“Nothing can be accelerated to the speed of light c” because it will require infinite energy to do so, even for a particle, even more so for a car, why? According to the mv²/2 formula, the energy required for getting to c-speed is finite mc²/2. However, Einstein found that mv²/2 formula is correct only for velocities much smaller than c. The energy formula changes with high velocities because time inside sped up objects slows down, and energy is very sensitive to time: even Joule energy unit strongly depends on time, Joule=kg×m²/sec². If we denote rate of time dilation as D, meaning D=2 if time slows down twice (for 1 second outside the object, 0.5 seconds pass inside the object), then the actual energy formula for any object, moving or stationary, is mc²(D+1/D)/2. How does time dilation D depend on velocity? Einstein’s formula for that is D=1/sqrt(1-v²/c²), where sqrt denotes square root. By this formula, if velocity of the object is half the speed of light, then for 1 second outside this object,
C??tes Du Gr??an: A Short Update On Wine Time Wednesday
Yes that’s right, grape brothers and sisters. Another Wine Time Wednesday(TM) is upon us, which gives me an opportunity to briefly recap what has…
