摘要：and now，the only reality we face is the darkness of the black hole。

The object you see right now is called GAIA BH2。

It's one of the closest known black holes to Earth。

It's located about 3800light-years away in the Centaurus constellation。

It's Schwarzschild radius is about 28.3 km (17.58 miles)。

We are crossing the event horizon。

the boundary beyond which not even light can escape。

Outer space is closing in around us。

We won't survive much longer。

the strength of gravity is increasing。

and now，the only reality we face is the darkness of the black hole。

Thanks for watching。
