  If it was a piece of the Sun from near its surface, you would be adding about 60 trillion tonnes of hydrogen gas at a temperature of about 5800 C.
  
  I imagine that suddenly all the Earth’s oceans and icecaps would explode into steam and probably every living thing on Earth. Good job it’ll never happen!
