  1. There is no reliable answer to this question, but there are studies and scientifically based assumptions.

    The Planck length is a natural unit of length that imposes restrictions on the accuracy of measuring the position of physical objects (no position in space can be measured with an accuracy exceeding the Planck length). If the theory is correct, then this limitation is fundamental and does not depend on the level of development of technology or the accuracy of devices, it is” sewn ” into the very structure of space-time. Thus, distances less than the Planck length are physically meaningless. This distance is approximately 1.6 * 10 ^ (-35) meters and can still be considered a quantum of space.

    However, in June 2011, a group of scientists from France, Italy and Spain stated that, according to their calculations, the “grain of space” is absent or at least does not exceed 10^(-48) meters, which leaves the question open.

    From the Planck length, the Planck time is easily deduced – this is the time it takes for light to overcome the Planck length. It is approximately 5.39 * 10^(-44) seconds.
