By the numbers

At approximately 10^11 years after the Big Bang, the Sun will swell to engulf Mercury, Venus, and possibly Earth, ending life on Earth.

“If you just go up to here, 10^ the 11 years, what happens here is the sun will get bigger and bigger. It swells. It eats up the close planets, Mercury and Venus. It may swallow up the Earth, too.”
