    Time
In summary: It is relative and its relativity is affected by velocity and gravity. In summary, time is a relative concept and its relativity is influenced by velocity and gravity. It is used as a reference point and is considered a 4th dimension in space.

I don't know if this is in the right forum but i was wondering what is time? Does it have any relativity to the things happening in the universe and if not then what the point of it?(other then to get to the doctors on time)

Time is completely relative. it is different for different thing according to one's frame of reference and frame of reference depends on velocity of object. object with larger velocity has slower time than smaller velocity object. We divide the time according to our solar system, what time Earth takes to complete the one round of sun. and what times it takes to complete one round on its own axis, different planet takes different time according to their size and distance. so they have different values.
On larger scale These values can be totally different, another prediction of general relativity is that time should appear to slower near a massive body like the earth.This is because there is a relation between the energy of light and its frequency (that is, the number of waves of light per second): the greater the energy, the higher frequency.As light travels upward in the earth’s gravitational field, it loses energy, and so its frequency goes down. (This means that the length of time between one wave crest and the next goes up.) To someone high up, it would appear that everything down below was making longer to happen.it means time will always be slower near sun than Earth and slower near Arcturus (large star) and slowest near an Antares(largest star). it means massive galaxies have slower time than lighter one and by Hubble's law, galaxy the farther, it has more velocity if it's velocity is near velocity of light, there will be time difference because of special theory of relativity
(time dilation).

There is no particular definition of time...

For the time being : time is a 4th dimension in space.

time is a dimension and a fundamental quantity used as a reference.
 

1. What is the concept of time?

The concept of time is a fundamental aspect of our existence. It is a measure of the duration of events and the sequence in which they occur. Time allows us to organize our lives and understand the world around us.

2. Is time a human construct or a natural phenomenon?

This is a highly debated topic in the scientific community. Some argue that time is a human construct and does not exist in nature, while others believe that time is a fundamental aspect of the universe and is not dependent on human perception.

3. How is time measured?

Time is measured using various units such as seconds, minutes, hours, days, and years. These units are based on the rotation of the Earth and the movement of celestial bodies. Today, time is most accurately measured using atomic clocks.

4. Can time be manipulated or controlled?

While humans have developed ways to measure and track time, we currently do not have the ability to manipulate or control time. However, some theories in physics, such as Einstein's theory of relativity, suggest that time can be affected by gravity and motion.

5. What is the relationship between time and space?

Time and space are often referred to as the fabric of the universe. They are closely intertwined and cannot exist without each other. Time can be seen as the fourth dimension, with the other three being length, width, and height.
