How fast is light? Nothing on earth is known to move faster, and in my opinion, we are actually very fortunate to be able to measure it. Aside the fact that light enables us to see, I am appreciative of it even more because if it were to get any faster by any stretch, astronomers would have to build new technology to measure its speed. This speed of light is known as the cosmic speed limit and even at the age of twenty-two, I am yet to experience anything more rightfully named. Why is It so hard for us to travel at the speed of light? The reason is that as you propel an object faster and faster, its relative mass compared to when the object is at rest, increases. This means that not only do we increase the speed object; we end up increasing the object’s mass as well, eventually resulting in an infinite mass which requires an infinite amount of energy to move it.

I really appreciate that you add your own reasons for why you think this is a fascinating topic! I also appreciate that you explain why it’s so hard to travel at the speed of light. I always thought it was just because it was too fast. I didn’t know that we end up increasing the object’s mass as well. The concept of infinite energy is really interesting to me. I wonder why light is able to move that fast?
