Why Einstein said gravity is not a force?

Einstein said gravity isn't a force but the curvature of spacetime caused by mass and energy, meaning objects follow the straightest possible path (geodesic) in this warped geometry, which we experience as gravitational attraction. He proposed this in his General Theory of Relativity (1915/1916) to explain how massive bodies distort the universe's fabric, causing other objects (like planets or light) to move along those curves, unlike Newton's idea of gravity as an instantaneous force between masses.

Did Einstein say gravity is not a force?

Yes, Albert Einstein said gravity is not a traditional force, but rather a result of massive objects warping the fabric of spacetime; objects follow these curves, creating the appearance of a force, which is a core idea of his General Theory of Relativity. Instead of a mysterious pull (Newton's view), Einstein described it as geometry: mass tells spacetime how to curve, and curved spacetime tells mass how to move. 

Why is gravity not considered a force?

Gravity isn't a force in the traditional sense (like magnetism) but is described by Einstein's General Relativity as the curvature of spacetime caused by mass and energy; objects simply follow the straightest possible paths (geodesics) through this curved geometry, making it seem like they're being pulled by a force when they're just moving along the "dents" in spacetime, as if rolling down a curved surface.
 

What is Einstein's theory about gravity?

The theory of relativity comprises two physics theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. Special relativity applies to all physical phenomena in the absence of gravity.

How did Albert Einstein describe gravity?

Albert Einstein described gravity not as a force, but as a curvature or warping of spacetime caused by mass and energy; massive objects create dips in this fabric, and other objects follow these curves, creating the effect we perceive as gravity, like a marble rolling toward a bowling ball on a trampoline. His theory, General Relativity, posits that "matter tells spacetime how to curve, and curved spacetime tells matter how to move".
 

Discovery That Changed Physics! Gravity is NOT a Force!

Is Einstein's theory of gravity correct?

Einstein's theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own failure at spacetime singularities inside black holes — and the Big Bang itself.

What does the Bible say about gravity?

The Bible doesn't mention "gravity" as a scientific force but describes God as the one who upholds and holds all things together, implying His direct control over natural laws like gravity, with verses like Colossians 1:17 ("in him all things hold together") and Hebrews 1:3 ("upholds the universe by the word of his power") being key references for this concept of divine sustaining power, not a physical force description. It also notes Jesus' control over natural laws (walking on water) as a demonstration of superior power and uses the word "gravity" in the sense of seriousness or dignity (Titus 2:7).
 

What is the 3 law of Einstein?

The document then lists Einstein's three laws: 1) Objects remain in motion or at rest unless acted upon by an outside force, known as inertia. 2) Force equals mass times acceleration. 3) For every action there is an equal and opposite reaction.

Can physicists explain gravity?

And that's important, because while most of us know about Newton and the apple, gravity remains the great cosmic mystery. Although it was the first force to be described mathematically (by Isaac Newton in 1687), we still do not know how it really works – the best modern description is the general theory of relativity.

What were Einstein's last words?

Albert Einstein's last words are unknown because he spoke them in German to a nurse who didn't understand the language, so they were never recorded. Before his death in 1955, he had refused surgery, stating, "I want to go when I want. It is tasteless to prolong life artificially". While the precise words are lost, his final moments reflected his known scientific curiosity and philosophical outlook. 

How to prove gravity is a force?

Proof of gravitational force comes from everyday observations (things fall), astronomical phenomena (planetary orbits, tides), and precise experiments like the Cavendish experiment (measuring attraction between small masses) and missions like Gravity Probe B (measuring spacetime curvature), all confirming Newton's law and Einstein's General Relativity, showing gravity as a fundamental force between all masses.
 

What is 7G force?

"7 G's would be 7x the force of gravity," Stewart said. For perspective, people on earth feel one "G" on a daily basis. Experiencing the force of gravity at that high of a level causes some people to feel nauseous or dizzy, get tunnel vision and ultimately pass out.

Can humans survive 2 times gravity?

