I thought gravity was a fundamental force in the space time continuum? Surely it doesn't "go" anywhere? Its more a force of mass isn't it?
Close enough  "
I do try to pay attention to the world around me... |

It isn’t a force it’s a consequence of the curvature of space time. |

Well it's a force caused by the curvature of space time. |

The force or energy comes from the mass. |

Ah good question. My understanding is that the universe is still expanding at a speed that counteracts the weaker force of gravity. |

It's all very complicated. The expansion is theorized to be driven by dark energy. But the only reason we know that the universe is expanding is because we can measure the red shift. It's not like we can see the edge of the universe afterall. |

In a way. I think the force we know gravity is caused by the mass of an object bending the space-time around it. Like if you placed a bowling ball onto a rubber sheet. The sheet would bend downwards under the weight of the bowling ball and a smaller object(say a marble for instance) would fall into the warped area of the sheet. That's gravity, or at least how Steven Hawking describes it in a brief history of time anyway... |

But it cannot expand infinitely. That would be impossible. So what happens when it finishes expanding? |

"Does Gravity not actually do the opposite
ie it holds us down
also space has no gravity
"
Not true, gravity is everywhere. The force is proportional to the inverse of the distance squared so it can never be zero unless it's at certain sweet spots where it cancels out. |

Well we dont know, we would have to be outside of the universe to see. But considering the universe dictates the dimensions we will never really know. |

Ah yeh that's one of the older theories. That space-time will begin to cave in on itself eventually, dunno if the laws of thermodynamics allow for it though? |

Eventually yeah. New stars will eventually stop forming, then as stars die out we will be left with white dwarfs, neutron stars and black holes. Eventually the black holes will evaporate so the only thing left will be photons flying around. |

It isn’t a force it’s a consequence of the curvature of space time.
Yeh but then my understanding of it was that the mass of the matter in the universe causes space-time to curve though?
Something like that.
Yeh, the curvature of space time is a consequence of mass?
So what stops the universe collapsing?
Ah good question. My understanding is that the universe is still expanding at a speed that counteracts the weaker force of gravity.
That’s dark energy now I know you don’t know anything about that
My understanding is that no one really does do they? A lot of the stuff about dark energy is speculative?
Yea and dark matter and most things to do with the universe are speculative until proven
You cant catch me out!
Mate not trying to
Well at least give me time to have a quick read of wikipedia...
Haha is that what you lot are doing?"
I'm not, mines based on years of aggregated knowledge and a degree in physics |

I thought gravity was a fundamental force in the space time continuum? Surely it doesn't "go" anywhere? Its more a force of mass isn't it?
Close enough

Ah good question. My understanding is that the universe is still expanding at a speed that counteracts the weaker force of gravity.
It's all very complicated. The expansion is theorized to be driven by dark energy. But the only reason we know that the universe is expanding is because we can measure the red shift. It's not like we can see the edge of the universe afterall.
But it cannot expand infinitely. That would be impossible. So what happens when it finishes expanding?
The heat death of the universe, the end point of entropy. All matter comes to a standstill sort of thing.
A depressing end. I would like to think that it collapses in on itself, and a new universe is created. A cyclical event.
Have you heard of the bubble theory I think its called? That new universes are being constantly created in parallel dimension via energy expanding through wormholes. Fascinating stuff...
You making my brain hurt. If that’s the case, we will be having this same conversation in another dimension. "
If infinity is true then we’ve had this chat millions of times on millions of earths |

Not millions, infinite.
That’s why infinity doesn’t work in any model. |

Infinity is a useful mathematical tool, that's all that can be really said. |

If you like..... think of a number as big as you like even Graham’s number then add one does that work? |

This is true, the universe is peobably not infinite. Space-time curves inwards on itself. Theoretically it would be possible to fly a spaceship in a straight line and eventually come back to the point at which you started although the time and distance involved is pretty much beyond human comprehension... |
