I see your point cesiumfrog. I was probably thinking too complicated. maybe this will help a bit. If something is changing with time or position and you know its value at one point you need something that helps you find it at the other if for example it changes exactly the same amount for...

The concepts do not have any basis in physical reality and so it is not possible to give any sort of explanation that is in any way accurate. Bodies are mostly made of water and it is possible to make water denser and even turn solid by compressing it at room temeperature but this requires...

Differential equations are a fundamental part of all science and engineering it is important to be able to understand them to do any serious science. The reason that scientists and engineers use them is that frequently it is more easy to relate differentials to things that can be measured...

The rings are rather close to Saturn and the differential gravitational fields are big enough to tear medium sized bodies held together only by their own gravity apart. this is sometimed called the Roche limit there are some very small bodies in the rings called shepherd moons that are...

A planet is a body that is big enough to have cleared all significantly sized objects in similar orbits out of its orbit around a star. Mercury to neptune have managed to do this. pluto is one of many smaller objects moving in their own orbits like the minor planets and is such a minor planet...

For the object to be captured by Mars in its current orbit its approach velocity and direction will have to be defined quite accurately or it will just shoot by. it will also disturb the orbit of Mars by quite a lot depending on the direction that it comes in. It is also quite possible that...

To talk of a singularity in a physical context is just a mathematicians cop out because the simple singularity only applies if you manage to create a black hole with zero angular momentum. This is so nearly impossible that it is really not worth considering in a physical context. It is far...

I agree Astronuc that globular clusters tend to be an exception to this rule. Open clusters are generally not stable relaxed structures and can be discounted. I have looked many times for a published theory of the origins of globular cluster structures and not found one. I have my own and...

That's really only part of the story chroot. I think it is important to explain why a rotating blob collapsing under gravity tends to become a disc. The anwer is as I believe that as various parts interact gravitationally or collide they tend to be disturbed and thrown into different...

Gravitational waves are nothing to do with radio waves which are electromagnetic the particle associated with these waves has been called the graviton The sort that people are trying to detect are in fact very long (or very low frequency) in the audio range or below brcause that's how fast...

Most normal (one solar mass or greater) black holes produce very little radiation indeed. Left to their own devices they are effectively considerably colder than the cosmic microwave background at a couple of degrees K and are therefore absorbing more radiation than they emit. Only very...

I have been interested in the phenomenon of "stochastic resonance" for many years and have always worked at the technonlogical limits of analogue and digital processing. Let me try to explain what is going on simply. Let us assume that you are trying to digitise an analogue signal with a...

Explosives work by using a chemical reaction that turns a solid into a gas very quickly. The gas occupies more than a thousand times more volume than the solid at normal temperatures and pressures and so a great deal of pressure and expansion is generated and this is the explosion. In general...

Note I tend to use the term our universe to mean everything that we can observe and strongly infer (like areas hidden by inflation) and the multiverse to mean everything there is. I personally favour a multiverse that obeys the perfect cosmological principle it that on a large enough scale it...

How then do YOU define the properites of an independent universe? Of course this is pure speculation the original question posed here was one that could only be answered with pure speculation because it dealt only with unobservables. Mathematical modelling is a perfectly acceptable...
