      Very interesting question!!

      So time is not fixed like we know it on Earth, it actually changes depending on where you are in the universe. If we travel through space in a rocket then time still exists because we will get older.

      However, if you travel to something with loads of gravity (like a black hole) then time actually runs slower compared to Earth!
      So if you spent a year going round a black hole in a rocket, and then came back to Earth you might find that it’s actually been 10 years on Earth!
