I am told that a beam of light gets bent by the gravitational pull of our planet.
If so, the same beam of light will get bent every time it passes close to a celestial object.
As the beam of light travels through our galaxy and out into the universe, I imagine that it must constantly get bent by millions of objects.
As the beam of light gets further from its origin and towards the edge of the universe, I imagine that it must get bent more towards the concentrated matter of the universe and might therefore end up travelling in a complete circle.
If so, anyone outside of the circle would not be able to see the light.
Hence our universe would be a black hole ?.
Can anyone progress this theory, or shoot it down in flames ?.
