    This would certainly contribute to the faster rate of escape. Actually, not only would the diameter of the pores increase due to the increased surface area, but the length of the pores would also...

    I was thinking the elevated temperature would cause the stretched rubber to become softer and more porous, especially to the rather small helium atoms.

    I don't think so. If we assume the daytime temperature is about 25C and the temperature inside the trunk is about 50C, then it may seem that the trunk is much hotter than the outside air, but one...

    No. One can regard person A as in a single inertial frame that passes planets A and B rather than performing any acceleration at planets A and B. The resolution to Scheuerf's problem lies in the...

    By presuming that matter actually causes spacetime to bend, you are assuming that matter and bent spacetime are distinct entities. An alternative perspective is to consider that the bent spacetime...

    I was introduced to matrices as part of the school curriculum when I was 8 years old. I was taught how to add and multiply them but not why they are useful. It wasn't until my senior year at high...

    The cessation of entanglement by measurement doesn't pertain to the delayed choice eraser experiment because each particle is measured only once. If each particle were measured in two incompatible...

    It's not clear to me the answer to your precise question but the delayed choice quantum eraser experiment involves no new physics beyond standard quantum mechanics. However, I will remark that the...

    If you move towards a mirror, the light you emit is blue-shifted in the stationary mirror frame. This is reflected unchanged, but because you are moving towards the reflected light, that light is...

    Parallel to the surface is an important qualification because motion of a mirror normal to its surface does affect the reflected light.
