Black Hole Singularities and Wormholes: Albert Einstein would have warned against them and Karl Schwarzschild would have corrected these ideas, caused by errors. This article explains extensively the history behind these errors and also how they must be repaired. It turns out that a so called Event horizon belongs in...

## Lorentz transformation or Minkowski formula?

loopdoctorFebruary 20February 200Level II Advanced

In his Theory of General Relativity, Einstein replaced the Lorentz transformation by the formula of his tutor Minkowski. What happens if we apply the Minkowski formula back into the Theory of Spécial Relativity? What are the differences? This article shows: the Minkowski’s formula doesn’t create the Twin- and Ehrenfest...

## Time and Repairing the Schwarzschild Solution

loopdoctorFebruary 18July 111Level II Advanced

In his theory of General Relativity, Einstein replaced the Lorentz transformation by the Minkowski formula. He also introduced the variable speed of light in gravitation. This is unnecessary and untenable: it is in conflict with Noether’s theorem on energy and momentum conservation. The authors use the ‘time’...

## Gravitation not acceleration influences the clock.

loopdoctorFebruary 15February 171Level II Advanced

How do you interpret the equivalence principle of gravity and acceleration? Einstein said: standing in a hypothetical closed elevator, you cannot determine whether you hang still and feel the effect of gravity of a planet nearby , or you feel the same effect caused by the elevator accelerating out in space. What...

## Shapiro annihilates Eddington’s “drop the suffix”

Long after Einstein’s death, Shapiro sent a radar signal to Venus, in its position opposite of the sun, and half an hour later received it back. With this astonishing experiment he proved part of the delay (190 microsec) was caused by the gravitation of the sun. Eddington, expert in Einstein’s theory of General...

## Albert Einstein’s space-time and the speed of light

loopdoctorDecember 12February 272Level II Advanced

Albert Einstein (1879 – 1955) was a pioneer of space-time. In 1905, he published his theory of Special Relativity, in which he discovered the energy in mass (E = m.c^2) based on the constancy of the speed of light to all observers. He also introduced time dilation (time going slower at high speed), based on the...

## Emmy Noether, the ignored scientist

loopdoctorDecember 4February 190Level I Student, Level II Advanced, Level III Doctor

It all starts with Emmy Noether (1882 – 1935), a brilliant mathematician, creating one of the pillars of physics: defining reference frames within which energy and momentum conservation can be proven. In 1918 Noether’s theorem was published, more than a year after Einstein published his theory of General...
