Amazing Halloween House Display
I have seen a lot of really cool Halloween decorations, but this wins the trophy. I would love to see how this was set up!
Travelling near the speed of light
Light travels through the vacuum space at 299.792,458 meters per second, or approximately 186,282 miles per second. According to Einstein’s theory of special relativity, this is also the maximum speed that energy or matter can travel in the vacuum of space. If you were in a spaceship traveling near the speed of light you would experience interesting effects as you traveled closer to the speed of light. One effect is called time dilation, where time slows down. Of course, from the perspective of moving near the speed of light, this effect of time would not be obvious until you were no longer moving near the speed of light. Another effect is a Doppler effect, where object moving towards you would have compressed light waves and appear to be blue-shifted, and objects moving away from you would have longer light waves and appear to be red-shifted. another effect of moving at or near the speed of light is that as you move towards and past objects, they become distorted and bend.

International Space Station flight over Earth
This Youtube video, viewed by more than 2.4 million people since it was posted Sept. 15, is a time-lapse movie of International Space Station images as it passes over Earth.
The nighttime images begin over the Pacific, passing over North and South America before the space station creates its own sunrise over Antarctica.
Vancouver, Seattle, San Francisco and Phoenix are visible, as well as Texas and New Mexico.
The author, who assembled the images from NASA’s Gateway to Astronaut Photography of Earth, is identified only as “yesterday2221,” age 26.
