To many physicists, while we experience time as psychologically real, time is not fundamentally real. At the deepest foundations of nature, time is not a primitive, irreducible element or concept required to construct reality. The idea that time is not real is counterintuitive.
Q. What is social construction of reality theory?
The term social construction of reality refers to the theory that the way we present ourselves to other people is shaped partly by our interactions with others, as well as by our life experiences. …

Q. Who invented the concept of time?
The measurement of time began with the invention of sundials in ancient Egypt some time prior to 1500 B.C. However, the time the Egyptians measured was not the same as the time today’s clocks measure. For the Egyptians, and indeed for a further three millennia, the basic unit of time was the period of daylight.
Q. Does the past present and future all exist at the same time?
According to the block universe theory, the universe is a giant block of all the things that ever happen at any time and at any place. On this view, the past, present and future all exist — and are equally real.
Q. Can the future affect the past?
In the subatomic realm, where the laws of quantum physics make seemingly impossible feats routine, the one thing that we always considered beyond the pale might just be true. This idea that the future can influence the present, and that the present can influence the past, is known as retrocausality.
Q. Can we travel into the future?
Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, traversable wormholes, and Alcubierre drives.
Q. Is a time symmetric interpretation of quantum theory possible without Retrocausality?
Ontological time symmetry Our notion of ontological time symmetry can be formulated without assuming No Retrocausality or λ-mediation.
Q. Where did all the antimatter go?
Matter and antimatter annihilate each other on contact, and researchers believe such collisions destroyed almost all of the antimatter (and a large chunk of the matter) that initially existed in the cosmos.
Q. How will the universe end?
If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.
Q. Is there a parallel universe?
Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. The different universes within the multiverse are called “parallel universes”, “other universes”, “alternate universes”, or “many worlds”.
