After about another five billion years, the sun will burn out, and the process of nuclear fusion that has kept the force of gravity from collapsing it will cease to be powerful enough to counter it. The sun will then collapse into a White Dwarf, which is an incredibly dense and comparatively small piece of matter. The white dwarf, will, eventually, cool down into a small, black, non-radiant, cold cinder. The white dwarf is actually extremely dense, with one piece the size of a matchbox weighing in at the same weight as a full-grown African elephant.
The first Law of Thermodynamics states that energy can be changed form one form to another, but it cannot be created or destroyed, and the total amount of energy and matter in the universe remains the same, simply being changed from one form to another, so all the energy in the universe will exist into infinity, only changing into different forms.
If there was absolutely no energy in the universe, all matter would be completely still. The temperature would be 0 degrees Kelvin.
All form of energy would eventually convert to heat, largest heat sink in the universe is space. Earth continue losing heat to space by radiation heat transfer. Absolute temperature of space is slightly higher than 0 K.
Completely false. By the law of entropy all energy sources eventually run out as they disperse it evenly over the universe. No energy source is inexhaustible.
Practically ALL electrical energy eventually winds up in the form of heat energy.A toaster is one device that's DESIGNED to make that happen, in the place andtime that we want it to happen.
yes
The useful energy will be gone eventually, one way or another. As a result of the Second Law of Thermodynamics, it is unavoidable that we will eventually run out of useful energy.
Eventually all the stars in the universe will extinguish and go supernova, and the universe will become dark. With no light or energy the universe will become a cold and dark place, but alas, there's no reason to start selling all your stuff and preparing for Armageddon as this will take billions and billions of years to happen. Our own Sun will continue to burn strong for about another 7-8 billion years.

A description of the universe includes all matter and energy.
The universe is defined as everything - all space, all time, all matter and energy.

The Universe.

All the energy that is now in the Universe was there since the time the Universe started - that is, since the Big Bang.
