I guess that would be quasars. A quasar is a small region in a young galaxy, that can emit perhaps 100 times the energy of an entire (present-day) galaxy. Quasars were a common feature in the early Universe. It is currently believed they were fueled by gigantic black holes.
the universe will continue to expand forever and ultimately most of the matter will be turned to heat energy.
Current theory states that it's "dark energy".
gravity is the most powerful force in the universe as it acts at great distances although its force is not as great as the weak nuclear force, the strong nuclear force or the electoromagnetic force
The universe is around 70% dark energy (a.k.a. empty space). The rest is mostly dark matter, with a few percent for ordinary matter. That is the current scientific model.
Hydrogen is the most abundant element in the universe.
Depends on how you define power. If we take it as transferring energy then it will have to be the most luminous. So the most luminous star known in the Universe is R136a1
He-Man might be the most powerful man in the universe and he definitely has the reputation of being very powerful. Superman is also considered to be one of the most powerful men in the universe, so this is a matter of some debate.
God, who created the universe.

most engery sources are derivded from the sun,s engery
there are many types of energy such as kinetic, elastic potential & magnetic but as you should know, energy is never the same, there is an infinite amount of energy in the universe but it never dies, only changes and there isn't necessarily a more powerful energy such as the core of the sun HAS more energy than the core of the earth which would make it more powerful yet this is only because there is more of it in the sun's core. energy would only be more powerful if you increase the ammount there.

The most common alternate energy sources (as alternates to to fossil energy sources, oil, gas, and coal) are : nuclear energy, wind energy, and solar energy.
The energy sources that I am most excited about all have lower carbon emissions, compared to conventional energy sources. These include Biomass Energy, Wind Energy, Solar Energy, Geothermal Energy, and Hydroelectric Energy sources.
The cosmic cube is the same as the teserract. They are both the 2nd most powerful thing in the universe. The most powerful being in the universe would be galactus because he is older than the universe itself and absorbs planets to give him even more power.
