  • higher density in the moving block due to the Lorentz contraction. Another way would be that mass need to be multiply by gamma which it make it higher too

    So the dynamite is hooked to the pole. It has the same perspective than George claiming that the barn is moving and they are at rest. In their perspective the pole never fits inside the barn (that is Lorentz contracted) so the dynamite won’t explode. Imagine the dynamite as a living being who will trigger itself if the pole where it is hooked to fits in the barn, this will never happen so the dynamite won’t trigger itself.

    No, the base of the mountain will appear shorter from George’s perspective keeping the same height. So for him sides will have stepper slopes than for us that we see the mountain at rest. Lorentz contraction

    Agreed with previous responses saying no, and to add something else or different…
    From your own perspective your clock ticks normally so you don’t. From others perspective if they claim you are in motion then they will see your clock ticking slowly and as the elapsed time will be less then ,if this is the case, you are not living longer, instead you are living at a slower time rate (they will see your life in slow motion).

    I feel happy we are far away from moving or travel at speeds close to the speed of light. It would be a totally different world/universe and we would need to understand time and events in a completely different way that what we have today. Syncing with events, objects and people at those speeds where all this relativity become evident would be that hard that we will need, at least, really special clocks to make it work.

    Day and night may be an incomplete answer, also seasons as a reflection of the non-perpendicular angle between rotation axis and the Earth’s orbit complements litle more the first statement.
    A test with Foucault Pendulum is good evidence showing that because the Earth spins then the pendulum does not swing perfectly back and forth instead the oscilation plane also rotates a bit with the planet rotation
