Have you ever wondered how the James Webb Telescope could take a photo that's 13 billion years old? Or how light can reveal secrets from billions of years ago? In this video, I'm exploring the fascinating concept of the Doppler effect as it applies to light, known as redshift. By understanding redshift, and the expanding universe, scientists can peer almost 13.6 billion years into the past, observing the universe when it was just 2% of its current age.
I'll also be giving away an awesome Space Shuttle Lego set, so be sure to stick around until the end of the video to learn more about how you can win! Enter to win at the link below.

Do you think there is life out there? - Shoutout to KiwiCo for making this vid possible, check them out here: www.kiwico.com/primalspace
life is almost certainly out there, however it is likley only simle organisms and no complex life there
I know for a fact there are other lifeforms out there. There was even life on other planets in our own solar system millions of years ago. I have an image taken by the curiosity rover when it was in the Gale crater on Mars of a large reptile's fossilized remains. The wild thing is NASA employees know of it too because the Curiosity rover took a rock sample of one of it's fossilized vertebras and found it contained organic compounds. Indicating it was once a living breathing creature. It should have been front page news but they kept silent. I believe it's because they wanted to go back to Mars. I believe if they had proof the red planet once contained life there would be no other reason to fund future missions. Mystery solved. But, as long as there's a mystery to be solved there will be future grants available for more studies.
That's why so much funding goes to looking for dark matter and dark energy. They are the biggest mysteries to date that need solving. I believe they don't really want to solve them mysteries either. Well, as long as the money flows to them they'll keep dodging the solution. I solved the dark matter and dark energy mysteries many years ago. Wrote and published several books about them. I know they're dodging the solutions because it wasn't that difficult to figure them out.
i think there is definitely life out there but only stuff like bacteria because complex life is just too rare because of how many steps it has to go through.
Yes, tho it wont be very similar to us humans. They will be different to us depending on what kind of environment they live in, even possibly what kind of technology have they discovered. And their intelligence may also be different depending on their genes/evolutions. in simple words, they do exist but their appearances are adapted from their own environment. As well as their intelligence are merelt based off their genes.
If the universe is continuously expanding, there must be a spherically solid wall surrounding it. And how thick is the wall? There must be space outside this wall and another wall containing the space and so on?
Knowing there could potentially be life in those far away galaxies and that we could do nothing to stop them from moving away due to space's expansion just feels terrifying to me
Those are old sparse galaxies that probably don’t house much
The possibility of my sewer backing up terrifies me. I'm cant concern myself too much with potential aliens moving away in the distance. In fact, that might be their preferred motion,.
@@nopenope7088 why tho?
Good thing they are moving away.
If they come to know of the character of earth beings, they may speed up further
I think the quote by Arthur C. Clarke sums it up nicely.
“Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.”
A great quote no doubt.
That was an amazing and really easy to understand explanation of Redshift. Keep up the great work!👍
Agree. This was an excellent explanation.
Can't wait for the James Web telescope to capture a million year old image of an alien flying by. That would be amazing.
For this james web need to smoke weed
Even if it would, they will not show us.
It will not be made public
@@Prakhar_Pandey true
@@lukeblignaut2445 btw what you said is so exciting to imagine
@@Prakhar_Pandey Why not? as long as the alien is several million/billion miles away, I don't see why anyone would panic and not release it to the public
James Web's discoveries are getting amazing day by day, the hard work of the scientist involved in this project has really paid off and thank you for the great explanation of expansion of universe and Redshift. 😃👏
the idea of life potentially being somewhere in this universe is scary but exciting. seeing what other creatures are like and how they could be completely different seems extremally fascinating
Space is so cool to me, I’ve loved the thought that at one point in space you are far enough from earth you could see the exact moment the chicxulub meteor wiped out the dinosaurs, or you could go back and see the vesuvius eruption at Pompeii, space is so big that distance can become a sort of time travel
Strangely terrifying. But if you think about it, it's better to have a universe expanding outward than collapsing inward.
Less scary albeit irrelevant
Good Point
I think that there is definitely life in our universe. The universe is big, very big and there are so many galaxies out there, so many possibilities. Life is not something that only happens once, it happens because of certain conditions being present and since the universe is so huge, there definitely is a chance of life happening in other planets. They (beings of other worlds) might be far away, young or dumb but there always is space for more life in the universe other than us.
