# 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.

### Is it possible to travel back in time?

Time travel is theoretically possible, new calculations show. Time travel is possible based on the laws of physics, according to new calculations from researchers at the University of Queensland. But time-travelers wouldn’t be able to alter the past in a measurable way, they say — the future would stay the same.

Is superluminal travel possible?

If humanity ever wants to travel easily between stars, people will need to go faster than light. But so far, faster-than-light travel is possible only in science fiction. In Isaac Asimov’s Foundation series, humanity can travel from planet to planet, star to star or across the universe using jump drives.

Can we freeze time?

We think that now time is frozen as a change. But we cannot freeze time at all. Because time is also a measure of existence of objects in the Universe. Growth or speed of some of the objects can be stopped totally and we can say time is frozen.

## Would you go blind if time stopped?

If you stopped time, all light and sound would stop, too. In some interpretations, this would leave Strine instantly deaf and blind in his frozen scene. When you slow down electromagnetic waves (light) and pressure waves (sound), you get waves of a lower frequency.

### Is it possible to bend spacetime?

If spacetime can be bent, Beacham continued, it’s theoretically possible that time can be bent. This concept of bending spacetime sprung from Einstein’s theory of General Relativity, which introduced the idea that wormholes could, in theory, act as a bridge between two points that would otherwise be very distant.

Is time travel possible?

One proposed method of time travel is via wormholes. “We know that space can be bent. If space can be bent by, say, gravity, then spacetime can be bent,” Beacham said.

Can we bend space-time in front of and behind a vessel?

Alcubierre’s idea: bending space-time in front of and behind a vessel rather than attempting to propel the vessel itself at light-speeds. According to Alcubierre, in the paper abstract …

## Can we bend space to bend the speed of light?

The speed of light is matter’s fastest speed, but maybe humankind can cheat it. A new scientific theory notes that spacetime itself moves faster than light, so bending a bubble of space around a ship could work. The Cherenkov Effect is a fascinating exception.
