This eclipse proved Einstein right.

29 May 1919It is the day of the solar eclipse that caused the scientific revolution. The eclipse is famous for testing Albert Einstein’s Theory of General Relativity. Einstein was not known at the time. He proposed the general theory of relativity in 1915, and scientists were amazed by all new ways of thinking about gravity – for example, the idea that mass curves space – but no one has. Experiment Proved that the theory is correct Then, on May 29, 1919, a team of British scientists led by Sir Arthur Eddington traveled to Principe Island, off the western coast of Africa, to observe the total solar eclipse. If the theory is correct, then the light from the stars should be. Bend By the gravity of the sun and appears to be moved An eclipse that the moon obscures enough sunlight to see the stars near the sun is a great opportunity to test this out.

Scientists’ measurements during the eclipse showed that Einstein’s predictions were surprisingly accurate. The positions of the stars that are now visible appear to be moved as their light travels to us in space, curving around the sun, caused by gravity, as Einstein described.

From anonymity to stardom through eclipses

Later that year – November 6, 1919 in London – British astronomer Frank Dyson, who was managing the expedition, presented the results of a joint meeting of the Royal Astronomical Society and the Royal Society, Dyson said. It said “no doubt” that the measurements taken during 29 May 1919 the eclipse “confirmed Einstein’s prediction”.

As part of this legendary solar eclipse’s 100th anniversary celebration, Caltech physicist Sean Carroll explained to NBCNews in 2019:

General relativity is the poster boy, as it is a crazy and elusive new theory with a huge impact on the nature of reality. But you still see [the results]; You can take pictures. So people were caught up in the excitement.

Thus, Albert Einstein gained a rock star reputation, a state in popular culture that he has maintained ever since.

During a solar eclipse, stars normally not visible in bright sunlight, they appear on the sides of the sun and are moved away from their normal position.Why? Because – just as Einstein’s theory states that should – light will bend in front of the mass, in this case the mass of our solar star. Instead of traveling in a straight way, the light of distant stars is forced to travel in a curved path along a curved space near the Sun. Please note that this photo contains too much starlight curl. In fact, these stars are transported by as much as 1.75 arc seconds (approximately 0.0005 degrees) .Image via GSFC / NASA / DiscoverMagazine.com.

New perspectives on gravity and the universe

Einstein’s theory of general relativity is the most fundamental of modern cosmology, a way of looking at the universe as a whole. Before Einstein, scientists relied on Isaac Newton’s theory of gravity. Newton’s method of viewing gravity is still valid and is still taught to physics students. But while Newton’s determination of gravity is a special case under specific conditions, Einstein’s theory refines scientists’ understanding of gravity that encompasses the big picture … and. It’s an incredible overview! Einstein proposed that mass curves space. For example, though there is a “force” (Newton described) that causes our Earth to be drawn towards the Sun by gravity. But that force can be described “simply” as a world traveling in space, curving around the sun. According to Einstein

Einstein’s theory of general relativity is not only It only describes the motion of Earth and other planets in our solar system. Our modern cosmology also describes extreme examples of curved space, such as surrounding a black hole. And helps explain the history and expansion of the universe as a whole.

A solar eclipse is the first evidence of many.

In the centuries that have passed since the eclipse of the year 1919 Einstein’s theory of relativity has been proved time and again in many different ways. You may have seen your first photograph of a black hole recently? It also proved once again that Einstein was right.

Now and after

The Royal Astronomical Society (RAS) has described the current application of Einstein’s theory:

Fundamentally, this theory has changed our understanding of physics and astronomy and supports important modern technologies such as satellite-based global positioning systems (GPS).

The theory of relativity is essential for the correct operation of GPS systems, which, in turn, relies on many common applications, including Vehicle Satellite Navigation (SatNav) forecasting. Weather and disaster relief and emergency services However, the world had to wait decades before it was able to recognize the use of such a blue sky.

Back on the day of the 1919 eclipse, Sir Arthur Eddington attended the same corporate dinner – RAS shortly after the expedition was successful. He then showed his humorous side by reciting a poem he wrote in success:

Let go of our smart measures to check.
At least one thing is for sure: light has weight.
One thing is certain and the discussion is left.
Light near the sun, do not go straight

Bottom Line: A May 29, 1919 solar eclipse is the date astronomer Sir Arthur Eddington reviewed Einstein’s theory of general relativity, noting that the near-star of the star was. How was the sun moved from its normal position? This noticeable change in position occurs because, according to Einstein’s theory, the path of light bends according to gravity as it approaches large objects such as our sun.
