But he's right. This newsgroup is full of fantasists who really think
we'll travel among the stars one day and interact with intelligent
aliens. Absolutely ludicrous.

We'd never survive even 1% of the journey to another star. Humans
aren't built for interstellar travel. And yes there are many aliens out
there, but the distances make it impossible to ever meet them.

Such a very important message, can't be stated too often.

Ahhh, but the distances do not necessarily make it
impossible for us to ever see/hear/receive a clear
message from them.

That would be a humanity changing time.

Possibly, but the vast distances still prohibit any kind of a usual
two way exchange.

You are really going to make them feel bad, is you keep talking that way.

Hillbilly claims need a lot of repeating because they are sooo often
proven to be b/s. In an infinite univere even the highly improbable
happens an infinite number of times and one of them could be us.

Why in the world are you even thinking of
"a usual two way exchange" ?

If we receive a clear unambiguous message from
some alien advanced life, it will take us years
to digest and analyze that fact.

Human life will be changed by just that fact.

In an infinite universe the distances are too vast for us to ever make
contact. Simple math.

Most humans are too dumb to grasp the size of the universe. If they did
they'd soon realize we will never make contact with anything as they are
too far away.

Asimov's "My Son, the Physicist" provides a much better solution.

Did you ever stop to think that the aliens were already here and LEFT,
totally disgusted.
And that they don't have any interest in talking to us. So they are not
answering their phone.

Only for a short period, until novelty wears off. Just like when we 1st
confirmed there were real exoplanets in 1995 so not just theory.

50 years ago if someone told you that you could get into an argument in real
time on something called an "internet" with people scattered anywhere in
the world.
Your answer would have been..........."No evidence" "Too far away, can't be
done"

Bit of a difference between boosting the existing telephone system and
traveling to stars or finding aliens.

Amazing how the whole point of this thread continues to be missed,
that distances are FAR too great for any practical travel between
stars, even in the very unlikely event of traveling near light speed,
or of any communications. All experience so far has confirmed this.

You mean,......SO FAR
It was not that long ago the same thought about being impossible was said
about beng able to travel at speeds of over 30 miles per hour......
Until it happened.

If I have missed the point that some people willl always refuse to believe
that limits are only something thet has not been figured out yet, then you
are right.

Wait until we discover that light actually can travel faster than "C", and
it's medium is actually the "stuff" we now wrongly call "dark matter".

Not everything we can imagine is possible. Sorry.

I seem to remember, way back when, learning that people were to walk out
in front of stage-coaches with a lite lantern. So that limited the
coaches to, what, 5 m.p.h.!

Neither. Google is your friend.

Modern physicists on the other hand are starting to doube that anything
is really impossible. Quantum tunneling e.g. allows particles to
pass through regions where they should not "possibly" be able to pass.

Bur grade school science book writers that claim "nothing can go
faster than light" are in the position of quoting physics that otherwise
allows two points in spacetime to be connected directly and allow
zero transit time. Or allow space to expand at any speed and drag
anything "in" it along for the ride.

But I guess that stuff is written for kids. Like when jr grade school
textbooks say you cain divide a number by a bigger number or
subtract a bigger number from a smaller number.

You're meant to figure out later that that was just a bit of simplifying b/s.
