James Webb's 13 Billion Year Old Picture

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.

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

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.”

[centryll]

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

[hammyjammy]

This is easily the best deep space video I’ve seen where I’ve actually learnt something completely new.

[stelabouras]

That was an amazing and really easy to understand explanation of Redshift. Keep up the great work!👍

[clarkgourguejr]

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!

[silly_gooses]

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

[saahas]

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. 😃👏

[coolguy-bskr]

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.

[jack]

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.

[CosmicExplorerX]

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.

[sandeepvengsarkar]

Truly humbling to know our place in this universe.
How little we know of dark matter, dark energy - the relationship between time and space.
The tools at our disposable today might seem cutting edge and perhaps even give us a tiny glimpse into our past but just as the light from the past seems to catch up our present has moved away.

[lukeblignaut]

Can't wait for the James Web telescope to capture a million year old image of an alien flying by. That would be amazing.

[THE_HALALBOI_yt]

I have never understand something explained in a nutshell as much as the example used in this video 😂

[pmrego]

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 🙃

[RaptorBoy]

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.

[bfb]

Strangely terrifying. But if you think about it, it's better to have a universe expanding outward than collapsing inward.

[EdwinRussell]

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?

[IIISentorIII]

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.

[Yoshivettel]

I love the idea of not knowing if there is life out there bc makes us curious to explore.
