Why Can't We See the Evidence of Alien Life?
Somewhere out there in that vast universe, there must surely be countless other planets teeming with life, but why don't we see any evidence of it?
Well, this can be the celebrated question asked by Enrico Fermi in "Where is everybody?"
Conspiracy theorists claim that UFOs are visiting all the time and the reports are just being covered up, but honestly, they aren't very convincing.But that leaves a real riddle.
In the past year, the Johan Kepler house observatory has found many planets simply around close stars, and if you extrapolate that information, it's like there might be 0.5 a trillion planets just in our galaxy.
"If anyone in 10,000 has conditions that might support a form of life that’s still 50 million possible life-harboring planets right here in the Milky Way."
So here's the riddle. Our Earth did not form till regarding nine billion years when the massive Big Bang.
Countless alternative planets in our galaxy ought to have fashioned earlier and given life an opportunity to urge current billions or actually several countless years prior happened on Earth.
If simply a couple of of them had spawned intelligent life and commenced making technologies, those technologies would have had countless years to grow in quality and power.
On Earth, we have seen however dramatically technology will accelerate in only one hundred years.
In countless years, Associate in Nursing intelligent alien civilization may simply have displayed across the galaxy, maybe making large energy-harvesting artifacts, or fleets of colonizing spaceships, or wonderful works of art that fill the night sky.
At the terribly least, you'd suppose they'd be revealing their presence, deliberately or otherwise, through magnetic attraction signals of one kind or another. And however we tend to see no convincing proof of any of it.Why?
- Well, there are many various potential answers, a number of them quite dark.
May be a single, super intelligent civilization has indeed taken over the galaxy, and has imposed strict radio silence because it's paranoid of any potential competitors. It's simply sitting there able to obliterate something that becomes a threat. Or maybe they're not that intelligent. Or perhaps, the evolution of an intelligence capable of making refined technology is way rarer than we've assumed.
- After all, it's only happened once on Earth in four billion years.
Maybe even that was unbelievably lucky. Maybe we tend to be the primary such civilization in our galaxy. Or, perhaps, civilization carries with it the seeds of its own destruction through the shortcoming to regulate the technologies it creates. But there are numerous more hopeful answers.
- Maybe we tend to be the primary such civilization in our galaxy.
Only a small fraction of the celebs in our galaxy have extremely been checked out closely for signs of attention-grabbing signals. And perhaps, we're not looking the right way.
Maybe as civilizations develop, they quickly discover communication technologies far more sophisticated and useful than electromagnetic waves.
Maybe all the action takes place within the mysterious recently discovered matter or dark energy, that appears to account for most of the universe's mass.
Or maybe we're looking at the wrong scale. Perhaps intelligent civilizations come to realize that life is ultimately just complex patterns of information interacting with each other in a beautiful way, and that can happen more efficiently at a small scale.
"So even as on Earth, clunky stereo systems have shrunk to beautiful, tiny iPods, maybe intelligent life itself, in order to reduce its footprint on the environment, has turned itself".
