someone please explain this too me?

Yes.

Technically, to an outside observer, it would seem like it takes you an infinite time to enter the black hole.
And by enter I mean get torn apart at the atomic level due to gravitational differences.

To a distant observer, clocks near a black hole appear to tick more slowly than those further away from the black hole.[45] Due to this effect, known as gravitational time dilation, an object falling into a black hole appears to slow down as it approaches the event horizon, taking an infinite time to reach it.[46] At the same time, all processes on this object slow down causing emitted light to appear redder and dimmer, an effect known as gravitational redshift.[47] Eventually, at a point just before it reaches the event horizon, the falling object becomes so dim that it can no longer be seen.

On the other hand, an observer falling into a black hole does not notice any of these effects as he crosses the event horizon. According to his own clock, he crosses the event horizon after a finite time, although he is unable to determine exactly when he crosses it, as it is impossible to determine the location of the event horizon from local observations.[48]

i thought that from YOUR perspective you wouldn't enter due to time slowing for you and only you
an outside observer would feel no time difference and see you go under the whole "spaghettification" process for a lack of a better term.
>"spaghettification" would refer to you being torn into a big stream of atoms like a strand of pasta :D

>>4072580

No, you actually cease to exist as you enter a black hole.

>>4072591
For a supermassive black hole, the gravitational gradient can be gentle enough that spaghettification only happens when you're already way below the event horizon.

>>4072598
No, it's like he described.

>>4072580
>do you actually enter the black hole from YOUR own perspective?

Oh course. How the fuck could you observe your own time going slower then your own time? Think about shit before you post!

>>4072608
alright thanks for the answers guys

No because the closer you get to a black hole the faster you are moving towards it.
You die from the pull before you manage to experiance the new perspective.
>So if deep gravitational fields are stretched the closer you get to time, time is slower if black hole?

aside from being pulled apart by the gravity etc. it would take an infinite time to reach the event horizon

Not that poster.

> And by enter I mean get torn apart at the atomic level due to gravitational differences.

Would it hurt, if that happened?

>>4072598
>from YOUR perspective you wouldn't enter due to time slowing for you

THAT MAKES NO FUCKING SENSE WHATSOFUCKING EVER. How can your measure of time slow down with respect TO YOUR MEASURE OF TIME? LMFAO

You will always experence the same measure if time when looking AT YOURSELF.

>>4072618
4chan is for those 18+, you are to young to be here.

>>4072598

Just needs to be said, but time can never slow for you from your own perspective.

You will always feel like you're going one second per second.

>>4072616
yes but gradually accellerating towards a super high speed that would normally kill you, would that still kill you in space?
no atmosphere to apply any outside forces to damage you, and the acceleration is gradual so why should that kill you?
i mean if you were moving at super high speeds in space
this is of course assuming your blood doesn't boil due to no pressure keeping it in liquid form in space (isn't chemistry fun too?)
and the lack of oxygen and warmth

>>4072601
No, for most intents and purposes, all your information would cease to exist except your spin and mass.

The rest of the information will slowly bleed out as the black hole dissipates. At least hypothetically.

>>4072622
OP thinks that he can use his clock, to measure that his clock is slow...

Yeah, Op must be like 12. But at least he is interested in science. Good job Op, keep up the good work!

>>4072622
ok that makes complete sense sorry for the dumb question lmao

>thread over this discussion has been killed
and thank you to the previous /sci/ answers that were also correct

>>4072634
haha you guys are going to make fun of me for this but I'm actually 19 studying biomed engineering. I now realize just how dumb my question was and I had the concept backwards
thanks for the answers though guys

and I'm a little more than interested in math and science I'm a freshman in Cal III and already done with University Physics 1 and 2. (through mechanics and electricity magnetism optics)
>again thanks for the helpful replies
Knowlege kills ignorance and I was being a little ignorant in my original question

Following a radial trajectory into a non-rotating black hole, you see that a massive object follows a path that takes it to the singularity in a finite amount of proper as well as coordinate time.

>Knowlege kills ignorance and I was being a little ignorant in my original question

OP realizes initial ignorace.
OP learns something.
OP seems like a bright guy, with a good future!

>19 studying biomed engineering

Besides the slight homosexual connotations, I don't think anyone is gonna make fun of you for not knowing all physics concpets.

The important part is that you are trying to educate yourself and are willing and eager to learn. I don't see how anyone of /sci/ could make fun of you for that.

i didn't mean precocious, fuck.

You could have deleted the post.
