Has Bowmann ever written a post with a line that reaches the end of screen, and wraps down to the next line? I don't believe so. Some of his posts consist of multiple lines, but they're the result of hitting 'enter'.

Hmmm. In physics light waves from the sun are considered to be parallel, or as neear as damn it. is it the distrance from the sun that they actually converge at?
define which light waves you are talking about, the light from the
sun goes off radially from the sun, as if they were a billion lasers
all pointed away from the sun but one end of each laser beam starts
at the center. They fan out which is another way of saying the
light falls off as the inverse square of the distance. At one unit its
say, 100. then at two units the power falls to one fourth, or 25 power
units and at 5 units distance it is 5X5 inverted or 1/25 th of 100
or 4 watts, and so forth. so the gist of that is these light beams
are anything but parallel. What you may be thinking about is
what Einstein found out, that mass near a path of light bends that
light path a little bit, in this case a laser beam just skimming the
surface of the sun bends by about 1.7 arc seconds angle.
Using that number, see if you can figure out where two laser beams
would meet, say one laser beam skimming by the north pole of the
sun tangentially and another skimming the south pole tangentially,
in other words two laser beams that start off parallel but happen to
be 880,000 miles apart then skims the surface of the sun and
Einstein says and it was proven that the beams bend by that 1.7
arcseconds of angle. How far away from the sun would they be when
the two beams meet? simple trig problem.

of grand vision of energy in our part of the universe, its actually
kind of awesome, this sphere we can't even see.
Originally posted by jimslyp69Its a bit much to put in this post for sure. Here is the short version:
You better point it out to me then.. I have no way of figuring it out.
The two laser beams will meet about 54 billion miles from the sun.
That is the focal point of the gravitational lens, but only the
first focal point. If you move the laser beams I mentioned earlier
out from the surface of the sun, tangentially the focal point is farther
away so there is in fact a focal line to this affair. If you take light
from Sirius, there is a focus of that light in a kind of searchlight
on the opposited side of the sun from Sirius and also from every
other star in the galaxy. They all have focused light in a streamer
of searchlights all starting at the 54 billion mile distance.
If you think about it you see a hidden stream of focused energy
from every star in the universe, so its a kind of movie screen of
all the energy passing this way, including neutrinos, radio, xray,
protons, matter, etc all bend to the tune of the local dip in
the curvature of space. Its an awesome thing to think about, if
we only had a craft capable of going that distance, about
1000 AU, you get free gain if you have a telescope or radio telescope
and can even power solar sails by riding the most powerful of the
beams. Remember I mentioned the earth is bathed in 13 megawatts
from Sirius directly, imagine the amount of energy in ITS like of
focus, GIGA watts just streaming by for free, a river of energy
just waiting to be tapped, used for propulsion, for power generation
for a spacecraft, etc. One other aspect, these beams can deflect
comets a bit from their regular orbits in the Oort cloud and cause
them to stream into the central system and create havoc by
crashing into various planets and asteroids in the inner system.
There is so much more I don't have room to tell here, you might
come up with your own ideas. Thats the 50 cent tour anyway.
Originally posted by THUDandBLUNDERWell not exactly, its only an energy focus. The gravitational lens
So an alien viewing the Sun from another star doesn't see the Sun as it is, but sees a mirrored and inverted image?
In fact, when we observe other stars we must also see mirrored and inverted images of them?
has been used by astronomers to see galaxies way off being
magnified by another galaxy inbetween it and the earth. When
the three are lined up perfectly, it produces what is called the
Einstein Ring. Here is a link to gravitational lensing in general
relativity: http://www.iam.ubc.ca/~newbury/lenses/research.html
You notice in this article, the concept is only used for galaxy-galaxy
lensing. The lensing I worked out (not very original concept, actually)
is for our sun but I extended the idea to other suns and found
among other things, if you take the case of Alpha Centauri,
light from AC forms a "searchlight" almost exactly the same
length as the distance to the star, 4 light years. So there is
a streamer of light on the opposite side of AC focused by the sun
that goes on for 4 light years and another on the opposite side of
AC that represents light focused by AC coming from the sun and
also 4 light years long. I am trying to find someone to help me
make a graphic of the whole effect in a three D image of a couple
of dozen stars in our neighborhood, so far no luck on that, want
to write it up officially, it hasn't been done by anyone yet, this
aspect of gravitational lensing has not been figured out by anyone
but me so far, so I am sort of letting the cat out of the bag but
when I write about it I usually get more ideas so I am not too afraid
of someone publishing before me. Try to visualize what the energy
is doing on a stellar local scale, its an amazing visualization.

My hats off to anyone who gets this one.
There is a sphere centered on the sun, (like Sol, our own star, ok?)
the diameter of this sphere is over 200 billion miles across.
What is it? I won't give hints now, but if everyone is stumped, I
can give some.
Originally posted by iamatigeryes to the first, no to the second. Although objects going slow enough
Guess: The distance at which an object would be gravitationally attracted towards our solar system tather than towards anything else?
can be captured by the sun at distances farther than 200 billion miles.
And it is the 10^9 version. The 10^12 version would be approaching
a light year in distance. One light year=5.8X10^12 miles (5.8 trillion).
just look at the previous post, the long one on gravitational lensing.
