Bullshit meter is uncrated. Dear reader will note that the original
poster spewed 180 lines and managed to say nothing at all. "Sir
Arthur" has all the intellectual impact of a gay interior decorator
with a hangnail or a California governor abandoned by his own
political party. They both interminably whine while being forgotten
to death.
Science has a mathemtical model, testable new predictions thereform,
and scholarly literature citations to document the progressive
validity of supportive assertions, e.g.,

I am sick and tired of people complaining that one or another law of physics
would have to be violated by flying saucers, and, therefore, since I am a
nuclear physicist, how can I say some UFOs are alien spacecraft?
Bullshit meter's big banana plug is inserted.
There is a long list of such supposed violations: It would take too long to get
here from other star systems. It would take too much energy to get here from
other star systems. Right angle turns are impossible. High accelerations would
violate the laws of physics. People can't be taken through walls without
damaging the walls or the people. Etc. ad nauseum.
What we seem to be dealing with are claims by people who don't understand the
laws of physics, who have no comprehension that the feasibility of accomplishing
a particular objective is almost completely dependent on the engineering
assumptions made,
Bullshit meter's needle quivers.
and that much of the blind acceptance we give to today's
technology would have been totally rejected by other noisy negativists 100 or
more years ago.
It is easier and perhaps more erudite to suggest that something is impossible
because it supposedly violates the laws of physics rather than admitting, "I
don't know how to do that." Can we reach the stars? Can we withstand high
accelerations? Can we go into orbit? Can we make powerful computers that will
fit on a desk?
0.01 on the logarithmic bullshit scale. So far it's Liberal Arts cheap
dialectic and critique bullshit, not quality physical sciences blowing
hypersonic plasma out your ass bullshit.
Slide rules and vacuum tubes won't cut it for today's computers.
Noting that slide rules and vacuum tubes constituted the first
computers. Hello "Amazing Grace" Hopper! Computer lights are LEDs
not filament bulbs. BFD. Still 0.01 on the logarithmic bullshit
scale - pussy arguments.
Neither will
transistors nor integrated circuits. . . But micro integrated circuits will do
it. They were only attained with the expenditure of billions of dollars and
thousands of man-years of effort by physicists and others.
Fabs are engineering. They contain no scientists. You don't know the
differences among science, technology, engineering, production, and
Sales & Marketing. Still 0.01 on the logarithmic bullshit scale -
pussy arguments. Bulk parallel fabrication means each completed valve
has an infinitesimal value even amortized over the cost of the fab.
Each transistor in a CPU is of such small financial value that it is
beneath contempt to even consider it. The connection pins cost hugely
more.
The key thought is that progress comes from doing things differently in an
unpredictable way.
Christ, are you ever going to say something or will you continue
vigorously celebrating the picking of your dingleberries? Your real
parents were infinitely wise in going didi-mau immediately after you
were born.
Acceleration
How much acceleration can people stand?
Less than 2 gees for less than a week cumulative. NASA centrifuge
studies.
~40 gees as impulse in rocket sleds. Air Force studies by John Stapp.
~8 gees in a bad (is there any other kind?) Russian space capsule
recovery.
[snip whining crap]
Some have said that saucers making right angle turns violate the laws of
physics. The laws of physics say nothing about the possibility of making rapid
right angle turns. Our present jet and rocket technology, which work by carrying
along something thrown out the back end, is not capable of providing right angle
turns, because we cannot rapidly change the direction of the rearward thrust.
Automan in his Autocar. Painfully bad even as a TV sitcom. Still
0.01 on the logarithmic bullshit scale - pussy arguments.
A magneto-aerodynamic system which could provide rapid changes of the direction
of electric and magnetic forces probably could provide right angle turns. More
likely there is a technique about which we know nothing.
Bullshit meter hits 0.02. This guy couldn't sell fire and brimstone
to a storefront church filled with sweating Oklahoma hard shell
Baptists having their fields eaten by Mormon crickets.

Energy and time
I have been told that getting here from another solar system in a time shorter
than the average person's life span would take far too much energy and would
violate the laws of physics, or it would take thousands or millions of years.
The fact is that the feasibility of any space travel is based upon the
assumptions made.
Go ahead, finesse Special Relativity with an "assumption". Bullshit
meter hits 0.02. Common ignorance plus a fat dollop of common
stooopdity.
[snip more wandering crap]
Another misunderstanding of the laws of physics comes from people pointing out
that since one would have to approach the speed of light (670,000,000 mph) to go
to nearby solar systems, the amount of energy required would be humongus because
the mass of the rocket increases as one approaches the speed of light. However,
it only takes one year at 1G acceleration to get close to the speed of light.
If one uses nuclear fusion of deuterium (heavy hydrogen) and helium-3 (light
helium one produces charged particles which can be directed by electric and
magnetic fields) then there is ten million times as much energy per article as
they can get in a chemical rocket. The particles are born that way and are not
accelerated to that energy.
Hey stooopid, do the explicit calculations, "The Starflight Handbook,"
Eugene Mallove and Gregory Matloff. There are no real or extrapolated
sets of engineering circumstances - Bussard ramjet to a thousand
tonnes of antimatter neatly tucked under your tiny scrotum, that takes
you anywhere interesting in real time. The 8.78 lightyear round trip
to Alpha Centuri will kill you dead as a medically sterilized
syringe. If you go slow, cosmic radiation cooks you dead as you age
to death. If you go fast, Doppler-shifted cosmic radiation fries you
like a rasher of bacon.
In addition, time slows down for things moving that fast to the point that at
something like 99.99 % of light speed, it only takes a little over six months
pilot time (not counting acceleration time) to go the 39 light year distance to
Zeta l and Zeta 2 Reticuli.
Hey stooopid, the investors at home age at the normal rate. Nobody
will put up any cash. Nobody travels anywhere in this universe in
real time unless there is wholly new and unanticipated physics
reducible to practice discovered.
Also, if one uses gravitational assist (the traveler doesn't provide the energy)
as we do on all our deep space probes, the increase in mass wouldn't matter
anyway. A black hole would be quite convenient.
Idiot. "If we could travel thousands of lightyears in a flash to
arrive at a black hole, we could use it to travel thousands of
lightyears the slow way." BTW, git, black holes are rather dirty with
ambient radiation. You had best also correct for things a like
Lense-Thirring frame dragging lest you end up in places we'd all like
to see you go.
Moving through walls
"But Stan, how do the laws of physics permit people to be pulled through walls
and windows without breaking them or the person?" I haven't the faintest idea.
When you have nothing to say, don't.
[snip more crap]
Limited realms
Remember that the closest-to-each-other pair of sun like stars, Zeta 1 and 2
Reticuli, are a billion years older than the sun. An important aspect of the
laws of physic is that they apply in limited realms.
General Relativity, being a covariant tensor theory, is
backgroundless. It is the whole (classical) universe contained within
in ten equations.
[snip more crap]
What new realms will be discovered in the next decade or in the next century?
New variations on old theme of the world of physics?
After 180 lines of great boredom we arrive at... nothing. Bullshit
meter's big banana plug is de-inserted and wiped with a Povidone
iodine cleansing rag. Here folks, read something interesting,
