The discussion revolves around the nature of gravity as described by Einstein, particularly how it applies to objects attracted to Earth. Participants explore the concept of gravity as the curvature of spacetime and how this differs from classical Newtonian views.
Participants generally agree on the idea that gravity is related to the curvature of spacetime, but there are differing interpretations of how this applies specifically to objects attached to Earth versus celestial bodies.
Some statements reflect a lack of clarity regarding the implications of spacetime curvature and its effects on objects in different contexts. There are also references to external resources for further reading, indicating that the discussion may not cover all necessary foundational concepts.
This discussion may be of interest to those exploring concepts in general relativity, students of physics, and individuals curious about the nature of gravity and its implications in different contexts.

So u mean to say that due to curvature made by Earth's mass, we r attracted towards Earth?? Or something else?Ibix said:Gravity is curvature of spacetime. That's true whether the source of gravity is a star or the Earth or you. The "strength" of curvature is different in each case, but the idea is the same.
Basically. Spacetime near anybody with mass doesn't obey the rules of Euclidean geometry. The notion of things moving in straight lines unless acted on by a force is replaced by things moving along curves (towards the Earth) unless acted on by a force - such as the floor pushing up on you. The videos that A.T. posted above are good illustrations.Shubham Raj22 said:So u mean to say that due to curvature made by Earth's mass, we r attracted towards Earth??
Just to offer input, Einstein thought of gravity as more of a "side-effect" of the curvature of space time, compared to Newton's view of gravity being an attraction of massive bodies.Shubham Raj22 said:So u mean to say that due to curvature made by Earth's mass, we r attracted towards Earth??
