Theoretically, yeah, but you'd have to wait 50 years after you put it there for the first light to return and, given that we haven't got telescopes even close to good enough to pick out planets from that sort of distance, it'd be fairly futile... you'd get a reflection of an awful lot of the milky way.. you'd be able to see the Sun as if it were a much more distant star.RandoRando wrote:i Always though that blackholes if you were able to survive one, are wormholes to go back in time ..i dont know how to explain this
like that philosophical thought, seeing as light takes a year to travel a light year. if we put a giant mirror 50 light years away (big enough to see from earth) would we see the relfection of the earth 50 years ago? (not counting the time it takes the light to reflect back)
That's not really a philisophical thought, it's more a physics one.
I'd suggest reading some Stephen Hawking if you want to try and get your head around blackholes... nobody really knows at this stage, but wormhole to the past is probably one of the least likely options. Wormhole to another universe or another point in time/space within ours still gets thrown around. Of course, it might well turn out that the singularity is a failure of our current thinking rather than a real phenomenon... a lot quietly expect an as-yet unconsidered rule will mean that "infinite" mass can never be achieved.
Either way, I doubt we'll ever be able to pass through one to find out. We're so terribly fragile, we definitely can't survive where photons can't.
