Discovery That Changed Physics! Gravity is NOT a Force!

Discovery That Changed Physics! Gravity is NOT a Force!

Gravity is one of the four fundamental forces of nature in the Universe. But of the four forces of nature, it stands alone as different. In fact, gravity isn’t the force you think it is, and perhaps it's not a force at all.

If you think you understand gravity, then get ready to change the way you think about gravity…forever.

All I know is that time and space are relative...the more time I spend with my relatives the more space I need

Who else was watching closely in hopes the astronaut would drop the hammer and feather?! 😭

As a 90s kid from India i wished we had Internet and Smartphone while i was a kid, i could've learnt much more that what school offers through YT

This is the first time I followed an explanation of this. It is so different than the conventional perception of the force of a gravity field. Excellent work.

[El-Rico]

Newton's Principia: 1687; Einstein Theory of Special relativity: 1905. In this space-time continuum, those are not 400 years apart but 218 years...

[RafaelBenedicto]

What are you talking about? This isn't a "new discovery", it's been realized that gravity isn't a force ever since Einstein published General Relativity.

In the future kids will be learning about gravity and they’ll look at us the same way as we look at those who thought the planet was a square or just flat

[averagejoe]

Einstein's paper "On the Electrodynamics of Moving Bodies" (aka Special Relativity) was published in 1905. His paper on General Relativity was published in 1915-1916.

Ross: You uh, you don't believe in gravity?
Phoebe: I don't know, lately I get the feeling that I'm not so much being pulled down as I am being pushed.

[duck-fil-a]

The explanation just given for gravity is circular reasoning. The narrator basically said gravity works by a warping of spacetime creating a gravity well, pulling objects down into the well. But what is pulling the objects down into the gravity well? Gravity? If so then that hasn’t answered the question of how does gravity work, you’ve simply stated that gravity works by a warping of spacetime pulling objects into a gravity well by gravity. In other words, just like Newton asked why the Apple fell down instead of sideways or upwards, or fell at all, the same question is still left, why did the object fall into the gravity well instead of away from the well or not at all.

That's not a discovery but a hypothesis. That's a massive difference

[jaidamwhi]

Its funny to think that absolutely no one else is recognized for the "discovery" of gravity like no one before him (or even him for that matter) never seen something fall or dropped something

[honved_]

First the Big Bang never happened. Then the immortal Queen dies. Now the force of gravity is not a force. This month is pretty crazy.

[kennedychidi]

Physicist: Sorry Newtown we're now using special theory of relativity.
NASA: Sorry Einstein we're still using gravitational laws.

I learned the “stretched rubber flat plane” thing many years ago and it blew my mind. It made so much sense and was so simple

[davidlarson]

You've got an error in the video. At 7:46, you say that the acceleration of gravity is 9.81 meters per second. Meters per second is a unit of speed, not acceleration. Acceleration is the *change* in speed over time. So, the acceleration of gravity (called capital G in physics) is actually 9.81 meters per second *squared*.

“You underestimate the power of the dark side of the force.”

[nojukuramu]

i like how the explanations really explains what gravity is but doesnt actually make it for us to easily understand because of the terminologies 😂

[AlwyneAvinash]

It becomes more interesting when the fabric of spacetime is visualized in 3D, in this video it's been visualized in 2D

I am still exploring the space between my ears. My wife’s theory predicts that a feather and a hammer will fall at the same speed from one ear to the other when I am on my side and she is keen to try the experiment out.
