Our space-time
Question :


If the sun disappears suddenly, which
 planet would fly out of orbit first?
I got it!
That is
Gravity
Where universal gravity comes from

       God
      create
         it
Does universal Gravity exist?
General Relativity
Space travel: dream of human
The distance between earth and Pluto
         is 44000000000km

  the velocity the fastest spaceship
               is 48k...
One way is to make the
     spaceship faster.
But the nearest fixed star is
   4.9 light year from us
The shortest distance between
    two points on a paper
The shortest distance between
    two points on a paper
Worm Hole
