# Readers ask: Reddit When Will We Discover Prediction Faster Than Light Speefd?

## Is it possible to travel faster than the speed of light Reddit?

If we follow the current laws of the universe as we understand them, we cannot travel faster than light. It’s literally impossible. Even more amusingly, at about 0.14c (IIRC) time dilation causes the traveler to percieve that they are traveling faster than light.

## Can anything go faster than Lightspeed?

Because the concept of “speed” requires measuring a certain amount of distance traveled in space during a certain period of time, the concept of speed does not even physically exist beyond the speed of light. In fact, the phrase ” faster than light” is physically meaningless.

## Why can’t we go faster than the speed of light Reddit?

If you accelerate, you gain kinetic energy, which can be expressed as E=m*v² (E as energy, m as mass, v as velocity). So, put simply: You can’t go faster than light because there’s not enough energy in the whole universe to accelerate a non-massless particle to the speed of light.

## Will FTL ever be possible?

According to the current scientific theories, matter is required to travel at slower-than-light (also subluminal or STL) speed with respect to the locally distorted spacetime region. Apparent FTL is not excluded by general relativity; however, any apparent FTL physical plausibility is currently speculative.

## Why is light so fast Reddit?

Because it has no mass. All massless particles travel at the speed of light, because to them acceleration is impossible. Any tiny change in momentum would cause an infinite change in speed, so they fly safe at the one and only constant, invariant speed of the universe.

## Will interstellar travel ever be possible Reddit?

Even intergalactic travel may, technically, be possible. At 99.99% of light speed you’ ll reach the Andromeda galaxy in about 3 million years, but due to relativistic time dilation the time experienced by those on-board the ship would be compressed to a few decades.

## 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.

## How fast is the speed of dark?

Is there such a thing as the speed of dark? In a 2013 study, scientists determined that dark matter should have a speed of 54 meters per second, or 177 feet — slow compared to the speed of light.

## Is a black hole faster than light?

Using NASA’s Chandra X-ray Observatory, astronomers have seen that the famous giant black hole in Messier 87 is propelling particles at speeds greater than 99% of the speed of light.

## Is there anything faster than light Reddit?

As far as we know (as far as I know) there is nothing faster than photons at light speed. Under this theoretical framework, nothing can travel faster than the speed of light, and the only things that can travel at the speed of light are massless particles, like photons.

## Who proved Tachyon is faster than light?

Tachyons were first introduced into physics by Gerald Feinberg, in his seminal paper “On the possibility of faster-than-light particles” [Phys. Rev. 159, 1089—1105 (1967)].

## 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.

## Is thought faster than light?

(Phys.org) —Physicist James Franson of the University of Maryland, Baltimore County has captured the attention of the physics community by posting an article to the peer-reviewed New Journal of Physics in which he claims to have found evidence that suggests the speed of light as described by the theory of general
