Aliens! Aliens!! Aliens!!! We often hear about them and the space exploration for the discovery of alien life on other nearby planets. But each passing day, brings fourth no answer to quench our thirst for answers on where and how we can actually find alien life and then ‘scientific’ excuses to back it up.
Nevertheless, a phycist who goes by the name Enrico Fermi looked up into the sky, about 60 years ago and asked, “where is everyone”. He was talking about aliens.
Today, scientists know that there are millions, perhaps billions of planets in the universe that could sustain life. So, in the long history of everything, why hasn’t any of this life made it far enough into space to shake hands (or claws … or tentacles) with humans? It could be that the universe is just too big to traverse.
It could be that the aliens are deliberately ignoring us. It could even be that every growing civilization is irrevocably doomed to destroy itself (something to look forward to, fellow Earthlings).
Find Some OF The Reasons Below:
1. They May Not Be Detectable By Sound and Light Waves
In a small study, the researchers asked 137 people to look at pictures of other planets and scan the images for signs of alien structures. Hidden among several of these images was a tiny man in a gorilla suit. As the participants hunted for what they imagined alien life to look like, only about 30 percent noticed the gorilla man.
In reality, aliens probably won’t look anything like apes; they may not even be detectable by light and sound waves, the researchers wrote. So, what does this study show us? Basically, our own imagination and attention span limit our search for extraterrestrialsy. If we don’t learn to broaden our frames of reference, we could miss the gorilla staring us in the face.
2. Humans will kill all the aliens (or already have).
The closer we get to finding aliens, the closer we get to destroying them. That’s one likely eventuality, anyway, said theoretical physicist Alexander Berezin.
“What if the first life that reaches interstellar-travel capability necessarily eradicates all competition to fuel its own expansion?” Berezin wrote in a paper posted in March to the preprint journal arXiv.org. “I am not suggesting that a highly developed civilization would consciously wipe out other life-forms.
Most likely, they simply won’t notice, the same way a construction crew demolishes an anthill to build real estate because they lack incentive to protect it.” (Whether humans are the ants or the bulldozers in this scenario remains to be seen.)
3.The aliens couldn’t evolve fast enough (and died).
File another excuse under “the aliens are dead already” category. The universe may be teeming with hospitable planets, but there’s no guarantee they’ll stay that way long enough for life to evolve. According to a 2016 study from Australia National University, wet, rocky planets like Earth very unstable when they start their careers; if any alien life hopes to evolve and thrive on such a world, it has a very limited window (a few hundred million years) to get the ball rolling.
“Life may be rare in the universe not because it is difficult to get started, but because habitable environments are difficult to maintain during the first billion years.
4. The Effects Of The Dark energy
The universe is expanding. Slowly but surely, galaxies are moving farther apart, with distant stars appearing dimmer to us, all thanks to the pull of a mysterious, invisible substance that scientist call dark energy.
Scientists speculate that within a few trillion years, dark energy will stretch the universe so much that Earthlings will no longer be able to see the light of any galaxies beyond our closest cosmic neighbors. That’s a scary thought: If we don’t explore as much of the universe as possible before then, such investigations may be lost to us forever.
5. The Plot Twist
What if we’re the aliens? What if the aliens we’ve spent billions of dollars looking for, has been us all these while? What if the ‘real creatures’ found us ‘aliens’ first and has had us under surveillance for ages and has, in some way, been manipulating our politics, lifestyle etc? Scary right?
Well, in a nutshell, the hypothesis says that much of the life we see on Earth today didn’t originate here but was “seeded” here millions of years ago by meteors carrying bacteria from other worlds.
Proponents of this theory have variously suggested that octopi, tardigrades and humans were seeded here from other parts of the galaxy — but unfortunately, there’s no real evidence to back up any of that.
One big counterargument: If bacteria carrying human DNA evolved on another nearby planet, why haven’t we found traces of humanity anywhere besides Earth? Even if this hypothesis turns out to be plausible, it still doesn’t help us answer Fermi’s nagging question … Where is everybody?
