Match the units to their metric weight: How fast is the Pacific Plate moving to form the Hawaiian island chain? You have just heard a report on the radio of a series of very destructive earthquakes that occurred from 5 to 150 kilometers below the surface of the Earth and affected an area...
Think of it like this: Observers sitting on a train could look at a train moving along a parallel track and think of its relative movement to themselves as zero. But observers moving nearly the speed of light would still perceive light as moving away from them at more than 670 million mp...

It is not possible to hold a galaxy in place to see if its emitted light shifts to shorter wavelengths, but the use of direct measurements of light speed on the moving earth can provide evidence for or against the notion. The constant total velocity of light in its propagation direction in...
What is the wavelength of an electron moving at a velocity of 0.77*c where c is the speed of light? (in meters) Radio communications travel at the speed of light (2.9979 x 108 m/s). How long will it take for a radio transmission to reach a space prob...
redshift measurements of distant galaxies showed that the expansion of the Universe has been accelerating for the past few billion years. This has led to theories like “Dark Energy“, where an unseen force is driving the expansion of space itself instead of objects moving through it (thus not...
A supermassive black hole is racing across the universe at110,000 mph (177,000 km/h), and the astronomers who spotted it don't know why. The fast-moving black hole, which is roughly 3 million times heavier than our sun, is zipping through the center of the galaxy J0437+2456, about ...
What does a light beam look like when it is not moving ?Maybe... * This opens new possibilities for storingquantum statesin futurequantum computers. The key totransferring informationusing quantum states of light, is to be able to decode the information. To do this, one has to slow down ...
