I only have some understanding of curvature and how objects behave while traversing curvature, my knowledge of what happens on the inside on, say a...
If no force is acting on a object it moves through time at constant velocity which is a straight line, if spacetime is curved though time appears to...
If you want the slowing of time to be cancelled everywhere in the sphere the plane of rotation would also need to rotate which would require an...
The outward expansion can be solved by rotating the sphere. If the sphere had enough integrity then the center mass wouldn't be needed. It would have...
I don't see how we could configure mass in such a way that time wouldn't be curved, or curved in a way that it wouldn't slow down. It's easier to...
You would be able to detect the time dilation by simply having a very accurate clock at that position and see how it has changed relative to a clock...
the gravity is still there, you just don't notice it, the net effect is cancelled but gravity is still there.
That would be correct, but forever young means stopping time completely which would require infinite mass. But you could make it go much slower,...
As long as there is mass it effects the curvature of space, however, mass could be configured in such a way that an object will not feel any gravity...
If you don't take into account the relativistic perspective then you run the risk of misinterpreting an coming to false conclusions, like there being...
Also, yes there would be a "wavefront" but as the universe during inflation stretched many times faster than the speed light it became very flat and...
Yes, energy and mass both create spacetime curvature by residing in it. Yes again that mass is a conversion of energy. The idea of gravity being a...
I should also mention that the curvature doesn't happen instantly but must as everything else move at most at the speed of light (hence creating...
It's not gravity as a entity of itself that reaches infinitly far, it's the bending of the curvature of spacetime that was caused by residing a body...
Why did it take five pages before you guys realised that nebel had misunderstood that there is no net gravity at the center of objects to think that...
The idea about studying animals is that we get a view that should have applied to humans in the past as well as now and also doesn't have cultural...
No one experience a now that is still and exactly "now", it is always running past us, even so, we can't imagine any short duration of time where we...
birch: In a multiverse, if that multiverse has every possible outcome, then there would be exact copies of you, one copy where you are exactly the...
Alucard89: Thanks! Could you elaborate on your previous post as to what you mean by causing another big bang? C C: Agreed. Do you mean the same way...
According to Wikipedia there's around 200-400 billion stars in the milky way, and the milky way is a pretty common galaxy. Each star can have several...
