How Does Michelson-Morley Interferometer Measure Space-Time?

In summary, the conversation discusses the possibility of using warp drive for space travel and the use of a Michelson-Morley interferometer to measure space-time. The speaker expresses skepticism about the device and asks for more information on its validity and the physics behind it. They are advised to research the topic further through online sources and recommended materials. The thread is closed but further questions can be asked in new threads.

I was watching a video about space travel and one of the methods of going into space is using warp drive and to test if warp drive was possible they had to created a device to test if their ideas for warp drive was possible they had to measure space-time it's self and they said a Michelson-Morley interferometer can measure space-time and I am very spectacle about this because nowhere have I ever heard of such a device and can anyone tell me if this is real and if it really can measure space-time can you explain how this is possible to measure space-time and the physics behind it.

If you want to learn what a Michelson-Morley interferometer is, you should google for it. There's a pretty decent wikipedia article, and if you have further questions after reading that and the other stuff that Google will find, you can ask them here.

If the video you were watching says what you say it does, it is garbage and you shouldn't be wasting your time on it. If you want to know more about warp drives, google for "Alcubierre drive" and also search this forum for threads about it. If you want to understand what space-time is all about, get hold of a copy of Taylor and Wheeler's "Spacetime Physics" and start working through it - the people here can help you over the hard spots as you come across them.

This thread is closed, but when and if you have followup questions, new threads will be welcome.

Related to How Does Michelson-Morley Interferometer Measure Space-Time?

1. What is the purpose of the Michelson-Morley interferometer?

The Michelson-Morley interferometer is used to measure the speed of light in different directions to test the theory of the luminiferous ether, which was believed to be the medium through which light traveled through space. Its failure to detect any difference in the speed of light in different directions led to the development of Einstein's theory of special relativity.

2. How does the Michelson-Morley interferometer work?

The interferometer works by splitting a beam of light into two perpendicular beams and then recombining them. The two beams travel different paths, with one beam traveling parallel to the Earth's motion through the luminiferous ether and the other at a right angle to it. If there is a difference in the speed of light in these two directions, it would cause a shift in the recombined beam, which can be measured and used to determine the speed of light in the different directions.

3. How does the Michelson-Morley interferometer measure space-time?

The Michelson-Morley interferometer does not directly measure space-time. However, by measuring the speed of light in different directions, it provided evidence for the theory of special relativity, which states that the speed of light is constant and does not change based on an observer's frame of reference. This, in turn, led to the understanding that space and time are interconnected and can be affected by factors such as gravity and motion.

4. What were the results of the Michelson-Morley interferometer experiment?

The results of the experiment showed that the speed of light was the same in all directions, regardless of the Earth's motion through the luminiferous ether. This was contrary to the expected results if the ether theory was correct. These results were a key factor in the development of Einstein's theory of special relativity, which revolutionized our understanding of space, time, and the laws of physics.

5. What impact did the Michelson-Morley interferometer have on science?

The Michelson-Morley interferometer had a significant impact on science as it provided evidence for the theory of special relativity, which has since been confirmed by numerous experiments and is now a fundamental principle in modern physics. This experiment also paved the way for further studies on space, time, and the nature of light, leading to groundbreaking discoveries and advancements in our understanding of the universe.
