A scary thought. Rogue waves have become better understood out in our seas. They sink ships. A mechanism that seems to emerge from the chaos of waves at various angles (not clearly understood by me but anyway). NB. Waves would become pinnacles popping in and out if the universe were bounded...

I suggest at least 4 spatial dimensions, but it depends on the context. Our universe has three spatial dimensions and time. Time is possible because our universe is 'embedded' within a 4-dimensional space. This is proven (?) by the interchangeable use of light years and years. Time, I...

The Earth Spins and it shows as an Equator Bulge. Yes there always will be a foundation reference; ultimately the 'cradle' for all things. But within a reference frame, it is possible to distinguish between spinning and not spinning. For example, space spinning around the planet Earth would...

Special relativity can be expressed by a circle with a vertical axis and a horizontal axis passing through the circle's origin. If the vertical shows time where the origin is zero and the horizontal is distance then the radius at any position describes all possible compromises for speed. The...

It seems that it is time moving through a quantum future that gives rise to the illusion of 'the speed of light'. The speed of light arises as a consequence of our time function. Equally, the waves thrusting through the quantum world result from our "Now" rolling forward to produce a past and a...

Might 'Space Compression' substitute for ' Space Shrinkage'? I mention this because Brian Cox (Black Holes by Brian Cox and Jeff Forshaw) talks about space flowing into black holes. If realistic we can imagine space flowing into mass (causing gravity). She changed her mind about a trip to...

Interesting. You might be interested in an idea relating to the application of Special Relativity as applied to our whole universe. Oh, just been told I have to take her and the dog to the coast today. Will have to wait - a new thread maybe

How does this explanation for the glitch go down? Re Billsluggs "Balloon Analogy" (in reality a hypersphere) The distance to 'Time Zero' is significantly further than in a Flat Universe Scenario (which seems to be the first call assumption). Gravity weakens with distance, yes? The effect is...

Sure, that's what a hypersphere is: Analogy: blow up the balloon surface is 3d space etc. I referred to your post some time ago requiring discipline regarding the word "universe". I could not remember what was said. But back to the theme. The universe (balloon universe(?) I described as...

Time Zero - Big Bang to Date - is approx 13.8 billion years. Time Zero measured spatially from now to then is 23.25 billion light-years (If we are a hypersphere) The Hubble Constant relationship is the universe's expansion derived from the age (13.8) and the circumference increase. An AI...

Time points inward in a black hole (our time that is). Are there such things as negative photons? If there were maybe a black hole is also a white hole with a reverse time direction (?). Quantum fluctuations aside...

Hi again Bill, sorry billslugg, That leads to a further thought. I remember reading one of Hawkin's books talking about our event horizon. I had not really connected that with the observable universe; our observable universe. I guess he must have meant the event horizon which, from any chosen...

Yes gravity-bound systems do not expand spatially. Quite how to attribute additional space added within galactic clusters is unknown to me - if space is added at all

To be sure we had it right I also asked Gemini: " An observer who has already fallen inside the event horizon of a black hole would indeed be able to see light from outside, for a brief period. Here's why: Event Horizon is one-way for escape, not entry: The event horizon only prevents...

Hi billslug ! I was not convinced so I asked "Copilot" The reply was as follows: "So, if you were falling into a black hole, you would indeed be moving toward the singularity (the central point of infinite density), but your velocity would not reach or exceed the speed of light. The event...
