A chemist, a physicist, and a biologist go to the beach. The physicist is intrigued by the waves, walks into the ocean to examine them and drowns.

The biologist is intrigued by the various forms of life, walks into the ocean to study them, and drowns.

The chemist is sitting on the beach with a lab notebook and writes “Biologists and physicists are soluble in water.”

“Most people associate my work being empty of people,” Höfer wrote. “And, indeed, this is what I prefer. I do not want to disturb people with my work, so I usually work before or after opening hours. I also found over time that spaces say more about people when people are not in them. But I am not dogmatic about that. As you can see…”

What is the Multiverse, and why do we think it exists? 

[…] Our observable Universe caps out at about 92 billion light-years in diameter, less than a thousand times as large in all directions as our previous scale. It contains some 10^80 atoms, clumped together in maybe a trillion galaxies, each with typically hundreds of billions of stars. But one of the most remarkable things about the Big Bang is that all of this, some 13.8 billion years ago, was once contained in a very small region of space, a region much smaller than our Solar System is today!

The thing that you might immediately wonder is whether there’s more Universe beyond the part that’s observable to us today, and — if so — how far does it go on? And what does it look like? And what are the physical laws in that part of the Universe?

Based on our observations of everything we’ve been able to see, from stars to galaxies to the leftover glow from the Big Bang to the matter in intergalactic space, we can learn some amazing things.
