Question

near the speed of light

Answer 1

, an object's mass increases exponentially. This phenomenon is described by Einstein's theory of relativity, specifically the equation E=mc^2, where E is energy, m is mass, and c is the speed of light in a vacuum. As an object accelerates towards the speed of light, its mass increases, requiring more energy to continue accelerating. This increase in mass leads to a decrease in acceleration, making it increasingly difficult for an object to reach the speed of light. Additionally, approaching the speed of light also leads to time dilation and length contraction, further complicating the ability to achieve such incredible speeds.
