Space and time quanta?

Question

Is there a possibility the space and the time are not continuous, but rather, quantified (only some positions in the space exist, and some instants in the arrow of time) ?

Hopes my question is clear.

Answer 1

1) Yes, but nobody has figured out how to do that, yet. 2.1) Not in science. 2.2) Physics is not mathematics, it just uses mathematics as a language. 2.3) No. That would make no sense, whatsoever.

Answer 2

1. Quanta refers to light.

2.1 Many things are infinite, including decimal numbers between any two consecutive whole numbers such as 1 and 2. Such as: 1.1, 1.11, 1.111, 1.52437' an infinite amount of combinations is possible. There are many more infinities.

2.2 If not? See answer for 2.1.. Do not repeat reading in an infinite loop.

2.3 No.
