Is time a physical property

Answer 1

It is arguable whether time is a function of matter, or matter is a function of time, since they are interlinked. Matter and the entire universe as we understand it exists in a framework of space-time which exist together and are essentially inseparable. Matter distorts the fabric of space-time. A large enough mass (quantity) of matter can distort space-time to such an extent that it "pinches" down to a single point (a singularity) where the concept of time has no meaning.

Answer 2

Time is a physical property.

Years ago, a second was a specific fraction of a single orbit of the Earth around the Sun. Now a second is calibrated to the natural resonance of a cesium atom (9,192,631.770 Hz). There are atomic clocks calibrated to this located at The National Institute of Standards and Technology in Boulder, CO and at the Royal Observatory in Greenwich, England. Both are so accurate that in 1,000,000 years, they will be off by less than a second. The clock in the NIST is 5 nano-seconds faster each year than the clock in the Royal Observatory. It is a small, but measurable amount.

We now know that time is the 4th dimension. Subject to mass, velocity, and acceleration (a four dimensional cube is called a tesseract). If twins born at the same time conducted an experiment where one stayed on Earth and the other traveled to Alpha Centauri, the closest star system to our own at a little under 4.5 light years away, and returned at 99.9999% of the speed of light. While the twin on Earth would be 9 years older when his brother returned, the brother who traveled to Alpha Centauri would only be about 2.5 years older.

Answer 3

no because how can you measure a rock or an ice-cream be identified as time? Well you can't so time is not a physical property.

Answer 4

No. Frequency is just how often something happens.
