Einstein’s theory of relativity had a significant contribution in the field of science, particularly physics. Our understanding in regards to the world of physics was molded by Einstein’s theory, which was introduced in 1905. The theory of relativity that encompasses Special relativity is the first component of the theory. Einstein’s Special Theory of Relativity illustrates the connection between space and time among objects that are moving at a constant speed following the same path. Among its most popular viewpoints relates to objects moving at the speed of light. Einstein’s theory of relativity aimed at approaching the laws of physics that were not dependent on the observer’s circumstances. Einstein’s Special Theory of Relativity was not only aimed at the basis of modern physics but particularly illustrating that the law of physics depends on the circumstances of the observer depending on time and space as relative factors.
The theory of Special Relativity portrays the laws of movement at speeds that are close to the speed of light. It was developed to create reliability among the motion laws and laws of electromagnetism. Special relativity makes two proposes: the physics laws are the equivalent for all observers in constant, and the speed of light in a vacuum is steady, despite the motion. One of the results of these hypotheses is that clocks run slower to a moving observer, or time eases back down. Special relativity additionally expresses that objects at high speeds consistently seem shorter toward movement than they do while still (Lear, Fong, Hawkins, Helps & Selby, 2019).
The hypothesis, which interfaces reality with energy, gravitation, and matter, has since helped researchers find dark gaps, make an addition in the properties of the universe in reverse so as to the Big Bang, and verge on seeing hints of gravitational waves resounding from the most past moments of the universe. Before the theory was introduced, the astronomers relied on Newton’s law of motion. Einstein’s theory of special relativity developed an important link between time and space. Therefore the world could be seen through a three-dimension figure. He argued that in case you move quickly enough through space, the perceptions that you make about reality contrast fairly from the perceptions of others, who are moving at various velocities.
Einstein’s theory of special relativity made major changes in science and, when demonstrated observationally, brought the global physicist acclaim. A ramification of Einstein’s work is that special relativistic facts regard time as equivalent. In spite of the fact that the idea of ‘now’ plays the prime and focal part in our perspective on the universe, relativity subverts our instinct and proclaims our universe a libertarian one wherein each time moment is as relevant as the other (Tsamparlis, 2019). Einstein contended that all aspects of the space-time portion exist on a similar balance as each other, proposing that reality grasps past, present, and future similarly and that the stream that is imagined exposing one area as another goes dull is only an illusion.
In conclusion, Einstein’s special theory of relativity is famous for the provision of precise physical phenomena described in the condition that the relative velocity id less than the speed of light. According to Einstein, the abnormal behavior of time and space is just obvious when you’re moving in motion close to that the speed of light, so nobody had ever watched it previously. Einstein’s Special Theory of Relativity aims at accomplishing the approaching the laws of physics that are dependent on the observer’s circumstances through a phenomenon referred to as “time dilation.”

In philosophy, presentism is the view that neither the past nor the future exists but only the present. Presentism attempts to present a reality aside from what is known or said about. In his manuscript, Einstein describes the relativity of simultaneity as one important result of the theory of relativity. The word ‘now’ for a Presentist is the same as the word here, and talk of the past and future is the same as like referring to different directions in space
Individuals are negligible to what their realities consist of. The hypothesis of simultaneity argues that what is real cannot depend on a single moment of time. This theory also seems to favor the block universe, which assumes that the universe is untimely.
Simultaneity also contradicts this view and refers to it as the tenseless way that affects our view of time, according to which all events normally occur, regardless of the past or future. Albert Steins says that presentism is an assumption about people’s concerns with nature and in relation to being and that nature consists of only the present moment, and therefore goes against the tenseless view of time, and negates the talk of times such as the past and the future.
