What if speed of light 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 infinitely fast?

For centuries, physicists thought there was no limit to how fast an object could travel. But Einstein showed that the universe does, in fact, have a speed limit: the speed of light in a vacuum (that is, empty space). Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second).

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?

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.

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. Achieving those speeds, however, is incredibly unlikely and probably impossible.

Why isn't anything faster than the speed of light?

Hence, an object moving at the speed of light through space experiences no time at all or in other words is frozen in time. So, the real reason why we can't move faster than the speed of light is that once we're moving entirely through space, there's no more speed to be gained.

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.

Can we see future if we travel faster than light?

As far as we know, nothing can go faster than light. However, 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. So it is theoretically possible to travel to the future, but one could not return.

Is anything theoretically faster than light?

In special relativity, the speed of light is the ultimate speed limit to the universe. Nothing can travel faster than it.

Can speed of light stop time?

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.

How fast is the 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.

What are the 3 things faster than light?

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.

At what speed does time stop?

The faster the relative velocity, the greater the time dilation between one another, with time slowing to a stop as one approaches the speed of light (299,792,458 m/s).

How many dimensions exist?

The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there's the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.

Does time stop in a black hole?

Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in time at the edge of the hole.

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.

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.

Is The Dark faster than light?

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 1 light-year in human years?

For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). That is a 6 with 12 zeros behind it!

How long would it take to travel 500 light-years at the speed of light?

Answer and Explanation: Since a light-year is the distance travelled by light in one year while travelling with the speed of light i.e. 3×108m/s 3 × 10 8 m / s , it would take 500 years to travel the distance of 500 light-years at the speed of light.
