## Schrödinger’s cat equation and **What is Einstein’s general theory of relativity?**

**Special relativity**

The fundamental aspect of relativity is governed by several aspects, like space and time, along with the mass of an object. Renowned physicist Albert Einstein in 1905 was published a research paper which provided an in-depth description of how speed affects mass, time, and space, which is called the special theory of relativity.

This theory establishes a correlation between matter and energy, which highlights a way for the speed of light (3 X 10^8 meters per second) to induce a small amount of mass, which can be interchangeable with a significant amount of energy (E). This is defined by the equation, which is widely recognized as E=MC^2. The special theory of relativity is generally applicable to particular cases and is mostly utilized when discussing smaller objects that travel very fast, considerable energy and astronomical distances.

By adding gravity to this theory, Einstein developed a notion regarding general relativity, which was published in 1915. According to the special theory of relativity, when objects are close to the speed of light, the mass of objects becomes infinite, and the energy required to move such objects also substantially increases. As a result, it is impossible for any object to travel faster than light. Which is known as the cosmic speed limit.

**General Relativity **

The theory of general relativity defines how gravity affects the fabric of space-time. However, special relativity signifies that space and time are inevitably connected, and Einstein spent many years trying to figure out that massive objects could wrap the fabric of space-time in a distortion, which is known as gravity. Einstein in his theory of special relativity, shades light into the laws of physics, which remain the same for all non-accelerating observers.

This theory also indicates that the speed of light in a vacuum remains constant with respect to the speed of the observer. Einstein established that space and time were intertwined into a particular continuum, which is recognized as space-time. Since Einstein worked out the equations for a general theory of relativity, he understood that massive objects could distort space-time, which constructs the idea for the theory of general relativity.

**Quantum Mechanics and Theory of Relativity **

The cosmos is segregated into two scales: one is very large, where classical mechanics are applicable another is very small scale, where atoms and subatomic particles deepen the understanding of quantum mechanics. These two aspects have forced scientists and theoretical physicists** to **comprehend the facets, which shape the destiny of modern physics. Furthermore, many theoretical physicists tend to describe classical and quantum mechanics, which significantly differ from each other. We are aware of how the laws of motion and gravity work, which was critically described by **Isaac **Newton**;** likewise, the laws of Thermodynamics have also increased our understanding of how energy and heat transfer in a system.

However, there are many mysteries regarding the nature of quantum particles yet to be disclosed. The standard model of physics and quantum mechanics has provided an in-depth comprehension of the forces of nature and the nature of subatomic particles. Besides, string theory tried to present a unified theory which might change the perception of scientists towards the observable universe. In contemporary years, many scientists tend to combine general relativity and quantum mechanics to understand the laws of quantum gravity. The Unification of these two theories could alter our perception of towards observable universe.

**Theoretical base of Schrödinger’s cat**

Renowned physicist Erwin Schrödinger attempted to conduct though experiment which is known as Schrödinger’s Cat, which was proposed by him in the year 1935. This thorough Schrödinger’s cat experiment was planned to shed light on the complex behaviour of quantum particles by interpreting quantum theory. As scantiest are widely familiar with classical mechanics, which widely differ from the behaviour of quantum particles such as Quarks, Fermions, and Higgs Boson, which are governed by the quantum rules has extended the base of modern physics, which comprises special relativity, quantum mechanics that can be explained through Schrödinger’s cat equation and general relativity.

Deep down in Schrödinger’s cat experiment, Erwin Schrödinger imagined a box that contained a radioactive atom, a vessel of poison and a cat**.** According to the quantum rules, radioactive atoms can either decay or not within a specific timeframe. It is worth pointing out that when radioactive decay occurs, it breaks the container within the box, which liberates the poison and kills the cat.

If Copenhagen’s interpretation is exact, then prior to any measurement occurring, the atom, along with also the cat, is in a superposition of decayed/ dead as well as not decayed/ alive. This thought experiment of Schrödinger’s cat played an integral role in encouraging different ways of thinking about quantum theory, which also interpreted many world hypotheses, suggesting that the various possible realities of quantum objects crystallized into a parallel universe at the time of measurement.

**What is quantum superposition?**

Quantum mechanics that shade light into the linear combinations of clarifications to the Schrödinger equation and also provide solutions to the equation. Moreover, the Schrödinger equation describes the linear differential equation in time and position, and the absolute state of a system is given by a linear arrangement of all the eigenfunctions of Schrödinger’s cat equation governing that specific system. In general, qubit, which is utilized in quantum information processing, and its state is most particularly a superposition of states |0> and |1>.

Likewise, in quantum mechanics, sub-atomic particles like photons and electrons have wavelike properties that could combine, which is known as superposition. It is often expressed by equations which describe the probability of a particle in a given state. The equation could provide information on the probability of an electron moving at a definite speed, and when an electron is in superposition, its various states could produce separate outcomes, each with a specific probability of being observed.

A superposition of two different velocities or the existence of electrons in two places at once has attracted the attention of quantum physicists to uncover the actual truth behind the strange behaviour of subatomic particles, which is not generally described by classical physics. Which is governed by the law of conservation of energy, Newton’s laws of motion and conservation of mass.

**Could Modification to Schrödinger’s cat equation combine quantum mechanics and Einstein’s relativity? **

Theoretical physicists have projected an emerging solution to Schrödinger’s cat equation, which could allow Einstein’s theory of relativity and quantum mechanics to correlate some aspects which could alter the perception towards classical and quantum physics. However, employing the fundamental rule, which is surrounded by Schrödinger’s cat equation in real-world situations, comes up with challenges when the true paradox ascends.

In addition, describing the entire universe by utilizing quantum principles causes problems since the cosmos seems exclusively classical besides lacks of external observer to act as a measured device for evaluating the states of quantum particles. Nevertheless, a new model might explain the beginning of the classical universe from a quantum superposition of universes. This could be a modification to Schrödinger’s cat equation, which could combine quantum mechanics and Einstein’s relativity.
