  1. The past is what happened before the current moment, and the future is what will happen after the current moment. In physics, there is no concept of the current moment, where all moments of time are equivalent. It turns out that the past and future are exclusively anthropic entities that are closely related to the phenomenon of thinking. For example, the past is everything that happened before WE looked at the clock and took its readings. Without a person, the past and future do not exist. Also without a human, bam!! the age of the universe doesn't make sense.

  2. All that really matters is that if you jump out of the window , you'll hit the asphalt and die. That is, the future will exist in any case, regardless of reflection. And most likely, you will have time to remember moments from the past that don't seem to exist anymore, but which invariably led you to this fall.

  3. There is only the present. And in this present, we can scroll through pictures about the future and the past in our head. But no matter how you turn around, we will only have the infinite now on our hands.

  4. And why does no one consider it from the point of view of relativity? While the light reflected from an object reaches our eyes, time passes, so we see all objects as they were in the past. That is, literally, for each material point there is its own time system. And there can be an infinite number of such systems in the universe. In this case, each point is located in “its own present”. If we conditionally take a person and an object as two points, then the person in his time system, in the present, sees the object in the past, and in the same way with the object. So, we can already say that time is not invented by man, since we observe certain phenomena associated with it.�
    The question is actually very complex, no one can say exactly how time works, what it is, and whether it exists at all.

  5. Only the past and present exist in the time format. The future is a convention that can neither be confirmed nor proven.

    If we talk about the physical existence of the past and the future, this is impossible. We are in three dimensions: time, space, and matter. One cannot exist without the other. Therefore, if you want to go back in time and you succeeded (conditionally), another (parallel) reality will appear in the Universe, which will lead to the Universe's doubling in size.

    Simply put, if you want to go into the past or the future, you need to carry time, space, and matter with you. And this, alas, is impossible.

  6. Yes and no.

    If we talk about time in the day/month/year format, then these concepts were introduced for the convenience of life and are tied to the movement of the Earth.

    If we talk about time as a physical quantity, then the question boils down to understanding what physics is.
    In most people's minds, real physics is what they can “feel”. For example, values such as mass, volume, and temperature. We can't touch momentum, moment of inertia, or time, but that doesn't make these quantities any less or more real. All the terms listed above were introduced by a person to build a model of what is happening around us, so, in a sense, they are all invented (I advise you to Google the definition of mass, everything is not so simple there).


    1. The concept of the past and future are created by man.
    2. All concepts are created by man.

    Further information for advanced users:

    Modern physics uses time as an additional coordinate to the usual three (length, width, height; x, y, z). Here it is already clear that the question of the existence of coordinates is actually incorrect.
