you can interpret this as you will.Einstein followed the line of reasoning that began with the "happiest thought" of his life. While still at the Swiss patent office, he conducted one of the famous thought-experiments. Einstein imagined a circle spinning in space. The center of the circle did...

@Meir Achuz If what you say is true then permeability should change in the presence of a gravitational field. According to Einstein the value of Pi changes in space because the bending of space makes space non-Euclidean.

Nugatory think we may have a bit of misunderstanding. They call it relativity for a reason. The speed you measure light traveling depends on your reference frame when a gravitational field is present. If you are in the rest frame of the mass that is generating the gravitational field, then the...

Just to be sure. It seems to me that the permeability although it is a constant in free space would change when a magnetic field is applied. As an example the speed of light is a constant in free space until it encounters a gravitational field. Light slows down when it encounters a gravitational...

I noticed while reading else where on the internet that certain materials have a relative permeability for the material. I was wondering since permeability increases in ferromagnetic materials when an external magnetic field is applied I was wondering if that was also true for free space.

In free space does permeability increase or decrease when a magnetic field is applied?

@Ibix You bring up a good point when you ask Why? Because you want it to be. It just seems to me it is a necessary thing. We must be able to travel faster than light or we will never be able to get off the Earth and visit other worlds. Just a side thought. Another corollary to what I said...

Thanks for the replies Perok, Nugatory, IBix, Jbriggs444, and Mister T as for Orodruin your response was of absolutely no value it was presumptuous and curt in other words just saying I don't understand or a question is ill posed is not helpful. Explain in detail like the others have done here...

The ship is moving relative to the Earth at 99.9999 percent the speed of light. I assumed everyone would assume that, sorry for the confusion. @Nugatory Yes but all of the speeds you mention are relatively small relative to the speed of light. I would not expect to feel any resistance in the...

I have a question about Special Relativity. If a person is in a rocket ship traveling at 99.999999 percent the speed of light and they are standing at the back of the ship. Will they be able to walk to the front of the ship or will inertial resistance prevent them from doing so?

First of all I would like to thank everyone for their replies. I thought I would be lucky to get one or two replies. This was a great response. Thank you. To answer the general question of what level I am at. I am into natural philosophy so I do not have a strong background in mathematics. I am...

I am wondering do electrons have different mass when they are in different orbitals? I know the energy levels are different so it seems like they must have more mass at the lower orbitals. Has anyone ever tried to measure the mass of electrons in different orbitals?
