I carn't see why not - area's of space with a high density of matter would be highly curved and so 'resist' spacetime expansion. Space is defined by the distance between objects, its not an independent entity, so the relative space between two exploding stars is expanding, whereas the space...
every reply seems to have focused on the fact that the speed of light is the same and always propagates at c relative to all observers in spacetime
but can the expansion of the universe - the rate spacetime itself expands - have an effect on the speed of light? if we're asking why light...
If the mathematical models have no correspondence to physical reality then why are they used as a basis to descriptions of the physical world?
I can assure you this is not 'my own theory' - I wish it was! I'm simply making conclusions, albeit speculative, on the established theory of...
hmm, well I'm not sure if I could make it any simpler! If you do a google search for black holes/time dilation you'd find a better-worded explanation to what happens to measurements at black holes.
At the end it is all speculation, albeit theoretically based. What bothers me is when you follow...
Not sure if you have interpreted my post correctly; I'm looking at it from the perspective of an observer approaching the event horizon and an outside observer uneffected by the black-holes curvature.
In the general theory of relativity the geodesics of spacetime are defined by light rays; the path of a light ray defines the shortest possible path between two points. However, once we remove matter from spacetime there ceases to be a reference frame that separates physical points, so the...
Curious.
The ZPE does indeed maintain a constant entropy relative to the Universes expansion. (see work by Rueda and Haish) but whether this could be linked with the holographic principle is questionable.
If entropy can be measured by the area of spacetime and the ZPF has an energy...
Dirac's best known postulate is his antiparticle postulate; that every particle has an antiparticle with equal mass but opposite charge and spin. This has been proven.
We get a good picture of particles/antiparticles through Dirac's 'antimatter field' - whereby antiparticles are disruptions...
Apologies for the late reply to this post.
With regard to my second point, 'that the universe would not exist from the perspective of a black-hole': the reason for this is because of Lorentz contraction - as the escape velocity of the star matches the speed of light. To observers outside the...
Chris: thanks for the info on 'Colliding Plane Waves in General Relativty' (http://www-staff.lboro.ac.uk/~majbg/jbg/book/Chap19.pdf ) .
The author makes no hint of implicit unification but it seems clear to me that this is necessary if we follow the GR-EMR connection to its conclusion...
They unified using a 5th spatial dimension 'wrapped up' in space. Superstring theory seems to be regarded as a better version.
But as far as I know, there is no mention of graviational/electromagnetic radiation unification?
There is a way we can conduct an experiement to test this hypothesis:
observe gravitational waves (GR) passing through a variable electromagnetic field (emf/v).
(the idea being, the displacement in the field caused by GR leads to the emf/v emmiting electromagnetic waves. The GR energy is...
The reason for saying this is because we observe black-holes with distinct properties; charge, mass and spin. If a black hole is a 'universe of itself', implied if it is a region of closed spacetime, then how can these properties arise?
I've made two postulates about black-holes that may be...
The density required to create a black hole can be given by p = 3M/4piR^3
From Schwarzschild equation the radius of a black hole in relation to its mass is given by R = 2GM/c^2.
Substituting this into the previous equation, we obtain p = 3c^6/32piG^3M^2
Therefore - p is inversely...
I know a lot of black hole questions have been posted, but these ones probably haven't arose before. I'd be gratefull for any responses.
1. Is it possible to have a black-hole 'inside a black-hole'?
I ask this because there is mathematical evidence to suggest the Universe is a supermassive...
