What Is the Difference Between Galaxies and the Universe? The terms universe and galaxy share one common point, they are both terms related to space. Beyond this however the key difference between the two can be compounded by considering a galaxy as an apple and the universe as a fruit bowl. Basically galaxies are part of the universe.
How Big is Betelgeuse Compared to the Sun? Betelgeuse, like the other stars mentioned above, is among the biggest stars in our Universe that we know of at least. This supergiant red star has between 950 and 1,200 solar radii, or it has between 95.000% and 120.000% of our Sun’s radius.
The Big Bang theory states that the early universe was a hot place that expanded, and began to cool down. This means that the universe should be filled with radiation which is actually the relic/leftovers of the Big Bang event.
So how many galaxies are there in the Universe? Currently, the observable Universe, which has a radius of 46.5 billion light-years, seems to contain at least two trillion galaxies. Our galaxy, the Milky Way, is just one among these numerous galaxies, and it isn’t even considered a big galaxy.
Who knows, maybe in a parallel Universe, Jupiter ended up being the only star in our Solar System, and the Sun might have become a gas giant instead. Is Jupiter Bigger than our Sun? Jupiter may indeed be the biggest planet in our Solar System, but is it bigger than our Sun? No, the gas giant pales in comparison to our Sun.
The universe then theoretically is space so it expands in size but not into any finite empty space it is looking to fill. Where Did the Big Bang Occur? So we come to the big question: is there a place in our universe that can be called the point at which the Big Bang occurred?
Our universe is vast and ever expanding which begs the question “where is its center?” In this article we are going to take a closer look at how our universe came into existence and try to answer the question: where is the center of the universe? It Started With the Big Bang? Science suggests that our universe as we know it started with an event dubbed the Big Bang but what exactly was ...
