Can you find everything on the Internet?

Hi,
so over the last Sunday I have spent a LOT of time doing physics. This meant mainly analyzing the problem (which was the movement of rocket through the Solar System) and then ton of writing and rewriting but in particular researching on the internet. I had real trouble sometimes and spent countless minutes search information like “energy density of RP-1” which is a rocket propellant and how much energy you can get from it when you burn it.

This got me thinking about how the internet is spot where one can find basically anything but you should never forget that this makes it a huge dumpster.

Let me give you a very simple example that I can remember right now. Just type into Google “Sun”, I did this because I wanted to know the radius of Sun [1]. The first link will probably be www.thesun.co.uk that is British magazine as you might already know (and a bit controversial as you might find out when you click on the link). Of course, I did not want to know how some celebrity’s kid spilled soup so I clicked the second one (which was Wiki). What I simply wanted to illustrate is that internet will give you what you ask for, except that you do not know what you are really asking for. The most visited webpages are made for quick eyes, simply who sets the best clickbait gets to the top so it is going to be difficult to get some hardcore explanation of a given problem. This is partially the reason why I wanted (and luckily got) a textbook for astronomy. I realized that it is no longer an option for me to learn from the internet (as I knew it back then) and decided that I need solid source of information [2]. So yes, internet will quickly give you the video about biggest black holes but you won’t know why they are so big. After you type in the exact question you might at best get binary answer (this one is a trick, if I remember correctly we do not know how come supermassive black holes be so big). In short, internet does not go deep, just check out channels like SciShow for example. You need to spent way more time digging in this dump if you gonna find anything. It also helps to understand what you are looking for, because internet is not best in explaining.

[1]You would not believe how tricky it is to find if this is the same information as the radius of the surface of the Sun (and it is).

[2] It is possible of course, you just have to do way more work.
