In summary, Einstein's thought experiment 'Einstein's mirror' demonstrated the impossibility of an object with mass traveling at the speed of light and was a key factor in his rejection of the hypothesis of an all-pervading aether. This was determined through the use of thought experiments, as technology at the time did not allow for actual experimentation at such high speeds.

I have just recently read about the thought experiment called 'Einstein's mirror'. I understand that the imaginary experimenter loses his reflection in the mirror when he travels at the speed of light through the luminiferous aether. The loss of reflection itself is enough evidence for Einstein to reject the hypothesis of an all-pervading aether which carries electromagnetic waves. But as far as I know, the technology at that time was not sufficiently advanced to allow someone to travel even close to the speed of light. So, how could Einstein have known that he wouldn't lose his reflection were he to travel at the speed of light?

Einstein knew that no mirror would refuse to show his face. :-p

Einstein's conclusion was that it was impossible for him (or anything with non-zero mass) to travel at the speed of light.

That's the whole point of a thought experiment. He could determine what the presumed laws of physics told him would happen without having to actually do the experiment.
 

Related to Einstein's Mirror Thought Experiment: Debunking the Luminiferous Aether Theory

1. What is Einstein's Mirror Thought Experiment?

Einstein's Mirror Thought Experiment is a hypothetical experiment proposed by Albert Einstein to debunk the concept of the luminiferous ether, which was believed to be the medium through which light waves travel.

2. How does the experiment debunk the luminiferous aether theory?

In the experiment, a beam of light is directed at a mirror that is moving at a constant speed. According to the luminiferous aether theory, the speed of light should be affected by the motion of the mirror. However, the experiment shows that the speed of light remains constant regardless of the motion of the mirror, thus disproving the existence of the luminiferous aether.

3. What was the significance of this thought experiment?

This thought experiment was significant because it provided evidence for Einstein's theory of special relativity, which states that the laws of physics are the same for all observers in uniform motion. It also revolutionized our understanding of the nature of light and paved the way for further developments in the field of physics.

4. Was the experiment actually conducted?

No, the experiment was purely hypothetical and was never actually conducted. However, it was an important thought experiment that helped to disprove the concept of the luminiferous aether and support Einstein's theory of special relativity.

5. How did this thought experiment impact the scientific community?

This thought experiment played a crucial role in shaping our understanding of the fundamental principles of physics, particularly in the fields of special relativity and the nature of light. It also sparked further research and experiments that led to groundbreaking discoveries in the field of physics.
