If black holes don't exist then neither does the cosmic horizon?

AI Thread Summary
Stephen Hawking's argument suggests that non-penetrable event horizons do not exist, which implies that the cosmic event horizon may also be an "apparent" horizon rather than a definitive boundary. This perspective challenges the notion that we are isolated from the rest of the universe by a cosmic event horizon, as it suggests that information is not permanently lost when crossing this boundary. The discussion emphasizes that all information from the visible universe remains accessible, even as galaxies approach the cosmic event horizon. Participants express relief that galaxies crossing this horizon are not lost forever. The conversation highlights the importance of understanding information retention in the context of cosmic horizons.

So according to Stephen Hawking, non-penetrable event horizons don't really exist.

So by the same argument the cosmic event horizon can't exist either right? Only an "apparent" horizon which may hold information from outside the visible Universe for a short while until it enters the visible Universe.

The cosmic event horizon is often described as like living "inside" a black hole. But since black holes don't exist any more then this also means that we are not cut off from the rest of the Universe by a cosmic event horizon?

Have I got that right? What do you think?

I think the critical notion is that information is not lost when something crosses that horizon.
So anything that was ever within our visible universe has never been lost without a trace.

Well that's good then. It's good to know that all those galaxys crossing the Cosmic Event Horizon are not lost forever! :)
 
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...