Also love the video ❤, very nice graphics and animation as well as helping me understand complex topics about light and our universe.
Thanks for reading my comment 🙃
Thank you so much for sharing your thoughts on the topic and so glad to hear you enjoyed the video. It really means a lot! Good luck in the giveaway!
It is absolutely mesmerizing just how enormous is the universe we live in. There is literally no way to wrap our heads around these vast distances and space. So big, yet appears so lonely.
This is easily the best deep space video I’ve seen where I’ve actually learnt something completely new.
For some reason, I've been more fascinated with these topics more and more lately. This video has done a fantastic job of visualizing and explaining the physics of our universe in a simplified way. Thanks!
I really love your channel and the way you explain. I always watch with my nine year old son, he finds it very entertaining and easy to understand. Keep up the good work. :)
Your boy is really smart. I was considered smart at a young age but wouldn't be able to understand this video at 9 years old.
I love JWST videos, its incredible the amount of things its capable of. Hyped about all the things it will teach us.
This video deeply satisfied my curiosity about space... and the simplicity with which you explained everything us truely remarkable. I wish could've found this channel before, but better late than never. Thanks!
Thank you so much! I'm so glad you've found the channel now and that you enjoyed my explanation in this video. Welcome to the Primal Space community!
Not only is life definitely out there, the universe is so inconceivably large that there is potentially another you doing the exact same thing you're doing at the exact same 'time.'
Pretty mind blowing and amazing to think about. Thank you for sharing your thoughts and good luck in the giveaway!
Hey Primal, brilliant video as always, can I also mention recently The Telegraph Newspaper did an article about a new NASA rocket which will cut journey time to Mars in half. I think this would be an interesting topic to cover, especially because you're able to explain in a way us non-techical people can understand, the cookie explenation was 👌. 😅❤
An incredible way to explain the sheer inevitability of life on other planets
Thank you so much. Really glad you enjoyed the video 🙏
The James Webb telescope videos are probably the best ones since there is so much to learn about the way the engineers designed it. Truly remarkable!
Agreed! So much to learn and I enjoy making them just as much! So glad you're enjoying the content! Cheers!
Sure there is a live not only on Earth. So much still uncovered in our universe!
I think life has got to exist. The universe is so big and old. I just might be so far away that we’ll never contact it :(
In my opinion there is definitely life in our universe. The universe is so big that there is a chance for anything to happen twice, including life.
Also love the video, keep up the amazing work ❤
Love that perspective. Thank you for sharing and so glad you enjoyed the video. Good luck in the giveaway.
The question of whether life exists beyond Earth is one of the most intriguing and enduring mysteries in science and philosophy, but I think there is life out there somewhere we can't be alone in this universe.
I tend to agree with you. Thank you for sharing your thoughts and good luck in the giveaway!
The idea of life existing beyond our world is a fascinating reminder of the endless mysteries waiting to be explored in the vastness of space.
Doppler effect is crazy, thanks for explaining in a simple way for me to understand 😊
I'm pretty sure there is life in our universe. I mean, the universe is huge there as to be someone else out there
I mean the only real quastion is if we will ever whitness advanced alien lifeforms, not so much if they exist or not
That's basing on hope, not evidence.
There COULD be, there doesn't HAVE to be.
Thank you for sharing your thoughts and so glad you enjoyed my explanation! Good luck in the giveaway 😊
The evolution of life on Earth from non-living matter to humans is a staggering feat with odds of 1 in a billion. And yet, we are still searching for life on other planets. This makes me believe that there must be some form of life beginning, ending, or growing somewhere in this vast and expanding universe.
When you zoom in on DNA, you realize that life is nothing more than complex physics and the nature of the universe. life is a product of the laws of physics and the forces that govern the universe. while it is true that DNA is made up of molecules that are governed by the laws of physics, life is also a product of evolution. Therefore, it is not accurate that life is "nothing more" than complex physics.
I’ve been told multiple times that life is extremely rare and we are lucky but considering how big the universe, there must life somewhere.
I tend to agree. Thank you for sharing your thoughts and good luck in the giveaway
@@primalspace thank you 😊
There's so much an average person would never know if not for videos like this. The explanation of how the galaxies are moving away from every other is fascinating.
