Discussion Overview

The discussion revolves around the fate of living things that enter a black hole, exploring theoretical implications, physical effects, and the nature of black holes themselves. It includes considerations of gravitational forces, the concept of event horizons, and the challenges of surviving such an encounter.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants propose that if black holes can trap light, they would similarly trap living things, raising questions about what happens to those beings once inside.
  • Others argue that the gravitational gradient near a black hole's event horizon could be lethal, potentially ripping apart macroscopic objects, including living beings.
  • A viewpoint suggests that supermassive black holes might allow for a gentler gradient, theoretically enabling a living being to explore what lies beyond the event horizon, although returning would pose significant challenges.
  • One participant challenges the interpretation of black holes and their event horizons, suggesting that common understandings may be misleading and context-dependent.
  • There is a call for clarification regarding the term "beyond a black hole," as it may imply different meanings, such as traveling past a black hole versus entering it.

Areas of Agreement / Disagreement

Participants express differing views on the nature of black holes and the implications for living beings entering them. There is no consensus on the fate of such beings or the validity of the interpretations presented.

Contextual Notes

Some claims rely on assumptions about the nature of black holes and the effects of their gravitational fields, which may not be universally accepted or supported by all participants. The discussion also highlights the ambiguity in terminology related to black holes.

Who May Find This Useful

Individuals interested in theoretical physics, astrophysics, and the conceptual challenges posed by black holes may find this discussion relevant.

Its said there up on the universe, black hole which even can trap the whole light entering through it, exists. But if anyone, I mean any living things, trapped there...I'm confused how can they go beyond the black hole...or will be they trapped, if so what happen their bodies?

If the black hole sucks light down, then it will suck down anything else too ... so why wouldn't living things get sucked down. Once sucked in, where else would they go?

The main trouble is surviving the journey - the gravitational gradient close to the event horizon can be steep enough to rip macroscopic objects like living being apart. However, supermassive black holes have a much gentler gradient so, in principle, a living being could go find out what is actually there where the Einstein equations have a singularity ... sort of.

Of course, the next problem is getting back home to tell anyone what they found.

Caution: I've been a bit glib. For details see...

... that should cover a lot of what you are thinking about.

Note: it is not clear what you mean by "beyond a black hole" ... I can travel "beyond" a black hole just by flying past it but I suspect that's not what you mean. Are you thinking of the black hole as a kind of passageway?
 
That is a pop version of the Schwarzschild metric where it is assumed an observationally finite universe has an event horizon. This is an extremely misleading and unsupported conclusion.

Which is? Context is everything.
You mean the "sucking" thing? Yes but it's not fatal. I have done this before.
Or do you mean something in post #1?

Yes, post 1. We posted almost at the same time.
 
Cool :)
Need to hear from OP now ... hello Sudip Prathan, any of this useful to you?
