Can we bend the space/time continuum?

Can we bend the space/time continuum?

Spacetime, however, is the combined concepts of space and time into a four-dimensional continuum. You may have even seen spacetime portrayed as a fabric, manipulated by energy. If spacetime can be bent, Beacham continued, it’s theoretically possible that time can be bent.

What did Einstein mean by curved spacetime?

“It follows what space does, so if space curves, then light is going to curve,” Speck said. “When you take a particle which has mass and put it to spacetime, then the particle actually distorts the geometry of spacetime which becomes not flat but curved. And this is the curvature of spacetime,” Kopeikin said.

Did Einstein say space is curved?

Einstein said that space is curved and that matter is the source of the curvature. (Matter is also the source of gravitation, so gravity is related to the curvature—but that will come later in the chapter.)

What is curved spacetime called?

relativity – Curved space-time and geometric gravitation | Britannica.

Does gravity cause redshift?

Within Einstein’s general theory of relativity there is an effect known as “gravitational redshift,” in which light becomes redder because of the influence of gravity; the wavelength of a photon, or light particle, gets longer and appears redder as the wavelength climbs farther away from a gravitational well.

Is time the 4th Dimension?

According to Einstein , you need to describe where you are not only in three-dimensional space — length, width and height — but also in time. Time is the fourth dimension. So to know where you are, you have to know what time it is.

How does curved spacetime cause gravity?

Gravity is the curvature of spacetime It is here that Einstein connected the dots to suggest that gravity is the warping of space and time. 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.

What is the space-time continuum?

Something called a “space-time continuum” certainly sounds like it would be out of this world. In reality, though, it’s far from science fiction. It’s actually a theoretical scientific construct that could help explain the very fabric of our existence. The idea of a space-time continuum comes from the groundbreaking work of Albert Einstein.

What is the space-time curve?

Space-time curve often refers to a spatial geometry that is not “flat”, where a flat space is described by Euclidean geometry. Curved space plays an essential role in general relativity, where gravity is often viewed as curved space.

Should physicists use curved or flat spacetime techniques?

Working physicists routinely switch between using curved and flat spacetime techniques depending on the requirements of the problem. The flat spacetime paradigm turns out to be especially convenient when performing approximate calculations in weak fields.

What do the time and space components add up to?

The time components add up to total E/c of the resultant vector, meaning that energy is conserved. Likewise, the space components add up to form p of the resultant vector. The four-momentum is, as expected, a conserved quantity.
