Your channel deserves so many more subs than it has. To think about some of the channels with 20+ million subscribers ... they contribute to this world less than 1% of what your videos do.
I don't know how I ever made it to 68 years old and never took an astronomy class, especially since as an airline pilot I was always interested in the subject. Really excellent, clear teaching, looking forward to going through this series of videos...
Michael thanks so much for the knowledge that you are sharing, if the earth were about to get destroyed, i would rescue the beatles discography, few paintings and your youtube channel, thanks again
hi, i love astronomy and these videos help me understand- actual astronomy. i figure a lot of people think it is just the photos of space, but it’s more math and calculations.
I've never been any good at science but I always found it very interesting so I thought I'd give these a watch, I'm beginning to understand science now thankyou!
I thought I had seen things, yet I find your explanations fascinating, it peaks the curiosity in me of wonder. Thank you Michael, you are truly great teacher. Edit: Grammar
"Raises hand" Mr.Biezen, you spoke of Hydrogen making 75% of the universe and the other 25% is Helium but then you said that it isnt the totality of the universe that there is a 1% in the universe, that makes up the whole periodic table, so does that mean that Helium makes up like 24% or Hydrogen makes up 74%.... or something? "puts hand down... waitsss ._."
+Roberto OnTheMoon The 75% and the 25% are just approximate numbers. The exact amount is lower for both and the rest of the elements on the periodic table make up about 1-2% of the total.
Professor, wouldn't it be more accurate to say that 0:19 Hydrogen makes up about 75% of the "observable" universe? We don't know what is out there or even if the universe is infinite or not. Whatever the case, is this what you mean when you say "the whole universe"?
It is true that the part of the universe that we can't see is probably much bigger than the part that we can see, but it is assumed that the consistnecy of the existence of hydrogen and helium is the same everywhere in the universe.
Mr Biezen, is it true that higgs field is responsible to give only 1% of the atoms's mass while the rest of it is in the form of kinetic energy? and....the solid shell made up of incredibly fast electrons you talked about,,,,is there a shell made by each individual electron in an atom?
Note that the Higgs field is a theory that tries to explain the concept of mass and gravity. It is just a theory and far from proven to be correct. The shells (or orbitals) formed by electrons can house 2 electrons each as long as they have opposite spins when they occupy the same orbital. The energy levels and orbits of electrons becomes very complicated very quickly when considering multi-electron structure.
Electrons are physical entities that have essentially a point mass. The probability comes in when you try to describe the LOCATION that they are at. What is the probability they are momentarily at one position versus anywhere else. In the case of a hydrogen atom they have an equal probability to be at any angle a radial distance away from the nucleus.
"Matter dominate" is just a term somebody threw out once to imply that the radiation is space could not freely travel through the universe. The term stuck and we are still using it.
Mr. Professor I have heard that it is possible to make Au from Hg through nuclear reaction. Since it is energetically demand reaction and the product is radioactive it is not common. Does Gold from space is also radioactive?
Theoretically it is possible to make gold from mercury by removing 1 proton from the nucleus, but that is extermely difficult to do and is not practical at any sort of quantity. Both mercury and gold are very stable.
Well ... the electrons are not really "rotating" around its nucleus, because it would radiate energy, would'nt it? ... is'nt that the reason for the birth of the so called spheres-model or electron "clouds" around its nucelus? ...
Revolving would be a better word, but they do indeed circle the nucleus an incredible number of times every second (and they do not radiate energy because of their orbital motion).
If electrons stopped rotating and collided with the nucleus, would it simply annihilate itself and create energy, as in the case with matter and antimatter?
hmata3, No, but it would be the end of matter and the Universe. Combining positive and negative particles is not the same as combining matter and anti-matter.
The size of the Moon depends upon it's composition/it's density in relation to the Sun AND what is the Earth. Importantly, on balance, the rotation of WHAT IS THE MOON matches the revolution. By Frank Martin DiMeglio
Per the prevailing theory, the Moon was formed when a large object impacted the Earth more than 4 billion years ago. The mass of the Moon is about 1/80 the mass of the Earth.
@@ishathakur115 Much like oil floating on top of water, gaseous hydrogen and helium have very little density in comparison to the other components of our atmosphere and as such, have a strong tendency to move up and out of our atmosphere once they are released. The vast majority of gaseous helium that we do have here on earth was created from radioactive decay deep underground, and can become subsequently trapped in oil and natural gas deposits. When these deposits are mined, the helium can be isolated and captured.

Welcome to our channel! Astronomy is a fascinating topic and as an airline pilot you will really be able to appreciate it. 🙂
This channel is soo underrated. Good work!
This guy really is a talented lecturer. Thanks!
Thank you. We are glad you like the videos.
Michael thanks so much for the knowledge that you are sharing, if the earth were about to get destroyed, i would rescue the beatles discography, few paintings and your youtube channel, thanks again
Haha, that was funny! I agree with the Beatles.

Astronomy is VERY interesting.

Great! You will find a lot of videos on our channel that does not require an indebt knowledge of math. Enjoy! 🙂
Hi ,in which class now you are studying
Amazingly clear lecture
I thought I had seen things, yet I find your explanations fascinating, it peaks the curiosity in me of wonder. Thank you Michael, you are truly great teacher.
Edit: Grammar
I dont know how I get here but I dont regret it at all! Super interesting and its a good addition to all the stuff school teaches you.
Glad you enjoy it!
I really appreciate your approach. THANK YOU!!!!
Glad you liked it! 🙂
Thank you. It is amazing.
I'm planning to be a part of NASA someday. This really helps my knowledge about astronomy. Thanks!
Knowing astronomy well is definitely useful when working with NASA.

+Roberto OnTheMoon he meant 99.99% but just wrote 75%+25%
Thank you for clearing my 5 year old doubt. The doubt kept me uneasy throughout the years.
Thanks for sharing your knowledge sir.❤ respect from India..
Welcome to the channel
This was class!MICHAEL
Wonderful Lecture. Thank you So Much
Thank you for your kind words.
Thanks Michel! great video!

I thought electrons were a probability cloud. Do probability clouds zip?
Electrons are physical entities that have essentially a point mass. The probability comes in when you try to describe the LOCATION that they are at. What is the probability they are momentarily at one position versus anywhere else. In the case of a hydrogen atom they have an equal probability to be at any angle a radial distance away from the nucleus.
@@MichelvanBiezen Thanks for your reply. I am very happy to have found your channel.
I have one doubt: when the big bang took place every subatomic particle, matter, anti matter, etc. was in a tiny point but how did matter dominate?
"Matter dominate" is just a term somebody threw out once to imply that the radiation is space could not freely travel through the universe. The term stuck and we are still using it.

Love your videos! But the audio definitely needs to run through a limiter before uploading.
Make a video on how to build a satellite
That would be an interesting topic indeed.

Fact is since the whole universe is made of hydrogen and helium but these elements are not found on the earth
We have lots of hydrogen on the Earth. (The oceans and your body are full of hydrogen)
Not As gases ☺☺ right!
sir u are amazing
Where the hell did you get that from ?

I wonder if alien alchemists tried to turn gold into lead if the abundance of each on their planet was reversed o.o
They would have come to realize that it was impossible for them like it is impossible for us.

BBDNuh yes, you won’t remain Muslim and believing in god
No problem.
