What Happens Just Outside a Black Hole's Event Horizon?

Click For Summary

Homework Help Overview

The discussion revolves around the characteristics and phenomena occurring just outside the event horizon of a black hole, specifically referencing a hypothetical black hole named Gargantua. Participants are evaluating a series of statements regarding the nature of gravitational effects, communication delays, and the behavior of physics in this extreme environment.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to assess the validity of several statements related to black hole physics, expressing uncertainty about their correctness. Some participants question the assumptions behind the statements, particularly regarding the nature of gravitational forces and the stability of orbits near the event horizon.

Discussion Status

The discussion is ongoing, with some participants providing reminders about the forum's guidelines on homework help. There is a clear indication that the original poster is struggling to articulate their reasoning and thoughts, which is necessary for further assistance. No consensus has been reached on the statements presented.

Contextual Notes

The original poster mentions a deadline for their homework, indicating a time constraint that may be affecting their ability to engage with the material effectively. There is a suggestion that they have consulted their textbook but remain confused.

Homework Statement


The following statements may or may not accurately describe what you would find just outside the event horizon of an extremely massive black hole like Gargantua (fake black hole), at a distance corresponding to an orbital circumference of 1.0001 times the horizon circumference. True or false for each.

1. Tidal forces cause the force on your head to be stronger than that on your feet, so you are violently squashed together.
2. Any messages you send to the outside world take essentially an infinite amount of time to get there.
3. You feel a gravitational force towards the event horizon.
4. When you look up at the night sky above you, you can see an infinite number of images of the outside universe spread all over your field of view.
5. All orbits are unstable, so instead of orbiting, you hover above the horizon.
6. The laws of physics do not hold.

Thanks

Welcome to PF.

We will not do your homework for you. You must tell us your thoughts, and explain to us how and why you're stuck. Only then will we provide any assistance.

I'm pretty sure #6 is true and 1, 4 are false but I've tried 45 times and can't seem to get the right answer. even looked in my textbook. please help it's due soon. Thanks!
 
Again, you need to tell us your thoughts, and why you're stuck, or we will not help you! We are not going to give you the answers; give it up.

If it's due soon and you have not planned your time properly, it's no one's fault but your own.
