Here's what's crazy... His answer is right but his derivation is wrong... He used newton's laws to talk about an Einstein concept. Newton's laws don't work nearb blackholes because they make incorrect assumptions about what time and space are and a black hole just makes that obvious. There is no escape velocity at a blackhole's event horizon not because of velocity but because the event horizon breaks causality.

There's this concept in orbital mechanics called a "hyperbolic trajectory", which happens when your energy is too high to stay in an orbit. Basically if you start off far from a celestial object, you can get extremely close, and as long as nothing slows you down and you don't collide with the object, you'll still have way too much energy to stick around and leave. This doesn't work for a black hole within a certain distance, however, because iirc, if you get close enough, the warped space will adjust your trajectory so you get closer to the center regardless

Really interesting and well produced video. I was a bit surprised when the term centrifugal force was used. My understanding is the its the bodies inertia and velocity that keeps it in orbit, balanced by the centripetal force exerted from the orbited body. No centrifugal force involved.
@bdemaree3 жыл бұрын
It sounded odd because in physics centrifugal force is... well, it isn't. It's more of a layman's term to simplify centripetal acceleration. As you move in a circle at a constant rotational velocity the force vectors add up to equal a positive acceleration directly toward the center of the circle. (Or something like that, my last physics class was like 10yrs ago). As you accelerate in any direction your inertia resists the movement, think sinking into your car seat as you gun it, giving the FALSE impression that there is a force pushing you back. The only REAL force is the seat pushing forward. When you add gravity it gets weird because while gravity is calculable it breaks basic physics. ALL forces in physics are positive. They all push. On the maths side it's easy to add a negative sign to balance the equation, but in physics there's no such thing as pulling.

You could have used the ball example instead to illustrate clearly the illusory force of gravity, i. e. actually the constant falling of mass towards other gravicenters like in earth. This would also have helped prepare for the usually not circular effect on a given object; both while orbiting and in it's form, like the ovoid earth.

That being said, and just as a conceptual, it is possible that a strong enough magnetic alloy forged from a star could be set around the event horizon.

The technology needed is absurd, but if humans make it to heat exhaustion, it'll be one of the few sources left for energy.

@Taime882 жыл бұрын
@@HugoFilho. I'm not sure if this is an add on or a counterpoint. That said while yes it does have negligible mass by comparison, it does influence many large bodies in the galaxy. It can't be taken for granted it sits at the center of a rotating mass (galaxy). That said the instability range is a bit to close for where you'd want any part of a Dyson sphere like construct to be in place. Though in theory the chaotic nature of the event horizon could be manipulated for the formation of stars. But that's a seriously diffacult concept without first knowing we can make an alloy strong enough to not be spaghetified too close to the event horizon. The concept however would be to use an inner sphere as something of a pressure plunger. Creating a strong enough pressure zone inside may trigger an explosion not unlike a quasar, but again we'd first need to figure out a regular Dyson sphere for a star (Dyson sphere may be the wrong vocabulary term, however if you know to correct it you know what I mean, I'll take the points off for that, my recent study is cognitive function and behavior of chemical abuse, and rehabilitation techniques.) In theory it could be used to cause an explosion that could provide raw materials for star formation, but it's a seriously questionable theory. I did note in OP this was only a possibility worth researching, and that suggesting we make it to heat exhaustion, black holes simply would be our only bet for continued survival, and so the concepts of how to do that are worth exploring, even if we'd be looking millions of years ahead of time.

Math and science are not my things. I'm proud to say I actually followed this video! Awesome 👌🏾👏🏾👍🏾 This actually made sense to me.

the way of explaining gravity with hands was gold.

That explanation of how the balls move closer together as they fall down explains a lot about how small matter might congregate into planetary bodies. Very interesting!

6:00 Yes! Yes indeed. I realised this some time ago, but it is hardly ever mentioned in videos. You can’t see the bend between you and the event horizon…but your radius from the Black Hole gets greater as it expands the radial length into the extra/4th/Time dimension. It shows up though as time dilation. So…since the distance gets ever longer as you approach, it takes ever longer to get there. We observe time slowing…but to traveller, time is passing normally….except, and they can’t detect this, time is no longer orthogonal to time at a distance…as you would observe on a space time diagram.

0:11 Black holes are probably the one thing you can technically wrap your head around

I really like your analogy whereby the Universe is an uber' complex sym and the black hole's a bug- too much matter in too small an area. Codes break down. Love it!

Where do you get the music you use in the background? Its really good

Kinda clickbaity title - you CAN orbit a black hole so long as your orbit is well above the ISCO line.

That simulation of the guy falling into the black holes with the two balls gave me an existential crisis

Awesome presentation, along with the newest black hole video. I'd be surprised if this channel doesn't blow up big time. More space content?

Excellent explanations! In 180 seconds you covered the gist of gravitation, escape velocity, and conservation of energy. Very impressive
