Are Length and Time Quantized According to Future Theory?

[Jarwulf]

Are length and time quantized? Is future theory expected to show that they are? Is this quantization real or simply due to the fact that there is no way to measure beyond certain scales?

Are mass and energy quantized in all cases?

Are mass and energy quantized in all cases?

First question - it is an open question. Some theories unifying gravity with the other forces include space and time quantization.

Second question - what do you have in mind "all cases"? Photons are quantized.

So its by not the preferred position?

Physics is not a matter of "preferred position". The theories involved have not reached the point where predictions can be made that can be tested by observations.

look up Planck length and Planck time.
