Do we live in a 4 or 5 Dimensional Universe?

If Einstein had been told before writing SG and GR, that we live in a 5 Dimensional Universe, in which we can only see or detect the properties of the 4th Dimension, at speeds approaching the light speed.

Would he have given another name to the 4th Dimension, to what we now call Time?

In the quantum world is a clock not just another ruler?

In a quantum world if you try to measure something you affect the result you are trying to measure, including time. - but the same can be said inside every black hole, where there is a singularity, the 4th Dimension is zero, but the Gallaxies still move on.

Any answer to one or all above questions would be appreciated.
