Keep us firmly grounded.We call it gravity.(If your brain hurts, don't worry, here's an article dedicated to destroying this concept.)And while the genius mathematician referred to this puzzling idea as his theory of general relativity, a title that stuck, colleagues called it "completely impractical and ridiculous," a title that was not.Against all odds, Einstein's paralyzing idea has not yet wavered.His buildings remain true on both a smaller and inexplicably large scale.Experts have tried to make holes repeatedly And the repeatedly And the repeatedly, but general relativity always prevails.And on Wednesday, thanks to an ambitious satellite experiment, scientists announced, once again, that general relativity has turned out to be a fundamental fact of our universe.The team performed what they called the "most accurate test" of one of the key aspects of general relativity, called the weak equivalence principle, with a task called a microscope."I have been working on this topic for more than 20 years and I realized that I had the opportunity to be the project manager of the scientific instrument and the co-investigator for this mission," said Manuel Rodriguez, a scientist at the French space laboratory. .ONERA and author of a new study, published in physical review letters."It is very rare that such an extraordinary result is left in the history of physics."A representation of how Einstein's relativity imagined the universe.The Weak Equivalence Principle It is strange.It basically says that all objects in a gravitational field should fall the same way when no other force hits them - I'm talking about external interference like wind, someone kicking an object, another object hitting it, you hit yourself. 'idea.And yes, when I say all things, I mean all things.feather;piano;Basketball;you and me;Whatever you can imagine, in reality, according to this principle, it should fall exactly the same way.The microscope project sent a satellite into Earth orbit containing two objects: a platinum ingot and a titanium ingot.“The choice was based on technical considerations,” for example whether the materials were easy and feasible to make in the laboratory, Rodrigues said.But above all to understand the Weak Equivalence Principle, or WEP, this alloy has exploded in Earth's orbit because the material is present in our planet's gravitational field with no other forces affecting it.Perfect for standards testing.Once the satellite reached space, the researchers began testing, for years whether they are immersed platinum tips or titanium tips in the same way while they were in orbit around the earth.They did it - to a very precise degree.“The most exciting part during the project was developing a tool and a task that no one had ever done with this level of precision before - a new world to explore,” said Rodriguez."As pioneers of this new world, we expected every moment to encounter phenomena we had never seen before because we were the first to enter".Capsule used during a microscope mission.If you are interested in the technical aspects, the results of the experiment showed that the acceleration of fall of one alloy differs from the other by no more than 1 part in 10 ^ 15. Researchers say that a difference beyond this amount means a violation of WEP from our current understanding of Einstein's theory.Going forward, the team is working on a follow-up mission called Microscope 2, which Rodrigues says will test the weak equivalence principle 100 times better.However, this may be as good as it will be for at least a decade or so, the researchers say.In a sense, the rigidity of general relativity is somehow a problem.This is because, although it is a basic blueprint for understanding our universe, it is not Just Schema.We also have constructs like the Standard Model of particle physics, which explains how things like atoms and bosons work, and quantum mechanics, which explains things like electromagnetism and the uncertainty of existence.Both concepts seem indissoluble like general relativity, but they are incompatible with it.So… there must be something wrong.And this thing prevents us from creating a unified history of the physical universe.The Standard Module For example, Famous can't explain gravity and general relativity Don't really look at quantum phenomena.It is a great battle to be the ultimate theory.Standing microscope team with satellite equipment, right."Some theories involve a coupling between gravity and some electromagnetic parameters," Rodriguez provided as an example."This coupling does not exist in Einstein's theory, which is why there is WEP."We are at a crossroads.But the bright side is that the vast majority of scholars consider all of these theories incomplete.So, if we can somehow find a way to end them - they spot a new pairing, for example, says Rodrigues, or they select a new particle to add to the Standard Model - that could lead us to the missing pieces of the puzzle of our universe."It should be a revolution in physics," Rodriguez said of the WEP breach."It would mean that we have found a new force, or perhaps a new particle like the graviton: it is the trophy in the world of physics.""Player.Aspiring beer evangelist.Pop culture professional.Travel lover.Social media supporter.
