I have already come up with a new hypothesis in physics. Yet, I have
already physical explained (physical justified) 12 phenomena using
this hypothesis.
1) Calculate the gravitation inside a thin-walled hollow spherical
shell. Post it.
2) Calculate the electric field outside a coax cable. Post it.
3) A space ship continuously accelerates at 1 gee. Calculate the
time elapsed from initiation until internal steel struts with
cross-section 10 cm^2 and tensile strength 60,900 psi are pulled apart
under their own weight. Post it.
BTW, a high school kid can do #3 in less than 20 seconds, in his head.
20 seconds? Try 2. The answer, of course, is either
"absolutely never" or "no, it collapses immediately" :-)
(Assuming that the 1 gee is proper acceleration in free
space, as opposed to externally measured.) I'd have to
do a little more research to figure out exactly which --
but the Empire State building has 60,000 tons of steel,
as well as 200,000 cubic feet of Indiana limestone and
granite and a few other things. The official website
claims 365,000 tons total, or 305,000 tons of other stuff
supported by that 60,000 tons of steel.
Clearly, the building is supporting itself nicely. On the
Moon or in deep space one could make it even bigger,
though there's probably little point until we can sell
real estate therefrom.
Unfortunately, there's no indications of what the beam
size is that I can readily find, though it's large enough
for workers to sit and have lunch on.
Since the size of the spacecraft is unspecified, I can't
go much further, though one can attempt to use existing
spacecraft such as the Space Shuttle -- which isn't
nearly as tall / long as New York's architectural wonder,
which depends on orientation; nose-to-tail is 122.250 m;
wheels-to-tail is 56.000 m; Empire State is 381m high.
The Saturn V is actually *smaller*: 110.6 m tip-to-tail.
One can also suggest hypothetical spacecraft, such as the
alien mothership on ID4 (550 km diameter, 1/4 M_moon =
1.838 * 10^22 kg -- if one assumes spherical this gives it
a density of 211 kg/m^3, but I'll admit I don't remember
that detail offhand) or various constructs imprecisely
described in Fred Saberhagen's _Berserker_ series as
being spheres tens of km in diameter.
Of course, such have yet to be built Earthside except as
digital computer models.
As a side issue, one might run out of fuel well before
"absolutely never", even if one has a theoretical engine
on the order of an absolutely perfect hydrogen-boron
fusion type. :-) (Do the Berserkers, the ID4 aliens,
and the humans have a convenient source of antimatter
purchasable from Rotten Zalbie's?)
And then there's issues such as rusting, which are probably
well outside high school physics. One might hypothesize
"paintbots" -- the Golden Gate bridge in particular is
always being painted, though by humans.
