But humans have been reaching out and sending signals into deep space in search of extraterrestrial life. You must have heard of SETI and the Allen Telescope Array? |
Yes, but even though we've been searching for decades, we have not found any signs of intelligent life.
How many crafts have been sent out from earth into deep space with detailed instructions of who we are and where to find us? |
Voyager 1 is the furthest man made probe. It just recently (2 years ago) exited our solar system... and it took about 40 years for it to get that far. And it's only expected to run for another 10 years before its generators finally fail, so it's not likely to make it much further (though I guess it will become space debris and keep drifting)
So yeah... all that time and we just barely escaped the solar system. The thing is... our solar system is
microscopic compared to the size of the universe.
Maybe you fail to grasp just how big the universe is. It's freaking big. It's mindblowingly big. Think of the biggest thing you can think of... multiply its size by like a million... and the universe is still way bigger.
- There are 8 planets in our Solar System
- There are ~100-400 billion solar systems in the Milky Way galaxy
- There are over 54 galaxies in our Local Group
- There are 10 Groups in the Virgo Supercluster
- There are millions (~10 million) superclusters in the observable universe.
If our solar system is typical, we can expect there to be 8 * 250billion * 54 * 10 * 10million other planets in the observable universe.
That is... 4.32e19 planets.
That is... 43,200,000,000,000,000,000 planets
So not only are there tons of planets out there... but they're all
really really really far apart... so searching all of them is nontrivial.
EDIT: To put this into perspective even more.... if your species is a
trillion years old and you were able to search on average a
hundred planets every year... you would have searched 0.00023% of all the planets.
For even more perspective... our species is several million years old, and in all that time we have searched exactly 7 other planets (and not even thoroughly -- we're still looking at Mars)
/EDIT
And this is completely ignoring moons and other heavenly bodies that may be capable of supporting life.
And that's just the parts of the universe that we can
see. It might be even bigger. And if there are other universes (which there probably are), then it's even
bigger.
My point here is that, without more, the situation might be as hopeless as you describe, but a whole lot of money has gone into searching for life out there. In effect it is as if we have lit a smoke fire on that beach you mention, so anyone flying nearby can see that something is down here. If the search was hopeless, why do you think people would have invested a shed load of money into it? |
Because searching for extraterrestrial life is not the only purpose of these programs. They're also contributors to space exploration.
Space exploration has a lot of benefits for advancing the scientific frontier. And hey.. while we're at it... why don't we also look for alien life?
I can promise you that no serious project was ever funded on the sole principle of finding alien life. They were all bundled with other aspects that made them more appealing.
Yes, it is perhaps an extraordinary claim to make that aliens are conspiring with certain people but it might just be true. |
Extraordinary claims require extraordinary evidence.
You have yet to offer any.
It might also be true that if you can get your entire head into your own urethra, you'll start crapping out diamonds. But I'm not going to just assume that's true.
Sometimes in life you just have to go with your gut instinct. |
Favoring gut instinct over rational thought might be the very definition of "stupid".
Don't get me wrong... instinct definitely has a role... but replacing logic is not it.
Let me ask you another question. How would the world be different without these alien oppressors?
EDIT: also... to use your own point against you... why would our government spend all this money on searching for alien life when we've already found it?
