Why in this experiment was it safe to assume that at some time of the year the Earth should be moving relative to the ether with a speed of at least 3x10^4 m/sec??
Well, for that experiment, anyway.Lojzek said:However one must assume that the Earth can not drag the ether along.
Ether is a hypothetical substance that was once believed to fill all of space and allow for the propagation of electromagnetic waves, such as light. It was later disproven by the theory of relativity.
The speed of Ether is believed to be at least 3x10^4 m/sec, which is equivalent to 30,000 meters per second. This estimate is based on the speed of light, which is the fastest known speed in the universe.
The speed of Ether was initially determined by experiments conducted in the late 19th and early 20th centuries. However, these experiments were later disproven by the theory of relativity, which showed that the speed of light is constant and does not require a medium to travel through.
The significance of this speed is that it is close to the speed of light, which is the fastest known speed in the universe. This suggests that Ether may have played a role in the propagation of light and other electromagnetic waves before the theory of relativity was developed.
No, the concept of Ether has been disproven by the theory of relativity. However, some physicists still use the term "ether" to refer to the fabric of space-time and the vacuum of the universe.
