Who or what created us? Where do we come from? Where are we heading to? What is the meaning of life? Is there any objective meaning for life? Is there a divine being who created the Universe? What existed before the Big Bang? What even triggered the Big Bang? All these are great questions that humanity hopes to someday find irrefutable answers for. But perhaps the even bigger question of all is this: are we alone in the Universe?
Common sense and the discoveries of how unimaginably vast the Universe is are both telling us that it’s practically impossible for life to have been emerged only on Earth. Therefore, the even better question should be “When will we encounter aliens?”, rather than asking if aliens exist or not.
It might take a lot more than expected
Astronomer Sara Seager comes to shatter our dreams of encountering aliens any time soon. She has been speaking at the International Astronautical Congress in Washington during last month:
It’s probably something that’s going to be a slow discovery, not like the little green humanoids arriving here on Earth scaring everybody,
It’s probably going to take a long time.
Sara Seager is a professor at MIT, and NASA’s Transiting Exoplanet Survey Satellite (TESS) deputy science director, so she might know what she’s talking about. TESS even announced that it would team up with the Breakthrough Listen project for the search of alien intelligence. This may be a huge step for mankind, and it’s good to know that astronomers are not giving up and still hope to find aliens. Luckily for us, the Universe is way too big, so we have plenty of places to look at.
Last month, former NASA scientists stated that the space agency had found evidence of life on Mars about half a century ago. NASA denied the claim.
Hopefully, we will find out someday if we’re alone in the Universe or not. The truth is, both hypotheses are equally frightening.
