how massive the largest known black hole in the universe is, via the standardized Toyota Corolla scale.

That number above is apparently equivalent to 40 billion sun’s. Feel free to double check the math. 40 billion sun’s worth of matter, built up over billions of years... With an impossible-to-know number of stars, planets, and other black holes swallowed in that period of time. If you can wrap your head around that figure, you’re lying. The black hole has a radius of 800 AU (the distance between Earth and the Sun) and is larger than many galaxies. With a near-incomprehensible scale, it’s approaching the scope of the modern day Dodge Challenger for the title of most massive known object in the universe.

The universe is so interesting.
