Question

how time is related to the motion of the universe

Answer 1

HEY MATE HERE IS YOUR ANSWER

IF U WATCH THROUGH TELESCOPE THAN AS YOU LOOK FARTHER YOU SEE MORE PAST AS LIGHT TAKE TIME TO TRAVEL TO YOUR EYES.

FOR EG LIGHT FROM PROXIMA CENTAURI TAKE 4.5 YEAR SO WE SEE PROXIMA 4 YEARS OLD


NOW IF WE ACTUALLY TRAVEL THAN IF WE TRAVEL AT SPEED OF LIGHT WE DO TIME TRAVEL OKKK. IT DONT REQUIRE THAT TO TRAVEL TO C ONLY TRAVEL TO 95 PERCENT SPEED OF C TIME DIALATION WILL TAKE PLACE .

THANK YOU

Answer 2

What is "TIME"?
Time is a real phenomenon a continuous change through which we live. Time becomes evident through motion; sunrise sunsets, night and day, the changing seasons, the movement of the celestial bodies all is indicative of continuous change. The aging process is a reminder that molecular motion and interactions are also at work and are a part of time. Other important aspect of time is presence of motion of particles like photon and the motion at the atomic level. Ultimately, an often overlooked but very important aspect of time is that forces also act in time.  

So far so good, but here is where everything turns: there are many approaches toward understanding the phenomenon of time. We, as individuals, perceive time as past,present and future, but in physics time plays a major role in measurement of motion and forces. Einstein’s relativity introduced the concept of "slowing of time" in motion and gravity, which have been precisely confirmed.

To give it a better understanding, imagine two objects moving in orbit around each other in space. Lets suppose we are on a distant observation point, with a fixed time- a time we can precisely measure based on our own perception of it -. Then, from there, we observe time to get slower in the area where these two objects are moving. What do you expect to be perceived? Do you expect to see slower motion? Maybe should also observe proportionally weaker (gravitational) force (otherwise the objects will get pulled together, right)? Or, maybe, if we observed faster time instead, would you expect to see faster motion and stronger forces to keep the objects from flying apart? And, to complete the scope, if we observe time stopping, then the motion should also freezes, as forces will become zero, right? Well... All wrong! Simply because the increase or decrease in strength of forces only occur in relation to the fixed time from where we are making the observation. From the point of view (time) of the orbiting objects, neither motion nor force has changed. As this thought experiment also can be extended to particles held together by electromagnetic forces, we can say that time involves both:motion and forces.

That explains how we perceive change at a "sharp focal point": the present. As such,past is just memory and future is non existent, which are mainly a mental projection based on past experiences and sole observations. The passage of time, and the feeling that past and future have some spacial existence, are illusions created by our mind trying to explain a world filled of constant changes. 

However, with the publication of the special and general relativity in early part of 20th century, which implies the revolutionary concept that time can be slowed, it all changed. This is extremely important, as if we know the cause of slowing of time then we can potentially know the cause of time itself.


"TIME" as a Block of Universe
Every event in time has a place like feeling to it, giving support to the block universe view of time (in which time is fixed and laid out like a time-scape). In the block universe, past, present and future exist together superimposed in differentdimensions. This view of time suggests that dinosaurs are still alive and roaming the earth in other time dimensions; so are multiple copies of us and the whole universe (the Multiverse Theory). As "crazy" as it may sound, this view is reinforced by Einstein’s General Relativity (GR) in which time extends as the fourth dimension, from the past to the future. In fact, lack of simultaneity in Einstein's SR, and an interpretation of the Lorentz transformation equation (known as the Rietdijk–Putnam argument), also promote this view to explain the Andromeda paradox as an alternative reality existing in a different time dimension.

So, based on all that, "time" in the block universe is laid out as time-scape similar to landscape; future and past already exists and there cannot be a free will. Even in the smallest duration of time in a block universe there should be infinite number of copies of everything including the whole universe. However, block universe leads to a few problems and paradoxes... How do we explain the origin of universe as all parts of the block universe exist all the time? If there is a big bang in block universe then even now it exists. If time-scape is already laid out then what causes us to move through this time-scape? How does our consciousness move across time? What makes it move and why we cannot willfully move it anywhere anytime?


"TIME" as result of the Big Bang
On the other hand, most cosmologists believe that the universe originated in an event called the Big Bang about 13 billion years ago. As such, we live in an expanding universe and the galaxies are receding from each other as a part of the universal expansion. Microwave back the "ground radiation" which is a relic from the Big Bang being extensively studied by many NASA and European satellites.
