Albert Einstein, a name synonymous with genius, revolutionized our understanding of the universe with his ground breaking work on the theory of relativity. ItÂ has completely changes our way of looking at things. Although it is very difficult to understand Einstein relativity the special and general theory.

But in this blog post, still let us try to understand something through this article albert Einstein relativity the special and general theory.

## Understanding the Basics:

### Special Theory of Relativity:

Albert Einstein introduced the Special Theory of Relativity in 1905, reshaping our understanding of time and space. This theory fundamentally altered the way we perceive motion, demonstrating that time is not an absolute concept and is relative to an observer’s frame of reference.

### General Theory of Relativity:

Building on the foundations of the Special Theory, Einstein unveiled the General Theory of Relativity in 1915. This theory goes beyond the limitations of special relativity, incorporating gravity as a curvature in the fabric of space-time.

It provides a comprehensive framework for understanding the gravitational force as a consequence of mass bending the fabric of the universe.

About four hundred years ago, **Isaac Newton** made an important discovery by observing a falling apple, which is called the **Theory of Gravitational Force**. According to this theory, the material bodies in the universe pull each other with a very slight force. This force was named **gravitational force**.

Due to this force we are able to establish our feet on the earth. And this force is responsible for rotating the Earth around the Sun. Every object present in the universe is moving under the influence of gravitational forces.

Later, some other discoveries have revealed that light also deviates from its path due to the force of gravity. And sometimes it wanders so much that its direction turns back to the same direction from which it had started.

When Einstein studied the universe in the light of these facts, a completely new aspect of it emerged.

**A.** Imagine a point with nothing around it. There is not even space around it. Nor is there any force of attraction or repulsion from outside at that point. Then that point explodes and gets divided into many parts.

**B.** Certainly these parts will start moving away from each other. And for this they will also create the space themselves. Which should be in the shape of a sphere which is continuously expanding like a balloon. And all the parts present inside it will move outwards from the point of explosion in a stair line.

**C.** Bending of Light

Then the direction of their movement away from each other will also depend on the force of their attraction. Then their motion will no longer remain in the straight line. If the group of these points is considered as sky then this sky will not be straight but will be curved.

**D.** Our Universe is also similar in which stars, galaxies and other celestial bodies exist in the form of points. Through the explosion of a point-like extremely hot and dense body, it got divided into innumerable points which are today’s stars, planets and satellites.

**E.** All of them are attracting each other with their respective gravitational forces. Which is less at some places and very high at other places. Einstein’s theory also explains the origin of gravitational forces.

## Imagination of relativity the special and the general theory

Now in topic relativity the special and the general theory, taking our imagination further, suppose that a person (webserver) is present at one of the innumerable points created after the explosion.

Now when he sees other points moving, whatever path of motion he sees will depend on the motions of all those points, and on their forces of attraction changing due to those motions (because this force depends on the distance. Is.).

If to this is added the fact that the line of light, which is the only source of visibility of those points, also deviates from its path due to the gravitational forces present in the sky, then the matter of visibility of things becomes more complicated.

Thus overall in this topic Einstein relativity the special and general theory leads us to such miraculous conclusions. Einstein expressed his theory through an equation whose solution remained a challenge for mathematicians and physicists for a long time.

Later, a scientist named **Schwartzchild** succeeded in getting its definite solution for the first time.

Some strange things emerge when **Einstein’s equations are solved**. Such as Singularity, **Black Holes** vs **Wormhole**.

The speed of light slows down in gravitational fields. That means the speed of time also slows down.

Space-time tells how matter should move and matter tells space-time how it should curve.

At present, many solutions of Einstein’s equations exist which reveal some interesting facts. Like Godel’s Universe in which time travel is possible. That means one can travel in the past or future.

Now let us discuss a small situation.

Consider the above pictures. Suppose a star is located at some distance from our Earth. The light of that star can reach us in two ways. By a straight path. And secondly by bending of light, passing through a heavy body bending of light occurs where light bends the starlight going in some other direction due to its high gravity and sends it to our Earth.

Whereas the beam of light coming from the star is stopped by a black hole which is present between the Earth and the star. Now, when a viewer present on the earth measures the distance of that star, it will appear to be much more than the actual distance because this distance will be measured on the basis of the ray which is traveling through the body and reaching the viewer.

Whereas by passing near the black hole, that star can be reached very quickly. Provided that care is taken that the giant attraction of the black hole does not engulf the traveler. This type of situation suggests the possibility of such shortcuts that can reach any place in the universe much quicker than expected. These short cuts are known as wormholes in the physical world.

This was a simple situation. The situation becomes more complicated when we see that the Earth, the body, the star, the black hole all are moving on their own paths. In such a situation, it becomes extremely difficult to draw any conclusion.

Overall, it can be said that Einstein’s ‘General Theory of Relativity’, created to explain the mysteries of the universe, creates many new mysteries.

This discovery opens a new window to observe the universe, letting us “hear” cosmic events we couldn’t detect before, deepening our understanding of gravity and the unseen cosmic dance happening all around us.

### FAQ 8: What are some of the lesser known facts about the general theory of relativity?

Absolutely! The General Theory of Relativity reveals a strong link between gravity and energy. It tells us that not just mass, but also energy and momentum, can bend and shape spacetime, creating the gravitational effects we observe. So, whether it’s a massive planet or a burst of energy, both have a say in how space curves and how things move around in the universe.

