capturing light information

if i have a telescope and i take a picture though it of the
sky at
night,i can look at that image on my computer and zoom in
to various locations so far before the pixels become large
and offer little information.

but in the future do you think perhaps it could be possible
to take a picture of the sky at night and sample light as it
really is.? ..So that we can zoom zoom zoom zoom to any
solar system that is available on a machine at a later time?
,so it would be an exact replication of the light that hit
the lens? can we store light perhaps in a thing like the
large hydron collider !!? capturing the light maybe using a
lense in space made in 0 gravity and storing the light
information in a lhc?

I don;t understand what you mean and I don't like science,
but it sounds interesting.

Who knows what the future will hold?

lmfao surely this is the Sample Frequency thread all over
again :P

The fact that (expensive) software image synthesizers will
already do things like this means that your suggestion is
almost useless. CCDs already have better efficiencies than
human eyes. I'm not great on imaging, so that's all I've got
to say, but you can already achieve pretty high resolution
with (very expensive) equipment today.

P.S. obviously image synthesis is totally approximation
based, so I guess it's not that accurate at all.

as soon as i speak of resolution people say my 6 mega pixel
camera if fine for me i cant see pixels! . fair enough but
what about zooming in and reframing? it would be so cool to
capture the light perhaps before it hits a focal lense
exactly as it is at that point in time. so that anyone with
a capable machine can examine that sampled light anytime in
the future... like google earth maping but instead with
actual light particles light can be stored in a vacum it
travels very fast ...but it is stored for billions of years
maybe there is a way to use space itself to store light.?

in the future I hope that we have 3D or 11D =D map of
universe. Mathematcal algorithms would predict universe
status, and observation than will be elective, partially.

So freqys dream is very probable.

wouldn't you need a lens to capture very tiny portions of
space and then combine the images later?

i dunno much about optics or imaging but it seems to me you
would need to make some image collage with millions of
images put together that were taken with a bigass lens
zoomed in on space.

seems better to me to just spawn a miniature clone of the
entire universe inside the lhc that we can just use a
microscope to examine amirite

store light by reflecting a portion of sky off a mirror and
bounce it off another mirror a thousand light years away so
in a thousand light years time someone can receive the image
and study it.

I guess lens is not the last invention in optics.

"Theories such as string theory and M-theory predict that
physical space in general has in fact 10 and 11 dimensions,
respectively" wiki

If you want "clone" universe I guess you need gather
information about it.

Visible light can be easily absorbed, so it is unpractical
to send imiges in that way and it is not the only reason,
that freqys "invension" did not work, or maybe I dont
understand it.

first of all, regarding the original post, the light still
has to hit a sensor and be interpreted as to the different
wavelengths, so it can be viewed in the (this case,) visible
spectrum.

wat you want to do, is preserve that light so that it can be
used in the future (when greater-technology sensors) have
been created, have a way to use the light from an earlier
time period, to hit an advanced sensor (now in the future),
and use the new data to study light from the past.

do you fully understand properties of light? of matter? of
how common day sensors work?

what happens if you use the mirror idea, and on the return
trip in 1000years, the light passes through a gaseous cloud,
or even worse, is terminated into a celestrial body that is
passing through the line-of-sight? ...oops

Basicly, yes, but not fully, nobody does.

...I meen visible light can be easily absorbed by clouds and
other things in space. Now SETI program using invisible
electromagnetic waves which is near hydrogen frequency which
is 1420 MHz. Those waves can escape clouds and it is harder
to interfere in space.

what a weak reply ..however you understand what im talking

what if you drive to the super market and get hit by a
truck? oops? so what ?? take a risk.

even if the light does get blocked by a planet for 2

freqy i actually can't tell what you're trying to say, but
it seems like english isn't your first language. i know
that they have sent an image in a single photon which was
posted here a long time ago. but that worked because they
were specifically sending it through a small 'stencil' so
that the photon captured the 'shadow' as its probability
wave passed through the stencil and then was 'lensed'
somehow to retreive the image. that was my understanding of
it.

but that's not going to get you an image of a galaxy since
those are made up of a number of photons and their relative
position & wavelength making up the image. so if you
'store' the light you're going to lose the image.

i know that for deep space telescopes they may be collecting
light one photon at a time depending on the source, exposing
it for days at a time, so that is a problem of the objects
being incredibly dim. i thought for a while that galaxies
were mostly invisible to the naked eye because they are so
far away they are too small to be seen, but that's not true.
the andromeda galaxy actually takes up something like 2x
the amount of sky that the moon does, but you can't see it
under normal conditions because it's just too dim.

freqy,

i will assume english is not your first language, but you
should really attend a high school level physics course; not
to sound condescending... i really don't understand if you
are being serious.

"what if you drive to the super market and get hit by a
truck? oops? so what ?? take a risk.

even if the light does get blocked by a planet for 2
hrs...SO WHAT?? wait ..patience it can be a stream of
information. "


what the fuck does that even mean.
light getting blocked by a planet for 2 hours? are you
meaning to say that all light waveforms can pass through a
celestial body?

holy fuck.

Must be freq meen that planet changes its position in orbit
and then waves can travel further, becouse you send your
information permanently. But this is not big problem,
comparing to difraction.

what he means is that the light would wait behind one side
of the planet until it has moved out of the way (this would
take exactly 2 hours) and the carry on its journey into

interpreting the way light acts in the physical world is

his education level. i'm guessing not much past 14 years/7th

and good lord, what does the lhc have to do with storing
light particles? that's like saying, "let's take a
photograph, but instead of a camera, let's use my race car!"
it may be a powerful piece of technology, but it can only be
used for what it's designed for.

o.k your not a foool just on another level which is neither
higher or lower.

when you walk outside the light reflected off your body goes
out into space ...it travels fast and far until it hits
something. or it may carry on forever. so light is stored
traveling in space. ...

so maybe one day we will be able to take samples of light
store the light in space and access the actual light
information rather than pixels.

no, the light does not go infinitely off into space once it
has reflected off me. i think the thing you're missing here
is that space is not just some empty vaccuum. space is
filled with particles, many of which will be getting in the
way of light including *gasp* the ozone layer! do you think
if we were receiving the full energy of the sun, even from
our distance, that life would have ever been able to evolve
on earth? hell no, and if the ozone is blocking light coming
in, what makes you think it won't have any effect on light
coming out.

the problem is that while, yes, much of the light may
survive to some far reaches into space, not nearly enough of
it is. especially the further out you go, the most distorted
and incomplete of an image you're going to be getting (if
any at all, assuming we have somehow sent out this receiving
station eons before the light we are trying to trap gets
there), with things like nebulae, space dust, celestial
bodies, not even to mention gravity (yes, there is gravity
in space).

and this talk about light being "stored" is utter bullshit.
you cannot bottle up light. it either goes in a direction or
is absorbed and converted into other energy. there's no
sending a few light particles into some continuous feedback
loop out in space (NOT a vaccuum!) to just reach out and
pick it up when we feel like.

my head hurts.
