The Physical Sciences are branches of science that study non-living systems including Astronomy, Chemistry, Earth Science, and Physics.

Observing a Phenomenon Affects Its Outcome

Observation affects outcome

Observing a phenomenon can affect its outcome (observer effect). In science, this refers to particles existing in a state of probability until measured.

The Universe is Mostly Empty Space

Is The Universe Mostly Empty Space?

The universe and everything in it, including humans, is mostly “empty space.” However, space is not actually “empty,” it’s filled with quantum fields and dark energy.

Energy is Neither Created or Destroyed

Energy can’t be created or destroyed and neither can mass. Although energy can change forms, all energy in a closed system must remain constant.

Are Astrology and Astronomy the Same?

Astronomy is a science that studies celestial objects and the physical universe. Astrology is a pseudoscience that studies celestial objects to predict events.

Time is Relative

Time is Relative

Time is relative to speed and gravity (time dilation), and so is space (length contraction). Light speed is constant for all observers, so time and space can’t be.
