I wish you had mentioned US Naval Captain Harry Hess, a geologist in civilian life, who sailed many missions back and forth across the Atlantic during WWII. He had the brilliant idea of towing a magnetometer behind his ship and recording the data. This was the discovery of the strips of basalt with alternating magnetivity along the mid-Atlantic Ridge. This discovery, along with other significant ones, led to the formulation of plate tectonic theory at the famous Asilomar conference in 1970. There has been an accumulation of evidence to support this theory, one of the most important of all science, in the 50+ years since.

Absolutely awesome series that unlike higher budget mainstream productions respects the intelligence of its audience.

These videos are aesthetically pleasing in every way - the information is perfectly arranged by explaining the question so that you understand what's being asked, the answers contain easily comprehensible science, the narration is expressively soothing to hold your attention, the video and graphics are beautiful and explanatory, and the editing is seamless. Wow! This was a delight, and as close to perfect as you can get.

Such a humbling experience, being reminded of how fragile our existence and way of life are. Thank you for your fabulous work. In all your channels. You put most "professionally produced" documentaries to shame.

Thus far my favourite episode.
When I was into amateur radio back in "boom days" of sky wave we'd speak of these phenomena for hours. But, then came the flares! COMPLETELY shutting down the radio spectrum from 0 to 30, 000 khz. And beyond, sometimes for days.
STILL fascinates me.
Great video 👌

I love how hauntingly beautiful the intro music is for this series.

Let me tell you something, generally these types of videos aren't my cup of tea. This however is so different, not monotone, beautiful transitions, calming music, clear concise narration. 10/10!

[MatthewLong]

Love the long format. I kept thinking it was over and it wasn't. I'm very familiar with the subject but I learned quite a bit from this. Nice job!

[twheys]

I love the subtlety of this statement: "Our continued existence on this planet suggests that it wasn't in fact the end of days"

Finally, a presentation on this subject from people that know what the heck they are talking about and know enough to explain it while presenting ways for us to understand as we watch it!! THANK U SO MUCH!!

[VeronicaCawelti]

You have a real talent for turning dull science and history into pure poetry. I follow all of your channels and share them too. I just wanted to say Bravo! I look forward to the next one!

[tpxchallenger]

The scripts and narration in this series are absolutely first rate. Among the best of any documentaries I've seen, and I've seen plenty. Looking forward to more!

[brittneystreeter]

I don’t know how I found this channel but I’m glad I did! Truly amazing!

[nealthomas]

I find these videos utterly engrossing, they are at the same time fascinating in their content as well as captivating in terms of one's imagination. I cannot recommend this series highly enough...

[MarcusAgrippa]

Must say you have an excellent voice for this type of video, it's calm and not all over the place with volume and such.

[YogiMcCaw]

Another great recap of an important scientific phenomenon. You guys are keeping the tradition of great science documentaries alive!

[JungSooLeee]

Huge respect to the cameraman that went back in time to capture the footage for the prologue.

[Abalone.Baloney]

Dude this series is so underrated, your doing an amazing job and please keep up with the amazing videos! :)

[iLLeage]

Im just saying Carrington was a true scientist. He recorded the sun's spots everyday and took notice of something that literally none else saw
