Will we ever reach light speed?

Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. According to Albert Einstein's theory of special relativity, summarized by the famous equation E=mc², the speed of light (c) is something like a cosmic speed limit that cannot be surpassed.

How close to the speed of light can we get?

The most energetic particles ever made on Earth, which are protons at the Large Hadron Collider, can travel incredibly close to the speed of light in a vacuum: 299,792,455 meters-per-second, or 99.999999% the speed of light.

Can we go 1% the speed of light?

It's possible to get something to 1% the speed of light, but it would just take an enormous amount of energy.

When can you leave Earth at the age of 15?

If you leave Earth at the age of 15 in a spaceship at the speed of light and spend 5 Years in space, when you get back on Earth you will be 20 years old and all your friends who were 15 when you left will be 65 years old. This phenomenon is known as "Time Dilation" in Physics.

Is time Travelling possible?

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. And there are important reasons why we need to understand this real-world form of time travel.

Faster Than Light Speed Travel With Neil deGrasse Tyson

Is NASA working on light speed?

NASA Engineer Says New Thruster Could Reach 99% Speed of Light.

Will humans ever travel to other galaxies?

The technology required to travel between galaxies is far beyond humanity's present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.

How fast can humans travel without dying?

Most of us can withstand up to 4-6G. Fighter pilots can manage up to about 9G for a second or two. But sustained G-forces of even 6G would be fatal. Astronauts endure around 3G on lift-off, one G of which is Earth's own pull.

How fast is 9 g's?

Normal humans can withstand no more than 9 g's, and even that for only a few seconds. When undergoing an acceleration of 9 g's, your body feels nine times heavier than usual, blood rushes to the feet, and the heart can't pump hard enough to bring this heavier blood to the brain.

Is warp drive faster than light?

A warp drive is a device that distorts the shape of the space-time continuum. A spacecraft equipped with a warp drive may travel at speeds greater than that of light by many orders of magnitude.

What happens if you turn on a flashlight at the speed of light?

The short answer is that light coming out of your torch instantly reaches the speed of light. Light can only ever travel at the speed of light — 300,000,000 metres per second in a vacuum, and a bit slower in air because it bumps into molecules. So why is light only allowed to travel at that one speed?

What is inside a black hole?

The singularity at the center of a black hole is the ultimate no man's land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down. And it doesn't really exist.

Will humans ever leave the Solar System?

Climate change is altering our planet, and some have wondered if we may have to leave Earth to another distant planet. We will never escape climate change, and unfortunately, we will never leave the Solar System, and Earth may be our home forever.

Is warp speed possible?

“None of the physically conceivable warp drives can accelerate to speeds faster than light,” Bobrick says. That is because you would require matter capable of being ejected at speeds faster than light—but no known particles can travel that fast.

How fast is warp speed?

In the sci-fi universe of "Star Trek," spaceships with warp drives can zoom past the normally impenetrable limit of light speed, or about 186,282 miles per second (299,792 kilometers per second) in a vacuum.

Do wormholes exist?

Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They've never been seen, but according to Einstein's general theory of relativity, they might exist.

Does time stop in a black hole?

Time does stop at the event horizon of a black hole, but only as seen by someone outside the black hole. This is because any physical signal will get infinitely redshifted at the event horizon, thus never reaching the outside observer. Someone falling into a black hole, however, would not see time stop.

Where would a black hole take you?

By their calculations, quantum mechanics could feasibly turn the event horizon into a giant wall of fire and anything coming into contact would burn in an instant. In that sense, black holes lead nowhere because nothing could ever get inside. This, however, violates Einstein's general theory of relativity.

Can you destroy a black hole?

Black holes are among the most destructive objects in the universe. Anything that gets too close to a black hole, be it an asteroid, planet, or star, risks being torn apart by its extreme gravitational field. By some accounts, the universe may eventually consist entirely of black holes.

What planet could we live on?

Kepler-62e and Kepler-62f are thought capable of hosting life. The planet Kepler-69c is located about 2,700 light-years from Earth in the constellation Cygnus. This is an illustration of the planet, which is the smallest yet found to orbit in the habitable zone of a sun-like star.

Will Voyager 1 ever stop?

Voyager 1 is expected to keep its current suite of science instruments on through 2021. Voyager 2 is expected to keep its current suite of science instruments on through 2020.

Is Earth the only planet with life?

Earth is the only planet in the universe known to possess life. The planet boasts several million described species, living in habitats ranging from the bottom of the deepest ocean to a few miles up into the atmosphere. Researchers think far more species remain that have yet to be described to science.

Why does Lightspeed stop time?

In the limit that its speed approaches the speed of light in vacuum, its space shortens completely down to zero width and its time slows down to a dead stop. Some people interpret this mathematical limit to mean that light, which obviously moves at the speed of light, experiences no time because time is frozen.

Is light faster than darkness?

Darkness Is Faster Than the Speed of Light.
