## What is time? definition of time

What is time? definition of time ) This is the question that scientists dread to be asked especially in a public setting by extremely inquisitive young students. We have learned to measure and calculate it relative to the natural arrangement of known and visible celestial bodies. This is the ultimate question you ask a theoretical astrophysicist if you want to see them shake in their pants. To this day time can only be described by the measure of elapsed period using the SI unit, Seconds. It is the only SI unit that is freely allowed to shift depending on subject topic. For example in astrophysics, to measure distance between galaxies it would be impractical to use seconds as the measure of time it takes light to travel between the two galaxies2. One problem is that time to a philosopher is something different from time to a physicist. The reason being that a philosopher is likely to want to articulate what we feel about time and, if possible, create a usable definition of all those woolly ideas we have about time & quot; flowing & quot; or & quot; transcending & quot; or, if the philosopher is not of an analytic bent, paint a picture in half-formed concepts – to the despair of physicists who prefer to characterize time by objective experiments.

#### What is arrow of time? definition of arrow of time

It means time only goes one way. It always gets later. It never gets earlier. The physics of ideal solid bodies can go in either direction. If you have a billiard table with no pockets, and one ball on the table, and you hit it and watch it bounce off the sides, you could theoretically hit it back along the same path. That’s Newtonian mechanics. But something different happens when the table has pockets. If you hit a ball and it falls into a pocket, its energy is dissipated as heat (imperceptibly) in the pocket. There is no way to gather that heat energy back into the ball to lift it out of the pocket and roll it back to where you hit it. That’s thermodynamics. The term “arrow of time” was coined in 1927 by the British astronomer Arthur Eddington, pointing out the paradoxical difficulty of reconciling these two formulations.

What is time dilation? definition of time dilation

Time dilation is a phenomenon in which a person finds a clock or other time device similar or identical to their own ticking at a slower pace; therefore making the observer believe that time has & quot; slowed down & quot; for the other clock; but in actuality, time passes at a constant rate; it just true for the observer’s frame of reference.

What is time travel? definition of time travel

Time travel is not too complicated to understand. You see it actually has a lot to do with the after life. Once you die there will be no time in existence. So really all you have to do (which some people find impossible, and would take a lot of research) is get into that state. The state in which there is no time, there for you could time travel to whatever point in time. Albert Einstein had came close to doing so in 1943. In 1943 Einstein discovered facts, and had theories close enough to try an experiment most commonly known as, The Philadelphia Experiment. Einstein used a boat that was used in the Revolutionary War, he somehow (how is unknown) made the boat appear to leave and come strait back. The navy did the experiment and most lost their lives. Einstein did not participate in the experiment because of one of his theories: human molecules are not strong enough to stand teleportation of any kind. This led to anonymous amounts of limbs of the naval soldiers stuck in the ship. Now your probably thinking, & quot; well how did this happen ? & quot; Einsteins theory was correct the molecules from humans, and the molecules from the ship collided during the process of teleportation. Now all I have to say to this day, please to all the people in the world don’t try anything like this you may end up with your hand stuck in something. This is very dangerous. The reason us as the people don’t know any more than this because someone might try and do this again. If this did happen again it would most likely result the same way it did in 1943. This is a very dangerous thing than what it seems like in movies, books, and fictional articles. Do not try this at home, time travel and teleportation are two things that can put the people of the world in danger.

What is time perception? definition of time perception

There is time as we normally know it and there is no time which is the ultimate reality when our awareness is free in its natural, expanded state. We all have had experiences of “no time” when we forget how long we are in an experience which absorbs all our awareness. Where did the time go? How long has it been? There are people who have been declared clinically dead for only a few minutes but swear there were in “heaven” for many days and  proceed to describe story after story of what they experienced. Many have had a vacation which seemed timeless or time spent with special partner or friend where time was lost in the abundance of what was happening. Indeed time can be eaten, yes gobbled up, devoured, made to disappear as awareness in its expanded state eats away the constricted awareness of thought, ordinary reality, time passing lazily along. Time is eaten up, swallowed whole in awakened awareness where there is no border, no boundary, no limit, only vastness, presence, unending space. Here there is no time.
This awakened awareness is not theory but literal experience as mind full reality is replaced with heartfulness. The step after step of time, our thoughts clicking one after another, disappears when we find this safe place in our hearts. Silence, pure being, infinite awareness and whooosh no time, only awareness, connectedness, no self, simple peace…
Ultimately there is no time as many of us can swear to as our bodies say we have been around for many years but our awareness feels there is no age. We are forever young even if we don’t look it! The body may age but awareness? Time will tell they say but many of us already know. Time has already disappeared. There is no time. What is perceived as time is just a gimmick, a constructed reality, a temporary game our personality lives by while our greater being, our infinite being watches, plays, and swims in a much larger ocean.

The definition of  beginning and end of time

Everything is based on matter in motion. It is matter in motion that shows that there must be space and time, else motion would be impossible. Matter itself is eternal, it is infinite and has no begin or end. Therefore also time and space are infinite. No begin or end to space and time. But take care: we don’t see ‘matter’ as such, we only see finite material configurations. By necessity, a finite material configuration has a begin and an end. But such as begin is not a begin in or from nothing, but from previous material forms, and like wise the end is not an end in nothing, but into something else. If we exclude the possibility of ‘self-causation’ (something emerging from nothing) and closed causal loops (something causing itself), then it would lead to the idea of the eternity and infinity of matter, without begin and end. If we take the observable universe (or a finite extension of it) as a finite material configuration, then sure, that too had a begin in time and was caused by some material causes prior to it. Time itself did not begin

Firstly, that notion is a misconception, because the begin refers to events happening in time. A begin of time can not be an event itself, that is self contradictionary.
Secondly, you can not go (backtracking a physical model of the universe to the past) from the present observable universe, using valid theories and methods, back to a point of zero dimensions, without breaking one or more physics laws. So it is invalid to derive that the ‘universe’ would have started (begin of space time and matter from nothing) at some finite time ago.
The idea of an absolute begin of time (and space and matter) thus does not belong to physical reality, it is a doctrine from philosophy, that has been put in by hand by theoretical physicists…
They claim that physical laws existed prior to the universe, and allowed the universe to create itself ‘from nothing’. See More here
