January 13, 2016 will be the one hundredth anniversary of Karl Schwarzschild's paper on the solution to the GR field equations around a spherically symmetric gravitating body.

You can find an English translation here: http://arxiv.org/pdf/physics/9905030v1.pdf

I urge everyone to read it. You will find there is no basis for a coordinate singularity (Black Hole Event Horizon) but only a physical singularity at the origin (null punkt).

It is time for a very serious discussion of this aberration of astrophysics (the Black Hole Event Horizon).

Actually, it wasn't just Schwarzschild who found this solution, I believe the Dutch mathematician Droste also found it around the same time. See e.g.

Edit Not sure about the rest of its content.

See http://arxiv.org/abs/1308.0394 (section III) for a discussion of what is wrong with Loinger's translators comment, and also with erroneous opinion of the OP. This is all very well trod math and physics. Repetition of misunderstandings does not improve them.

One thing the above paper doesn't do is compute the area of a surface of given 'funny radial coordinate' for a given t. If you do this, you find, for Schwarzschild's original radial coordinate, the limit of area as the coordinate goes to zero is NOT zero. This establishes that the radial coordinate=0 doe NOT discribe a point; it describes a sphere.

PAllen's post is all that needs to be said. Thread closed.
 
Thread 'Can this experiment break Lorentz symmetry?'
1. The Big Idea: According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box. 2. How It Works: The Two-Stage Process Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...
Does the speed of light change in a gravitational field depending on whether the direction of travel is parallel to the field, or perpendicular to the field? And is it the same in both directions at each orientation? This question could be answered experimentally to some degree of accuracy. Experiment design: Place two identical clocks A and B on the circumference of a wheel at opposite ends of the diameter of length L. The wheel is positioned upright, i.e., perpendicular to the ground...
In Philippe G. Ciarlet's book 'An introduction to differential geometry', He gives the integrability conditions of the differential equations like this: $$ \partial_{i} F_{lj}=L^p_{ij} F_{lp},\,\,\,F_{ij}(x_0)=F^0_{ij}. $$ The integrability conditions for the existence of a global solution ##F_{lj}## is: $$ R^i_{jkl}\equiv\partial_k L^i_{jl}-\partial_l L^i_{jk}+L^h_{jl} L^i_{hk}-L^h_{jk} L^i_{hl}=0 $$ Then from the equation: $$\nabla_b e_a= \Gamma^c_{ab} e_c$$ Using cartesian basis ## e_I...
