10 Reasons Why We Still Haven’t Met Aliens
According to the drake equation, there must be tens of thousands of alien civilization in our galaxy.
If they were hostile, we should have been wiped out long ago…So why we haven’t we encountered any yet?
10. Civilization cannot evolve a past certain degree
According to the great filter theory, some kind of barrier would prevent the rise of advanced beings based on the idea that it couldn’t avoid an extinction event due to natural or technological disasters. It postulates that any species reaching such levels of advancement is bound to disappear sooner or later.
9. They see dinosaurs
If an alien astronomer located 65 million light years away for earth looked through a telescope. He’d see earth during the cretaceous period, due to the time that light would take to reach his eye(s) with a powerful zoom and assuming that advanced aliens wouldn’t have developed batter methods. They’d see dinosaurs before their end, and would have no clue that intelligent life would arise here.
8. Advance ETIs
We have been left behind advanced ETIs may have invariably left the galaxy for greener pastures at some point in their history. According to John Smart’s transcending hypothesis, all move toward better areas of the universe that were not yet aware of. And progressively become denser, more efficient entities that eventually operate at the nano scale…black holes would be the ultimate destination for such beings to escape this space time continuum.
7. We have nothing in common
Gaseous or bioluminescent life forms could be so different that communication would be impossible. They might even have a sensory field reflecting a reality or dimension in which humans do not appear. ETIs can also be machines that have long forgotten how to understand the life preoccupations of meat….or ancient species who thrived for millions of years, and just have no point in interacting with immature civilizations.
6. Earth is special
Earth may not be the only one, as similar planets have already been found in our neighborhood. But distances are so great on a universal scale that chances are low for civilizations to connect…life supporting environments may also require too many perfect conditions, even on other earths.
5. Earth has nothing special
Contrary to the last theory, this one suggests that earth-like planets are so banal in the universe…and that life is such a common thing that ETIs cant visit each planet showing signs of intelligent life…recent findings back up this theory, as star systems were found to host multiple habitable planets…like gliese 180, kepler 62 and even our solar system at some period with earth and mars.
4. We live in virtual reality.
The new planetarium hypothesis proposes that ETIs of manipulating matter and energy…could easily create a simulated universe like ours, where matter and self-aware beings could evolve…the possibility of humans being AIs in a fabricated world is seriously considered by scientist…and suggests that we don’t see aliens because the universe has been engineered empty of other life.
3. They’re waiting for us
Maybe we just fail to see the signs, as they could also emit radio signals, but on another frequency…and even electromagnetic signals, gravitational signals, or a technology beyond our understanding…it is also possible that ETIs lift a beacon with a message somewhere for the time we’d be ready…that remains inaccessible to our current level of technological advancement…new theories say that the signs could be massive geometrical figures put on or around a host star.
2. We live in suburbs
We now knew that earth is located in a pretty quiet area in the outskirts of the Milky Way…and that is actually nothing that couldn’t be found abundantly elsewhere in the galaxy…then why would advance ETIs invest so much energy to visit an emerging intelligent life in such a place?
1. They’re watching us
advanced aliens may be watching earth from space or even walk among us, we just cannot see them…as such beings would have probably developed cloaking devices that were unable to detect…one of the best answers to the Fermi paradox, the zoo hypothesis postulates that they may observe us as a curiosity…or even study us as guinea pigs, maybe with the aim to have a better understanding of their own evolution?
