they'd probably just take one look at us and run for the hills ...
thats my opinion though.

they could, for all we know of already made contact ... heck theres enough people out there who think theyve been probed by ET at this stage ...

if they can master interstellar travel then its also highly likely they can shield themselves from our ability to detect them.

ET would most likely be totally un-interested in our society, more our art and culture.

I am selling ET-related death and mayhem insurance. Double indemnity if the cause of death was from an invisible ET. I will even refund all of the premiums if you meet your end from an extra-terrestrial hominoid who traveled here via faster than light space ships==but once again only if he and his ship are invisible.

Please contact me if you would like to have a franchise for this or, carbon offsets, birth control devices in the Virgin Islands, Rapture and apocalypse insurance, Indulgences for time -off in purgatory and Limbo are also on sale. Let me know !!

I am laughing: but here in Tennessee, Oprah Winfrey's father, a barber who is also a city councilman in Nashville, proposed that the City construct a UFO landing site to accommodate Alien craft. He and Oprah's mother each used to live in my subdivision (separately)

I'd like the insurance against anal probing. BTW whats with the anal probing. and why abduct people that don't like anal probes. why not pick someone from the porn industry. Or someone not opposed to having probes jabbed into orifices

Virgin Conception,

It's been a long time since that's been done well also.

Any one knows what is the estimated number of stars within 100 lightyears? Has to be many milions, so the probability of inteligent life could be good. Water is the perfect solvent for life, and water is prevelent throughout the our galaxy.

According to this there are about 2 000 stars within 50 light years so 100 light years multiply up to about 16 000.

All watching our 1960's TV. They'll be about up to the Apollo moon landings by now.


so 100 light years multiply up to about 16 000.

That's likely the limit before TV descends into the galactic noise...


I gave up watching TV long ago. I suspect that when video-on-demand becomes widely available, that will radically reshape scheduled broadcasting...

And then our TV signals eventually will no longer pollute our interstellar neighbourhood! (Utilising the internet rather than using radio broadcasts.)


That still leaves our pollution signature in our atmosphere to give the game away since about 200 years ago...

actually they still will. We forget that even cable television relies on satellite feeds. Doubt it? drive by your local cable office and have a look around back. You'll see some very large satellite dishes used to receive their feeds.

So those idiotic cable commercials whining about how satellite tv blah blah blah. The same goes for cable. The big difference is if the signal goes out you don't know if its at your house or somewhere between your tv and their satellite dish

I remember seeing an estimate of a much lower number of main sequence, non-binary stars out to 100 light years. Maybe less than 600.

What do you all find ??

The poster asked how many stars. Not the type nor wither or not they had companion stars.

There are 130 or so Sol like stars within 50 light years so that would put the number out to 100 light years at rougly 1000.

[edit]

Stars within 100 LY sorted by spectral class

B 4
A 76
F 303
G 512
K 947
M 2026

So, about 1762 of the most-likely-to-be-life-friendly F, G and K types.

There is a brown dwarf at about 7 lightyears. Its temperature is 25 C, quite pleasant. News from NASA.

It is a Y type star, the coolest in the sequence OBAFGKMLTY from hot to cool left to right. Astronomers used to memorize the sequence with the phrase O Be A Fine Girl Kiss Me (Paolo Maffei in "Beyond the Moon" ,MIT Press). I don't know the acronyms of the three final letters. Could it be Love To You? Help.

The three types after M used to be RNS. The RNS was Right Now Sweetheart.

If there is any truth in the Old Testaments Ezikial saga, they have known we are here for many millennia, and have yet to blow us up.
But looking at what we actually live on, and what is near by, but not liveable, finding, another livable brick might be rather hard, like few and far between.
But regardless of who thinks what, the primary objective of our species, is basically get off this planet because of a very unhealthy future.
I really don't think it matters much what is out there or where as long as we can get on it.
But who bothers about our future, which it seems, is limited to about a million years before the lack of a moon creates a very unstable platform for our survival.
It will not bother me, or you, but someone in the future might get the shakes. If we are still here.

Oooer... Don't say that! You'll have the red-x gang tearing down the thread!

Oooer #2... Have we not already jumped off the rails of the OT Guidelines?...

Maybe from our perspective assuming every life forms and intelligence sources from only water or carbon based beings might be too naive. Well many theories suggested about other chemistry based life conditions.

Through diversified carbon molecule dominances there are diversified carbon lab planets likely support different life forms thus diversified intelligence approaches could evolve.

Carbon based life makes more sense, carbon is a common element throughout the universe; sillicon based life is possible, albeit, sillicon is not as nearly common as carbon.

In Egypt in a burial crypt, from the 2000bc era, dug up in the 1880's, on a lintel over the entry door is a carved side view of a helicopter.Who flew choppers then, like 3000 years ago.
And in the 1960/70's a scientist from NASA actually did a bit of research on Ezikiel's "space vehicle" and while it can be built in current times, it cannot be flown because of the lack of a suitable driving force, ie reactor. We are well behind the owners of that vehicle.

Do some reading on the "helicopter" and you will find out that it is a glyph that got blurred over the ages.

It's generally believed that people are applying familiarity with today's objects with what was drawn then. Sort of like how some people will try to re-interpret the Bible with today's knowledge and insist that's what the original authors meant.

I could do the same to Moby Dick, but that doesn't mean the author had any omniscient knowledge of the future because I interpret it a specific way.
