What if light speed was infinite?

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.

Was the speed of light slower in the past?

Anyone who took Physics 101 has had this fact drilled into their head: The speed of light is a constant, traveling at 186,000 miles per second.

What would happen if you were faster than the speed of light?

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.

Can we go 50% the speed of light?

The speed of light in a vacuum is an absolute cosmic speed limit. Nothing can go faster than 3.0 x 108 meters per second (that’s 300,000,000 m/s or 1,080,000,000 km/h!). According to the laws of physics, as we approach light speed, we have to provide more and more energy to make an object move.

Can we go 20 the speed of light?

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.

Can we outrun light?

No. The universal speed limit, which we commonly call the speed of light, is fundamental to the way the universe works.

Does light speed stop time?

The simple answer is, “Yes, it is possible to stop time. All you need to do is travel at light speed.” The practice is, admittedly, a bit more difficult. Addressing this issue requires a more thorough exposition on Special Relativity, the first of Einstein’s two Relativity Theories.

Would you age if you Travelled speed light?

Five years on a ship traveling at 99 percent the speed of light (2.5 years out and 2.5 years back) corresponds to roughly 36 years on Earth. When the spaceship returned to Earth, the people onboard would come back 31 years in their future–but they would be only five years older than when they left.

Does light ever lose speed?

The speed of light is not only the fastest speed that anything in the Universe can travel, it’s regarded as a universal constant. Whether we shine a flashlight, look at the Moon or Sun, or measure a galaxy from billions of light years away, the speed of light is the one thing that never changes.

What is dark speed?

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.

Is anything faster than light?

So, according to de Rham, the only thing capable of traveling faster than the speed of light is, somewhat paradoxically, light itself, though only when not in the vacuum of space. Of note, regardless of the medium, light will never exceed its maximum speed of 186,282 miles per second.

Why can’t we go faster then light?

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. And this is a more accurate reason than the reasoning of changing masses.

What is 1% the speed of light?

While 1% of anything doesn’t sound like much, with light, that’s still really fast – close to 7 million miles per hour! At 1% the speed of light, it would take a little over a second to get from Los Angeles to New York. This is more than 10,000 times faster than a commercial jet.

Does the past still exist?

In short, space-time would contain the entire history of reality, with each past, present or future event occupying a clearly determined place in it, from the very beginning and for ever. The past would therefore still exist, just as the future already exists, but somewhere other than where we are now present.

Is light faster than sound?

As a rule sound travels slowest through gases, faster through liquids, and fastest through solids. The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour.

Can light travel forever infinitely?

If there were no objects to absorb light, it would keep traveling forever. Light is made up of particles called photons that travel like waves. Unless they interact with other particles (objects), there is nothing to stop them.

Can light go on infinitely?

As long as nothing absorbs it, the light keeps on traveling forever.

Is light speed infinite speed?

The common experience of turning on a light switch certainly shows that light travels very quickly. But careful experiments reveal that it travels at a finite speed. This speed, which we call “c,” is measured to be 300,000,000 meters per second.

Is there a limit to light speed?

Sure, because it is not a local speed. The speed of light limitation is only local – nothing can fly faster than the speed of light (relative to you) near you. However, far far away, there are different rules. The universe expands.
