You got the ratio correct but the numbers wrong. t1 = 1.5 and t2 = .5
Use the transformation equations:
With these equations and the following rules you'll see that my system is free of contradictions.
Let's start with the basics. A frame is an absolute frame of reference if it is physically distinguished from all other frames and if it is totally independent of the distribution of matter/energy in the universe.
The simplest and easiest to conceive universe that has an absolute frame of...
The colloquium started without me. I don't even know the academician who delivered the talk. The posted sketch seems eminently believable, based on the elementary global theorem of the second link. If you believe the analysis is false, how then do you resolve the paradox of the great illumination?
The Special Theory of Relativity, we teach our students, did away with Absolute Space and Absolute Time, leaving us with no absolute motion or rest, and also no absolute time order. General Relativity is viewed as extending the "relativity of motion" applicable to curved spacetimes, and General...
Mathematicians prove negatives all the time
Length contraction is pretty standard stuff in special relativity. My perspective is that of a mathematician, not a physicist. My interest is only in mathematical possibilities, not the way the universe really is. This is the correct forum to discuss...
shrinking uniformly in time
My key words were “shrinking uniformly in time” and “Can you prove that homogeneity and isotropy alone disallows this possibility?”
My question is about geometry and the implications of homogeneity and isotropy.
I’m wondering if it’s mathematically permissible, if space is homogeneous and isotropic, for a moving rod to experience a uniform expansion or contraction during the time it’s not in its stationary frame of reference. What’s preventing a moving rod from returning to its point of origin smaller...
Joao Magueijo asserts in his book, "Faster Than the Speed of Light: The Story of a Scientific Speculation," _Perseus Publishing_, 2003, that revisions to special relativity are possible that do not contradict the relativity of motion.
Judging from the pages I’ve read I don’t believe Magueijo’s...
I appreciate you calling my riddle “the paradox of the great illumination.” If there’s a chance that I can figure out what you’re attempting to say mathematically, why not just explain in simple language what happens when my gedanken experiment is performed. How complicated must the...
I’m a spiritual man. The spiritual man makes judgments about all things, but he himself is not subject to any man’s judgment. 1 Corinthians 2:15.
You are right. So let’s move on and debate Einstein’s second greatest blunder.
Perhaps in the future you’ll believe in God.
I thought alis had explained that to you.
What do you mean by the asterisk? What is a flat reference frame? Which inertial frame in SxR might have an observer that wouldn’t agree to the space-time decomposition SxR?
You all know that Albert Einstein was deeply religious in his pantheistic veneration of the physics of nature. No scientist today should be surprised to learn that Einstein was completely wrong about true religion. This paper is about outrageously religious ideas in the philosophy of physics...
Let me suggest the physical meaning to the expression above.
I’m thinking of ds as an invariant that represents a differential increment of proper time. That would imply that the total amount of elapsed proper time t' would equal t/sqrt (1-1/V^2) where V^2 = (dx/dt)^2 + (dy/dt)^2 +...
Is it possible to invent a non-Riemannian geometry to justify the existence of a "metric" of the form:
1/ds^2 = 1/dt^2 – 1/(dx^2 + dy^2 + dz^2)
The only valid explanation of time dilation comes from understanding the Lorentz transformation equations. This is the first step. If you’d like to see a derivation of these basic equations, go to this link: http://www.everythingimportant.org/relativity
