Is the speed of light constant in a vacuum? Is gravity faster than the speed of light? What is the equation for the speed of light? How far can light go in 1 Planck time? What is the speed of light in kilometers per second?
Does Time Exist at the Speed of Light? I do not want to "speculate" but to me, if Light has a frequency and frequency is defined as 1/s or Hertz, then how can time not exist at c, when it is used to define a property of the only phenomena we know to move at c (light)?
What is mean by the specific gravity? what are inertial and non-inertial frames, explain them with proper examples? In relation to physics, explain the terms apparent and absolute magnitudes. Why is sometimes component of some forces added in the same direction and some are equated t...
I realize that GR is the theory of gravity but Dark Energy acts as a sort of force against gravity, I was trying to get to the bottom to if Expansion would be effected by movement or Length Contraction and these equations show that, it would, they also show that Dark Energy is not ...
C. Gravity Run. D. WeRo Kit. 23. What is special about WeRo Kit? A. It hasdifferent levels. B. It is the onlyprize-winner. C. It requiresparental guidance. D. It involvesprogramming skills. B Sometimes a book...
Black holes are areas in space,where gravity is so strong that nothing,not even light,can escape from them.Black holes are thought to be formed by collapsed stars. A supernova is an exploding star. A comet is a bright object with a long tail that travels around the sun. An astero...
"Imagine the gravity of two things pulling on each other, and they're not moving in any way other than the gravitational pull. They will just move directly on the line towards each other. That's a purely radial orbit," said Chris Mihos, an astronomer at Case Western Reserve University ...
I would just like to pose a question which contradicts the above statement (I know I am wrong btw, I want to see where I am going wrong).My understanding of space (not near any gravity and therefore no spacetime curvature) is that a body in motion will continue...
This mode provides more torque and engine power to work against gravity. Many people think that the L mode provides more power to the wheels that it is helpful for everyday driving, but this is not true. This will cause the brakes to overheat and eventually fail to work. The L mode in...
Though photon have no mass, why gravity attracts it? Why does the filament of a bulb not melt though as it heats to more than 3400^oC? All objects radiate energy. Why, then, are we not able to see all the objects in a dark room? Why does a particle mov...
