Since the birth of philosophy, we’ve never stopped wondering about the answer to the question: Are we alone?
Neil deGrasse Tyson tackles the possibility of the prevalence of life in the cosmos by comparing our sole data-point we have, life on Earth. He points to the fact that life on Earth formed as soon as it had a chance after the late heavy bombardment period.
Neil deGrasse Tyson also extrapolates from the fossil record that Intelligence as we humans have defined it is not necessary for survival, therefore intelligent life in the cosmos might be extremely rare.
In the summer of 1950 Italian-American physicist Enrico Fermi, while walking to lunch with his fellow physicists was having a casual conversation about recent UFO reports and the possibility of faster-than-light travel. Allegedly Fermi suddenly during lunch said, “But where is everybody?
This later became known as the Fermi problem or paradox. Which is the apparent contradiction between the lack of evidence for extraterrestrial life and the high estimate probability for their existence.
So what could possibly explain this semblant paradox?
Whatever is preventing non-living matter from undergoing “Abiogenesis” in time, to expanding lasting life as measured by the Kardashev scale, in the context of the Fermi paradox, is known as the “Great Filter”.
As NASA has explored our solar system and beyond, it has developed increasingly sophisticated tools to address our endless curiosity for the possibility of life existing elsewhere in the cosmos. Within our solar system, NASA’s missions have searched for signs of both ancient and current life, especially on Mars and soon, Jupiter’s moon Europa. Beyond our solar system, missions, such as Kepler, are revealing thousands of planets orbiting other stars. Fueling our imaginations further with bewilderment, wondering if there are other civilizations out there, perhaps asking the same question. Are we alone?
A growing number of people believe we’ve already answered this question due to recent UFO reports over the last few years. However, eye-witness testimony and ambiguous video footage does not qualify as extraordinary evidence to definitively answer this age old question. But to be respectful to the people who believe we’ve been visited by extraterrestrial crafts, we will dedicate a whole video on the topic.
