He sees through the complexities of space-time curvature
, understanding that the shortest distance between two points is a straight line only from the perspective of the moving object.
The idea that we could see the same object by looking in opposite directions on the sky is a recurrent theme in cosmology, ever since Albert Einstein first described space-time curvature
100 years ago (S&T: Dec.
Mirrors with kilogram masses have a proper gravitational field and cause a space-time curvature
in their vicinity.
Thoughts of science as sometimes embodied in almost mystical expressions like "undimensional singularity", "uncertainty principle", "Thermodynamical equilibrium" - which is but death of the system - 'Quantum spin', 'Schrodinger's cat', infinite density in space-time curvature
The descendants of neo-Kantianism assert that space-time curvature
caused by matter and energy is impossible, since matter and energy already require the concepts of space and time.
The nature of the "singularity" inside a black hole--the region where the space-time curvature
becomes infinitely sharp--nevertheless inspires active theoretical research.
In Einstein theory, which equates space-time curvature
to Gravitation, the propagation velocity has no meaning.
If this latter is reasonably due to the dynamics of our universe and if the kind of this dynamics determines itself both space-time curvature
and sign of [+ or -] [mu], has this sign to do with the fact that our universe is preferentially made of matter rather than of antimatter?
Einstein's theory of gravity where gravitational forces are theorized to arise from space-time curvature
One possible geometry that complies with such a space-time symmetry is the geometry of distant parallelism with vanishing space-time curvature
(but non-vanishing Riemann-Christoffel curvature) and non-vanishing twist.
13) It is important to note that the expected gravitational waves are waves of the space-time curvature
, not merely of the spatial curvature of the threedimensional space.
As it is known, waves of the metric are linked to the space-time curvature
derived from the Riemann-Christoffel curvature tensor.
