What happens if you travel at the speed of light?
This upper bound is the speed of light. So, nothing can travel faster than light. Then what happens if you do travel at the speed of light? The complications arise because our observations depend upon our velocity. The space-time continuum can contract or expand as per the velocity.
What happens if you turn your headlights on while driving?
One of the most popular questions from our "ask a physicist" feature was, "What happens if you're driving at the speed of light and you turn on your headlights?" The simple answer: You can't. So quit trying.
What happens to the speed of light at 99%?
Typically on earth, it's an effect of about 1 part in a quadrillion, but at 99% the speed of light, you'll appear to be running at only 1/7th speed. The length contraction and time dilation conspire (out of mathematical necessity) to make your high beams move at the speed of light to somebody watching you from the side.
Why do high beams move at the speed of light?
The length contraction and time dilation conspire (out of mathematical necessity) to make your high beams move at the speed of light to somebody watching you from the side. But just as a baseball gets a boost of energy when you throw it on a train (which you shouldn't do, incidentally) the light gets a boost of energy as well.
What would happen if a golf ball hit the Earth at the speed of light?

So why didn't it just completely obliterate the whole earth well the reason is because a grain of sand going that speed.
What happens if an object hits something at the speed of light?
It travels at a steady rate of 186,282 miles (299,792 kilometers) per second. Even if it were physically possible to propel ourselves to such speeds (spoiler alert: it isn't), as you gain the necessary momentum to match the speed of light, your mass would become infinite.
What happens if a coin hits the earth at the speed of light?
Nothing. If a penny or anything with mass travels at the speed of light then it can't also be a part of our universe where our laws of physics prohibits mass from travelling at the speed of light.
What if you throw a ball at the speed of light?
If you threw a baseball at the speed of light, the ball would move 299,792,458 kilometers per second. Unlike light, a baseball has mass — as it approaches the speed of light, its mass would increase towards infinity.
When can you leave Earth at the age of 15?
If you leave Earth at the age of 15 in a spaceship at the speed of light and spend 5 Years in space, when you get back on Earth you will be 20 years old and all your friends who were 15 when you left will be 65 years old. This phenomenon is known as "Time Dilation" in Physics.
Does time exist at 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.
Will Earth be swallowed by a black hole?
Despite their abundance, there is no reason to panic: black holes will not devour Earth nor the Universe. It is incredibly unlikely that Earth would ever fall into a black hole. This is because, at a distance, their gravitational pull is no more compelling than a star of the same mass.
What if a needle hits the ocean at the speed of light?

What if a black hole appeared on Earth?
What would happen if an asteroid-mass black hole were to hit Earth? In short, catastrophe. The black hole would puncture our planet's surface like a hot knife through butter, but it would immediately begin to slow down because of its gravitational interaction with Earth.
What would happen if you tried to hit a baseball pitched at 90% the speed of light?
What would happen if you tried to hit a baseball pitched at 90% the speed of light? The answer turns out to be “a lot of things”, and they all happen very quickly, and it doesn't end well for the batter (or the pitcher).
What if you threw a baseball at 90% the speed of light?
Throwing A Baseball At 90 Percent Speed Of Light Would Kill Thousands.
Why can light travel at the speed of light?
Since photons are massless, they travel at c, which is called the speed of light because the photon was the first known example of a massless particle. So the short answer to the question is that a photon knows to travel at the speed of light because it is massless.
What happens when you hit the speed of light?
As you get closer and closer to the speed of light, time gets slower and slower compared to stationary observers. So if you really need an answer to the original question, this means that if you actually hit the speed of light for real, time would stop entirely, which means that nothing could happen.
How fast can you run at 99% light speed?
Typically on earth, it's an effect of about 1 part in a quadrillion, but at 99% the speed of light, you'll appear to be running at only 1/7th speed .
What would happen if you held a mirror in front of you?
If you held a mirror in front of you, you'd look exactly as you always have. In fact, one of the surprising things about special relativity is that if you weren't looking at all of the scenery passing you, you couldn't tell that you are moving at all.
Why are people confused about relativity?
Part of the reason that people are so confused about this aspect of relativity is that it flies in the face of everyday experience. If I'm in a boxcar moving 60 mph and throw a 90 mph fastball, someone standing by the side of the tracks will see the ball moving at 150 mph. It seems like the same logic should work with light. Except that it doesn't.
When did Michelson and Morley find that light travels at the same speed?
Michelson and Morley found in 1887 that light travels at the same speed to all moving observers, a result that doesn't make sense unless special relativity is correct. All of modern physics (and technology) is built on an edifice of special relativity, and so far, it's proven ridiculously accurate.
Is physics confined to light speed?
Sadly, physics teaches that we are forever confined to sub-light speeds. There were several comments, in response to the original call for questions, that took umbrage at this certainty on the part of physicists.
Does a baseball light go faster?
The difference is that it doesn't go faster ; it just looks bluer. In this case, your headlights would be boosted into the ultraviolet.
When You Travel at The Speed of Light
Relative Variation of Observation Due to Speed
- The increase in our speed makes us see things differently. According to the Lorentz’s transformation, there is variation in the observation according to speed. The time runs slower and length contracts for the one who is speeding. For the one speeding nearly at the speed of light, this effect becomes more significant. The squared ratio of velocity ...
The Mathematical Aspects of Travel at The Speed of Light
- If we look mathematically, the picture is far more agitated and further difficult to comprehend. The observation is actually observer-dependent. So, if an observer at rest sees one travelling at the speed of light, its length is mathematically zero. The mass is mathematically infinite and a second takes infinitely long time. Now let us try to figure things in the opposite way. If I am travelling at t…
Beyond The Speed of Light
- The mathematical formulas pose a limitation to the extent of our speed. Since mathematics results infinities after infinities beyond the speed of light, it is not convincing. The experimental results considering the velocity of light constant is satisfactory. This might have established this theory firmly. But, we need greater detail. Though particles as electrons have been accelerated n…
