I understand it is possible to observe reflections of large supernova level events. A possibility?

- lawless123 10y agoOur Galaxy is 100K light years across, the light would already have dissipated.
- planteen 10y agoI didn't know about this. Googled and found the Wikipedia about light echoes. Very neat. https://en.wikipedia.org/wiki/Light_echo https://en.wikipedia.org/wiki/Light_echo
- jcims 10y agoSeems like black holes could have this same effect on light from supernovas due to gravitational lensing. In fact, there should be some part of the area around a black hole in which the lensing effect bends light 180 degrees. With a big enough telescope we could observe our own solar system as it was thousands of years ago.
