Will the Universe Expand Forever?
The universe’s future depends on a fight between things pushing it apart and things pulling it together. Imagine the universe is like a balloon being blown up or deflated. How fast it expands is measured by something called the Hubble Constant, and how much it wants to collapse is due to how much stuff is inside pulling on it. If there is not much pressure pushing out from the stuff inside, then what really matters is how much stuff there is. If there is not a lot of stuff, the universe will keep on expanding forever. But if there is a lot of stuff, it will eventually pull the universe back in on itself, like a collapsing bubble, called the “Big Crunch”.
However, scientists have found that the universe’s expansion is actually getting faster, not slower. This suggests there is something weird out there, something with a kind of anti-gravity effect, like a mysterious force pushing things apart. They call it “dark energy”. If dark energy is a big player, then the universe will likely keep expanding forever.
Origin of Universe : Big Bang theory & Current Cosmology
Origin of Universe: The story of how our universe began starts with a big event called the Big Bang theory. According to the Big Bang theory, everything began from a tiny and super hot point. From there, everything expanded fast by creating atoms. Most of the stuff in the universe is made of hydrogen, about 74% of it. This expansion has been happening for about 13.8 billion years, and now it seems like it is getting faster. However, some people disagree with the Big Bang theory.
They say it is based on the wrong idea that the universe is always expanding. They believe the universe is just staying the same which implies the early thoughts of Einstein. Later on, Einstein realized that the universe was getting bigger, but he had to change his theory to fit that idea. Our Solar System is a galaxy that is called the Milky Way. It has eight planets, including Earth, that go around the Sun. Besides the planets, there are also smaller things like asteroids, meteoroids, and comets flying around.
In this article, we are going to discuss the origin of the universe in detail. Let’s explore.
