#62I remember those waves on interstellar being a scarier adversary than Pennywise from IT. It must have been quite a sight. I wonder if any of the creatures from the event felt fear before the water washed over them.
I have long said that if I was given the chance to go back in time just once, and come back, I would return 66 million years ago to witness the meteor impact from the safety of a space shuttle. And now I have an idea for Elon Musk: interplanetary disaster tourism. Purposefully crash asteroids on remote areas of Mars and charge for front row seats. This would have the added benefit of bringing valuable metal ores to b…

Don't know how safe you would be. If I remember correctly, there's a theory saying that impact ejecta even shot out into space.
Crazy.

#63Can anyone explain how can it be 20 kilometers in depth and yet Mariana trench is the deepest place on earth 11km ?
The article says:
> The Chicxulub crater is an impact crater buried underneath the Yucatán Peninsula in Mexico.

It was an impact crater. Over millions of years it was filled with sediment, so it's not that deep anymore.

#65Just to put the numbers in slightly easier to imagine numbers: imagine ocean waves about 13000 feet or 4 kilometers high. No, I can't really imagine it either. In San Francisco, the tallest building is the Salesforce Tower at 1070ft. The biggest wave would be about 13 times taller than that. I totally have trouble visualizing it, other than just looking up and up and up.
Hm, I have much more difficulty imagining how far inside the shoreline that would go - so if I take a port city, is it wiped off completely? Does it matter if it goes uphill for 10km? 100km?

To terraform mars we'd need 3500 nukes per day for 7 weeks. That would be quite a show!
but... why..?!

I was wondering the same. the simulation doesn't appear to account for the landmasses, treating them as impenetrable barriers. where is the flooding simulation? are we to assume the shores were 5km high vertical rock?

It would save quite a few ocean going ships if this was more appreciated. Those once-in-a-thousand-year-rogue-waves are much more frequent than once in a thousand years. https://www.theguardian.com/science/2006/jul/26/uknews But we're still designing ships as though they only happen once every thousand years because the cargo and the ship are insured and the crews are considered expendable.
> Research at Imperial College, London, shows that far from being rare events, rogue waves can emerge frequently, and may be responsible for some of the 200 supertankers and container ships longer than 200m that have sunk in poor weather conditions in the past two decades. The loss of ten ships a year seems incredible to me. Surely "weather", if it were to blame, could be avoided. This amount of loss is steep. Is it…
https://www.statista.com/statistics/1326758/number-of-oil-ta...: There were 8,883 oil tankers worldwide in 2021.
If those are all ocean-going, ten a year is about 1.1%. Depending on how expensive it would be to prevent this, that may not be bad for ship owners, but it is very bad for those seeking a career in working on those ships.

When I went to the Grand Canyon I was surprised at how little my brain could comprehend the depth. There are so many false bottoms, when you're up on the rim, you look down and you see something you think is the bottom, but then you realize there's still a canyon below that, then you look down into that canyon and find the bottom, and then you realize there's still a canyon below that. It's like your brain absolutely cannot process being 2 kilometers above the bottom. That's what I thought of when I read your post.
(I had a similar feeling when I was in the High Atlas mountain range in Morocco and tried to look up to the top)

#70I struggle to imagine the impact of 2+ mile high waves. I’m imagining that much water would scour the land clear pretty severely.
It'd make everything wet, and do some other stuff.
