Astronomy - General Relativity (5 of 17) Warping of Space Illustrated: Ggeometry

To donate:

We will learn The Equivalence Principle by learning about the geometry of warping of space illustrated that the angle of 3 observed stars in triangular configuration on a plane where the sum of the “triangle” does not equal to 180 degrees.

Actually Her questions r too much helpful . Please keep it up in every videos

Here are two shortened quotes of Newton R Bentley: (1) "...for the cause of gravity is what I do not pretend to know, and therefore would take more time to consider of it” and (2) “Gravity must be caused by an agent [acting] consta[ntl]y according to certain laws, but whether this agent be material or immaterial is a question I have left to the consideration of my readers.”
Just because Einstein failed to address the "cause of gravity" that does not allow you to ignore this glaring fault or weakness of mass-based gravitational theory as proposed by either Newton or Einstein. Unlike Newton or Einstein, you and I are the benefactor of the internet and YouTube and therefore have the tools to address this problem. And just because the "cause" is hiding in plain sight that is not give one an excuse to avoid realizing what that true, actual "cause" is. Peter Fred

Good question and very good explanation....

At the starting point of the curve, a tangent drawn will point towards the direction of light without the influence of the sun. This tangent will be more diverted from the sun than the curve. So gravity is actually pulling that light towards the mass(sun).

I think more curvature of space is made by the equator of the sun(because of more mass in the equator region). So light traveling will bend towards the equator. But the sun is almost a sphere. So space wrap is almost the same in all directions.
But that's not the case of Earth. Equator region creating more curvature. So everything is more attracted towards the equator. So that's why meteoroids are more likely to strike the equator.
What do you think about my assumption?

Maybe if you used as star with 16 'light beams' eminating from it for a couple of inches [equal all arounf the star] and then use one that would form the straight line [triangle] and use a 'beam' 2 further on that curves.
This might make it more visual. Edit: Congrats on 600k subs! You have grown a lot since I subscribed to you a couple of years or so ago! Well done!

"you have to use your imagination a little bit" LOL, love it.
thanks for the knowledge .

While new to physics, a phrase like "curves toward the sun" was ambiguous, so I mistook it to mean moving in a path of collision with the sun.

Is this correct: Curvature toward the sun is meant in an orbital sense. If the light from the stars were not curving toward the sun, it would be traveling in a straight line?

Hi Michel, there's a typo in the video title as well as in the description. "Ggeometry" in the title and "cVisit" at the top of the description

[armanrahman]

Then what about the other rules of light? As says Light takes the shortest path in which the time is least! If it curves its path then the time it travels gets longer...so the least time principle is invalid?(Fermat's law)

[armanrahman]

Why a+b+c cant be less than 180°? As the space just near the sun is deep, so it could happen than the light form star 🌟 3 goes down to sun then again goes aways from it up to 🌟 1
?

Which of these have more water molecule than another?
Ice density is 900kg/m^3 in -5 celsius, Steam density is 3.2kg/m^3.How to find the water molecule ratio of the two?.

[zakirhussain-jsku]

I consider Space to be another form of matter. Therefore I can understand warping of Space around a massive body. What about spacetime. How can we warp time.

Very interesting video...I would like to know the units in which curvature is expressed, as I read that through the field equations Einstein established that curvature (left hand side) was equivalent (caused due to) to distribution of energy(right hand side). So, are the units in metre, or something else??
The videos are very helpful...😀😀
