Otherwise landed in 2004 with its twin - MER-A, better known as Spirit. These six-wheeled golf-cart-sized robots were Swiss army knives of geological lab instruments. Opportunities most spectacular discovery where these cute little so-called berries. They turned out to be concretions of hematite - which means they were grown in wet environments with dissolved iron. Wet means water FYI. Both rovers found a variety of other geological signs of past water activity, really solidifying the picture of Mars' much more liquid past. Both rovers were supposed to shut down after around 90 days as Martian dust accumulated on their solar panels, cutting of their power supply.

It occurs to me that they really reused that idea where humans were prohibited on the robot planet, in a later episode where humans were prohibited on the every-other-kind-of-ape planet. So they were running out of ideas. Still, it sucks how the good one had to go, between futurama and the simpsons, which one stuck around for hell's own time? The simpsons. Between Beavis and Butthead and King of the Hill, which one was around for so much longer? King of he hill. It's like the media organizations are run by idiots.

And he took the papers and analysis and he did multiply them a thousandfold, so that each had research to pursue. 4. And they said unto him 'Teacher, the results are ambiguous and contradictory and we can reach no firm conclusion.' 5. Yea, and he said to them 'So it is, for I come not to preach gospel truth, but to encourage thinking and exploration.' 6. And each of them went their own way, a little wiser.

Huygens: life can’t exist without water. Huygens probe: that’s what YOU think.

@frankschneider6156 5 лет назад

It's very likely that all naturally occurring life in the universe will be based upon water (primarily due to it's ubiquity, although some other properties also help), but that's a completely different statement than saying: Life can't exist without water. Assuming our knowledge about the minimal genome increases and we would be able to theoretically tailor proteins (which quantum computers should enable us to do), it should at least be theoretically possible to create a living, self-replicating cell based upon THF or DMSO instead of H20.

@ThePrimalEarth 5 лет назад

Frank Schneider I was makeong a joke about how Huygens said life can’t exist without water but the Huygens probe went to titan, a place were life might exist without water

@frankschneider6156 5 лет назад

Yes I understand that, although the likelihood of existence of extraterrestrial life within our solar system is extremely weak. But I was solely referring to the first part. It's imho important for people to understand that all extraterrestrial life we'll ever find (IF we ever manage to somehow find some) will be based upon water, but this doesn't mean that life necessarily has to be based upon water.

@ThePrimalEarth 5 лет назад

Europa Ganymede Callisto mars Enceladus Dione and titan, all have liquid subsurface oceans with more water than earth. If not one of those moons has life I will be EXTREMELY surprised. Now yes it will most likely be microbial life but still. Life’s life. Also do yourself a favor and google “Azotasome” it’s a hypothetical cell made out of organically based in liquid methane, not water.

@ThePrimalEarth 5 лет назад

Edit: mars has a subsurface lake. Not an ocean.

The scientists believe in truth and knowledge but they aren't the ones writing their paychecks....

@benjaminolsson2162 5 лет назад

@@user-pg3sw6kk7v If enough people has access to any information, we will know, due to leaks. Even if someone tried to cover it up. That is why all the conspiracy theorists are wrong by default. Take flat earthers for example. They think every scientist in the world is paid off to "trick" the population that the world is not flat. Every single observation ever made points to it being a sphere, including photos from space. But they just call it a hoax or CGI since that proof is irrefutable, and debunks their entire world view. My point is that it would be impossible to keep any significant discovery from the public. If life is discovered, they would probably announce it in papers around the world. The same goes for anything that points to anything intelligent ever living there. And such a discovery would increase their funding as well, so them having paychecks at all is just another motivation to get the word out to the public. And getting mentioned in the history books is something I bet many scientists dream of when reporting any findings. TL,DR: If they find something. We would know. There is just no way to keep something that big a secret.

@tuseroni6085 5 лет назад

weirder still would be finding that life on earth originated on mars. remember that meteor from mars showing up on earth at around the time life show up here...doubt it would be the only one...could be a bunch of such meteors all over the solar system, coulda been a good number hit earth, could even be some on their way to another solar system...the idea of "panspermia" life can originate on one planet and through cataclysmic actions end up being ejected all over the galaxy... could end up finding that life started elsewhere, maybe on mars, and then evolved here.

Please never stop hosting PBS Spacetime! You're by far the best fit for this show that it's ever had. My guess is that mankind may have started on Mars and had to escape the dying planet. We are a species with amnesia after all. I've dreamed of future Mars colonists on an archaeological dig unearthing (unmarsing?) relics from an ancient civilization that is recognizably human. That would totally wreck our current understanding of history.

@Tomyb15 5 лет назад

I have a question with past episodes regarding entropy and qed. In the episode on quantum electro dynamics, you explained that positrons are electrons going backwards in time. In the episodes about entropy, you explained that the second law of thermodynamics is the only law in physics that makes a difference between teh past and the future and could be the 'source' for the arrow of time. My question is whether the observed asymmetry between the relative abundances of antimatter and regular matter in the universe could be explained as some form of consequence of the inevitable increase in entropy of the universe that sort of creates the flow of time and applying that to the framework of qed. This is probably a dumb question but it seemed intriguing to me. I don't see how the emergent property of entropy (as purely a statistical consequence of the many microstates of a system, each consisting of regular particles described by the rest of the laws of physics) could have any bearing on the flow of time of a single positron. What I mean is that, from just watching the episodes on the subject, I got the impression that the flow of time would be a sort of emergent property that doesn't really exist on the micro level, but that doesn't sound quite right.

