Crossing the Event Horizon of a Supermassive Black Hole | How the Universe Works | Science Channel

Black holes are some of the most extreme and least understood places in the universe, where the rules of physics collapse and time warps. Here, we venture into the heart of a supermassive black hole in the center of the Milky Way to understand terrifying and fascinating secrets about parallel universes, wormholes, and space-time

Somehow I'm picturing Hotel California, once you cross the event horizon you can check out any time you like but you can never leave.

Everything that enters the “Event Horizon” will go where the missing socks 🧦 go in a washing machine

So what i got from this is that waterfalls are just earths version of a blackhole.

The scale was originally designed in 1964 by the Russian astrophysicist Nikolai Kardashev (who was looking for signs of extraterrestrial life within cosmic signals). It has 3 base classes, each with an energy disposal level: Type I (10¹⁶W), Type II (10²⁶W), and Type III (10³⁶W). Other astronomers have extended the scale to Type IV (10⁴⁶W) and Type V (the energy available to this kind of civilization would equal that of all energy available in not just our universe, but in all universes and in all time-lines). These additions consider both energy access as well as the amount of knowledge the civilizations have access to.

Oh wow! It's been a long time since I saw Dr. Moo in Because Science and Because Space. It would be nice to she her do a collaboration with Kyle again.

How can anything fall into a black hole. An observer will have to watch until the end if time to see someone get to the horizon, and the person falling will watch the observer live until the end of time by the time he gets to the horizon then his time stops at the horizon and the universe ends for both of them. Like interstellar movie 1hr is 7 earth years. Well ger cloer to black hole, now 1hr is 1000 earth years, get cloer 1 hr is 1, 000, 000 earth years, then 1 billion earth years and on and on until you get to the horizon and the universe ends. Its just like fast forwarding a movie. If you want to get to the end of the movie fast then fast forward it, the entire 2 hrs of movie still played, but now youre at the end of the movie and only 5 seconds older, not 2 hrs older. Black holes are no different. You fast forward into time near them, and the closer you get to the black hole, the slower your time gets and the faster you move through time.

The editing here was awesome but a bit repetitive, it's a literal vine boom lol

I love how they quoted that the universe is more stranger than sci-fi, really good stuff

[marktienter]

How much money did we pay that fool to tell us that everything that goes to a black hole disappears and doesn't come out and if it does we don't know where it's at

[swimfaniij]

I thought this was going to relate to the movie “Event Horizon.” Ooops

Since observers see you grinding to a halt as you approach the black hole - surely, just as when you travel towards the speed of light and back to zero speed, you would observe the observer moving through time at much faster (like in that film Buzz light year)

So as they see you coming to a halt - you are seeing them age faster and faster.... is that right?

Note: this is before you enter the back hole. I assume once you have entered - time outside effectively has become infinite, aka ceased to exist (whatever the heck that means!)

And it's just two miles across for a 2M black hole...

[Nefertiti]

How do we know it doesn’t open up somewhere else?

[alexsuited]

I loved these shows back in the day. How have the times changed, and some theory about blacksphere? There still awesome and enjoy them very much. Thanks. Peace ✌️ 😎.

[peachesb-georgia]

Wow 😳... just like some can survive a ride down Niagara Falls... I'm wondering if someone can survive a ride over the edge of a black hole... even if they do... will never be able to tell anyone... ugh 😫...

[alexandersaquapark]

Почему вы закрыли этот канал в Израиле???

[patricedhanis-rouse]

Wouldn't the pressure crush the probe.

[st.c.]

I hated the editing, with the fast cut-scenes that made you not be able to follow the idea presented & the constant omnious music in the background. It's like bad, amateur, slasher movie

[muhammad-bin-american]

All this because of a death of a single star?

[tomholroyd]

Is every SMBH a gateway to another galaxy?
