Something like the CTMU perhaps? -

Graduate Quantum Fluctuations and the Origin of the Cosmic Microwave Background Radiation
Well, how about pair production in the multiverse? That is to say, a 4D white hole and black hole pair form in a higher dimensional space. Because they are pair produced, they exist in perfect equilibrium at t=0. No quantum fluctuations. They would interact with their surroundings but the... -

Graduate Does spacelike separation have anything to do with non-locality?
The cause-effect relationship of timelike events is fairly self-evident. But I was wondering, do non-local effects of QM "synchronise" events that are separated along spacelike intervals? Could there be some kind of co-dependent arising, such that if event X happens in one region of the... -

Is there intelligent life out there? I have a strong argument that says no.
Hey, he said intelligent life :-p Your arguments are fair OP but I have contentions. Consider if there were life on a zillion different planets all springing up and evolving simultaneously with Earth. All of them looking for intelligent life and lacking the tools to easily discern its...- dst

Undergrad Kinematic equation looks like a Taylor series
This is correct. Of course, the higher order terms vanish very fast so we don't really need to consider them. And yes, it is a taylor expansion of sorts except a Taylor expansion involves summing from 0 => infinity. It follows because in order to get the position, you need x(t=0), then add on... -

Graduate Is there more to the universe than what we can see?
There is no way to falsify the existence of anything beyond the "observable universe" so for all intents and purposes there is no saying "certainly".- dst

High School How does a given wave acquire it's frequency ?
Through the relation e=hf. Given a certain amount of energy due to be released (say by an electron changing state) the resultant wave will simply have that frequency.- dst

Graduate A fast fly hits a train and then ?
I doubt much of the energy would be released. Most likely depends on the material properties. What kind of bonds would even hold tight at that scale?- dst

Help me restore to normal sleeping hours
You can either gradually shift your pattern or snap straight into the normal cycle by sacrificing a day. The latter needs a lot of committment; just stay awake for 2 days straight and fall asleep at exactly the time you want, using caffeine as necessary. You'll then have to somehow force...- dst

Is This Perpetual Motion Machine Really Possible?
Well at least the laws of statistics are broken, given that the cat always hits the ground instead of butter. I think we have an infinite improbability drive here, not a perpetual motion machine.- dst

High School Does it matter if I turn my computer off?
Completely incorrect, the whole point of the multitude of fans and heatsinks in a computer is to disperse as much heat generated by the components out of the case as possible.- dst
