There’s a rapidly expanding shell of photons 1-2 light years thick that perfectly capture the events on Earth during that time.
Some portion of those photons are heading directly towards a point in space where the will intersect one of the millions of black holes estimated to be in our galaxy.
Some portion of those photons will arrive along a trajectory just outside the event horizon, where their path is bent approximately 180 degrees.
Some portion of those will, at some point in the future, be intercepted by our planet earth...or hopefully an array of telescopes trained and synchronized in such a way as to allow us to reassemble a coherent view of a past earth.
- maxerickson 6y agoThe view through the atmosphere is more hazy than it is perfect. I bet the statistics are pretty dire after 3000 years too.
- jcims 6y agoSuper dire. It’d be like trying to photograph yourself in the rear view mirror of a pickup truck parked on Pluto. On the other hand, in the case of Saggitarius A we have ~50,000 years to figure it out.
- Koshkin 6y agoWell, looks like we are unable to “reassemble a coherent view” of current events, even. (And, speaking of physics, the light will die out dissipated by clouds of gas an dust.)
- jcims 6y agoProbably but it’s still fun to think about.
