What is the relationship between the presence of mass and the curvature of space time?
The distortion caused by each sphere is proportional to its mass. The curvature of spacetime influences the motion of massive bodies within it; in turn, as massive bodies move in spacetime, the curvature changes and the geometry of spacetime is in constant evolution.
Does mass create spacetime?
Earth’s mass warps space and time so that time actually runs slower the closer you are to earth’s surface. Although this is a very weak effect, the time difference can be measured on the scale of meters using atomic clocks.
What is the principal difference between the theory of special relativity and the theory of general relativity?
Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to other forces of nature. It applies to the cosmological and astrophysical realm, including astronomy.
What causes spacetime curvature?
Gravity is the curvature of spacetime Gravity is the curvature of the universe, caused by massive bodies, which determines the path that objects travel. That curvature is dynamical, moving as those objects move. In Einstein’s view of the world, gravity is the curvature of spacetime caused by massive objects.
What does spacetime tells matter how do you move matter tells spacetime how do you curve mean?
Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short description from the physicist John Wheeler hides a more complex and profound truth. Special relativity tells us motion warps space and time.
What causes space-time curvature?
What are the differences between the two theories of relativity?
The “General Theory of Relativity’ is related to gravity. The difference between the two theories is that the theory of general relativity throws light on the force of gravity with respect to curving four-dimensional space-time. As per Einstein, the accelerative and gravitational forces are equal and same.
How does the theory of general relativity compare to the theory of special relativity quizlet?
What is the principal difference between the theory of special relativity and the theory of general relativity? Special relativity applies to frames of reference moving at constant velocity, whereas general relativity includes accelerating reference frames.
Is time Travelling backwards possible?
As for backward time travel, it is possible to find solutions in general relativity that allow for it, such as a rotating black hole. Traveling to an arbitrary point in spacetime has very limited support in theoretical physics, and is usually connected only with quantum mechanics or wormholes.
Is spacetime curved by mass or volume?
Einstein demonstrated that spacetime is curved by masses, not by volumes. This assertion, which is verified by experimentation, is totally irrational since, to date, no one can explain how a mass can curve spacetime. So, the question is:
What is the relationship between mass/energy and gravity?
Mass curves spacetime, there is no such thing as gravity? It is said that there is no such thing as gravity. Mass/energy curves spacetime and a body follows this curvature so gravity is basically the geometry of spacetime.
How does spacetime affect the density of a closed volume?
The density of spacetime around the closed volume increases, and the latter has difficulty to move. As a result, a “mass effect” appears, i.e. an effect having all the characteristics of mass. Since spacetime has properties of elasticity (Einstein), it exerts a pressure on the surface of closed volumes.
Is gravity an attractive force between two masses?
Spacetime curvature, Gravity would not be an attractive force between masses but an external pressure force produced by the spacetime curvature. A rational explanation of many enigmas of physics is also given in that webpage: faster-than-light neutrinos, time dilatation, mass of relativistic particles, E = mc², black holes…
