BigThnk: "Nothing" doesn't exist

“Nothing” doesn’t exist. Instead, there is “quantum foam”

When you combine the Uncertainty Principle with Einstein's famous equation, you get a mind-blowing result: Particles can come from nothing.

The concept of "nothing" has been debated for millennia, by both scientists and philosophers. Even if you took an empty container devoid of all matter and cooled it to absolute zero, there is still "something" in the container. That something is called quantum foam, and it represents particles blinking into and out of existence.

沒有「無」。Quantum foam 自有永有。
