00:00You know what is one of the biggest mysteries of science and our universe?
00:04Why haven't aliens contacted us yet?
00:06It's a question that has fascinated humanity for decades.
00:10And now a NASA scientist may have a surprising answer.
00:14Dr. Robin Corbett, an astrophysicist at NASA's Gorbett Space Flight Center
00:18and the University of Maryland,
00:21presents a fresh perspective called the radically mundane theory.
00:26According to Dr. Corbett, extraterrestrials haven't reached out
00:29because they may have simply gotten bored of trying to find us.
00:34He suggests that alien civilizations might be only a little more advanced technologically than we are,
00:41a bit like having an iPhone 42 instead of an iPhone 17.
00:45In other words, they aren't god-like beings with faster-than-light travel or cosmic technologies beyond our imagination.
00:53Dr. Corbett explains that these civilizations may have reached the technologically limits
00:58of what they can do with exploration.
01:01Because sending out powerful space probes or signals across the galaxy requires immense energy
01:06and potentially millions of years to get a response.
01:10They may have lost interest and stopped trying.
01:14Imagine sending a message and waiting millions or even billions of years.
01:18The motivation to keep this up could simply vanish.
01:22He points to a nearby exoplanet Proxima Century B, located four light years away as a hopeful candidate for life.
01:30But at today's spacecraft speeds, it would take humans roughly 100,000 years to get there,
01:36a truly mind-boggling distance.
01:38This raises the question of how aliens could even hope to communicate or travel to other worlds
01:43when these distances are so vast.
01:46Popular culture over the years has painted a vivid picture of aliens as highly advanced,
01:51sending out swarms of robotic probes or blasting powerful light beacons across the cosmos.
01:57Movies like ET and Close Encounters of the Third Kind imagine slow-moving spaceships visiting Earth.
02:03But Dr. Corbett's research suggests that this is more science fiction than reality.
02:08Our cosmic neighbors may simply lack the motivation or ability to engage in huge projects
02:13like interstellar colonization or long-distance communication.
02:18This idea directly addresses the famous Fermi Paradox,
02:22the big contradiction where many scientists estimate the likelihood of alien civilizations to be high,
02:28yet we have no concrete evidence or contact with them.
02:31Dr. Corbett's radically mundane theory argues that there may be some technological civilizations
02:36scattered in the Milky Way, but none with the extraordinary tech
02:41to create easily detectable astro-engineering marvels or send enduring signals.
02:46Yet, not everyone fully agrees.
02:48Professor Michael Garrett from the UK warns that this theory might reflect
02:52too much of a human-like boredom onto the cosmos,
02:55doubting that all intelligent life would be so disinterested.
02:59There are other hypotheses as well.
03:01Some suggest that aliens find humans too dangerous to approach,
03:04while others believe that extraterrestrials have evolved into forms beyond our recognition.
03:11Even as scientists debate these ideas,
03:14Earth-based researchers continue to try contacting other worlds
03:18by sending radio and light signals, akin to sending emails across space.
03:23Physicist Mark Buchanan stresses that using light signals might be the best bet
03:28since they travel fast and remain unchanged,
03:32allowing other civilizations to recognize them as messages from intelligence.
03:36So, while we don't have aliens dialing our number yet,
03:39ongoing research and theories like Dr. Corbett's help us understand the challenges
03:44and wonders of cosmic communication.
03:46Maybe extraterrestrials are closer to us in spirit than we thought,
03:51or maybe they are just a little bit bored.
03:53Stay curious and keep looking up,
03:55because the universe still holds many mysteries waiting to be unraveled.
