Ever since Avi Loeb Professor of Science at Harvard University said that he believed in the existence of aliens, the world was in an uproar. The reason is, you could say that only a handful of scientists have the courage to vocally express their beliefs about aliens to the public.
"A quarter of all stars host a planet the size and surface area of Earth. It would be arrogant to think we are alone," he said, as reported by The Guardian.
Loeb thinks that a scientist should open a dialogue with nature, not a monologue. Sometimes, nature can display or code differently from our thinking. Scientists have to be prepared for that.
"I found a few instances where the data gave us some anxiety, when the evidence didn't match what we expected, I felt this was the most exciting moment. Nature tells you, 'Your thinking about this is wrong,'" he said.
This is proven and applied by himself. Loeb is noted as the person who dared to speak out about the comet Oumuamua and thinks this object seems unusual. Loeb said he was not alone, in fact there were a number of scientists who also considered the comet's strangeness -- but did not dare to speak out.
So, what is the reason scientists don't want to talk about aliens or UFOs? This is because the issue is still taboo. There is an assumption or belief that discussing and discussing this matter can jeopardize their credibility as scientists, and their careers are in danger of aground.
In fact, there is nothing wrong with this. He insists that many scientists have the courage to theorize about other things like the multiverse (which is also often debated), but why not aliens or UFOs?
"What I mean is, how dare scientists shy away from this question, when they have the technology to answer it, and when the public is so interested. Meanwhile, at the same time you have theoretical physicists talking about extra dimensions, string theory, about the multiverse," Loeb said. .