Einstein also argues that presentism threatens to put out the business of historians. He argues that, at worst, presentism encourages moral complacency self-importance and self-praise. That translating the past through our present eyes constantly causes us to count ourselves morally superior. Since most times, our past occurrences constantly fail to measure up when compared to our present-day standards. He insists that one must keep a good tension between the present concerns in regard to the past as both are essential for good history. As respect for the past helps us to look further than only our present-day concerns us to see beyond our present-day concerns backward and forward.
Kristen (2020), the reality is a continuous obstruction, and that every event in this block is stationed in the previous time, apart from those circumstances that take place in a natural way. There is a slice at the end of each edge of the obstruction, and that if the obstruction continues, where a new slice is added, occurrences that were at the very of the block size to be in the existential present and become part of the experimental past. And as time moves on, the present changes as a higher number of reality slices are added to the summate of what is already there. That is when new moments occur, they have included in the empirical present and the occasions that had occurred before they become part of the objective past.
According to the relativity theory of simultaneity, there is no unique way to divide time into spaces. She argues that, for the presentism, matters are not straightforward, that he is committed to the existence of things that are as if they are not, relative to his existence. This argument tends to go against both the ontological and dynamical claims of the presentism by suggesting that there is a moving present, and it, therefore, requires the events of the objective present and one that is no there to be a subsequent time there is a different event in the objective present. And hence individuals ought to accept that all the events are truly simultaneous and that therefore the non-present events also exist.
In conclusion, presentism besets us is two ways: The likelihood to elucidate the past in present times and the general displacement of historical concerns towards the simultaneous period of time and away from the relative past.

The special theory prior to relativity is not absolute or complete as it relies on the viewer’s point of view. Based on this thesis, it is hard to tell whether two events that occur do so at an equal instance or if these incidences are disconnected in space. According to Hendrik Lorentz, a mathematician form of the relativity of simultaneity, the concepts of this theory are bases on the aether but are undetectable from the perspective of the watcher.
Albert also derived the claims of this proposition from the assumption that the constancy of the speed of light seen in a void is self- subsistent compared to the comparative movement of its origin. And also, this theory comes in the principle of simultaneity. This theory of relativity also includes the notion of simultaneously, that the occurrence of two affairs, at the same time, inarguably depends on the onlooker’s outlook (Tsamparlis, 2019). This theory makes it hard to tell whether these two different activities that happen concurrently or if they are separated in space and time. The big confusion here is whether the occurrence of these events is or may be in some way the occurrence of these events was accidental. He continues to explain that, if two occurrences that are at distinct points in space happen, a time frame that is moving in relation to the first, there is a need to assign different times to the event. In later years, Einstein reduced the aether and disregarded the significance of the special theory of relativity. He deduced this theory on two major assumptions that; the principle of relativity applies in all inertial coordinate systems and that the constancy of the velocity of light detected in an empty space is independent of the source of the relative motion.
The principle of relativity is described as one of its observers, and their events are relative to one another and aren’t the same as any other’s events. This is to means that all viewers are transposing at a steady rapidness, and in order to measure the same quickness of how quickly these incidences are moving, they must accept the other principle as a truth that time and space are not self- reliant. This can be expressed by observing an example he gave on tests in which there was a fixed onlooker, a source of light, and a rocket ship propelling towards the source of light. The two observers are linked by a coordinate, or space-time, transformation (Einstein, 1997).
This rule then illustrates that regardless of how fast the rocket is impelled, both watchers must measure the same speed of light coming from the source and the only way this can fail to happen is if the clock of the static looker and that of the rocket watcher are clacking at a different rate. The experiment, therefore, provides enlightenment on three issues that conclusion can be based upon; People live in a space-time continuum universe; the first three extends relate to space while the fourth one is time.
In conclusion, presentism takes us back in two ways: One is the aptness is to demystify the past using our present times and the general shift towards the historical interests towards the current period and distantly from the recent past, hence relativity of simultaneity poses a problem for presentism. Individuals live in four-dimensional space-time, in which the way things occur is fully dependent on the observers overlook. Finally, one must not forget the significance of the velocity of light is in comparison to everyday living.
