dark matter and dark energy

By: Lian A.

It is about 20-25% of the total amount of matter in the universe

You cannot see the actual matter, although its effects are visible

It does not give off energy rays, so it is difficult to detect

Scientists know more about what dark matter is not, rather than what it actually is

It is about 70-99% of all energy in the universe

It does not posses qualities of “normal” energy (protons, neutrons, electrons)

It cannot be seen It is thought to be the force that is

causing the universe to expand Scientists know more about what

characteristics dark energy doesn’t have, instead of what is actually has

The pie chart on the previous slide shows the amount of dark matter and dark energy in the universe, although it might be inaccurate because it combines matter and energy into the same chart

Scientist had observed different areas in universe and noticed that there was an invisible force, that was doing strange things, without an explanation

They concluded that is must be a new type of matter and energy, which they latter called dark matter and dark energy
