✨Cosmologists believe most galaxies have a super-massive black hole at their centre, with a mass of between 1 million, or billions of times that of the Sun. All of a black hole’s matter is crushed into a tiny point of infinite gravity called a singularity. Science’s understanding of physics, space, and time breaks down beyond the black hole’s event horizon, the boundary of no return where not even light has the speed to escape its immense gravity✨

✨To a distant observer a clock near a black hole would appears to tick more slowly, this is gravitational time dilation. To the same observer, an object falling into a black hole would appear to slow down as it approached the event horizon, taking an infinite amount of time to reach it✨
