How Would You Time Travel?

, , , ,

This can be achieved by traveling

at relativistic speeds

or through the effects of gravity. For two identical clocks moving relative to each other without accelerating, each clock measures the other to be ticking slower. This is possible due to the relativity of simultaneity.

Is it possible to travel back in time?

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 it possible to travel faster than light?

General Relativity states that space and time are fused and that

nothing can travel faster than the speed of light

. General relativity also describes how mass and energy warp spacetime – hefty objects like stars and black holes curve spacetime around them.

Can we go back in time if we travel faster than light?

So, simply

going faster than light does not inherently lead to backwards time travel

. Very specific conditions must be met—and, of course, the speed of light remains the maximum speed of anything with mass.

What is the fastest thing in the universe?


Laser beams travel at the speed of light

, more than 670 million miles per hour, making them the fastest thing in the universe.

Can neutrinos travel faster-than-light?

Five different teams of physicists have now independently verified that elusive subatomic particles called

neutrinos do not travel faster than light

. … The OPERA team made headlines after they suggested neutrinos traveled 0.002% faster than light, thus violating Einstein’s theory of special relativity.

Which is faster light or sound?

The

speed of light as it travels through air and space

is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour. … Speed of light in a vacuum and air = 300 million m/s or 273,400 mph.

Can you build a time machine?

Travelling in time might sound like a flight of fancy, but some physicists think it might really be possible. BBC Horizon looked at some of the most promising ideas for turning this staple of science fiction into reality.

Is light faster than darkness?

Most of us already know that darkness is the absence of light, and that light travels at the fastest speed possible for a physical object. … In this respect, darkness has the same speed as light. However, in some instances,

darkness actually moves faster than light

.

What is the fastest natural thing on earth?

Rank 1 Animal
Peregrine falcon
Maximum speed 389 km/h (242 mph) 108 m/s (354 ft/s) Class Flight-diving

Which is the fastest animal on earth?

  • Cheetahs are the world’s fastest land animal, capable of reaching speeds of up to 70 mph. …
  • In short, cheetahs are built for speed, grace, and hunting.

How far can neutrinos travel?

Neutrinos are subatomic particles that have almost no mass and can zip through entire planets as if they are not there. Being nearly massless, neutrinos should travel at nearly

the speed of light

, which is approximately 186,000 miles (299,338 kilometers) a second.

Which particle can travel faster than light?

An Italian experiment has unveiled evidence that fundamental particles known as

neutrinos

can travel faster than light.

How can you break the speed of light?

And while this implies that nothing with real mass can move faster than light, it doesn’t impose a cosmic speed limit, because you can break the speed of light in your backyard. All you have to do is point a

laser beam at the moon

and flick your wrist.

Can sound ever travel faster than light?

Can sound waves travel faster than the speed of light?

Yes

, says Joel Mobley, a physicist at the University of Mississippi in the US. … The phase velocity is the speed at which a wave of a single wavelength moves, and is typically about 1.5 kilometres per second for sound waves in water.
