# Is it possible to bend space and time?

## Is it possible to bend space and time?

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.

Does light bend space-time?

Light has energy, energy is equivalent to mass, and mass exerts gravitational force. Thus, light creates gravity, i.e. the bending of space-time.

### Do all forces bend space-time?

It turns out that matter effectively curves space-time, but other forces, despite contributing to the stress-energy tensor, lead to some traceless contribution to the theory.

Can magnetic fields bend space?

Magnetic fields flatten curved space and cast doubt on the Universe’s youth. Einstein’s theory of relativity tells us that gravity bends space. Magnetic fields can stiffen space, says Christos Tsagas, just as embedded metal wires can stiffen rubber.

#### Can time travel possible?

General relativity. Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, traversable wormholes, and Alcubierre drives.

Is time Travelling possible?

In Summary: Yes, time travel is indeed a real thing. But it’s not quite what you’ve probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second.

## Can we create gravity?

Artificial gravity can be created using a centripetal force. In accordance with Newton’s Third Law the value of little g (the perceived “downward” acceleration) is equal in magnitude and opposite in direction to the centripetal acceleration.

Does gravity affect time?

Yes, time goes faster the farther away you are from the earth’s surface compared to the time on the surface of the earth. This effect is known as “gravitational time dilation”. The stronger the gravity, the more spacetime curves, and the slower time itself proceeds.

### Can you travel back in time?

Although humans can’t hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. We travel one year in time between birthdays, for example. And we are all traveling in time at approximately the same speed: 1 second per second.

Do black holes exist?

Black holes of stellar mass form when very massive stars collapse at the end of their life cycle. After a black hole has formed, it can continue to grow by absorbing mass from its surroundings. There is consensus that supermassive black holes exist in the centers of most galaxies.

#### Does the ISS have WIFI?

Wi-Fi arrived in space when the National Aeronautics and Space Administration (NASA) installed the first access points (APs) on the International Space Station (Space Station) in 2008. The first Wi-Fi network in space was installed in January 2008 using Wi-Fi 4, the IEEE 802.11n standard.
