Answer:
<em>Dark matter and dark energy</em>
<em></em>
Explanation:
Dark matter is thought to make up about 85% of the mass-density make up the universe. Dark matters have not been observed by direct interaction, but indirectly by their interaction with the universe generally; producing some gravity effect that cannot be explained by the existing gravity laws except there is more matter in the universe than is accounted for. Dark energy is an unknown, and undetected energy that is thought to exist in the universe, and affects the universe on the largest scale. The existence of dark energy is the only explanation for why the universe is seen to be expanding at an accelerated rate, rather than at a constant rate. <em>These two element (dark matter and dark energy) make up a very large energy-mass portion of the observable universe.</em>

Although the League of Nations was much of the work of President Woodrow Wilson America never joined the League of Nations.
This was for several reasons, firstly America had suffered civilian casualties in the war, and many people in the USA wanted to keep America out of European affairs.
This policy was called isolationism and was probably the main reason that America didn't join the League.
Also joining the league meant that this might involve having to do things that might set back the economy or damage America otherwise.
For instance sending out soldiers out to other parts of the globe would be a very costly venture and there would probably be casualties as well.
There was also the fact that America had had little involvement in the war and had some civilians (especially German immigrants) also had little or no support for British or French policies and/or the Treaty of Versailles.
So although when the League was actually being formed Woodrow Wilson still backed America joining it, by this time America had had enough of wars and dealing with other countries problems and, despite Wilson America never joined the League.
