As time goes by,there are going to be big changes in our everyday life.For example,when we are hungry,we don't need to cook in a hurry.Just take some pills,and everything will be OK.When we are free,we can go anywhere by spacecraft.It will be very cheap,just like taking a taxi now.
And of course,if we want to see what is like under the sea,just travel down there in a flying object like UFO.Maybe there will be a lot of cities and people living there