Thanks and keep making informative videos like this.
Thank you so much! I'm really glad to hear that you enjoy my explanations - it really means a lot!
I'm truly fascinated by how the basic principles of physics can lead to such incredible discoveries. It's truly remarkable how something so simple can unlock so much potential.
Life in our universe would be amazing and scary at the same time because it would spark so much curiosity and fear. Like what are they like? Are they violent? Do they know about us?
Wow!! Just wow! The amount of information is just mind blowing and can not imagine the effort that goes into making these awesome videos!! ❤️
Thank you so much! It really means a lot that you enjoy the content here on my channel. Cheers and thanks for watching!
Hats off to the engineers behind James webb Telescope. Its an engineering marvel
Absolutely
Lol I just got the shuttle lego set last month. It was so cool growing up in Houston and seeing the shuttle flying atop the 747 buzzing around all the time.
For us the photon did travel for 13 Billion Years, but the photon itself just started its voyage recently, if it had a perception of time.
i think how much technology has evolved we could soon be able to create sustainable living spaces on places like mars and even discover other habitable planets in other galaxies! love these vids keep it up!!!
Just a small criticism on oversimplified assumptions with respective corrections in this awesome video:
1. We [DON'T] know the expansion rate of the universe yet.
2. We [DON'T] know if the Hubble constant is constant.
3. We [DON'T] know it's inevitable to have life out there.
I don't wish to diminish the content, just being balanced on these important affirmations.
This video is so underrated. This was beautifully crafted to visualize how the universe is expanding. The more I learn about space the crazier it gets 🤯 truly fascinating
Thank you so much! I'm so glad you enjoyed the video 💙 It really means a lot!
I've heard of space expanding between objects, but I guess I have never understood how. Thanks for the informative video, I know understand how the universe expands!
So glad you enjoyed the video!
I really appreciate with your explanation. Every video is full with emerging information.
Thank you so much! I'm so glad you enjoy my videos and explanations! It really means a lot!
It gives me a sense of relief that the chance of life in the universe is high. If we mess up there might still be someone else who can appreciate life
So true.
When I was a child I was dreaming about seeing through the space to the deepest parts of it to see whats actually there - now it's possible thanks to Webb telescope! Dreams come true :)
So true! Love this!
Great video, very well explained. Thanks for taking the time to teach laypeople like me! I a huge space geek, who thought I generally knew what redshift was, but clearly did not. Your video did a great job of showing me. I wonder what else I don't know! (nobody answer, lol) Thanks again!
I think if space is that big, there somewhere must be life. This was amazing videos as always! Great explaining. Keep what you doing!
Thank you so much! So glad you enjoyed the video and my explanation. And thanks for sharing your thoughts - good luck in the giveaway!
you never know whats out there could be a huge star about the size of our galxy ,ships that travel the speed of light ,invisible galxys, habital worlds
Love the channel and thanks for making the rocket science a little easier to comprehend. Much appreciated.
It’s incredible how much work has gone into JWST. Truly some of the most cutting edge technology humans have ever applied.
It's crazy that we are now finding out that the rate isn't the same anymore and we are now looking for a center thanks to James Webb. Insane.
it amazes me how simple physics phenomena are used to make such amazing discoveries, truly remarkable!
💯💯💯
Thank you so much !!!
The way you explain things makes them so easy to understand.
Greetings from France
Thank you so much! I'm so glad that you enjoy my explanations! It really means a lot 🙏
We are developing things so much that I think in the future we will have a telescope that can see different galaxies in HD quality.
Love the thought of this!
Wonderful video explaining the redshift in the most simplest manner.
Life is like a cosmic mystery somewhere in the vastness of the universe just waiting to be discovered in the most unexpected places.
“We are also giving away this lego space shuttle”
Me who already has one built complete: nah I don’t need it
I just can't say how much this channel helped me know more about space,,,,,,,,,,,,& also making me more interested in space!
Thank you so much! I'm so glad you've been enjoying my content! It really means a lot! 🙏
animations are getting even better. Great work mate
Thanks so much! Really glad you're enjoying them!
One of the best (short) explanation of redshift here on youtube.
Thank you so much. That really means a lot! 🙏
Since I find myself here and now, having to my memory skipped most of the existence of the universe so far, it seems entirely plausible that there would be other life.
