A postulate of the Special Theory of Relativity says that the mass of a body increases as compared to the mass at rest as the body speeds up to relativistic speeds. The mass of the moving object can be obtained by multiplying the mass of the body at rest by the Lorentz factor. This increase in the relativistic mass reduces the effect of every extra unit of energy put into accelerating the object, on the speed of the object. <\/p>\n\n\n\n
Instead, as the speed of the object increases and starts to approach significant fractions of the speed of light, the portion of energy being spent into making the object more massive gets bigger. Any extra energy would thus be spent in making the object more massive instead of increasing its speed.<\/p>\n\n\n\n
The formulae for calculating relativistic mass and mass-energy equivalence will show us that we will need more energy than the total energy content of the universe<\/em> in order to attain such speeds. In a word – impossible. <\/strong>At least based on our current understanding of physics.<\/p>\n\n\n\nHaving said that, it is safe to confidently state that it is impossible for any object with a mass to attain the speed of light. For time travel, we’ll need to look into exotic concepts such as wormholes.<\/p>\n","protected":false},"excerpt":{"rendered":"
Some questions that human beings have grappled with for centuries still manage to boggle us with amusing answers and facts. One concept that has interested all researchers, academicians and science enthusiasts alike is light – its properties, and speed being the most riveting of them all. So, what actually happens as one approaches \u2018light-speed\u2019?
