Experts differ enough
Reporters interviewed several leading experts in the field of astrobiology, to learn how you can actually look for potential aliens. It turned out that experts are quite different.
The survey was attended by several leading scientists from various space programs and research institutes. Interestingly, only a few respondents voiced similar versions, while as much of the opinions differs a lot.
So, President, international programs METI Vakoch Douglas (Doug Vakoch) believes that “alien life can exist in many different forms, which people may mistakenly confused at the species level.”
In addition, according to Wakka, people shouldn’t have hoped to meet in space aliens are similar in body structure and mind to us. On other planets, perhaps a countless number of random coincidences, each of which will play a role in the formation of alien life. And even the same scientific discoveries can come in different guise.
Another opinion Kathleen Ahrens (Ahrens Caitlin) from the University of Arkansas. According to her version, the life may look reasonable, even without being the same”. Besides, alien life can be based on a variety of chemical compounds, in contrast to terrestrial carbon”.
Senior astronomer Seth Shostak (Seth Shostak) of the SETI Institute suggests that “the most alien looking living creatures on Earth are insects, which during evolution have become incredibly diverse and have adapted to the environment”.
Finally, astrobiologist Rocco Monicelli (Rocco Manicelli) from NASA is of the opinion that “life in the universe is incredibly rare even the simplest single-celled organisms”.
According to his version, to meet reasonable advanced race from another planet, like Earth, is almost impossible to match the scale of the size of the universe.
