birds are dinosaurs. I’m not sure how much they evolved from their ancestors but I don’t think it’s much. If I were to guess Dinosaurs will live fine on the current earth.
They had millions of years to evolve.

Nitrogen is inert. Combustion doesn't need nitrogen. It just basically fills space.
As far as wildfires go, so is carbon dioxide. CO2 is not a typical reactant of combustion.
The earliest dinosaurs experienced 22-hour days.

As far as I understand, keeping such creatures alive would require facilities with enriched oxygen. If the large ones escaped, they would suffocate. "...large dinosaurs really required to be living in an oxygen tent. An atmosphere in the neighborhood of 35 percent oxygen would be considerably more compatible with large dinosaurs than one in the neighborhood of 28." Volcanic activity in the Cretaceous enabled these hi…
Hmm… I have a question inspired by your choice of phrases: Is there a graph somewhere of Earth's mean sea level atmospheric pressure over time? Was it significantly different e.g. a billion years ago?
The mass has reduced over time, due to solar wind blowing away our atmosphere. But compared with the mass of the friggin' earth, my intuition says atmos pressure has reduced only slightly
I love thought experiments like these, One would have to think where could ancient dinosaur DNA survive? Antarctica has been covered by ice for 5 million years, that is still 60 million years too young. Maybe there are a few bugs that have dino dna that is better preserved than the stuff that has been exposed to sunlight and elements the past 5 million years. And even if there is viable dna you would have to drill do…
My interest was piqued when you mentioned cuts would heal faster. Is there a video that explains what life would be like if the earth had higher concentrations of oxygen? (30,50,70)?
Unfortunately, I haven't heard ANYTHING about this. Did they bury this or something or has anything been released about this since then?
The dinosaurs lived in an incomprehensibly different world. From the food and nutrition to the very air they were breathing which we only have vague ideas about. That means the first several generations at the very least would suffer and die from various nutrition, toxicity and environment issues. Even after all that got figured out the dinosaurs would likely have be confined to some small controlled environment righ…
"Basically if we bring back dinosaurs it will be to torture them for our amusement and curiosity". Just a thought experiment, I hope I won't be downvoted to hell. Isn't this the predicament of all beings? You might say, that some people enjoy life, but at that point you should 1) Confirm that all beings are not answering with a Stockholm Syndrome 2) Confirm what is the subjective experience of the dinosaur
I meant that dinosaur are not biologically capable of living in this time period or this environment of earth. They would have to be on life support from birth. Even than it would take many years of trying before we figured out how to keep them alive. Which means they would start dying a slow agonizing death from the moment we create them.
It would be like dropping people off on Venus and saying make the best of the sulfuric acid atmosphere.
Have you ever seen a killer whale in captivity with its top fin floppy/not standing up straight. They have no idea why that happens in captivity they cannot figure out even after many decades of them being captive. Now imagine that with millions of years of difference.

Why would 30% oxygen be hard to deal for humans? I didn't think a greater oxygen concentration really mattered to us.

On mobile so I'll let other ppl sezrch. My $0.02: atmos pressure is a resultant of gravity, which is a result of mass. The mass has reduced over time, due to solar wind blowing away our atmosphere. But compared with the mass of the friggin' earth, my intuition says atmos pressure has reduced only slightly
First part is also why Venus, with a lower mass, is able to have about x89 Earth's atmospheric pressure.

Oxygen only one part and for all we know there were other trace gasses in the air they required that we don't even know about. There are all kinds of animals today we cannot keep alive in captivity because they require some sort of unknown sequence of environmental triggers to activate or deactivate various processes in their body. For instance cheetahs are nearly impossible to breed in captivity because their mating…
