Black hole/Hawking radiation thought experiment

AI Thread Summary
The discussion explores a thought experiment involving a spaceship crossing the event horizon of a black hole that is shrinking due to Hawking radiation. It considers whether the spaceship, equipped with unlimited fuel and capable of near-light-speed travel, could resist the black hole's gravitational pull and escape towards the singularity. However, it is concluded that once inside an evaporating black hole, all paths inevitably lead to the singularity, leaving no escape route. The conversation highlights the implications of Hawking radiation on black hole dynamics and the nature of spacetime within the event horizon. Ultimately, the thought experiment reinforces the idea that the laws of physics dictate a singularity's inescapability once crossed.

Hello everyone! New poster here.
I would first of all like to thank you all, since in these threads i have found answers to many of my questions about astrophysics!

I have a little thought experiment for you guys:

Lets say that because of Hawking radiation, the radius of a black hole's event horizon
is decreasing at the rate of X m/s
Lets imagine that such black hole is large enough to allow for a hypothetical spaceship
to cross the event without being spaghettified/destroyed
Lets also assume that such a spaceship has an abundant amount of fuel and can fire its
powerful engines for an unlimited amount of time, getting as close to traveling at C as
physically possible

If the ship were to cross the black hole, would it manage to resist the pull of the black hole
enough to travel towards the singularity at a rate of only (X-Y)m/s and therefore free itself from its pull? (recall that the black hole is receding at X m/S)?

Unfortunately, there is no escape route. Once inside an evaporating (spherically symmetric) black hole, all (timelike) paths lead to the singularity.
 
Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. 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.
