Why is the sky blue?

Ever wondered why the sky was blue? If you have, find out here.


Hey guys, I’m back, I didn’t go anywhere, but I though it sounded a bit more dramatic. Anyway today’s question ‘why is the sky blue?’ Now this question is a very classic question that is ask by many young children and is probably not even known by most adults. Now to understand why the sky is blue, we first need to think about the light coming from the sun. Now most of us class the sun as a big ball of fire, and you’d be wrong it is actually a large compression reaction, attempting to make hydrogen into helium. I’m getting a bit off topic, but my point is that the sun doesn’t just produce red or orange light, like fire does, it in fact produces white light.

You may have seen the sun and be thinking “No when I look at the sun it looks orange, you dummy.” Yes you’re right, when you look at it, especially at sun set, it looks orange. But this is the point we will eventually lead onto, when light travels through space it contains all of the colours of  the spectrum: red, orange, yellow, green, blue, indigo and violet. You may also be thinking “Non of those look white” and the light spectrum is a question for another day.

Now just accept that all of those colours make up white light, but when the white light from the sun reaches our atmosphere, the light is scattered by the particles in the air and the blue part of the white light is what remains for us to see, thus making the sky blue. Then at sunset, the blue light is being dispersed above you and is out of your line of vision and you instead see the red and orange colours.

Thank you guys for reading and I hope you enjoyed, if you liked this post make sure you leave a like and follow for more answers. If you want me to write a post about the light spectrum and how it can be broken up, leave a comment and if you have any questions just message me in the contact page.

Why do we sound different on a recording?

Hey guys, it’s me, that guy, you know, the one that can’t type and took like 6 tries to type this sentence alone – yeah, that one. Anyway, enough of the long cliche openers, today’s question is; why do we sound different on a recording compared to when we hear ourselves normally? Well, it’s actually quite a simple answer and it’s to do with how we hear ourselves.

So, when we usually hear people we hear them through our ears, and that’s just basic knowledge, that’s what you know in preschool, but here’s the thing; we don’t hear ourselves through our ears. I know, mind blown. Anyway, the way that the sound from our vocal cords gets to our ear drum is through our skull, rather than the conventional way of our ear canal. What this does is it spreads out the sound waves and as the sound waves spread further apart the frequency lowers, meaning that you hear yourself in a deeper pitch as opposed to how someone else would hear you.

So that begs the qustion; what does that have to do with how we sound on a recording? Well, when you hear yourself on a recording, you hear your own voice through the conventional way of the ear canal, meaning that the sound waves don’t travel through the skull first, meaning that the pitch is raised compared to how you would usually hear yourself. Now, this is the reason that people don’t like the sound of their own voice:
1) Because men think they sound manly and deep voiced when they don’t…
2) You aren’t used to this voice and your brain doesn’t see it as being you so the unfamiliarity creates a natural opposition.

Thank you all for reading and I hoped you enjoyed and learned something new – like if you did enjoy this post, follow for more questions answered and message me if you have a question of your own.


Welcome note.

Hello and welcome to infinite knowledge!

This is the first post and this will just basically be an introduction to the site, so what will be on this site? Well, what i aim to do is find questions and answer them, then you can read them and then you have a deeper understanding of our world or universe. So what kind of questions will I be answering? I will be answering all kinds of questions the revolve around science and that will include: chemistry, biology and physics. I will not just answer the questions that I find, I will also answer questions that you guys have and if you have a question that you would like me to answer then send me a message at camtasia1802@gmail.com and I will answer your question. Thank you for reading and I hope you have a great day, until the next time.