Hullo! Great video as always!
I had a few questions:
- first, Is the wavelength used to compare the redshifted one coming from a specific source, or is it just any wavelength for reference.
- secondly, what exactly is being stretched in our universe? Is it matter (ie the space between atoms) or is it in fact in the void, the absence of matter (which I assume would make more sense?)
Thanks for your replies, keep up the amazing content!
Ps: I am certain there is life out there, I just hope it is in our reach so we can meet it one day
It's not matter. The "space between atoms" is held together with greater force than the expansion of space. In fact, even the very very weak gravitational "force" is stronger in some places than that, which is why galaxy clusters can stay together and even individual galaxies still attract one another eg Andomoda and the Milky Way.
Amazing insight on the topic, loved it as usual 🙌
Thank you so much! So glad that you enjoyed it!
I'm just curious to what life could look like on other planets, so far we only got 1 example and it already has some of the weirdest things you can imagine
What amazes me is how people discard the fact that we still don't know if it is infinitely big or just extremely big. If it is infinitely big, then it can be implied that there is also an infinite number of planets that potentially hold life. The variations in each form of life can range from being very similar to completely different, which for me is mind-boggling. Additionally, I find it unsettling that as a species, we are not advanced enough to thoroughly explore and engage with other potential life forms before they vanish into uncharted territories.
I love your videos so much. They are very clear to understand.... And my favourite was about jame webb and voyager 2
Thank you so much! So glad you've been enjoying my videos and explanations. It really means a lot! 💙🙏
Cosmic mysteries and the question of whether we are alone in space have always stimulated the human imagination. Maybe someday we will find out if we have space neighbors or if we are a lonely island in the ocean of the universe. It's both interesting and frightening at the same time.
Agreed!
Great video with excellent animation! 🙌
I think that it is very probable that life exist somewhere else than on earth but I also think that it's not probable that we will get in contact any time soon or ever. I mean the civilisation or even humanity has just existed for a glimpse on the timescale of the universe and the region of space that could detect our presence is very limited. Also, I like to think that other forms of life would be so different, that we would'nt even identify as such, considering that we already struggle to find a definition to life itself.
Thank you for the video. It's interesting and very easy to understand for most of us. Life maybe out there, yet in a form we could never imagine
Thank you so much! I'm so glad that you enjoyed my explanation. Really means a lot!
Loved your straight forward explanation. Subscribed.
Thank you so much! Really means a lot that you enjoyed my explanation. Welcome to the community!
i feel like its like the problem which came first the chicken or the egg. there is a definitive answer to everything in the universe but we don't have enough knowledge/advancements to get to that answer
I am very intrigued by the idea that there would be advanced life in similar conditions as on land, but underwater. After all, one of the breakthroughs for man was fire, so it would certainly be fascinating to find out how they evolved.
The technology and science involved is so incredible
Truly mind boggling stuff!
It amazed me how brilliant human minds are to observe and harness even the most subtle clues to discover how magnificent the universe is and small we are.
Agreed!
Love this kind of content, keep up the great work!
Dman, this is one of the best videos on this channel. Well done mate =)
Thank you so much! So glad you enjoyed it. It really means a lot!
I think life definitely exists, but most people forget that this life could easily be very small and thus even harder for us to find.
it is really fascinating to think or if we can finally find of another life in our (gigantic) universe
Very Well Done! Interesting and understandable and well-paced. Thank You!
Thank you so much. I'm so glad you enjoyed the video!
Life is like, you know, this crazy roller coaster ride, man. It's like, you never really know what's gonna happen next, and it can be totally mind-blowing, right? Sometimes, it's all fun and games, and other times, it's like, a total bummer. But hey, we gotta keep pushing through, learning, and figuring stuff out, because that's what it's all about, bro. And, like, connecting with people and finding those good vibes, man, that's where the real magic happens. So, yeah, life's a wild journey
What is most shocking about all this is just what we can't see, and will never see. We talk about if there's life on mars, but looking at the sheer scale of the universe we can't even see, it seems completely inevitable that life exists somewhere out there
knowing that the galaxies that are further from us are getting even farther is scary as it is lowering the probably of finding life elsewhere.
BTW love your videos.
This is a great video and this is my first time watching your channel, it's entertaining and easy to understand
Thank you so much! So glad that you enjoyed the video. Welcome to the community!