@BanterlordHades 5 лет назад

Ciroluiro the positrons are not ACTUAL electrons going backwards in time, however mathematically they are the same thing, as postulated by the Dirac Equation. Nothing actually travels back in time here. Hope that helps

@sebastianjovancic9814 5 лет назад

@@BanterlordHades How are we empirically certain of this difference though?

@BanterlordHades 5 лет назад

Sebastian Jovancic well if you look at this in the sense of a QFT, all electrons and positrons are, are fluctuations in a field (an electron field? I guess) and so in that sense, it doesn’t make sense to describe a fluctuation to be occurring backwards in time.. although mathematically it does

@frankschneider6156 5 лет назад

Ciroluiro The interpretation of a positron being an electron traveling backwards in time results from feynman's sum over histories / path integral and shouldn't be taken seriously. Yes the arrow of time is defined by increasing entropy and our relative timely closeness to the big bang (so an overall low entropy state) Finally: at this moment nobody knows, what the exact reason for the asymmetry between antimatter an matter is, so neither I (nor Matt) can tell you. But what is very interesting and most people seem to ignore is, that only 3 forces (strong, electro-magnetic and gravity) are perfectly symmetric. In contrast the weak force doesn''t give a damn about symmetry and violates all kinds of symmetries regularly (e.g. sends out electrons more to the left than to the right etc). The most likely explanation for the asymmetry between matter and antimatter is therefore, that a process of the weak force was somehow involved that created a little bit more matter than antimatter in the universe, so that after annihilation only matter remained. Thus what we have and therefore our existence is very likely just the fact, that the weak force is not a strictly symmetric force. Of course that's just a speculative hypothesis. A reasonable one, but still highly speculative. But as nobody really knows, that's probably the best answer you can currently get.

If we ever find evidence of past life on Mars or actual current life, and that it turns out that that life is related to that found on earth and we could rule out that one planet has received a transplant from the other following some catastrophic collision billions of years ago, then that would mean that life came from somewhere else in the solar system or possibly beyond instead of spontaneously appearing in both places. I would find that just as much, if not more fascinating. Some random or intentional colonization of primitive life forms from outer space. We could have a whole region of the galaxy with the same building blocks of life, perhaps even compatible DNA. Better watch out for those super smart alien hybrid babies.

DRILLING. Someone from a drilling background please calculate the weight (please use metric measures) of drilling pipe per meter. At 1.5 or 2 km (that would be 1500 to 2000 meters of pipe), how much would that alone weigh? It is presumed that this would have to withstand high torque, deep cold, perchlorates, bending and abrasion, and so let's not go the route of 3D printing of drilling pipe, please??? Also, determine the number of premanufactured drilling heads and how much each would weigh. Then consider the typical drilling derrick, even specialized for Martian conditions. Maybe some components could be fabricated using 3D printers on the surface, but consider the scale and the refining of each part for assembly, and the time to complete assembly. Further, what about false starts? You know, wells that don't quite hit the black gold, texas tea, ah, err, no we are drilling for water. Would the drilling rig have to be moved or relocated due to some kind of strata that gets in the way? Also, where is this drilling project going to take place? Will it be at the Pole? Although I read that the lake was not detected below the icecap, but several Kms away from there. But what of the climate, the supply chain from any decent landing places? Did the drilling team bring trucks? And are those Tesla trucks with really good batteries and chargers? And what about charging units? And drilling crew habitats? And food production, sanitation, storage tanks, pressure systems to prevent the lake exuding onto the Martian surface and collapsing the land (because of our scientific fracking???). And roads. And cinemas. And work out rooms. And repair shops. And garages for vehicles and tools. Geez, the list goes on.... All because of "drilling". Ergo: "WE COULD DRILL" just opens a can of worms of the infrastructure and supply chain that is necessary to drill down even 100 meters. Come on, boys and girls. We have to get serious with these simple proposals.

BFDT Don't try to see or create problems, where there are none. That's water ice. This means you just need a probe that's heating itself sufficiently up (e.g. via a Pu battery). That way it will melt the ice around it and sink automatically to the bottom. This works because the density of ice is less than that of water, meaning that the the same amount of ice occupies a larger volume than water. Otherwise the probe would just sit on a water cushion as water is in first approximation in compressible. The only thing required is a strong enough sender and a sensitive enough receiver on the surface or in orbit to transmit the results back through the ice, once the probe melted itself through the ice layer.

There is also the possibility that the lake is less cold that we think (and therefore contains less perchlorates) if is heated by geothermal sources (or areothermal if you want me to be precise). Even if Mars core is "cold" as we think, it should have lots of residual heat. We have to wait for InSight to measure temperatures below the surface of Mars and the resonance between the different layers, so we can have a much better estimate of the temperature of Mars' inside, and not just predictions based on different models. In that case, the possibility of life on those lake would be much higher (considering subsurface lakes on Antartica have lots of life). Even if the life started on the surface during the "hot and wet" period of early Mars, it could'vemigrated and survived in thousand of underground lakes and caves (we also more modern and better equiped satellites to find them).

1. The changes in volume were absolutely torturous... 2. "Wet means water" isn't always true. Wet generally implies water, but wet just means liquid is (or was, in this case) present.
