The Evolution of Humanity – A Step Towards Relativity
The dawn of the 19th century marked the end of the Newtonian era and the infallible “classical mechanics” when in the year 1905 a patent clerk named Albert Einstein published his three groundbreaking research papers that transformed the way we think about the universe. Before the theory, scientists believed that space and time were different entities and thought that the laws of reference frame (as described by classical mechanics) were almost ubiquitous in both their precision and their applicability, a conclusion that it lasted a short time until the experimental results proved the important consequences that deviate from the theoretical ones.
Einstein’s classification of the theory of relativity was broadly divided into two parts: the special theory and the general theory of relativity. According to the theory of special relativity, the velocity of the particle is independent of the chosen frame reference thereafter, this can be understood with a basic example of two trains A and B speculated in the neighborhood with a frame of fixed reference attached to any. of the trains, their correlated movements, and the perceptions of the two observers sitting in any two correlated trains. It can be inferred that the relative speed of the train turns out to be almost double for two trains moving with the same speed towards each other. However, if we were to view the whole scenario in the context of the speed of light, an estimate involving twice the speed of light is clearly an ambiguous and absurd result and seems to violate the laws of general relativity given by Einstein. These interesting deductions also gave rise to a new phenomenon, “time dilation”, formulated by Einstein on the basis of the famous investigations carried out on space-time by HA Lorentz and described in his three famous equations, “the Lorentz transformation “. The theory was further supported through similar results obtained using length contraction and the mass-energy relationship.
To this day, the universe contains numerous structures. There are various effects of these structures in the universe. For example, if there were a large mass of an object that was as large in size as a planet and a domain of notable intergalactic boundaries. This colossal nature will cause a change in the curvature of space-time (usually the curvature of space-time is flat due to the inflation of the universe. However, this is the separate field) leading to excessive curvature of the structure of the space. space time. and consequently, slowing down the speed of time. Day-to-day examples include a nanosecond time dilation in GPS systems compared to clocks on Earth, a black hole, a super-condensed and compacted mass of infinite matter with its dimensions approaching the singularity, will tend to have more effect in time because of its significant effect on the fabric of space-time. The theory of general relativity repudiates the presence of any force such as gravity and sees it as the natural movement of an object between geodesics in space and time.
If something doesn’t fall (for example, if it rests on a table), it is being accelerated away from its natural motion by the compression of the table surface below it. This table force is the only real force present. There is no such thing as a gravitational force. Massive things are heavier because the table needs to apply a greater force to accelerate them away from their natural motion. Thus, gravity turns out to be a fictitious force like the centrifugal force. We feel centrifugal force when a car turns a corner, but in reality our body is just trying to follow its natural movement (a straight line) and the car has to push us sideways. Similarly, we feel gravity pulling us down, but all that really happens is the ground pulling us up against our natural movement. This natural movement is called Geodetic and draws its greatest impact from Relativity.
