Why can't we use telescopy (across the EM spectrum) to view the formation and development of our planet? Let me explain by laying out some assumptions (correct them if they are inaccurate).
- When we use telescopes (again, I mean x-ray, radio, visual, etc) to capture photons from distant stellar objects, we are in a sense looking back in time. "seeing" a galaxy 10 billion LY away is seeing it as it was 10 billion years ago.
- The photons we collect with our telescopes vary in intensity based on distance and if they are emitted (from a star) or reflected (off a planet). Thus we cannot "see" planets that are too distant as the reflected EM radiation is weaker than that emitted by a stellar object.
- In this scenario we will assume all particles travel not to exceed lightspeed, but let us assume that we may discover other particles such as gravitons that will enhance our capabilities (so we might eventually see images of planets light years away).
- Universe is expanding.
Okay, is it possible, if we could calculate which direction to look, that we could point all of our telescopes (and hypothetical gravitic detectors) to look out 4 billion light years and see the actual formation of our solar system, which would be in a different location than now because of inflation?
And if so, could we look out 2 billion light years (time and distance) and see our nascent planet Earth, and then 1 billion LY and so on and watch our actual planet develop?
Again, assuming an improvement in technology, could this be accomplished, or is my logic flawed?
Thanx in advance.