So cool to see how scientists use the most minute differences in readings of a couple pixels in a photo to find out so much information about our universe.
I just love the universe because there are so many things to explore and there may be parallel universes.................Love your videos
Love this and thank you so much! So glad you enjoyed the video!
wow, your animation technique is cool
and finding life in the dots we see is something else...
I just love how this guy explains stuff. Makes science easier to understand
Thank you so much! It really means a lot that you enjoy my explanations 💙🙏
@@primalspace are you kidding. I subscribed right away. I'll be watching as many videos as I can every day from here
It’s definitely a possibility that life is out there in those far away galaxies is scary. But luckily as said in the video, everything is moving with the expansion of the universe. Space is amazing and also so scary.
The possibility of life formation anywhere in the universe is super low entropy. However if space is infinate, then the possibility gets greater and greater. We are evidence that life can exist, so even if in a form of bacteria, statistically life should exist somewhere in universe as well
amazing videao! its crazy to think there is life existing out there, what is more interesting is are they not developed enough to reach us or developed enough to not wanna reach us !!!
For sure! Mind blowing no matter which way you think of it! So glad you enjoyed the video and good luck in the giveaway!
How good is your explnation and graphics
It makes subject easy to understand and Logical
I got the red shift concept in the first time
like how the we see strected wave and all
Thank you so much. I'm so glad that you enjoyed the video and my explanation. It really means a lot!
The fact we have engineering and science advanced enough to let us peer back in time and space so far is astounding! hopefully with the new lunar exploration missions we can do even better
Absolutely! I can't wait to see where we go and what we discover next!
I find it truly fascinating to ponder on the idea that - due to this redshift, there may very well potentially be millions or perhaps even billions of galaxies out there that we'll never be able to see anymore because they're just out of range of the spectrum :3
I love the idea of not knowing if there is life out there bc makes us curious to explore.
So true!
your work is amazing i was little confused with the red shift thing when i heard it from neill de grasse tyson's interview but now the after watching your video the concept is clear for me thank you for the satisfactory answer, now i can sleep peacfully!! 😀😀😍
Thank you so much! I'm so glad to hear that you understood and appreciated my explanation 😊
I mean, compared to the extense of the universe, I'd assume that there's life out there, or at least has been. But just so far away that we sadly won't contact each others.
the question of life in other galaxies remains an enigma that continues to inspire scientific investigation and philosophical contemplation. While our current understanding is limited, the exploration of exoplanets, the search for habitable zones, and the advancements in technology provide hope that we may one day uncover evidence of extraterrestrial life.
I think there has to be life (comparable to our own) out there somewhere. The universe is way too vast for there not to be.
Love the video! Always great work.
Thinking about the possibility of life in other galaxies could be the craziest topic. Also thinking about if the other possible lifeforms would advance anything like ours.
We actually had about this subject in school this year, so I knew most of it, except the cosmological redshift. But it was cool to see this video now about it, a good refresher.
And yes, I believe there is life out there and it may be closer than we think. It must surely be life in another galaxy, and that they could be as advanced as us. Which would sugggesst that they also would have a hard time finding us. But it could also be as close as on the moon Europa, but they are likely more primitive
There is no other sentient life in solar system. Or else we would see their spacecrafts long time ago.
Given the sheer size of the universe it feels certain that there must be life out there somewhere even if it's something such as microscopic life on another planet
Finally, the term of “light-year” successfully been registered in my small brain. TYSM 👍
Haha happy to help!
good explanation of doppler vs cosmological redshift! i wasnt sure or the differences before
Thank you. So glad you enjoyed my explanation!
Excellent video describing how the universe is expanding. The cookie example is great!
Thank you so much! Really glad you enjoyed that explanation! 🍪
You guys are absolutely amazing. I've always loved astronomy, and I have learned so much thanks to you! This redshift effect is spectacular! Huge support from Serbia! 🇷🇸❤
As for life in space, I believe it could be found. Scientists have already detected frozen bacteria on one of Saturn's frozen moons, Europa if I'm not mistaken? I want to imagine our space is something like Star Wars, and that we as a human race won't dissapear. We'll be able to develop and peacefully interact with other species, once we discover them.
Everything is possible! I'm optimistic!
