Can Anything With Mass Travel at the Speed of Light
The speed of low-cal in a vacuum is an absolute cosmic speed limit. Nada can go faster than three.0 10 108 meters per second (that's 300,000,000 grand/s or 1,080,000,000 km/h!). According to the laws of physics, as nosotros approach light speed, we take to provide more and more than energy to make an object move. In social club to reach the speed of calorie-free, you lot'd need an infinite amount of energy, and that's impossible!
Take you ever been on a fast train or in an airplane? Did you notice that you lot got bigger during your trip?
You lot may have heard that an object traveling at the speed of low-cal gains space mass. But that's not exactly true. The object doesn't actually gain physical mass but it behaves like information technology has. For example if a 65kg person was travelling at 50% of the speed of low-cal, they would behave like they had a mass of 87kg. At 90%, they would bear as if they weighed 172kg.
So, if mass can't travel at the speed of light, how come up light can? Lite is made up of photons, which aremassless particles and therefore they don't require free energy to motion.
If it doesn't accept any effort to move light particles, why can't photons travel faster than light speed?
Fourth dimension dilation. Time slows down equally you approach the speed of low-cal and when you reach information technology, time stops. For a photon, there is no time, everything happens instantaneously. Trying to make a photon go faster than the speed of light is similar bringing your car to a stop and trying to go slower. It can't be washed!
Time dilation affects us all the fourth dimension in everyday life, only its effects are so modest we tin't meet it. According to the theory of relativity, "moving clocks run deadening." Pregnant that if you throw your clock off a cliff, the time it showed would be slightly behind a clock that wasn't thrown off a cliff. This is the example for all clocks, mechanical and biological. You actually age slower at such loftier speeds, simply you would take to travel pretty fast to notice much of a divergence. For example, someone who has been on the international space station for 6 months will have anile 0.005 seconds slower than someone here on earth. The ISS travels effectually the earth in one case every 90 minutes, simply this is however only 0.003% of the speed of calorie-free. If y'all travelled in a space transport at 98% of the speed of low-cal for just a few minutes, decades would accept passed on globe for your friends.
If we could see what was going on, a person travelling towards you at light speed would appear blue since the light waves that bounce off them and into your eye will have been squished and compacted together, making the wavelength shorter. We call this blueshift. Similarly, if the person was travelling away from you, the light waves would be stretched, making the wavelength longer and they would appear reddish, and we phone call that redshift. For the person travelling at light speed, everything in forepart of them would be squished together into what looks similar a blurry tunnel, the outer ring of the tunneled would announced carmine and the inside blue.
