Could it be possible that space-time curvature is not caused by matter but is an inherent characteristic of space-time? Wouldn't this explain dark matter?
Grieverheart said:Yes but a cosmological constant in a sense gives a global curvature not a local one.
Grieverheart said:Yes, my thought is that maybe matter is not what curves space-time (i.e. it is not matter that attracts matter) but a curvature already existed in place beforehand.
Space-time curvature refers to the bending of space and time in the presence of massive objects such as planets, stars, and galaxies. This concept is a fundamental part of Einstein's theory of general relativity.
The theory of dark matter suggests that there is a significant amount of matter in the universe that cannot be directly observed because it does not emit or interact with light. Space-time curvature can explain the effects of this invisible matter on the motion of visible objects, such as stars and galaxies, through its gravitational pull.
Previous theories about dark matter proposed the existence of undiscovered particles that make up the invisible matter. This new perspective suggests that the effects attributed to dark matter can be explained by the bending of space-time in the presence of massive objects, without the need for new particles.
Observations of the rotation of galaxies, the distribution of matter in galaxy clusters, and the bending of light by massive objects all support the existence of dark matter. However, recent studies have shown that these phenomena can also be explained by space-time curvature without the need for dark matter particles.
If space-time curvature is confirmed as the primary explanation for dark matter, it could revolutionize our understanding of the universe. It would mean that we do not need to rely on the existence of new particles to explain the behavior of objects in space, and it could lead to new insights into the nature of gravity and the structure of the universe.
