Discussion Overview

The discussion revolves around the behavior of light, specifically photons, in the context of black holes and the perception of light from stars that may no longer exist. Participants explore the implications of light traveling through space and the effects of black holes on light's ability to reach an observer.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant notes that light from dead stars can still be seen on Earth, raising the question of whether an observer at the location of the dead star would see the same light moving away from them.
  • Another participant argues that an observer at the star's location would not see the light if it is traveling away, as the photons would not reach their detector.
  • A comparison is made to a ball flying away, suggesting that light, like the ball, needs to interact with a detector to be observed.
  • A hypothetical scenario is presented where a dying star collapses into a black hole, questioning whether a photon that never escaped could be seen by an observer at the center of the black hole's former location.
  • The same participant wonders if the photon could "catch up" to the observer's eye within the black hole, given that it started off at a distance, assuming the observer is not crushed into a singularity.

Areas of Agreement / Disagreement

Participants express differing views on whether an observer at the location of a dead star could see the light traveling away from them, with no consensus reached on the implications of black holes on photon detection.

Contextual Notes

The discussion includes assumptions about the nature of light, the conditions of black holes, and the mechanics of observation that remain unresolved.

I understand that a great number of star's we see are no longer there (now dead)we are just seeing the light traving from them over the vast distense of space, Question
If I were looking into the sky at night and seeing start light from a now Dead star and someone else (you) at the same time, was in the place that was once occupied by that star would they (you) be able to see the same star light moving away from them as I'm seeing on eath . IE would they be able to see the back of the light ??

Star->->->-Light->->->->-Me
You->->->-Light->->->->-Me
Just a question For a friday

Think about light as individual photons for a second. The only way you see light is when photons hit your detector, be that a telescope, the back of your eye, or some other device you've concocted. So ask yourself: How could the observer on the star possibly see the light if the photons were traveling away from him? He wouldn't, because they would never come in contact with his detector.
 
If a ball flies away from you, can it hit you in the head? It needs to bounce of something to come back. Same with light. But if you are on the our Sun, and you manage to shut it down instantly, you would see Earth for 16 more minutes.
 
suppose the dying star collapsed in on itself and made some sort of black hole, and the last photon never made it past the event horizon. If you were still standing at the center of where the star once was (now a black hole) would you be able to see the photon that never escaped and is now getting infinity stretched due the black hole ? or would you forever be beyond the range of the stretching photon and thus never detect it?
basically ... can the photon catch up to your eye within the black hole since it started a little ways off therefore giving you a "head start"?

assuming your not crushed into a singularity
