The Fermi Paradox - Why we haven't been contacted by aliens

Actually we just want to be sure the great filter is behind us. Many more advanced civilizations than us does not ensure that.

Mostly because they're just way too far away.

When I had to take a world religon class I multiplied the two independent probabilities for earth planets(number of known earth-ish exoplanets currently seen divded by total planets) and the probablility that a living life form has abstract cognitive abilities (humans are the only known living thing with this talent) and the probablility came out to .00000000000000000000002 chance that you could be a living organism on an earth like planet with the ability to do abstract thinking. All things considering Einsteins theory of spacial relativity and breaking the speed of light I'd say it's highly unlikely that there's aliens perusing around our solarsystem. Not saying it's impossible, but when I'm doing the math here it just seems a little ridiculous.

i like it... agree to your work above..

I think teleportation is highly likely for goods in 50 years and humans within 100 years. Thats a doable tech. No warp drive needed.

What makes you think that a beam of particles can travel any faster than the speed of light? The same limitation still applies.

IBM theoretical physicists way back in 1993 were saying its possible. In the late 90's they successfully teleported photons. The key in the quantum mechanics was to disrupt the particles before teleportation to get around the Heisenberg uncertainty principle. Without it the math and data storage to do the quantum theoretical calculations would make it impossible.

We are doing it successfully now with particles. We have found a way around Heisenberg principle. So yes, I think its possible.

I'm not going back to look, but did anyone, anyone at all, give any serious thought to Lt. Col. Charles Halt and his men who witnessed and even touched et aircraft?

Or was it swept under the rug of pessimism like everything else?

Curious, but not worried, trying to get the message out is a thankless deal, most people are just too smart for their own good.

I find these things interesting, but don't necessarily view them as absolute evidence. I think our own government probably has secret stuff that they test all the time. A rank and file military guy or civilian could easily view them as something not of this world. These sightings may be alien and I'm open to that, but they may also be terrestrial and that's probably the more likely bet. I'm not sure there's any way to tell.

It's kind of funny now that I think about it. Faith in UFOs is similar to faith in religion. You either think it's true or you don't, but there's really no way to prove it unless the being in question shows up and announces their arrival.

wow I just read thru the whole thread and i'm glad people found this article as interesting as I did.

I really don't know what to think tbh. the math says that there's no advanced alien life form out there but then on the other hand you've got thousands upon thousands of first hand testimonials and if you think about it a civilization that's billions of years more advanced than us, you've gotta think they've found out ways past conventional physics and developed flight speeds and technologies that we can't even comprehend.

I like thinking about it

The great filter may have already happened for mankind. There was a genetic bottleneck some million years ago or so where it has been estimated that less than 1000 individuals of our species survive some event. That's cutting it pretty close.

I remember seeing an article about that. It's amazing to imagine an earth with 1,000 humans on it.
