Can space time be sensed by Human senses including common sense?

Question

How would a blind man answer this question?

Answer 1

You may be asking the question: Can we see Relativistic Effects at the low speeds of the everyday world.

1 Mass curves space-time. We are travelling through spacetime, even ithough we are stationary with respect to ourselves. We are then just travelling through the time part (of the 4 dimensions). We feel our bodies being deflected by the solid earth, from our curved path through spacetime. This is what we think of as our weight. A blind man has weight.

2 A magnetic field, generated by moving electrical fields can be detected by a blind man when he tries to push two north poles of magnets together. The electric and the magnetic fields are manifestations of each other in time-space.

There are other low velocity manifestations which escape my mind at this time. I can think them through if you wish!

Answer 2

You can clearly percieve space time - it is what is all around you. You cannot percieve curvature of space time. Partly this is because where we live it is minutely tiny, and partly it is because you are an "inside observer" - local curvature is most evident when viewed from outside.

Common sense is a strange term to use. It is historic in origin and came from the percieved problem of our reliance on our senses to say anything about the universe, and the inherent unreliability of our senses (everything could be an illusion). The solution was to rely on observations that could be made by more than one sense, on the basis that it is less likely that two senses would be fooled. Such observations were common to two senses or common sense.

Hi. We are immersed in it, as fish are in water, but don't sense it normally. Time is not sensed, it is measured.
