The statement "there is no limit to how fast something could go" is not accurate according to our current understanding of physics. According to Einstein's theory of relativity, the speed of light in a vacuum, denoted as "c," represents an upper limit for the velocity of any object or information in the universe. The speed of light is approximately 299,792,458 meters per second.
According to the theory of relativity, as an object with mass approaches the speed of light, its relativistic mass increases, requiring an infinite amount of energy to reach or exceed the speed of light. This is commonly referred to as the mass-energy equivalence principle (E=mc^2), where "m" represents mass and "c" represents the speed of light.
Furthermore, as an object with mass accelerates towards the speed of light, its relativistic effects become significant. Time dilation occurs, causing time to appear to slow down for the object in motion relative to a stationary observer. As the object's speed approaches the speed of light, time dilation becomes more pronounced, making it increasingly difficult to accelerate further.
In essence, the theory of relativity establishes a fundamental limit on the speed at which matter, energy, or information can travel. Therefore, objects with mass cannot exceed the speed of light, and that's why they are not going faster than the speed of light at present.