Our graph up there shows that humans can easily deal with 2 gs for a matter of minutes, but in the long term, if the body doesn't adjust, you may see some serious problems such as loss of consciousness and hypoxia in the brain and upper tissues, as well as swelling and bruising in the feet and legs.

Why is gravity not a force?

Gravity isn't a force in the traditional sense (like magnetism) but rather the effect of mass and energy curving spacetime, with objects following these curves, making it seem like a pull; this view from Einstein's General Relativity explains why objects, even light, follow curved paths, revealing gravity as a property of spacetime geometry, not a mysterious force between masses. When you're falling freely, you're just following a straight path (a geodesic) in curved spacetime, experiencing weightlessness until something (like the ground) stops your natural motion, creating the sensation of a force. 

What did Stephen Hawking say about Einstein?

Einstein had the ability to look beyond the surface to reveal the underlying structure. He was undaunted by common sense, the idea that things must be the way they seemed. He had the courage to pursue ideas that seemed absurd to others. And this set him free to be ingenious, a genius of his time and every other.

What is Einstein's biggest theory?

Our modern understanding of gravity comes from Albert Einstein's theory of general relativity, which stands as one of the best-tested theories in science.

Did Einstein say gravity isn't a force?

Yes, Albert Einstein said gravity is not a traditional force, but rather a result of massive objects warping the fabric of spacetime; objects follow these curves, creating the appearance of a force, which is a core idea of his General Theory of Relativity. Instead of a mysterious pull (Newton's view), Einstein described it as geometry: mass tells spacetime how to curve, and curved spacetime tells mass how to move. 

Why is 95% of the universe invisible?

Surprisingly, normal matter turns out to be only a small fraction of what the Universe contains. 95% of the Universe is made up of dark matter and dark energy. These are words astronomers have come up with to give a name to the mysterious, invisible side of the Universe.

Is gravity a fact or theory?

Gravity is both a fact (the phenomenon of objects attracting each other) and a theory (our best explanation for how it works, like Einstein's Relativity), with the theory being a highly verified model, not just a guess, that explains the observable facts of gravitational attraction and predicts phenomena. In science, a theory isn't uncertain; it's a robust explanation supported by overwhelming evidence, while a "law" describes what happens (e.g., F=macap F equals m a𝐹=𝑚𝑎), and a theory explains why (e.g., spacetime curvature). 

Did Newton believe in God?

Yes, Isaac Newton was a deeply devout Christian who believed in God, viewing his scientific work as a way to understand God's creation, but he held unorthodox, Arian-like views (rejecting the Trinity) and kept his intense theological studies private to avoid conflict with the Church. He saw God as the active, powerful creator and sustainer of the universe, a "masterful creator" whose existence was evident in the natural world's order and beauty, integrating his faith into his science and alchemy.
 

What is the rule of 7 Einstein?

Rule #5: Don't let politics fill you with either rage or despair. Rule #6: Blind obedience to authority is the greatest enemy of the truth. Rule #7: Science, truth, and education are for everyone, not just the privileged few.

What was Einstein's famous law?

Einstein provided the answer with his famous equation, E = m c2. In the equation, E = m c2, E stands for energy, m stands for an object's mass, and c2 represents the speed of light ( 186,000 miles per second ) multiplied by itself.

Why is 1 hour 7 years in space?

The statement that one hour in space is equivalent to 7 years on Earth is not accurate. Time dilation, a concept from Einstein's theory of relativity, does affect time in space relative to different reference frames, but the effect is typically negligible for most space travel scenarios within our solar system.

Is gravity created by God?

Whether God created gravity is a question that bridges faith and science, with many scientists (like Newton) seeing it as a divine law, while modern physics describes it through mathematical theories (General Relativity) and potential particles (gravitons), with no direct evidence of a creator, but believers often view these natural laws as expressions of God's design.
 

Does gravity make you age faster or slower?

"Gravity makes us age slower, in a relative term," Chou said. "Compared to someone not near any massive object, we are aging more slowly by a very tiny amount. In fact, for that someone, the whole world around us evolves more slowly under the effect of gravity." Related: What is the shape of the universe?
