Yes, wind can travel faster than the speed of sound. ... The speed of sound is not a fundamental speed like the speed of light is. The speed of sound just describes how fast a mechanical wave travels through a material. Different materials have different speeds of sound.

John Houston, Learned lots of physics through KSB. According to Einstein, no information can travel faster than the speed of light. ... According to Einstein, no information can travel faster than the speed of light. However, let's imagine for this example that electricity does in fact travel at the speed of light.

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.

Thanks to a NASA physicist, the notion of warp speed might just travel out of sci-fi and into the real world. NASA's Harold White has been working since 2010 to develop a warp drive that will allow spacecraft to travel at speeds faster than light -- 186,000 miles per second.

Enough already. 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.

There is yet another possible way in which faster-than-light travel is technically possible: rifts in space-time itself that allow a voyager to escape the rules of normal travel.

Electromagnetic waves are waves that can travel through matter or through empty space. spaceship travels faster than the speed of light? In reality, noth- ing travels faster than the speed of light. In empty space, light travels at a speed of about 300,000 km/s.

When bullets fly through the air, they do so at amazing speeds. The fastest bullets travel more than 2,600 feet per second. That's equivalent to over 1,800 miles per hour. To put that in perspective, it's amazing to realize that bullets travel over twice the speed of sound!

Rockets definitely fly faster than jets. A supersonic airplane can fly faster than the speed of sound (1,236 kmh or 768 mph). The SR-71 Blackbird holds the record for fastest jet, flying at 3,418 kmh (2,124 mph). The Space Shuttle, though, accelerates to 29,000 kmh!

The human frame is built to handle running speeds up to 40 miles per hour, scientists say. The only limiting factor is not how much brute force is required to push off the ground as previously thought, but how fast our muscle fibers can contract to ramp up that force.

Nothing can travel faster than the speed of light. But if it could , the conventional wisdom goes, it would travel back in time. ... We used only the velocity addition formula from special relativity, as the other ones (time dilation, length contraction, etc.)

Why can skiers travel faster downhill than human terminal velocity? They can't. ... You frequently hear 120mph bandied about as the terminal velocity of a human in freefall. That figure, however, assumes a human in a position to maximize atmospheric drag, i.e. belly down and limbs extended.

Light waves can travel in vacuum, whereas sound waves cannot travel in vacuum. The speed of light waves in air is 3 x m/s, while that of sound waves in air is 330 m/s at 0. This means that the speed of light is a million times greater than the speed the speed of sound in air.

The speed of sound through air is about 340 meters per second. It's faster through water and it's even faster through steel. Light will travel through a vacuum at 300 million meters per second. ... No information can propagate faster than the speed of light.

In principle, shadows can move faster than the speed of light. ... If the shadow is large enough, it could move across the surface faster than light. This is an illusion that darkness travels faster than the speed of light, and it is still agreed that no physical object can travel faster — since darkness has no mass.

Time Travel Special relativity states that nothing can go faster than the speed of light. If something were to exceed this limit, it would move backward in time, according to the theory. ... If the neutrinos really are traveling faster than light, then they should be time travelers.

In such a scenario, you can travel way faster than light without being even near the relativistic limit c and experiencing no considerable time dilation. This will enable you to see in the 'past'.
