Clayton Robinson asked the Naked Scientists:
   
I have a theory to share with you regarding space time, dark energy etc

I'm not a learned man so forgive me if this seems a really stupid idea.

I will use the analogy of a trampoline to explain my theory...Gravity is a mass on the trampoline stretching space time and anything that falls towards it can be caught by said mass.

I believe that the centre of the universe must be a focal point with most things orbiting/falling into it..therefore must be a huge mass at centre or a black hole, which would suggest a shrinking universe

Now back to my analogy of the trampoline(im thinking in 2d at the moment to ease my explanation)...if a huge mass was falling from the other side of the trampoline ie from underneath this could make space time as we see it expand, possibly anti-gravity

if said masses are so huge causing our universe to expand eventually then because of the difference in forces, the universe will fold over on itself to 'the big crunch' if you like.
could those masses be interpreted as dark matter/energy from our reality..94% unaccounted for mass on our side of the trampoline would mean huge masses on other side, which would lead to our side expanding faster and faster..or stars close to high concentrations of dark matter being pushed apart faster relative to normal expansion

Matter cannot be created nor destroyed(forgetting quantum laws for the moment)...black holes could be venting system for sides to reach equilibrium and also a gateway for when our universe does collapse it will create another big bang on other side of universe(still using trampoline analogy)

ooh could I please get a mention on your radio 5live show : )
Im a big fan of your radio show, keep up the good work

kind regards



   

   

What do you think?

You couldn't use that analogy to explain a uniform gravitational field. In any case analogies are used to help someone visualize/understand a theory. They can't be used to explain the theory itself.

I believe that the centre of the universe ..

The universe doesn't have a center to it.

could those masses be interpreted as dark matter/energy from our reality..94%

No. The only difference between dark matter and normal matter is that you can't see dark matter, i.e. it doesn't couple to electromagnetism. And dark energy is only evident on the cosmological scale and is not found yet working between stars or planets so it may not work like normal matter's gravitational field.

Matter cannot be created nor destroyed (forgetting quantum laws for the moment)

Sure it can. We don't forget quantum laws because they're inconvenient and you didn't forget it for only a moment but entirely.
