| time is what we want most but what we use worst |
Time is passing non-stop, and we follow it with clocks and calendars. Yet we cannot study it with a microscope or experiment with it. And it is still passing. We cannot just say what actually happens as time passes.
Time is represented through changes, such as the circular motion of the Moon around the Earth. The passing of time is actually closely linked to the concept of space.
Relativity, according to the general theory of space or the universe, emerged in the Big Bang about 13.7 billion years ago. Prior to this, all cases were packed into one very small point. That point also contained what later came in the form of the Sun, Earth and Moon - heavenly bodies that tell us about the passage of time.
Before the Big Bang, there was no place or time.
Cosmology professor Kari Enkvist says, "In the theory of relativity, the concept of time starts with the Big Bang in the same way that latitude parallels start at the North Pole. You can't go more north than the North Pole."
One of the strangest properties of time is the fact that it is measured by speed and it also becomes apparent through motion.
According to the general theory of relativity, the evolution of space can result in the collapse of the universe. The whole matter will again shrink to a small point, ending the concept of time as we know it.
"The latest observations, however, do not support the idea of collapse, but rather inter-galactic distances increase at a faster rate," says the Enquistist.
