![]() Wormholes are hypothetical, but their mechanism is quite intriguing, and in a way, if it were possible, they are supposedly faster than the speed of light. If there were something more efficient than traveling with the speed of light, it would be traveling through wormholes. Some galaxies are moving away from our Milky Way faster than the speed of light, and this is happening because space itself is moving along with them. If you were to hold a torch and run with it, the speed of its light would still travel at the same rate. Since space is theoretically “nothing,” it isn’t susceptible to the laws of physics. Scientists have demonstrated that the Universe is expanding, and this expansion is even faster than the speed of light. It appears that nothing is faster than the speed of light, but the Universe, as always, eludes our perception once again. Is There Anything Faster Than the Speed of Light? In theory, it seems that nothing is faster than the speed of light, or is there? Let’s find out. If you traveled around the Earth with the speed of light, you would make a complete tour of our planet 7.5 times in just one second. However, if our spacecraft would be traveling at the speed of light, we would reach the Sun in only 8.3 minutes. If you want an example of how fast the speed of light is, think about this, if we were to launch an imaginary spacecraft from Earth that would travel at around 153,454 mi / 246,960 km per hour constantly, it would reach the Sun in 606 hours, or 25 days. It seems that nothing can be faster than the speed of light. In water, the speed of light is slower, at 225,000 km / 139,808 mi per second, and 200,000 km / 124,274 mi per second in glass. In terms of seconds, light travels at around 300,000 kilometers per second or 186,000 miles per second in a vacuum. In miles per hour/mph, the speed of light is at around 670,616,629, while in kilometers per hour, light travels at 1,079,252,848. The speed of sound travels at around 343 m/s, while the speed of light travels at 299,792,458 m/s. And if indeed they existed, an infinite quantity of energy is needed to ‘slow them down’ relatively to the speed of the light.With our current understanding of motion, it seems that the speed of light is the highest of all, being 874,030 times faster than the speed of sound. The suggestion of the presence of the tachyons, the ‘faster-than-light particles’ has been made. However, atom’s parts with no mass are the only that can move at the speed of light. This scenario has been explained by relativity which stipulates that an infinite quantity of energy is needed to power the object to that speed of light. Any huge object can project at a speed close to that of light but will not achieve it. There is no other object with the same speed as light, and therefore the speed of light has been taken as the ultimate speed limit. Why Is Speed of Light Deemed to Be the Ultimate Speed Limit? For example, the derivation of Maxwell’s equation has shown some hint that "c" must remain constant. The steadiness of the speed of light has been put into use especially in physics. The question is “Who gave the General Conference of Weight and Measures (CGPM) the right to outline the speed of light and using the meter as a unit of measurement?” The answer to this question is found in the fact that the speed of light in a void space is a universal constant and hence give every observer the right to use "c" to denote the speed of light. As by the special relativity and the experiments that support it, the speed of light is similar to all standing observers. The photons that constitute light have no rest mass, and therefore they always travel at this speed, hence the formulation of the name “speed of light” represented by letter "c". Therefore, the speed of the light denoted by letter "c" is 299,792,458 meters per second to be precise. The period between the time when the light was emitted and when we see it is called lookback time. To our surprise, the light that enables us to see the Andromeda Galaxy left the galaxy two million years ago before even the human species evolved. The fastest rocket currently travels at a speed of 30,000 miles per hour and even if we improve with time to the speed of light, it will still take us two million years to arrive at the Andromeda Galaxy. The difference between this galaxy and the cities we see on our television is that we can visit these cities one day if we wish but we will never visit the Andromeda Galaxy because of the distance. We can even see a distant object like the famous Andromeda Galaxy situated two million light-years away from the earth.