### FAQ 10: Are satellite trajectory calculations based on the relativity the special and general theory?

Yes, indeed! Satellite trajectories do account for the effects of Einstein’s General Theory of Relativity. Because satellites move in high-speed and low-gravity environments, the theory’s corrections help ensure GPS systems and satellite operations remain accurate, considering how gravity slightly bends spacetime affecting their paths.

### FAQ 11: Why is Einstein’s general theory of relativity not considered a law?

Einstein’s General Theory of Relativity is a powerful framework describing gravity but isn’t termed a law like Newton’s laws of motion. Laws typically offer precise formulas predicting exact outcomes, while Einstein’s theory is a complex set of principles explaining gravity’s nature, involving intricate mathematics and variables, making it more a theory guiding our understanding rather than a simple law.

### FAQ 12: How much time did it took Einstein to derive the general theory of relativity?

Einstein spent around a decade, roughly from 1907 to 1915, working on the General Theory of Relativity. It was a long and challenging journey filled with deep thinking, revising ideas, and intricate calculations before he finally unveiled this groundbreaking theory to the world.

### FAQ 13: What are the equivalents in the equivalence principle of the general theory of relativity?

### FAQ 15: Who is conducting an experiment to verify the general theory of relativity now?

Various experiments worldwide continue to verify and explore different aspects of Einstein’s General Theory of Relativity. Organizations like LIGO (Laser Interferometer Gravitational-Wave Observatory) and the European Space Agency conduct experiments detecting gravitational waves or studying cosmic phenomena, contributing to our ongoing understanding and confirmation of Einstein’s groundbreaking ideas.

### FAQ 16: What difficulties did Einstein face in formulating the general theory of relativity?

### FAQ 17: Can an atomic model be built upon using solely the general theory of relativity?

The General Theory of Relativity explains gravity on a large scale, like planets and galaxies, but it doesn’t describe the behavior of tiny particles within atoms. For those, we use quantum mechanics! Combining both theories into one comprehensive model, known as a “theory of everything,” remains a big challenge in physics.

### FAQ 18: Can we derive the general theory of relativity from the equivalence principle?

The equivalence principle was a starting point for Einstein in shaping the General Theory of Relativity. However, deriving the entire theory solely from this principle isn’t straightforwardâ€”it involved more intricate thinking, mathematical equations, and understanding how space, time, and gravity are intertwined on a cosmic scale. The equivalence principle acted as a guide, but piecing together the full theory required Einstein’s deep insights and complex calculations.

### FAQ 19: What is the general theory of relativity in simple English?

The General Theory of Relativity is Einstein’s big idea about how gravity works. Instead of thinking of gravity as a force, it says that massive things, like planets, actually bend and warp the space around them, affecting how everything moves. It’s like imagining the universe as a giant trampoline where objects create dents, causing things to roll around in those dentsâ€”showing how space and gravity are deeply connected.

### FAQ 20: Is there any relationship between quantum mechanics and the general theory of relativity?

Absolutely! While both quantum mechanics and the General Theory of Relativity are brilliant theories, they describe different aspects of the universe. Quantum mechanics explains the world of tiny particles like atoms, while Einstein’s theory focuses on gravity and the immense cosmos. Bringing them together into a single theory remains a quest for physicistsâ€”an attempt to unite these two remarkable ideas into a “theory of everything.”

### FAQ 21: Does general theory of relativity says that there is no such thing as gravity?

Einstein’s General Theory of Relativity doesn’t exactly say there’s no gravity; instead, it reimagines what causes it. Instead of gravity being a force pulling things together, it says that massive objects bend and curve space, creating the effect we perceive as gravity. So, it’s more about how gravity worksâ€”describing it as a result of the shape of the universe rather than a traditional pulling force.

### FAQ 22: Can scientists integrate the general theory of relativity with classical physics?

Absolutely! Scientists have successfully integrated Einstein’s General Theory of Relativity with classical physics in many real-world scenarios. Classical physics, which includes Newton’s laws, works perfectly well for most everyday situations like cars moving or objects falling, while Einstein’s theory takes over in situations involving high speeds, strong gravity, or cosmic scalesâ€”bridging these two theories helps us understand both the everyday and the cosmic.

### FAQ 23: How can the general theory of relativity conserve energy?

The General Theory of Relativity upholds the conservation of energy, but it does so in a different way than you might expect. Instead of energy being strictly conserved locally (like in classical physics), it’s conserved on a larger scale, considering the energy associated with gravity and the curvature of spacetime itself. So, while the traditional idea of local conservation might seem a bit altered, the overall conservation of energy across the universe stays intact in Einstein’s theory.

### FAQ 24: Where is general theory of relativity used?

The General Theory of Relativity finds its home in various places! It’s vital in understanding the cosmosâ€”explaining things like black holes, the expanding universe, and gravitational waves. Plus, it has surprising everyday applications, like fine-tuning GPS systems to work accurately despite the differences in gravity around Earth.

### FAQ 25: What are non-examples of the general theory of relativity?

Non-examples of the General Theory of Relativity would be scenarios where gravity works differently than Einstein’s theory predicts. For instance, in everyday situations where classical physics’ understanding of gravity, like a ball falling to the ground without accounting for cosmic scales or extreme conditions, differs from what Einstein’s theory describes.

### FAQ 25:Â What did Albert Einstein invent?

Albert Einstein didn’t invent physical objects, but his groundbreaking work in theoretical physics led to revolutionary concepts like the theory of relativity, E=mcÂ², and the photoelectric effect. These ideas fundamentally changed our understanding of space, time, and energy, paving the way for advancements in modern physics.
