Dark Energy is thought to be the energy that is causing the expansion of the universe. In 2003 Planck, a satellite which was set out to find out the answers to all the questions of Dark Energy, actually reported that ever since the Big Bang the universe has been expanding. They also found out that the amount of Dark Energy in our universe has been increasing over the last 13.8 billion years. This is bad as if it increases too much it could be the cause of the Fate of The Universe like explained below...
If the increasing amount of Dark Energy stops nothing really will happen if the universe stops expanding. There may be a risk thought to our universe. You see the dark energy (the expansion of the universe) is equal to amount of Gravitational Potential Energy in our universe. If the dark energy stays the same and the Gravitational Energy increases the universe will collapse on itself. Galaxies will crash. Planets will collide. This is the theory based on the fate of our universe called the Big Crunch.
But back to your question. If the dark energy levels rise over a critical level, the rate of the expansion of our universe will increase. This means that our universe will be expanding faster than ever. There is a theory called the Big Rip. So this means that the universe will be "ripped" apart. Despite the high levels of dark energy. Our universe will be ripped apart. Than galaxies within will move away from each other. Planets move away from each other so fast. Planets are ripped apart. Scientists reckon it may rip our bodies apart to. Than it comes to the atoms. The sub-atomic particles within a atom will be separated. So there we go that it one way our universe will end. There is also another theory about how our universe will end. This one depends on Dark Energy as well. The Big Freeze. Just like before due to the raising of the Dark Energy levels planet will be dragged away from each other and stars. Our earth, which 93 million miles from the sun might be pulled away from it. This means that with no heat and light source it will be too cold for us to live on this planet. The planet will freeze over and will become inhabitable.
So we have proof that the end of the universe is near.
You never know...
the universe will continue to expand forever and ultimately most of the matter will be turned to heat energy.
It would begin to collapse inwards towards its most massive points until finally it all met at one point, according to some theories.
Three different things happen to the solar energy that earth receives. Some escapes back into ____________, some is absorbed by land and water ____________________.
An open universe is a universe where all of the galaxies and stars and everything in the universe keep expanding with nothing stopping them. This theory says that the galaxies and stars will keep going further and further from the centre of the universe until everything dies off. This is the opposite of the closed universe theory where everything will expand, and then something will cause a turning point and everything will contract until everything there ever was will fit into a space the size of the dot at the end of this sentence. Then, possibly another 'Big Bang' will happen and start everything over again. :)
No one knows because it's 10 duotrigintillion is a googol or 10^100.
non spontaneous process happen in the universe but energy has to be provided to them . the free energy change of such processes are positive . the amount of temperature has to be increased to carry out such reactions
the universe will continue to expand forever and ultimately most of the matter will be turned to heat energy.
If water absorbs a large amount of energy it boils.
In my Universe, about 23% of its energy is found in dark matter -- about four to five times more than in matter we happen to understand. I don't know the percentage in your Universe.

In the first nanoseconds after the big bang there was only light energy in the universe. As the energy spread out and the universe cooled these photons of light energy decayed into a type of lepton called an electron. These are the most common types of lepton we can observe today.
If there was absolutely no energy in the universe, all matter would be completely still. The temperature would be 0 degrees Kelvin.
In this time, the high estimate for the time for the Universe to reach its final energy state, even in the presence of a false vacuum.
Nuclear energy is the energy in the nucleus, or core, of an atom. Atoms are tiny units that make up all matter in the universe. Energy is what holds the nucleus together. There is a huge amount of power in an atom's dense nucleus. Nuclear energy is seen when nuclear fusions or fissions happen.
There is no reason to believe that the Universe will be "destroyed" - it will continue expanding, and at some point there won't be enough free energy left to support any type of life, but the Universe itself will continue existing.
