The real science of black holes

What would happen if you fell into a black hole? #astrophysics #einstein #generalrelativity

Okay, that's way scarier than just entering.

explanation: the light is being pullled back towards the black hole more and more as it gets closer so it take longer for it to escape that. essentially its lighr gets spread out over time. say the observer usually recieved 1000 light particles a second (obviously its way more) youll recieve less and less as the gravity pulls back harder until you get to the event hirison where the gravity is so strong 0 light paeticles are escaping per second. at that point the object will dissappear once that previous light gets to you. technically the object would never appear frozen, just so slow it would be indistinguishable from frozen. The object would be long gone by the time that light escapes the effect of gravity from the black hole.

If I were in the rocket ship, I'd shake my fist faster just to mess with my nemesis.

This is called an infinite red-shift:

The light emitted from the falling object has to fight the gravity of the black hole, and as it gets closer to the singularity, the escape velocity gets higher and higher. The reason a black hole is "black" is because the event horizon is the point in which the escape velocity is exactly the SoL.

So when an object reaches the horizon, light has to expend ALL it's energy to make it to your eyes, and therefore looses it all, stretching more and more until it looses all energy and "fades out"

...now what the falling object would see is MUCH different and terrifyingly awesome

The black hole is doing what time feels like in English class

If you shoot your nemesis at a black hole, they gets to watch you die.

"Shaking his fist at a constant rate" oh how mindful of him to shake it at a specific rate

vsauce wouldn't have left us hanging without an answer like that

My eyes: okay intresing
My brain: ZAWARDUO

When your nemesis is actually a metronome

The explanation to this phenomenon is as you keep getting closer to the black hole, light will have a hard time reflecting back as it will get overpowered by increasing gravity. So, the reflection takes more time to reach your eye as the spaceship approaches the black hole and at event horizon, there won't even be a reflection anymore.

This is actually awesome that time manipulation is actually real and there's so much more about the universe

The reason this happens is because there is a distance from the singularity of the black hole where the escape velocity is the speed of light. If this distance was, let’s say, ten meters, then anything closer than ten meters would not be seen from an outside viewer. Instead, the light from when they were still farther from ten meters from the singularity is all that’s left of what you could see, as the escape velocity in this region is SLOWER than light, but this would still slows down the light tremendously because the light still has a hard time escaping. Over time, the amount of light in that area decreases, so the object gets dimmer and dimmer until it just fades away completely. But the sheer amount of light that gets reflected means that if you could see lower wavelengths, you COULD still possibly see them, and see the little bit of light that was left.

[m-w-y]

of course another big thing people completely skip about black holes is that massive amount of energy, light and star dust etc is already circling around them and getting jettisoned outward as well, if you can pass this massive spinning force without getting vaporized by everything else around, well you will end up becoming into star dust regardless.

there is very little chance anything can even approach blackholes and survive long enough to even show redshift happening,

Props to the guy who tried this first 💀

The book Deaths End from the RoEP series has a part in it that covers a similar scene. A scientist falls in love with a miniature black hole he created and falls into it on purpose. To him he died in an instant. For everyone else though, they can still witness him falling into the black hole even years after the incident initially occurred.

This is pretty freaking awesome. The full video is great

[idacookies]

Something about "shaking his fist at a constant rate" is just so damn funny
