How Does Light Travel

The Cosmic Velocity Limit Referring to Einstein's unique relativity theory, the velocity of light is constant in a vacuum, and that can’t be exceeded by any object. In other words, nothing can travel at a speed higher than that of light. It’s the cosmic velocity limit for data exchange. The…

Perpetual Motion Machines

Perpetual Motion is the kind of movement that continues without any energy supply from external sources. Nevertheless, it’s hard to determine any motion as completely perpetual. The word perpetual signifies 'indefinite and uninterrupted'. Hence, a perpetual motion machine can be defined as a theoretical machine that operates without absorbing power.…
