Can we see the image of earth coming back to us after space travel

AI Thread Summary
The discussion explores the theoretical possibility of viewing images of Earth as they return after traveling through space, particularly near black holes. It highlights that such a phenomenon would require extremely precise conditions, making it highly unlikely. Current telescopes lack the resolution to detect Earth-sized objects more than a few light years away. Additionally, the photon flux from such distant sources would be minimal, resulting in a very low frame rate of incoming images. Overall, while intriguing, the practical challenges render this concept nearly impossible.

i am amazed by the possibility that if the light reflected from Earth comes back to us after traveling in space for thousands of years we will be able to see our past. And this could happen around black holes. Has anyone found an image resembling earth?

It would be highly unlikely, requiring a very precise set of conditions if it is possible at all. Besides-which, we don't have telescopes with enough resolution to view an earth-sized object more than a few light years away. Most of what we see of gravitational lensing takes place in/around distant galaxies.
 
Beyond the ridiculous conditions necessary and the resolving power, you also would have an incredibly low photon flux. So while you could receive photons, they would trickle in at a rate of something like a few per second. Hardly the 30fps movie I imagine you'd like to see.

Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
