Henri Bergson: Half-relativity – Michelson-Morley experiment (8) – Dislocation of simultaneity

|

What will happen when operators respectively placed at 0 and at A want to measure the speed of light by noting, on the clocks tuned together which are at these two points, the moment of departure, the moment of arrival, … Read More

Causal Loops in Time Travel

|

About the possibility of time traveling based on several specialized works, including those of Nicholas J. J. Smith (“Time Travel“), William Grey (”Troubles with Time Travel”), Ulrich Meyer (”Explaining causal loops”), Simon Keller and Michael Nelson (”Presentists should believe in … Read More

Henri Bergson: Half-relativity – Michelson-Morley experiment (7) – Clock simultaneity

|

How do you adjust two clocks located in different places to each other? By communication established between the two people responsible for the adjustment. However, there is no instantaneous communication; and, since all transmission takes time, we had to choose … Read More

Henri Bergson: Half-relativity – Michelson-Morley experiment (6) – Measuring time

|

More generally, let us still call S a system immobile in the ether, and S’ a double of this system, which first coincided with it and then detaches itself in a straight line with the speed v. While S’ contracts … Read More

Henri Bergson: Half-relativity – Michelson-Morley experiment (5) – The speed of light

|

But we should also know why we ourselves, in our turn, measuring the speed of light by terrestrial experiments such as those of Fizeau or Foucault, we always find the same number c, whatever the speed of the Earth relative … Read More

Henri Bergson: Half-relativity – Michelson-Morley experiment (3)

|

Here then is the explanation proposed by Lorentz, an explanation of which another physicist, Fitzgerald, also had the idea. The line OA would contract by the effect of its movement, so as to reestablish equality between the two double paths. … Read More

Henri Bergson: Half-relativity – Michelson-Morley experiment (2)

|

Let us calculate, in fact, according to the usual kinematics, the duration of each of the double paths. In view of simplifying the exposition, we will admit that the direction SA of the luminous ray has been chosen so as … Read More

Henri Bergson: Half-relativity – Michelson-Morley experiment (1)

|

The theory of relativity, even “restricted”, is not precisely based on the Michelson-Morley experiment, since it expresses, in a general way, the need to preserve the laws of electromagnetism in an invariable form when passing from one system of reference … Read More

The singularities as ontological limits of the general relativity

|

The singularities from the general relativity resulting by solving Einstein’s equations were and still are the subject of many scientific debates: Are there singularities in spacetime, or not? Big Bang was an initial singularity? If singularities exist, what is their … Read More

Anomalies of General Relativity

|

Over time, the general theory of relativity has accumulated several anomalies and discrepancies, indicating the need for a better theory about gravity or other approaches: Stars in galaxies have a distribution of increasing speeds from the center to the periphery, … Read More

Cosmological Tests of Gravity

|

The current cosmological models are built based on general relativity. The solutions of the specific equations, Friedmann-Lemaître-Robertson-Walker, [1] allow to model the evolution of the universe starting from the Big Bang.[2] Some of the parameters of the universe have been … Read More
