  Time is relative. So, the electrons might experience a different “time” because they are moving closer to the speed of light, but they cannot traverse further in time. The twin paradox is interesting because humans change as time goes on. The internal changes a human experiences as they experience time dilation is what we really are measuring. If the twins were both frozen in time, we wouldn’t really care that they experienced different time references during their trip.

  The electrons are basically “frozen in time” in this regard. The information they carry isn’t changing in their relative frame. So the end result isn’t super interesting. If the electron changed over time - and we moved it close to the speed of light - that change would be relative. The information we sent would be different than when it arrived.

  In other words, they do experience different time frames than something 0.00000001c, but since they don’t change at all it’s not really meaningful that they are - perhaps - less “aged” by the time they reach their destination than we are.

  Off lights let you know if it’s broken. If it’s on, it’s obviously working. If it’s off and the light is on, it’s getting power. If it’s off and plugged in, but not displaying the light - that indicates it’s broken or not getting power.

  I know what you mean. I wish more stuff could just be packed in glass jars with the little popping seal. If it’s popped, it has been opened. I don’t know if everything can handle the pressure difference… But it seems ideal. Plus then the glass jars and aluminum lids can be recycled.
