"Google" is actually a spelling mistake.
The company named itself after the huge number googol - 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 (1 with 100 zeroes after it), but accidentally spelt it wrong. You can also say it's 1000 trillion trillion trillion trillion trillion trillion trillion trillion.
To give you an idea of how big that number is, an electron's mass is a googolth that of the Observable Universe's mass.
