Einstein has proven itself even in other galaxies

The name of Albert Einstein is synonymous with intelligence, but he is more than deserved his representative. The man revolutionized physics when he was in his twenties and thirties. He came with a whole new way of understanding reality, not as a fixed grid against which events occur, but as fundamentally intertwined with time and perception. Trying to prove that Einstein is wrong, in a way, is an eternal goal of aspiring and experienced physicists.

Well, they will have to keep trying. A new study from Science shows today that Einstein was so good, even in distant galaxies that he is always right.

Warp Zone

All of this is related to general relativity, Einstein. s theory of gravity, which postulates that everything that has a mbad deforms the fabric of space-time. The larger the mbad, the more the universe is deformed around it. This explains why mbadive objects attract less mbadive objects: they only follow the curves of space-time. Light also follows the chains and frames created by gravity – black holes and galaxies literally bend the light around them. Sometimes, when fairly mbadive objects just align, they can actually focus the light further away like a glbad lens. telescope, with the turns in the space-time acting as a kind of "gravitational lens."

And while these are useful in studying these ultra-distant objects emitting this deformed light, they can also serve as a "laboratory"

Relatively Simple

C & # 39; is important because even though scientists have confirmed Einstein's general relativity within the solar system, they are still small potatoes compared to the larger universe. As the authors of the document write, "the long-range nature of gravity is still poorly limited." So they found a way to use a gravitational lens near the galaxy ESO 325-GOO4 to test galactic-scale relativity

First, the team measured how much the galaxy was distorting space-time, using Hubble data from the region. This allowed them to derive the mbad of the galaxy. Then they calculated the mbad in a different way, observing the stellar motion, this time using data from the Very Large Telescope in Chile. If Einstein was right, the two characters should be pretty much the same.

Spoiler alert: Einstein was right. The ratio between the two values ​​was 0.97 ± 0.09, which is very close to the predicted value of 1.

This is great news not just for Einstein's worshipers, but also for those who want to understand what is happening in the large-scale universe. The discovery excludes many alternative theories of gravity, and confirms that even on a large scale, general relativity is true. It also means that we must keep around the notion of dark energy – the still mysterious force propelling the universe to grow faster and faster – since it is (in part) a consequence of general relativity.
