OK, I am trying to reason through your thorough reply with my limited understanding of relativity theory. So, let's see if I understand correctly: A photon traveling in a linear direction from Sirius to Earth traverses the entire distance in one moment relative to itself (measured in a unit of...

Is it because the speed of light is only achieved in vacuum, whereas light which travels through the universe is traveling through a medium and therefore light is not traveling at the speed of light? Just doesn't make sense to me that a mass-less particle (photon) which should not...

Am I understanding superposition correctly? Is it equivalent to "all-potential"? In the double-slit experiment, when a single particle is "fired", it will pass through the slits as a wave but hit the receiving end (screen) as a particle. Each particle will clump on the screen, but after many...

My current understanding, albeit extremely naive and novice, of quantum mechanics seems to disallow a materialistic worldview (though only philosophically at the moment). Here is a synopsis of a conversation with a friend, I'm blue: Materialists: Your thoughts of quantum physics? Well, it...

Let me know if there are any errors or holes in my logic, facts, or assumptions. I was thinking in regards to time being relative to the observer and the resulting impossibility of an objective measure of time: In determining the age of the universe, our current estimation is about 13.2...

Is SR-allowable time travel "future-only"? Relativity theory allows for the possibility of time travel to the future, according to time dilation as illustrating by the twin paradox. Wikipedia says, "it is currently unknown whether the laws of physics would allow backwards time travel." My...
