### Class subject: Power Comparison.

 According to Wikipedia in 2018, the most powerful thing in the Universe is the Planck power, the basic unit of power in the Planck units. This is a lot of zeroes after the Yottawatt. The most powerful thing on Earth is the Tsar Bomba hydrogen bomb, equal to 5.3 Yottawatts. And the least powerful known thning is the approximate power of gravitational radiation emitted by a 1000 kg satellite in geosynchronous orbit around the Earth, equal to some Yoctowatts.
