Dark Energy VS Dark Matter Dark Matter Dark Matter is the name given to mass that emits no detectable radiation. ‘’Dark Matter accounts for the galaxies rotating about "local groups" in tighter orbits than we expect from our observations. Gravity is stronger than we can account for unless there is some matter we cannot see. We are much more certain what dark matter is not than we are of what it is” (Feild‚ Ann‚ 2013).

The Nature of Dark Matter We observe the universe around us through many scientific means. However it is through the electromagnetic spectrum‚ that is everything from radio waves to gamma waves‚ that we learn about the objects in our world and beyond. However we can also learn about our universe through indirect means‚ such as the effect of gravity on light as well as larger objects like our galaxy.

the objects picture a description of what happens when light ray is shone on it. The source of light is a light bulb from a ray box. If a beam of light of one colour is shone through a prism‚ the direction of the beam is changed by the prism. This is because the two faces of the prism through which the light passes are not parallel. If white light is used the prism splits up the light into a series of colours. This shows that white light is actually made up of many other colours - a fact first

Why is Dark Chocolate Healthy?: Chocolate is made from plants‚ which means it contains many of the health benefits of dark vegetables. These benefits are from flavonoids‚ which act as antioxidants. Antioxidants protect the body from aging caused by free radicals‚ which can cause damage that leads to heart disease. Dark chocolate contains a large number of antioxidants (nearly 8 times the number found in strawberries). Flavonoids also help relax blood pressure through the production of nitric oxide
