Einstein's Space-Time and "Ripples in Reality

In summary, there is a suggestion that light can be explained as moving magnetic fields in the "fabric" of space, which may also be slight waves. This idea has been combined with quantum mechanics to attempt to describe the universe, using up to 11 dimensions. However, the ability of electromagnetic radiation to transmit energy without a medium remains a question, with the possibility that the electrostatic force of electrons is a combination of repulsion and momentum.

If, according to Einstein, that space-time is a "fabric", could there be waves in this "fabric"?

thanks man.

I also wonder if light can't be explained as moving magnetic fields, which themselves may be slight waves in the "fabric."

Moving electric and magnetic fields both. It's not thought that the electromagnetic fields are ripples in the fabric of space but actually there are suggestions that this could be the case.

The most tantalizing such suggestion is this: if you work through Einstein's equations for ripples in the fabric of space but you use 5 dimensions instead of 4, the equations that descrlighthearted movement of light also appear.

This kind of thinking has been carried forward over the century and joined with another great theory in physics called quantum mechanics to produce the best attempts we have to describe the universe. The number of dimensions has gone up from 4 to 10 or 11, so your intuition is good.

Blast autocompletion and the iPhone app on this site.

Descrlighthearted should read "describe the movement of" but I can't edit the post because the window won't scroll down.

Magnetic fields do not require a medium, so they are the best candidate, imo, for explaining the ability of electromagnetic radiation to transmit energy without a medium. What I want to figure out is how the electrostatic force of electrons occurs. Is it a combination of the repulsion of negative-negative electron charges and their momentum or something else completely?
 

What is Einstein's theory of space-time?

Einstein's theory of space-time, also known as the theory of general relativity, states that space and time are not separate entities, but are interconnected and form a four-dimensional fabric known as space-time. This theory explains the force of gravity as the curvature of space-time caused by massive objects.

How did Einstein come up with the theory of space-time?

Einstein developed the theory of space-time through years of thought experiments and mathematical equations. He was inspired by the work of physicists such as Isaac Newton and James Clerk Maxwell, and his theory was also influenced by his belief in the principle of relativity, which states that the laws of physics are the same for all observers in uniform motion.

What are "ripples in reality"?

"Ripples in reality" refer to gravitational waves, which are disturbances in the fabric of space-time caused by the acceleration of massive objects. These ripples were predicted by Einstein's theory of general relativity and were first observed in 2015 by the Laser Interferometer Gravitational-Wave Observatory (LIGO).

How do "ripples in reality" affect us?

Gravitational waves have a very small effect on our everyday lives and are only noticeable when they come from extremely massive objects, such as black holes or neutron stars. However, studying these ripples can provide valuable information about the nature of the universe and help us understand some of the most mysterious phenomena in space.

What implications does Einstein's theory of space-time have for our understanding of the universe?

Einstein's theory of space-time revolutionized our understanding of the universe and has been confirmed by numerous experiments and observations. It has led to advancements in fields such as cosmology and astrophysics and has helped us gain a deeper understanding of the fundamental laws of physics. It has also opened up new possibilities for space exploration and the study of the universe.
