This week marks 113 years since the sinking of the Titanic, a tragedy that's captivated generations.

It's been the inspiration for three big movies.

Now, there's a new tool for exploring it.

A full-scale digital twin of the wreckage created with cutting-edge 3D scanning technology. That's the subject of a new National Geographic documentary,

Titanic, the Digital Resurrection, which is streaming on Hulu and Disney Plus.

Earlier I spoke with Titanic analyst Parks Stevenson.

I asked him to compare the virtual experience with the real-life visits to the wreckage in a submersible.

only carries less than 100 meters in front of you. So you only see the wreck a little bit at a time.

To see it all like this well lit up in context you can see off into the

distance that's a view that you never have at the wreck site did anything surprise you about what you

saw on the digital twin everything i saw surprised me my experience has been through dives through

studying digital imagery captured by cameras.

I've seen the wreck in context put together in the early days by artists who painted the wreck after they studied all of the imagery.

But that's all involving human intervention. This, however, is completely data-driven. And so now I'm seeing the

wreck in its context for the first time. What were some of the biggest questions that got

answered with this new way of looking at it? On the first render that was sent to me was of the

stern. I've always tried to

explain why the stern section is in such worse condition than the bowel section. And in this

first render, it was depicted so accurately that I could tell part of what we've learned that

the stern spiraled down, the rudder dug in, and the whole stern section

tweaked. When it tweaked, all those connections, the decks and the frames and the shell
