What is the concept of the theory of relativity?

The theory of relativism often combines two related ideas of Albert Einstein: special connections and general relativity. A special connection applies to all physical events in the absence of gravity. Common relativity defines the law of gravity and its relativity to other natural forces. It applies to the cosmos and astronomy, including astronomy. 
This theory revolutionized theoretical physics and astronomy during the 20th century, replacing Isaac Newton with 200 years of mechanical evolution. Introduce concepts including space-time as a cohesive space and time, correlativity of similarities, mood swings and time maturation, and diminished length. In the field of physics, relativity has improved the science of early particles and their basic interactions, as well as the introduction of the nuclear age. In connection, cosmology and astrophysics predicted unusual star phenomena such as neutron stars, black holes, and gravitational waves.

In 1905, Albert Einstein decided that the laws of physics were the same for all spectators and that the speed of light in the hole was independent of all viewers. This was a concept of special relativity. It introduced a new framework for all physics and suggested new concepts of space and time.

Einstein then spent 10 years trying to incorporate speed into thought and published his theory of relativity dating in 1915. In it, he decided that big things create distractions in the space of time, which sounds like gravity.

Special relativity
First, the natural world does not allow "right" reference frames. As long as an object moves in a straight line at a continuous speed (i.e., without acceleration), the laws of physics are the same for everyone. It’s like when you look out of a train window and see a nearby train seem to be moving - but is it moving, anyway? It would be hard to say. Einstein saw that if the proposal was completely the same, it would be impossible to say - and he saw this as a central goal of physics.

Second, light travels at an incredible speed of 186,000 miles per second. Regardless of the speed of the spectator or the way the object emits light, the rate of light speed always produces the same effect.

Starting with these two calculations, Einstein showed that space and time are intertwined in ways that scientists have never seen before. Through a series of thought tests, Einstein showed that the effects of special relativity are often contradictory - and surprising.
If you zoom in on a rocket and pass a friend on the same rocket but slower, for example, you will see that your friend's clock is slower than yours (scientists call this "extension of time").

Also, your friend's rocket will appear shorter than yours. If your rocket is fast, your weight and rocket will increase. The faster you go, the heavier things become, and the more your rocket will withstand your attempts to make it faster. Einstein has shown that nothing with weight can reach the speed of light.

Another result of the special relativity is that matter and energy alternate with the popular equation E = mc² (where E stands for power, m in magnitude, and light speed is multiplied by itself). Because the speed of light is such a large number, or even the smallest amount of weight equals - and can be converted into - a very large amount of energy. That is why atomic bombs and hydrogen are so powerful.


General relativity
Basically, it is a doctrine of gravity. The basic premise is that instead of an invisible force attracting objects to one another, gravity pulls or twists the space. The larger the object, the more aggressive it becomes.
For example, the sun is large enough to encircle our entire solar system - much like the heavy ball on a sheet of paper that wraps around a sheet. As a result, Earth and other planets move in orbit around orbits.

These outbreaks also affect time estimates. We tend to think of time as a slow walk. But just as gravity can expand or distort space, so it can expand time. If your friend climbs to the top of a mountain, you will see his clock ticking faster than yours; another friend, down in the valley, will have a slightly disturbing clock, due to the difference in gravity in each area. Subsequent tests proved that this was indeed the case.


The development of relativity
Albert Einstein published the concept of special relativity in 1905, building on the many theoretical and powerful findings of Albert A. Michelson, Hendrik Lorentz, Henri Poincaré, and others. Max Planck, Hermann Minkowski, and others did the following.
Einstein developed common relativity between 1907 and 1915, with the contributions of many after 1915. The last general affiliation form was published in 1916. 

The term "theory of relativity" was derived from the term "relative relative" (German: Relativtheorie) used in 1906 by Planck, who emphasized how the theory applied the principle of relativity. In a discussion section on the same paper, Alfred Bucherer first used the term "relativity theory" (German: Relativitätstheorie). 
By the 1920s, the physics community understood and embraced special communication. It soon became an important and necessary tool for theorists and experimentalists in the new fields of atomic physics, nuclear physics, and quantum mechanics.

By comparison, common relativity did not seem to be useful, other than to make small adjustments in predicting Newtonian gravitation. It appears to offer little that could be done in the experimental test, as most of its recommendations were in the star rating. Its statistics seemed complex and fully understood by only a few people. About 1960, the common denominator was between physics and astronomy. New mathematical methods of using mathematics are generally associated and make its concepts easily recognizable. As astronomical phenomena were identified, such as quasars (1963), 3-kelvin microwave background radiation (1965), pulsars (1967), and first black hole nominees (1981),  the theory explained their characteristics, and ratings to them further confirmed vision.


Gravity and relativity
Two things have the power to attract each other known as "gravity." Sir Isaac Newton measured the magnitude of the two objects while making his three motion rules. Gravity between two corpses depends on their size and distance. As the center of the Earth pulls you into it (keeps you sitting down), your center of mass returns back to Earth. But an extremely large body feels unattractive to you, while with your smallest weight you find yourself firmly grateful for that power. Yet Newton's laws assume that gravity is the natural force of something that can cause distance.

