Black Hole, wat do?

[Anonymous No.3071332]

Let's say you were unfortunate enough to be in a spaceship slowly falling towards a Black Hole. Thankfully your shields are working, so the radiation has not fried your brains yes. But your engines are not. As Scotty/Geordi/Carter tries to fix the problem, You fall closer and closer to the event horizon. But your engines kick back on before you pass the point where the escape velocity exceeds your maximum speed (ignoring warp engines. Chewie just got the sub-light engines working for now).

Now here is my question, /sci/lons. How much relativistic time dilation would the ship & its crew experience? If they were trapped for a few hours from their time-frame, how much time has passed in the "normal" part of the universe?

[Anonymous No.3071346]

There's a whole lot of numbers you need to give us.

Mass of the black hole, distance from the event horizon, is it currently eating another sun, what is the relative observer and how far away are they, also the movement of the black hole relative to the movement of the observer watching the ship struggling to avoid falling into the event horizon.

[Anonymous No.3071351]

At the event horizon, there is infinite time dilation. It makes no sense to speak of relativistic effects after they have passed the event horizon, though.

[Anonymous No.3071368]

>>3071351
He didn't say they passed the event horizon, he asked for the dilation. He also left a lot of needed information out.

From your viewpoint, you instantly traveled from rest position near your home planet to a stable orbit above a slowly rotating black hole of exactly 5 solar masses at a distance of 100 kilometers from the event horizon. The distance from your home planet to the black hole is many hundreds of light years. You remained for three weeks(504 hours) of local time, and then instantly traveled back to your original position.

From the viewpoint of an observer on your home planet, how much time has passed?

[Anonymous No.3071404]

OP here... let's assume it's a Black Hole of roughly 10 solar masses. To keep the math simple let's say the ship's maximum velocity is 100km/s... and they can sling-shot around the black hole if need be. Not really sure what kind of numbers you folks NEED.

this is the kind of thing I'm asking, but I just want a general answer: a few weeks? A few years? Centuries?

[Anonymous No.3071421]

>>3071418
Look bro, I posted that because what you posted has too many undefined variables, and fuck, even what *I* posted was pretty vague.

The only correct answer is "not enough data given".

>You remained for three weeks(504 hours) of local time

Easy. How much time was experienced by the crew?

[Anonymous No.3071428]

>>3071422
that...what...?

What's what was meant by "local time".

You, the person doing the traveling, experienced 504 hours. Or if you prefer, "the crew" experienced 504 hours.

>and they can sling-shot around the black hole

That actually only works in movies.

>the ship's maximum velocity is 100km/s

They didn't get very close to the black hole. They gained a few seconds per hour.

[Anonymous No.3071437]

>>3071428
I'm guessing "local time" meant whoever was watching the ship avoid the black hole.

So what exactly is time dilation and how does it work?

You aren't using a name. Forgive me for thinking you were another anon because you are not OP.

Now that I... 100km from the event horizon for 3 weeks?!

Nice engines. I want a ship like that.

Working on it.

[Anonymous No.3071483]

>>3071475
Seriously? The whole instant travel thing didn't impress you more? I mean with that, theoretically it could go PAST the event horizon and return.

[Anonymous No.3071485]

>>3071434
hmm what about 1,000 or 10,000 km/s?

[Anonymous No.3071491]

>>3071483
The problem in question is the dilation. I can disregard the teleportation because it is not part of the problem.

[Anonymous No.3071496]

>>3071491
The reason for the teleportation was so you could disregard the travel time to and from the 100 km point from the horizon.

wat if you had like a totally super strong peice of rope and tied yourself to it and then jumped past the event horizon but then your friend pulled you back out

[Anonymous No.3071549]

Akin to asking why a perfectly rigid stick that is 1 light year long can not transmit data faster than the speed of light.
The answer is the same.
Because physics doesn't work that way.
