The future of the universe is a topic of great interest and debate. What will happen in 100 trillion years? This is a difficult question to answer, as it is impossible to predict the future with any certainty. However, we can make some educated guesses based on current scientific understanding.
In 1014 (100 trillion) years from now, star formation will end, leaving all stellar objects in the form of degenerate remnants. This means that all stars will eventually run out of fuel and die, leaving behind only white dwarfs, neutron stars, and black holes. This will be the end of star formation in the universe, as there will be no more matter to form new stars.
The end of star formation will also mean the end of the universe as we know it. Without stars, there will be no more light, and the universe will become a dark and cold place. All galaxies will eventually be pulled apart by the expanding universe, leaving only isolated objects in a vast emptiness.
The fate of the universe after this point is uncertain. If protons do not decay, stellar-mass objects will disappear more slowly, making this era last longer. However, if protons do decay, the universe will eventually become a “proton soup”, where all matter is reduced to its most basic form.
It is also possible that the universe could eventually collapse in on itself, leading to a “Big Crunch”. This would be the end of the universe as we know it, as all matter would be crushed into a single point.
Another possibility is that the universe could expand forever, leading to a “Big Freeze”. In this scenario, the universe would become so large and cold that all matter would eventually become inert, leading to an eternal state of darkness and cold.
No matter what happens, it is clear that the universe will be a very different place in 100 trillion years. All stars will be gone, leaving only isolated objects in a vast emptiness. The fate of the universe beyond this point is uncertain, but one thing is certain: the universe will be a very different place in 100 trillion years.
It is difficult to imagine what the universe will be like in 100 trillion years, but it is certain that it will be a very different place than it is today. The end of star formation will mark the end of the universe as we know it, and the fate of the universe beyond this point is uncertain. No matter what happens, it is clear that the universe will be a very different place in 100 trillion years.
