What do Scientists think about Aliens?

You might be surprised, but a lot of scientists have serious thoughts and theories about extraterrestrials - How they travel; how they might looks like and what their intentions are.


are aliens real?

Are UFOs real? Do Aliens exist?


It turns out that there are a lot of serious scientists who think about that matter. Here are some of the most prominent theories on UFOs & Aliens by reputable scientists.


Aliens will send machines first! ๐Ÿ›ธ


Space travel is a long journey and an enormous investment. So if aliens want to make contact with Earth, they have to send a robot or computer. In popular culture, aliens get out of spacecraft to get to Earth. However, scientists such as astronomer Seth Shostak of the SETI Institute dispute this idea.


It's not something that opens up and we're going to see strange aliens coming, "Shostak said in an interview. Instead, he and other scientists suggest that alien visitors could be machines. Steven J. Dick, an astronomer and chief historian at NASA, has argued in an essay that "extraterrestrial intelligence" is postbiological rather than artificial. There are limits to the biology of flesh and blood and the brain, he wrote, and cultural evolution is the result of methods to improve intelligence beyond these limits. It's likely that there are robotic arms out there somewhere.


In fact, what makes alien visits more likely is that "silicon-based creatures are likely to be active in space and have long-lived systems that are essentially immortal," Shostak wrote in the release. They are the kind of creatures we will encounter before we encounter anything else.


Aliens look like us humans. ๐Ÿ‘ฝ


Simon Conway Morris, an evolutionary biologist at Cambridge, believes there is a good chance that intelligent alien life looks very similar to us. Things we think are important, he said in an interview, such as cognitive sophistication, big brains, intelligence and tool-making, are highly convergent. Different species evolved in similar patterns, he argues, and the runes of evolution would be the same on other planets.

If there are other planets that look very similar to planet Earth, as the Kepler spacecraft has discovered, the probability of human-like alien intelligence on these planets is not very great. The results of evolution are at least reasonably predictable, Morris said, and if that's true of Earth, it's also true of the Milky Way. Stephen Hawking has made his views on alien life clear.


They might be hostile towards us... ๐Ÿ’ฅ


If aliens visited us, "the result would look like Christopher Columbus landed in America and didn't turn out to be Indian," Hawking said in an interview. 'Any civilisation that reads one of our messages will be billions of years ahead of us. They will be much more powerful and will not see us as valuable as bacteria.

Other scientists have found that aliens, like humans, value natural resources. But some suspect that resources in the universe are finite, they say.


Aliens might be contaminated! ๐Ÿ‘พ


You thought the Covid-Pandemic was bad? ...Cross-planet contamination is another dangerous possibility that astrobiologists are only beginning to consider. That is why so many safety protocols have been put in place to protect the Earth from unknown microbes in interstellar samples.

Earth's environmental ecology and biosphere is so complex that we don't want to release native Martian microbes into the Earth or Mars-like regions of the planet. There are similarities between the warm, dry human body and the cold, dry Martian environment and the environments on Earth and Mars where life could flourish if carried out by a probe or human mission, writes David Warmflash, an astrobiologist.


We are in for a surprise! ๐ŸŽ


No one can be sure what extraterrestrial life would look like, in what form it would be, what its motives for contact with humans would be, or even know how it would behave.


Evolution is based on the survival of the strongest and we have good reason to believe that aggressive instincts are present in the Extras, writes the astrobiologist Pushkar Ganesh Vaidya. It is possible that extraterrestrials have evolved differently from humans capable of violent aggression or peaceful compromise. It could be that humans encounter aliens billions of years more advanced than us, Shostak said in an interview. Aggressive aggression by aliens is preferred in the Darwinian system, but aliens may also be peaceful. The extent to which alien life curbs its aggressive instincts before destroying itself is a guess.
