8 ways to check Einstein’s theory of relativity

It was Albert Einstein’s theory of relativity One of the greatest advances in science Recently, since then changed the understanding of time and space.

This theory suggests that time and space are not absolute, but depend on speed and gravity. In addition, explain the movement of the planets around the sun.

Over the years this has been confirmed by a variety of experiments, including observing the deflection of light in the presence of mass and measuring the shift in the spectrum of light emitted by moving objects. But it is not necessary to carry out complex experiments for the sake of it, this is the most everyday way by which the theory is confirmed.

GPS

In order for your car’s GPS to take you where you want to go, the satellites must take into account the effects of relativity. This is because even though satellites are not moving near the speed of light, they are traveling very quickly.

And so, the satellites Send signals to ground stations Which experience accelerations due to gravity greater than those of the satellites in its orbit.

To achieve that precision that GPS needs, satellites have clocks that are accurate to a few nanoseconds. Each satellite is located 20,300 kilometers from Earth and is moving at about 10,000 kilometers per hour. That’s why I know It produces a relative time dilation that adds about 4 microseconds every day.

Taking into account the effect of gravity, the time dilation effect amounts to about 7 microseconds.

So if these effects are not taken into account, GPS Bugs can accumulate several kilometers throughout the day.

old televisions

Do you remember Tube TV? All old TVs were like this and tube screens cathode rays.

A cathode ray tube is a technology that works by shooting electrons at a phosphor surface with a large magnet. Each electron forms a pixel It lights up when it hits the back of the screen. In turn, electrons are released to move the image.

In these TVs, the effect of the theory of relativity is noticeable which is why manufacturers have had to take these effects into account when incorporating magnets.

Gold is yellow

Did you know that most metals are shiny because the electrons in the atoms jump from different energy levels? Some of the photons that fall on the mineral are absorbed, however most of the visible light is reflected and made to glow.

In the case of gold, it is a heavy element, so the inner electrons move so fast that the increase in mass and contraction in length is significant. This causes the electrons to orbit the nucleus in shorter paths and with greater momentum.

Electrons in the inner region have a different energy than the outer electrons, f The wavelengths it absorbs and reflects are longer. This means that some of the visible light that would normally be reflected is absorbed.

Notably, this light is on the blue end of the spectrum, so in gold, because the wavelengths tend to be longer, the mix of light waves you see tends to be less blue and violet. The wavelengths of yellow, orange and red light are longer They are the offenders of this yellowish color gold.

Gold fell to its lowest in two years on fear of a US interest rate hike

Gold’s resistance to corrosion

This previously described effect also prevents the kiln from corroding. The electrons in this metal are very heavy and move very quickly, therefore It is difficult for her to interact with other metals.

By its very nature, it is unlikely to be the outermost electron as it can interact with anything at all; It is likely to be among the electrons close to the nucleus.

Mercury is liquid

Mercury is a heavy atom, so its electrons stay close to the nucleus due to their increased speed and mass as is the case with gold.

This makes the bonds between the mercury atoms weak and thus the metal It melts at lower temperatures and is often seen in a liquid state.

the light

Newton Suppose there is a frame of absolute comfort against which all other frames of reference can be compared. If so, there would be no light.

Neither does magnetism, because relativity requires that changes in the electromagnetic field move at a finite speed. However, if relativism does not impose these conditions Changes in electric fields will not be through electromagnetic waves And there will be no magnetism or light.

sun

Without an explanation of the E = MC2 equation, the Sun and the rest of the stars would not shine. That’s because it’s in the sun Very high temperatures and pressures It is constantly compressing four hydrogen atoms into one helium atom.

The mass of one helium atom is slightly less than four hydrogen atoms, so the excess mass is converted into energy, which manifests itself in the form of sunlight.

Electromagnet

Magnetism can be easily shown using generators. It only takes a coil of wire to figure out how, Moving it through a magnetic field generates an electric current. The charged particles of the wire undergo changes in the magnetic field, which moves them and creates a current.

But if the wire is at rest and the magnet is moving, the charged particles in the coil (electrons and protons) are at rest and One might think that the magnetic field does not affect them. However, it does, and the current continues to flow.

The theory of relativity predicts that gravity is not a mysterious force that pulls objects toward other massive objects, but rather is a consequence of how an object’s mass warps space-time around it.

Around 1910, a German physicist named Gustav Mey proposed an alternative theory of gravity, which was based on the idea that gravity was an electromagnetic force. This theory was widely accepted at the time, but was eventually found to be incorrect..

One way the theory of relativity has been confirmed is through experiments involving electromagnets. Electromagnets are devices that use electric current to create magnetic fields.

When a magnet or electromagnet moves, an electric current is generated, which in turn produces an additional magnetic field. This phenomenon is known as electromagnetic induction.

In this sense, an examination, known as the Havell-Keating experiment, was carried out using Atomic clocks Very accurate they were sent on planes that circled the Earth in opposite directions.

According to the theory of relativity, the time should be slightly different every hour due to the curvature of space-time around the Earth. Experience confirmed this Atomic clocks on airplanes have seen little change in timeAs predicted by the theory of relativity.

In short, it is not that electromagnets directly confirm the theory of relativity, but that it has been used in experiments such as Havel-Keating to show that the theory is correct in predicting changes in time perception under different conditions of gravity.
