LOL...thanks for the right word.


I was 7 at the time, so I didn't have a word for it then. But yeah...cloaking.

Douglas Adams, RIP. As the dolphins left the Earth they said, "So long, and thanks for all the fish!" Sure, I'll be happy to reward your claim with a virtual gift of five pounds of fish. Consider it done. Never mind the stench, they're just fish - SurstrŲmming.

l think there must be, especially lately with all the new stuff they've been finding up there.
l tend to think though too that the idea of us being the only ones here or out there would have to be incredibly arrogant and naive.

Let's say the Alcubierre warp drive is technically possible. It appears lots of "exotic matter" would be required to fuel it. Further suppose that there is some way to create large amounts of this "exotic matter" without requiring the mass of a Jupiter for a single flight (which would mean we could do a few FTL trips before we exhausted all the available mass outside the Sun in our system). I suspect this is one of the major reasons no one's here -- FTL travel is terribly difficult and prohibitively expensive for it to be common or frequent. But put that aside for the sake of argument -- what are the other stumbling blocks that might make it highly unlikely that we're being visited by advanced aliens from elsewhere?

There have been five major extinction events in the history of life on Earth:

Ordovician-Silurian 444 million years ago
Late Devonian 370 million years ago
Permian 252 million years ago
Triassic-Jurassic 201 million years ago
Cretaceous-Tertiary 66 million years ago

Any technological society that might have been around for one of these events would have been doomed. Major causes were: asteroid impacts, major volcanism, and (possibly) gamma ray bursts. It's been suggested the primary driver behind such events is volcanism. We know that volcanism occurs on several other bodies in the solar system beside Earth. If there'd been another event a few million years ago, it's likely we wouldn't be here today speculating about intelligent life elsewhere.

There are other hazards that face the young technological civilizations. In the 1850s, a major solar flare event fried telegraph wires across the United States. A similar event today would likely destroy Earths economies and wipe out much of our technology (satellites: gone; power grids: gone; communications: gone). Climate change, whether anthropogenic or not, is also a hazard -- another major ice age would likely cause major problems for our technological civilization, and play havoc with our ability to feed people. Then there's our tendency to blow each other up; I won't be surprised to see a nuclear exchange on the planet in my lifetime. Limited nuclear war would wreak financial and technological havoc on our civilization.

How about our monoculture crops -- all it would take would be a mutated virus wiping out our crops to make us go the way of so many other vanished civilizations. Or new plagues that are antibiotic resistant due to our fondness for using antibiotics every time a cold comes along.

Then there's the economic argument: what would a civilization stand to gain by expending huge amounts of resources to come here?

Here's my guess: there are several advanced technological civilizations in the Milky Way, but it's too expensive and difficult for them to come here. Plus, there are a lot of stars in the Milky Way; chances are good they don't know we're here (and will never know before one of the causes I've listed above wipes them out). There are a lot of pre-technological civilizations out there, and a good number whose technological development is equivalent to Medieval or Victorian eras on Earth.

As I said, I believe there are aliens out there -- but we won't be hearing from them before the universe or their own hatred and greed wipe them out.

If they had anything to do with the way we evolved, they may have screwed up royally.

This is what I always thought. Also, a burned out star doesn't mean there isn't life due to that star during it's own life. The life could have escaped before their star burned out.

Just think.
lf only they'd made such a mess of their planet and civilization as we have, blowing each other up and setting of bombs all over the place, wrecking their planet, filling the atmosphere with space junk and pollution, we wouldn't even need telescopes to find them in the first place.

I hate to say yes but I certaintly canít say no. Iíve had at least three UFO sightings some very strange dreams but more signfigantly an early childhood filled with high strangeness that made me question my sanity humanity even my true age. So I canít and wonít poo poo someone elseís paranormal experiences, whether they are abductions alien contact or whatever, itís not my place to say yea or nay but if Iwant to learn I should listen with respect and compassion.

Default Yes I believe but...

Yes I believe sentient creatures of some sort not only exist Ďout thereí but right here on this planet in fact theyíre are probably much closer than we think. If they are on another plane of existance then they well could pop in and out of our minds at will, heck we donít even know what we are, what are minds are, maybe we are all portals.
Iíve had a lifetime of strange occurances. My childhood was filled with visions memories highly inappropriate reactions, so much so that even way back then I found myself questioning my sanity humanity even my true age. Point is you see what you see if others havenít seen havenít had strange experiences then they just donít know, but they have the right to express theyíre doubts.

I guess the question is are they truly aliens,could it be what we call reality is just a our small corner of a much greater reality all beings share. Accessibility could be the issue, maybe they have greater acccess to us than we have to them maybe they use our minds they same way we use doors in house, but we all live in the same house.