Albert Einstein, in his special relativity theory, decided that the laws of physics are the same for all slow-moving observers, and showed that the speed of light within a space is the same no matter how fast the visitor travels. As a result, he discovered that space and time were combined into one continuous process known as space-time. Simultaneous events for one observer may occur at different times.

While working on mathematics with his common sense of relativity, Einstein realized those big things caused disruption during space. Imagine placing a large body in the center of a trampoline. The body presses into the fabric, causing it to shrink. Marble wrapped around the edge would rotate inward, pulling in the same direction as the planet's gravitational pull on the rocks in space.


Evidence for experimental relativity
Gravity loading: The light around a large object, such as a black hole, is bent, causing it to act as a lens for the objects behind it. Astronomers often use this method to study the stars and galaxies behind large objects.

Einstein's Cross, a quasar in the Pegasus constellation, is an excellent example of the illumination of gravity. The quasar is about eight billion light-years from Earth, and it sits behind a galaxy 400 million light-years away. Four quasar images appear around the galaxy because the mass of the galaxy bends the light from the quasar.

Gravity loading may allow scientists to see beautiful cool objects, but until recently, what they saw around the lens remained motionless. However, as light travels around the lens takes a different path, each passing a different time, scientists have been able to see the supernova appear four different times as it is magnified by a huge galaxy.
In one exciting discovery, Kepler's NASA telescope saw a dead star, known as white debris, orbiting a small red object in a binary system. Although the white rock is very large, it has a much smaller distance than its counterpart.

"This approach is equivalent to seeing a 3,000-mile-long light bulb, about the distance from Los Angeles to New York City," Avi Shporer of the California Institute of Technology said in a statement.
Changes in the orbit of Mercury: The orbit of Mercury gradually changes over time, due to a decrease in the space of time around the great sun. In a few billion years, it could collide with the Earth.
Traction of space around the rotating bodies: The rotation of a heavy object, such as the Earth, must rotate and disrupt the space of the surrounding space. In 2004, NASA launched the Gravity Probe B (GP-B). A well-balanced satellite made the axes of gyroscopes inside slow down over time, a result was consistent with Einstein's view.
"Imagine the Earth as if it were drenched in honey," Gravity Probe-B chief investigator Francis Everitt, of Stanford University, said in a statement.

"As the planet orbits, the honeycomb around it could orbit over time, and it is the same from time to time. GP-B has confirmed two very important predictions of Einstein's universe, which have had a profound impact on astrophysics research."
Gravitational redshift: The electromagnetic radiation of an object is slightly extended within the field of gravitational force. Think of the waves crashing from the head of an emergency vehicle; when the car is moving in the viewer, the sound waves are compressed, but as they move, they are stretched, or reversed. Known as the Doppler Effect, similar events occur with light waves in all waves. In 1959, two scientists, Robert Pound and Glen Rebka fired radiant gamma rays across the side of the tower at Harvard University and found that they were much smaller than their natural frequency due to distortion caused by gravity.


Applications of relativity
Rather than just being a theoretical interest, relativistic results are essential to practical engineering concerns. Satellite-based measurement needs to take into account the associated effects, as each satellite travels under the user bound to Earth and therefore a different structure than the relativity view. Global positioning systems such as GPS, GLONASS, and Galileo, must respond to all related effects, such as the effects of the Earth's gravitational field, to operate accurately. This is also a measure of the accuracy of time. Tools ranging from electron microscopes to particle accelerators would not work if related considerations were omitted.


Electromagnets
Magnetism is a dynamic force, and when you use electricity you can appreciate the connection that generators work at all.
What is the theory of relativity? Relativity explained briefly.
When you take a wire loop and move it with a magnetic field, it generates electrical energy. The charged particles in a wire are affected by a dynamic magnetic field, forcing some of them to move and build up.
But now, think of the phone and relax and imagine that the magnet is moving. In this case, the charged particles in the wire (electrons and protons) no longer move, so the magnetic field should not touch them. But it is possible, and it is still happening. This indicates that no index is valid.


Global Positioning System
For your car's navigation to be as accurate as it is, satellites must take into account the consequences of compliance. This is because although the satellites do not move at anything that approaches the speed of light, they are still moving very fast. Satellites also send signals to Earth's Earth stations. These channels (and the GPS unit in your car) are all subject to high speeds due to gravity than satellite satellites.
What is the theory of relativity? Relativity explained briefly.

To achieve that precise accuracy, satellites use precision clocks in a few billion seconds (nanoseconds). Since each satellite is 12,600 kilometers (20,300 kilometers) above the Earth and travels about 6,000 miles per hour (10,000 km / h), there is a corresponding time reduction that carries about 4 microseconds each day. Apply to the gravitational effects and the number rises to about 7 microseconds. That is 7,000 nanoseconds.
The difference is quite real: if there are no conciliatory results, the GPS unit telling you that it is five miles (0.8 km) to the next gas station can be 5 miles away after just one day.


Conclusion
Albert Einstein's theory of relativism is famous for speculating on some of the most unusual but realistic objects, such as the slightly older astronauts on Earth and solid objects that alter their formation at high speed. What do you think relativity can do more in the field of physics.
