I would appreciate if someone could clarify this simple contradiction with the Big Bang.
Assume black holes exist, and are caused by the collapse of large quantities of mass due to gravity. The resultant singularity is so massive that not even light can escape, much less material.
Yet if the...
Greetings - I have a question about observables and Quantum Mechanics.
Let's say I want to measure the spin state of a particle.
If I measure σZ (sigma Z), I will get either +1 or -1. That will then prepare the spin state accordingly.
If I measure σX (sigma X), I will get either +1 or -1...
If gravity is effected by "wave particles", per Einstein's theory and now confirmed by recent observations, why do we not detect 'interference' - gravitational 'shadows' - or do we?
Consider that with light waves, a photon once it hits a detector, nothing behind the detector registers the...
I appreciate you all bearing with me as I admit my mathematical understanding of the underlying principles is lacking.
Much of my question stems from my current thought that space must be quantized - I don't see it being possible as being continuous - which is where my graph paper analogy...
So I read the balloon analogy "fix" in your sig - thanks for that, it does clear up some things.
However, I think the philosophical implications are still worth discussing - perhaps not here - and many obvious questions still remain unanswered, perhaps even become more difficult. For example...
I apologize if this has been asked before, but I have never seen a satisfactory or straightforward answer.
When we say the universe is expanding, do we mean it is "growing" or "stretching"?
In other words, if you considered a sheet of graph paper expanding, are we adding more squares or...
