished Professor of Astronomy at the University of Arizona and has penned eight popular science books, and he has even taught cosmology to Tibetan monks. He told The Weekend there is a spiritual aspect to the belief in the existence of aliens.
Modern media - including hit movies such as ET and Close Encounters of the Third Kind - drew on Biblical stories and director Stephen Spielberg was a clever film-maker who tapped into a need, Professor Impey said. So I agree with that. I think he was onto something when he did that and that's why those movies resonate. He said he is amused by claims aliens are already on Earth but are concealing themselves and describes such claims as part of the conspiracy theories that are prevalent these days.
He agreed that per capita reporting of UFOs in the United States is very high in comparison with other countries. Helen Sharman, who visited the Soviet Mir space station in , told the Observer newspaper on Sunday that "aliens exist, there's no two ways about it.
Maybe not. Then, in a tantalizing theory that should probably make you very suspicious of your colleagues, Sharman added: "It's possible they're here right now and we simply can't see them. Sharman was the first of seven Britons to enter space. Sharman became the first Briton in space in Read More. The chemist spent eight days as a researcher on the space mission when she was 27, making her one of the youngest people to enter orbit. A few years ago, scientists at Caltech managed to breed a bacterial protein that created bonds with silicon — essentially bringing silicon to life.
So even though silicon is inflexible compared with carbon, it could perhaps find ways to assemble into living organisms, potentially including carbon. To find it, we have to somehow think outside of the terrestrial biology box and figure out ways of recognising lifeforms that are fundamentally different from the carbon-based form. There are plenty of experiments testing out these alternative biochemistries, such as the one from Caltech. Regardless of the belief held by many that life exists elsewhere in the universe, we have no evidence for that.
So it is important to consider all life as precious, no matter its size, quantity or location. The Earth supports the only known life in the universe. So no matter what form life elsewhere in the solar system or universe may take, we have to make sure we protect it from harmful contamination — whether it is terrestrial life or alien lifeforms.
