What if light speed was infinite?

If the speed of light was infinite, all points in the universe would be able to communicate with each other instantaneously. We wouldn't be able to tell which stars are further away or older etc. Our universe would be one instantaneous here and now. No past, no present and no future.

What happens if light speed is infinite?

Then again, if the speed of light were infinite, massless particles and the information they carry would move from A to B instantaneously, cause would sit on top of effect and everything would happen at once. The universe would have no history and no future, and time as we understand it would disappear.

What if the speed of light was faster?

So changing the speed of light would have no effect on anything. The energy of a photon of light is equal to Planck's constant multiplied by the frequency.

Is the speed of light actually infinite?

Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second). Only massless particles, including photons, which make up light, can travel at that speed. It's impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so.

What would the universe look like if the speed of light was infinite?

A big gray, infinite canvas with nothing on it. We would not have light waves at all. Since light would be absorbed as it was emitted, there could be no light waves, wave packets or anything.

Why isn't the speed of light infinite? What if it were?

Does time exist beyond the speed of light?

Space and time simply don't exist at and beyond the speed of light in vacuum. Therefore, taking the limit towards c simply reaffirms the two postulates. Since there is no valid reference frame at the speed of light in vacuum, there is also no way for an object with mass to ever go exactly the speed of light.

Have we found anything faster than light?

Nothing in the universe can go faster than the speed of light. As it happens, it was an illusion, a study published in the journal Nature explained earlier this month.

Why doesn't light travel at infinite speed?

That something, the universal conversion factor, is the speed of light. The reason that it is limited is simply the fact that a finite amount of space is equivalent to a finite amount of time.

What is speed of dark?

Darkness travels at the speed of light. More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light. Any time you block out most of the light – for instance, by cupping your hands together – you get darkness.

How fast is 20% the speed of light?

Traveling at around 20 percent the speed of light—so as fast as 100 million miles per hour—the craft and their tiny cameras would aim for the smallest but closest star in the system, Proxima Centari, and its planet Proxima b, 4.26 light-years from Earth.

Can the speed of light be stopped?

And there's an ultimate cosmic speed limit that applies to every object: nothing can ever exceed the speed of light, and nothing with mass can ever reach that vaunted speed.

Why can't anything go faster than light?

The speed limit is a harsh reality

The reason that it is hard to travel through space at the speed of light is that you must push the object out of moving in the time direction to moving more in the space direction.

Why is light so fast?

That's because all massless particles are able to travel at this speed, and since light is massless, it can travel at that speed.

How much time would pass on Earth if I traveled at the speed of light for a year?

At 99.99999 percent of the speed of light, for a year, more than 2000 years would pass on Earth. The point is, the closer you get to the speed of light, the more time dilation is experienced.

How fast is the actual speed of light?

So what does this sentence really mean? Surprisingly, the answer has nothing to do with the actual speed of light, which is 300,000 kilometers per second (186,000 miles per second) through the "vacuum" of empty space.

Will a photon travel forever?

From the perspective of a photon, there is no such thing as time. It's emitted, and might exist for hundreds of trillions of years, but for the photon, there's zero time elapsed between when it's emitted and when it's absorbed again. It doesn't experience distance either.

Is light or dark faster?

Shadow Racing

This is a little hard to wrap your head around, but shadows can move faster than the speed of light, even though nothing can move faster than the speed of light. In a second, we'll explain how exactly that's possible without breaking the most fundamental law of physics.

What is the fastest thing in the universe?

So light is the fastest thing. Nothing can go faster than that. It's kind of like the speed limit of the universe.

What is the real speed of sound?

speed of sound, speed at which sound waves propagate through different materials. In particular, for dry air at a temperature of 0 °C (32 °F), the modern value for the speed of sound is 331.29 metres (1,086.9 feet) per second.

Why do you go back in time if you travel faster than light?

This phenomenon is called 'time dilation'. Dr Sean Matt, an expert in astronomy and astrophysics from the University of Exeter in the UK, says, "If one travels close to the speed of light, time behaves differently than we are used to, and in this way, one can move forward in time faster than those left behind.

Will humans ever develop faster than light travel?

In 1947 humans first surpassed the (much slower) speed of sound, paving the way for the commercial Concorde jet and other supersonic aircraft. So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no.

Will humans develop faster than light travel?

The fact is we'll never be able to travel beyond the speed of light, at least based on our current understanding of established physics. As any object with mass accelerates – like a proton in the LHC – it gains energy, always needing just a little bit more energy to accelerate even further.

Would time stop if you traveled at the speed of light?

If you were able to travel at the speed of light, all of your motion would be wrapped up in getting you to travel at the maximum speed through space, and there would be none left to help you travel through time — and, for you, time would stop. At the speed of light, there is no passage of time.
