In photography , the golden hour is the period of daytime shortly after sunrise or before sunset , during which daylight is redder and softer than when the Sun is higher in the sky. The opposite period during twilight is blue hour , just before sunrise or after sunset , when indirect sunlight is evenly diffused. When the Sun is low above the horizon , sunlight rays must penetrate the atmosphere for a greater distance , reducing the intensity of the direct light , so that more of the illumination comes from indirect light from the sky Thomas , 913 , reducing the lighting ratio. More blue light is scattered , so if the Sun is present, its light appears more reddish. In addition, the Sun's low angle above the horizon produces longer shadows. The term hour is used figuratively; the effect has no clearly defined duration and varies according to season and latitude. The character of the lighting is determined by the sun's altitude , and the time for the Sun to move from the horizon to a specified altitude depends on a location's latitude and the time of year Bermingham ,

Since the late s, astronomers have been aware of the fact that the Universe is in a state of expansion. This led to the theory of Dark Energy , a mysterious invisible force that is driving the expansion of the cosmos. A new study from the University of British Columbia UBC seeks to do just that by postulating the Universe is expanding due to fluctuations in space and time. The team began by addressing the inconsistencies arising out of the two main theories that together explain all natural phenomena in the Universe. These theories are none other than General Relativity and quantum mechanics, which effectively explain how the Universe behaves on the largest of scales i. Unfortunately, these two theories are not consistent when it comes to a little matter known as gravity, which scientists are still unable to explain in terms of quantum mechanics.
