In classical mechanics, time is something that passes consistently paying little mind to whatever occurs on the planet.
Consequently Newton talked about outright space and total time.
Then again, Einstein's Special Theory of Relativity anticipated that time doesn't stream at a fixed rate: moving timekeepers seem to tick all the more gradually comparative with their fixed partners.
Quantum mechanics doesn't disregard the time all things considered. In standard model, photon doesn't encounter time.
Some new hypotheses recommend that time doesn't exist at the quantum level. The investigation of the quantum universe shows us that time doesn't exist.
It shows us that time is a component of relativity in particular and exists comparative with some discretionary perspective.

1. “Time is an illusion. Lunchtime doubly so,” joked Douglas Adams in The Hitchhiker’s Guide to the Galaxy. Scientists aren’t laughing, though. Some speculative new physics theories suggest that time emerges from a more fundamental—and timeless—reality.
2. One second used to be defined as 1/86,400 the length of a day. However, Earth’s rotation isn’t perfectly reliable. Tidal friction from the sun and moon slows our planet and increases the length of a day by 3 milliseconds per century.
3. This means that in the time of the dinosaurs, the day was just 23 hours long.
4. Weather also changes the day. During El Niño events, strong winds can slow Earth’s rotation by a fraction of a millisecond every 24 hours.
5. Modern technology can do better. In 1972 a network of atomic clocks in more than 50 countries was made the final authority on time, so accurate that it takes 31.7 million years to lose about one second.
6. The world’s most accurate clock, at the National Institute of Standards and Technology in Colorado, measures vibrations of a single atom of mercury. In a billion years it will not lose one second.
7. Until the 1800s, every village lived in its own little time zone, with clocks synchronized to the local solar noon.
8. Thinking about how railway time required clocks in different places to be synchronized may have inspired Einstein to develop his theory of relativity, which unifies space and time.
9. Einstein showed that gravity makes time run more slowly. Thus airplane passengers, flying where Earth’s pull is weaker, age a few extra nanoseconds each flight.
10. According to quantum theory, the shortest moment of time that can exist is known as Planck time, or 0.0000000000000000000000000000000000000000001 second.
11. Time has not been around forever. Most scientists believe it was created along with the rest of the universe in the Big Bang, 13.7 billion years ago.
12. There may be an end of time. Three Spanish scientists posit that the observed acceleration of the expanding cosmos is an illusion caused by the slowing of time. According to their math, time may eventually stop, at which point everything will come to a standstill.
