why is dark matter called cold? Cold refers to the fact that the dark matter moves slowly compared to the speed of light, while dark indicates that it interacts very weakly with ordinary matter and electromagnetic radiation.
How was dark energy discovered? Dark energy was discovered in1998 by two teams of astronomers, who measured light coming from explodingstars called Type IA supernovae, known as “standard candles” fortheir consistent brightness.
Are dark-colored shingles better? If you live in a cold climate with long winters and short summers, getting dark-colored shingles is ideal as they absorb heat from sunlight and can help warm the higher levels of your home. Having a dark-colored roof also helps in melting the snow that collects on your rooftop quickly.
Why was the discovery of dark matter so important? Dark matter played an important role in the formation of galaxies. Researchers use astronomical surveys to build maps of the location of dark matter in the universe based on how the light from distant galaxies bends as it travels to us.

What is dark matter made from?
Most scientists think that dark matter is composed of non-baryonic matter. The lead candidate, WIMPS (weakly interacting massive particles), are believed to have ten to a hundred times the mass of a proton, but their weak interactions with “normal” matter make them difficult to detect.

Can dark energy run out?
As dark energy continues to expand the Universe, the quanta that exist will all decay, fly apart, or redshift until they reach arbitrarily large wavelengths.
