NOTICE: This is my opinion and I've been doing research on this topic (no not for school, just for this.)
This is a tough topic to look up, as there's so many theories, like flat earth, universe being a hologram, etc. I am not sure what is true, as there are many theories, but yeah there's a lot of evidence showing that the universe is real, but I wouldn't believe everything you read or hear, even if it is from the Government. Even though there's a lot of evidence about the universe being real, there's also lot's of evidence that the Government is messing with us, that the Universe is a simulation. There's this interesting quote I found on theguardian.com (link to the website I found will be below all the text). Here's what it says: “Even things that we think of as continuous – time, energy, space, volume – all have a finite limit to their size. If that’s the case, then our universe is both computable and finite. Those properties allow the universe to be simulated,”-Rich Terrile.
There's lot's of controversy saying that we live on a flat earth or that the universe doesn't exist. I don't know which one is really true, no one does (except, probably the Government.). Let's take a ride to an a Astronomer's point of view of the universe. Why would Astronomers do research and find out what these 'new planets' are made of if any of this isn't real. Well of course Astronomers get paid to do what they are doing. The average astronomer gets paid $104,100 per year, but the lowest astronomer pay is around $52,460 and can go up to $166,320. So they might do it just because of the money, it looks like it pays well. I kinda believe that the universe is real, because I want to think there's something out there, beyond our world. Some say the people who believe the universe is a simulation can just redo the universe's perimeter and be always correct, but that isn't true Science. If the universe isn't truly real, then atoms, elements can't be true.. Or can they?
I believe that there's something out their, but yet, there may not be. What do you think?
