😳Living Next to a BLACK HOLE! | Deep Space Dive

[00:00:00]Imagine a world where there are two suns in the sky, one a shining ordinary star and the other a black hole.

[00:00:08]Yes, >> [music] >> you heard that right. This planet is located in a binary system where a sun-like star and a stellar mass black hole [music] orbit each other together.

[00:00:18]From the surface, everything seems just like Earth, a warm glowing star in the sky.

[00:00:24]But when you look through advanced telescopes, you see something strange.

[00:00:28]Near the star is a dark object. This black hole is only 60 km wide, but its [music] mass is 10 times greater than the Sun. This star and black hole perform a unique orbital dance. The star weighs as much as our Sun and it revolves around a black hole that is 10 times more massive than it.

[00:00:48]Our Earth would orbit this [music] binary system very quickly in order to stay within the star's habitable zone. A year on this planet would last only 110 days. Although the black hole is 10 times heavier than the star, physically it is very small, only 60 km wide. So from the surface, everything [music] would still appear Earth-like. As shown in the film Interstellar, time slows down near a black hole, time dilation.

[00:01:15]Because of the black [music] hole's presence, clocks on this planet would run 4.7 seconds slower every year.

[00:01:22]That is negligible for daily life, [music] but we would have to factor it into our calendars and GPS systems.

[00:01:28]Now for the craziest part, tides. On Earth, the Sun's gravity contributes to our tides about half as much as the Moon does. But on this planet, [music] there would be not only the star's gravity, but also the black hole's gravity. So the tides would be about five times higher, even without a moon. Coastal cities would need protective systems to survive these extreme conditions. So why is this planet better than Earth?

[00:01:55]Because here we would have a black hole close enough to conduct experiments. We could directly measure Hawking radiation, throw something into a black hole [music] and observe it, or test extreme cases of time dilation, all from our cosmic backyard. [music] For physics, this would be invaluable.

[00:02:12]On Earth, the chances [music] of carrying out such experiments are almost zero. Recently, astronomers discovered for the first time a binary star [music] system orbiting near a supermassive black hole. This discovery proves [music] that stars can remain in stable orbits even near black holes. Who knows?

[00:02:30]Maybe a world like this truly exists somewhere in the universe. If you want more mind-blowing space facts like this, make sure to follow [music] the Facebook page right now.
