Thank you sincerely for sharing the article. It raises an important question — if such large impacts could cause transient subduction, wouldn’t they also disturb the early biosphere? As I understand, there was no stable biosphere yet in the Hadean, but even so, such events might have helped life...
I agree that there is no evidence for passes of moon- or planet-sized bodies within timescales relevant to Pangaea. Nevertheless, important questions remain. I would focus on processes related to the mantle and lithosphere. A significant step forward would be the ability to observe a planet...
Although I am not a physicist, I can logically conclude that the problem is not limited to the idea of an “expanding Earth.” The Pacific Ocean will continue to contract until this process becomes impossible. At that point, a “major change” could indeed follow, along with a renewed awakening of...
This article is exceptionally well written and full of valuable information. There is definitely much I can learn from it. Nature publishes only scientists who have truly proven themselves — a dream for anyone devoted to science. My sincere admiration goes to the author, Michael Marshall.
I am neither a physics student nor planning to apply. To my great regret, the profession I have chosen is very far from science. Writing on scientific topics is my hobby. I am not a famous writer, only an amateur, but I like, before I write something, to have researched and understood it (this...
I agree. I have realized that it is unlikely that a cosmic event could have caused the breakup of Pangaea. It certainly could not have been an asteroid impact, since the biosphere was flourishing at that time.
English (revised version):
I agree that the spreading of the ocean floor pushes the continental fragments, but before that the fragments had already separated from one another. For example, the current expansion of the Atlantic Ocean is exerting pressure on the Pacific Ocean, which is...
I don’t mean a direct impact of a cosmic object with Earth, but rather a sufficiently large body passing close by, exerting some kind of gravitational pressure. Otherwise, we are left with the theory that the continents simply ‘decided’ at some point to break apart and start rotating.
I’ve been told that these lines are cosmic artifacts captured by the telescope when a satellite or small piece of space debris passes through the field of view. They say they are not real lines, but…
Oh, yes, it definitely feels different here. It’s even cozy. On other platforms, if you don’t have at least a few thousand followers on social media or you weren’t invited by someone, you’re not considered “worthy” of being there.
No one replies to you. I don’t know what has happened to people...
This is true, but there are enough remaining traces for us to have an idea of what happened. For example, something disrupted the integrity of Pangaea, and after that began the 'great journey' and rotation of this landmass. If we look at this journey in terms of time, we can at least make...
Thank you so much!
I want to tell you that you are the very first person who has written anything to me.
On other platforms, people have disappeared as if by quantum magic since 2020. I have never felt this way before.
Thank you again for your kind greeting.
