No one knows exactly what dark energy is or where it comes from. Dark Energy is a new idea. Little is known about dark energy‚ yet it takes up a huge amount if the universe. Scientist were able to show the universe was expanding at an accelerated rate by measuring the red-shift of an object by comparing

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. In fact it is this indirect method of observation that has led us to the discovery of extra-solar

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). Scientists think dark matter is made of particles called WIMPS‚ "weakly

There is much more dark matter than normal (visible) matter in the universe. According to (this source) roughly 68% of the universe is dark energy. Dark matter makes up about 27%‚ while everything else in the universe (physical matter like the atoms that make up planets and stars) makes up less than 5% of the universe. According to (this source) the universe is actually 96% of dark matter and dark energy. With 73% being dark energy and 23% being dark matter but the implications of this
