What is behind space-time?

In physics, spacetime is any mathematical model which fuses the three dimensions of space and the one dimension of time into a single four-dimensional manifold. The physicist Albert Einstein helped develop the idea of spacetime as part of his theory of relativity.

Where does time go slower in space?

Public Domain The phenomenon is called “gravitational time dilation.” In a nutshell it just means time moves slower as gravity increases. That’s why time passes slower for objects closer to the center of the Earth where the gravity is stronger.

Can time be changed?

Time is the one thing that’s impossible NOT to change (unless you’re a light beam). Your speed relative to light, and proximity to mass will also affect how time flows for you. There is no absolute or standard “time”, only the flow.

Can we see space-time up close?

Researchers at the European Space Agency have proposed the Gamma-ray Astronomy International Laboratory for Quantum Exploration of Space-Time (GrailQuest) mission, which would fly around our planet and make ultra-accurate measurements of distant, powerful explosions called gamma-ray bursts that could reveal the up-close nature of space-time.

Does time slow down as you travel through space?

Well, according to this theory, the faster you travel, the slower you experience time. Scientists have done some experiments to show that this is true. For example, there was an experiment that used two clocks set to the exact same time. One clock stayed on Earth, while the other flew in an airplane (going in the same direction Earth rotates).

How big is the discreteness of space?

By the time I started doing physics in the 1970s, nobody really talked about discreteness of space anymore, and it was experimentally known that there wasn’t discreteness down to about 10 -18 meters (1/1000 the radius of a proton, or 1 attometer ).

What is the theory of space-time?

According to the best of current physical theories, space-time explains the unusual relativistic effects that arise from traveling near the speed of light as well as the motion of massive objects in the universe. Who discovered space-time?
