Now, for a random thought, 'End of the world', or as its popular title, 'The Fate of the Universe'. How will things go? It has been said that the Earth can end several different ways.
One being the 'Big Freeze'. Most likely, the definition of the 'Big Freeze' is that the universe will continue to expand forever. As it expands, the universe will cool and eventually be too cold to sustain life.
The other possible scenario for the ultimate fate of the universe being the 'Big Crunch'. You know how I said that the universe will most likely expand? Well, this scenario is different. Basically the expansion of space will eventually reverse and the universe will re-collapses on itself, ultimately ending as a black hole singularity.
Another scenario for the fate of the universe is called the 'Big Rip'. This reminds me of the 'Big Freeze' but worse! This hypothesis was first published in 2003, in which, the matter of the universe, from stars, atoms, subatomic particles, and galaxies, are progressively torn apart because of the expansion of the universe for this to be possible, this hypothesis relies on the dark energy of the universe.
The final possible fate of the universe that I could find is the 'Heat Death' of the universe. This is the definition on the internet: 'The idea of heat death stems from the second law of thermodynamics, which states that entropy tends to increase in an isolated system. If the universe lasts for a sufficient time, it will asymptotically approach a state where all energy is evenly distributed. In other words, in nature there is a tendency to the dissipation (energy loss) of mechanical energy (motion); hence, by extrapolation, there exists the view that the mechanical movement of the universe will run down in time due to the second law.' I agree with this definition of the hypothesis. My other thought of the 'Heat Death' is that, when the Sun dies (in about 5 billion years) it will engulf all of the inner planets, up to the asteroid belt. And everything will burn up and explode.
Out of all of these scenarios of the possible fate of the universe, I believe the 'Big Freeze' is the one that will kill us all. Unless, in 5 billion years our Sun kills us first...
Very interesting topic to think about.
By the way. I added a page about me. . .
