What on Earth is time?

Answer 1

In physics, a quantum is the minimum unit of any physical entity involved in an interaction. Since there is no minimum unit of time that is currently known then, no, there is no quantum time.

Aside: If one thinks of the term "quantum" more colloquially then you might say that it is a unit that is synonymous with very tiny therefore you could call a short amount of time a quanta of time. Example: In physics, the Planck time, (tP), is the unit of time in the system of natural units known as Planck units. It is the time required for light to travel, in a vacuum, a distance of 1 Planck length. Planck time is about 5.4*10^(- 44) seconds. The unit is named after Max Planck, who was the first to propose it.

Answer 2

no no no no no no no no no

Correct, I say. The universe is a single moment. The only constant is change. Time is a thing on the other hand though because it exists inside your head as electrons moving through your brain. It physically exists as an idea, in that respect. Time travel though, is possible, all you need to see the past is a camera. All you need to see the future is your own mind.

Answer 3

if you mean time machine then no. It is only Science Fiction also known as syfy. science fiction is only a theory of scientist. cell phones were only once science fiction.

Answer 4

Well,people assume that time is a strict progression of cause to effect but actually from a non-linear, non-subjective viewpoint, it's more like a big ball of wibbly wobbly, timey wimey stuff.
