This extremely important message can't be stated enough :

What part of : Distance = Speed x Time , don't people understand ? !

Even at speeds approaching light speed ( very unlikely in any case ) , interstellar distances are still way far too great !


Why thinking of interstellar travel?
The UFO or more correctly UAP (unidentified aerial phenomenon) could
come from the Earth itself.

I agree the "mostly likely" interpretation of the data at this point
is a bunch of "aliens" that seem a lot like humans. Maybe they have
interplanetary capability but they seem hang out in obscure parts
of the earth "a lot" of the time.

But interestingly the "space warp technology" some physicists argue
UFO's exhibit from time to time (e.g. "shape shifting") is a potential
FTL drive.

Warp drive uses the same part of General Rel that allowed the universe
to expand to ~100 bn LY diameter in 13 bn y.

An aquaintence from Harvard has been working on the detailed math which
was roughly worked out decades back (I thought).

It got me thinking and maybe it is a key point. If you can make
the local structure of spacetime bend even a bit not only can you move
from A to B without actually travelling through space (so no FTL problems)
but it might also explain the "walking through walls" stories,
being able to withstand huge pressures at the bottom of the sea
(i.e. make your ship look like a flat plate to the sea water ,
even travel through solid rock underground, in and out of volcanoes (if you
can make yourself appear flat or small then no heating problems --
square cube rule), and probably many things I havent thought of.

These concepts are science fiction with no comprehensive basis in fact and certainly never demonstrated or obserned in any way.

There always has to be at least one "nay-sayer"??

casagiannoni (various nyms)says the universe has not been observed in
any way and probably does not exist.
Who is to say just this one time he didn't guess wrong?

The radius of the observable universe is therefore estimated to be about
46.5 billion light-years and its diameter about 28.5 gigaparsecs (93 billion
light-years, or 8.8?1026 metres or 2.89?1027 feet), which equals 880
yottametres.

Wasn't that situation explained away by postulating that the speed of
light used to be a heck of a lot faster than it currently is .... you
know, how things tend to get slower as they age??

I don't know if the "different speeds" idea is still an idea
that physicists back. It may be superceded. It was around before
the "modern cosmology" that explained how the universe could be so big,
with an origin so recent ("only" 14 bn y) and look about the same in all
directions. Parts that are in opposite dirs and now far apart seem to
have the same temperature so how could they have communicated their
temperature to each other even at an early stage of the universe?

The current operating theory is that not only did the things in
the universe expand away from each other and the singularity that
was the Big Bang, but that space itself expanded ("inflation") and
space doesn't have even a Relativity-induced speed limit, only things that
have to plod through it.

Inflation in early universe
In physical cosmology, cosmic inflation, cosmological inflation, or just
inflation, is a theory of exponential expansion of space in the early
universe. The inflationary epoch lasted from 10 -36 seconds after the
conjectured Big Bang singularity to some time between 10 **-33 and 10 **-32
seconds after the singularity.

"way far to great" for what?

So, since 'casagiannoni' can not state what he believes
is possible, or what is not possible. He just keeps repeating
his very limited beliefs.

It seems he does not believe that any life in
any other star systems exists.

That is sure myopic
(myopic \mye-OH-pik\ adjective. 1 : affected by myopia : of,
relating to, or exhibiting myopia : nearsighted.
2 : lacking in foresight or discernment : narrow in perspective
and without concern for broader implications.)

It sucks to be closed minded.

Despite my asking on several occasions, he has refused
to state his opinion on the 'Starglider' concept,
that accepts limited speed of travel.

Is 'casagiannoni' even actually able to read?

Rubbish!! casagiannoni *knows* FTL travel is not possible!! No "if"'s,
no 'but"'s, no "maybe"s! He says it is not possible ... so it is not
possible, and the sooner we 'sensible' people realise this, the better!!
