speed of light

Gravity would stop the self rotation by tidal forces, such as cause the tides on Earth. This would convert rotational energy into heat leading ultimately to body or bodies rotating with the same frequency as the orbital motion.

Dave: In space, it is possible to create “artificial gravity” by spinning your spacecraft or space station. Technically, rotation produces the same effect as gravity because it produces a force (called the centrifugal force) just like gravity produces a force.

“We know that space can be bent. 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.

According to Einstein’s general relativity, it is impossible to tear the fabric of space. Black holes are another example of space stretched to its limit, and there is a strong experimental basis for believing that black holes exist. String theorists believe that the fabric of space can tear in specific ways.

As long as a wormhole has a greater mass than any black hole it encounters, it should remain stable. If a wormhole encounters a larger black hole, the black hole may disrupt the wormhole’s exotic matter enough to destabilize the wormhole, causing it to collapse and likely form a new black hole, Gabella said.

Do wormholes have gravity? Worm holes are an artificial, mathematical construct from the equations of relativity. Wormholes are a portal from one side of spacetime to the other. Since spacetime defines gravity, a wormhole is an extreme case of spacetime having no gravity.

The main difference would be that a wormhole is a shortcut from one part of the universe to another, while a black hole is a giant suction device. Also, wormholes’ existence is only still hypothesized, while we have proof of the existence of black holes.

In principle, building a wormhole is pretty straightforward. According to Einstein’s Theory of General Relativity, mass and energy warp the fabric of space-time. And a certain special configuration of matter and energy allows the formation of a tunnel, a shortcut between two otherwise distant portions of the universe.

Unusual flashes of gamma rays could reveal that what appear to be giant black holes are actually huge wormholes, a new study finds. Einstein’s theory of general relativity suggests wormholes are possible, although whether they really exist is another matter. In many ways, wormholes resemble black holes.

The concept that black holes may exist that are smaller than stellar mass was introduced in 1971 by Stephen Hawking. It is possible that such quantum primordial black holes were created in the high-density environment of the early Universe (or Big Bang), or possibly through subsequent phase transitions.

Even light, the fastest-moving thing in our universe, cannot escape – hence the term “black hole.” The radial size of the event horizon depends on the mass of the respective black hole and is key for a person to survive falling into one. A person falling into a supermassive black hole would likely survive.
