These doom and gloom people say global warming will kill everything forget how life flourished back on Earth when CO2 levels were above 400ppm. But things will get nastier with more disease, more storms and higher mortality rate all around.

      That would be most of people's dreams, including me. yet you need to travel faster than light do to it. but it doesn't means that is impossible. they have proved time travel is "mathematically possible", not because we don't create time machines means that is impossible. but really hard.

    • @asdf30111
      @asdf30111 7 лет назад +15

      Faster then light travel making you go back in time is a fictional idea. From the observer's point of view if an object traveled faster then light towards them it would seem like the object is going back in time. They will see the object arrive 1st and then "travel" backwards as earlier and earlier light hits the viewer. These is disregarding all the weird things that will happen with ftl travel but going back in time is not one of the things even though to an observer it looks like the object split into two, one object that traveled towards them and one object that is traveling away from them and going "back" in time.
      However, if you could go faster then light, you can still travel away from Earth to see what it looked like in the past. So do not be too disappointed.

    Why did you skip the idea that the reason life on Earth survived the Oxygen Catastrophe is because aerobic bacteria evolved before the cyanobacteria could've gone extinct. Aerobic Bacteria are able to use oxygen + eating sugars from cyanobacteria for respiration, as opposed to making sugars with carbon dioxide + sunlight to then use. The existence of both in tandem is what causes our current atmosphere to balance somewhere other than completely CO2 or completely O2.

      The recovery part - sadly not. At least, not under any normal definition of lifetime.

The mass extinction is already very much underway though, and has been for a while. We will see that part ramp up noticeably within our lifetimes.

      I do think that complex life would probably require a similarly powerful energy source to O2, however. Aerobic respiration produces several times more energy than anaerobic processes, so without it, life would have to run on much thriftier energy strategies, possibly forbidding the development of multicellular life

    • @scaper8
      @scaper8 5 лет назад +32

      Remember that rust, typical red rust anyway, is iron _oxide._ There _was_ plenty of free oxygen on Mars. It has mostly escaped into space as Mars's atmosphere wasted away or was trapped in the rocks and dirt as iron oxide, i.e. rust. Thus a red, and now free oxygen deficient, Mars.

      M Mustafa one of the best ways to reduce CO2 is through carbon sequestration. Either through pumping it deep into the earth or through more natural methods. I like the idea of creating and restoring more wetlands. They do an incredible job of trapping CO2. Sadly we've converted a lot of them into crop land since that soil is also nutrient dense.

      SuperDipMonster I think I read that chopping them down and then treating them and using them in buildings might help, under the grounds that dead trees biodegrade in a fashion that release green house gasses. Of course you probably want to put more trees where you chopped down trees, and I'm not sure how much you can do this sort of thing before the soil nutrition becomes a concern.

    • @ProfessorEGadd
      @ProfessorEGadd 7 лет назад +21

      I didn't understand that either. The best I can find is that there is some debate amongst geologists about how and when the continents appeared. The Oxygen catastrophe occurred at the end of the Archean Eon, which was the first eon after the Earth's solid crust formed. Some geologists hold that the continental crust floated to the Earth's surface during the Hadean Eon, while the Earth was still entirely molten. However, other geologists maintain that the continents were nucleated over oceanic hotspots only after the end of the Hadean.
      Either way the continental crust, being denser than water, could only emerge above the surface of the sea once it was thick enough to float high out of the denser mantle. This process would have to take some time, so might have been still on-going throughout the Archean. Unfortunately (but perhaps not coincidentally) no known rocks are now to have survived from the Hadean to now, so a clearer answer is some way away.

    • @DracarmenWinterspring
      @DracarmenWinterspring 7 лет назад +4

      Hmm...I don't know any more about the planet's geology than what I've picked up from channels like this. The way I see it, if the amount of water on Earth only ever increased (from meteorite impacts?), and if as you say the crust was solid at this point, and if gravity pulls water towards the center of the planet everywhere so it mostly ends up in the "lowest" areas, then geometrically the planet would have to be smoother to have a larger % of the surface covered by water than now. Am I missing something in that regard?

    • @DracarmenWinterspring

    I get that the "goldilocks zone" is one of the easiest factors for us to look at in extrastellar planets, but clearly there are so many other factors at play that we can't see from here. Even in our case, our existence is surprising when you look at Earth's history, despite our planet's proximity to its sun. I think we grossly overestimate the likelihood of life on other planets.

    • @valen123456
      @valen123456 7 лет назад +2

      I suppose it depends on your definition of complex.
      One thing about the known universe however is just how absolutely huge it is. Our own galaxy is speculated to contain anywhere between 100-400 billion stars. Given that it is believed a similar if not even larger number of planets exist there, and that at least 200 billion galaxies are believed to exist, the shear number of places (planets, moons, asteroids) that might exist in many "goldilocks" sweet spots you mention could be much greater than you are giving credit.
      That is not to say they are actually close enough for us to find out about it or manages to survive for any length of time, but i believe its possibility is pretty high. If we manage to find life elsewhere in the solar system that gives it an even bigger push. If life can separately develop independently in at least two places in one star system then the odds go up even more.

      You're totally right.
      Even if life is extremely rare, there's still a good chance it can be found elsewhere, given enough planets. And this sort of numbers game is one where the universe certainly has a strong advantage.
      However, I'm mostly referring to how people make a big deal about the next "Earth-like" planet that's gotten the media's attention. Often times these planets aren't that Earth-like at all, given their size, or the type of host star they have. Even when we do look at all of the details we can observe from here, it's never nearly enough for us to flag it as "can support life". We can make a pretty good guess about whether a planet can host liquid water, but even that is not reliable, because even Earth has been totally encased in ice in the past. Our own Earth-like planet can be extremely inhospitable, depending on when you look at it.
      Of course, that's not to say that studying these distant planets and solar systems isn't valuable. I only mean to say that more of us should acknowledge how incredibly unlikely it is that any of the thousands of "Earth-like" planets we've already found actually support life; especially complex life like plants and animals.
      In any case, I appreciate your counter-point, because everything you said is correct, and helps put my own comment in perspective.

      I had considered that, but the problem with that idea is that we're just one example out of billions. Sure, we could look at our own example and conclude that life is persistent. However, the probability of us observing our own example as a failed attempt at intelligent life is 0. Obviously life survived in our example. If it hadn't then we wouldn't be around to observe it.
      Suppose the likelihood of life surviving is extremely small. Given the vastness of the universe, there's still a good chance it will happen at least once. My argument is that we are that one case out of billions where it actually works.
      I find it easier to believe that "Earth-like" planets are too inhospitable for life than to believe that life is so persistent that it can survive whatever nature throws at it.
      Nonetheless, you present an interesting counter-point, and I reserve the right to be wrong.

      We have the added complexity of having a sample size of 1. We have visited 1 planet and it has life. Any idiot who has ever added two numbers together can tell you that is not valid. I agree the numbers are so large that need to give any single factor a small significance. But still we have no way of determining the chance of a perfect duplicate of Earth developing life. That is why we need to go to Mars.

    was the sky really blue in the phase with nearly no oxygen in the atmosphere? also - why was this just 5 mins long :( i like your content, give me moar

      MasterAlke the atmosphere was mostly made up of nitrogen then as it is now. Both nitrogen and oxygen scatter blue light more than they do other colors in the visible spectrum. So that probably makes sense.
