Dale replied to the thread B Intuitive Explanation of Adiabatic Condition.Which part are you finding unintuitive? It is basically the conservation of energy, the ideal gas law, the definitions of specific... -
Dale reacted to Ibix's post in the thread B Gravity and speed of information for orbiting planets with
Like.
The EFEs reduce to the same form as Maxwell's equations in the weak field, so the behaviour in that approximation is obviously identical... -
Dale replied to the thread B A question about warp bubbles and navigation.Yes, e.g. post 7.

Dale reacted to weirdoguy's post in the thread B A question about warp bubbles and navigation with Like.
And it is perfectly clear from the context and how the thread went on.
-
Dale replied to the thread B Gravity and speed of information for orbiting planets.I know that for electromagnetism it is just the retarded position and velocity. I cannot remember for gravity if it is also the retarded...
-
Consider this: Instead of just that light clock, you have second standard Light clock next to it, with the mirrors spaced apart such...
-
Dale replied to the thread B A question about warp bubbles and navigation.Sometimes people don't understand how impactful that can be. I think it is clear from the context that you want to talk about the...
-
Dale replied to the thread I Question about a Square Light Clock.Yes, all clocks depend on speed in the same way.
-
I never said otherwise. I simply said that, in my native language, both the Alcubierre engine and the science-fictional warp drive from...

Dale reacted to Baluncore's post in the thread Not a sundial - a shadow dial is what I want with Like.
Tall deciduous trees like poplars, to your SE, South and SW, will allow the sunlight to pass during winter, but block the heat of the...
-
I don't remember. Over the years, I've read quite a lot of things about Alcubierre’s theories, and it's impossible for me to remember...
-
Dale replied to the thread B Gravity and speed of information for orbiting planets.Yes, and there is nothing that is non-causal in that extrapolation. It is all based on information at the retarded time.
-
Dale replied to the thread B Gravity and speed of information for orbiting planets.I am not sure how you can possibly think from what I said that there is anything not causal. The direction of the force is determined...

Dale replied to the thread B Gravity and speed of information for orbiting planets.Yes
-
Dale replied to the thread B Gravity and speed of information for orbiting planets.Yes, it is. No. It is the distance that the source would travel if it continued at the retarded velocity from the retarded time until...
