@Viktor Birkeland @Viktor Birkeland @Viktor Birkeland @Viktor Birkeland Yes, opinion. It's okay to have one. But I don't think it's as broad as you seem to think. I don't think everything you say is your opinion. If you leapt to your feet, mid meal and cried, "help me I'm choking!" I doubt you'd find any comfort, if I were to reply; "well, don't worry that's just your opinion.!" Also, I was puzzled by your ironic wobbliness around absolutes. - "I don't speak the truth, in no way." - Is that statement then untrue? Or if it is true, that you do not speak any truths, is that itself then not a truth? You see the bind! What tickles you one day, may not another. But to say that Rich Hall is not funny to you, because he's not funny at all is just nonsense. And evidenced to by all the laughter surrounding his humor on the show. He is particularly funny on QI, though I wouldn't be drawn to his stand-up... as a whole! Someone is not funny because you laugh at them. You laugh at them because you think they're funny. It's all transactional. - And I've seen the interview from which you quote, and it is a good observation of cultural differences. But that's more an overarching trend, and less the individual. There is no doubt that things are humoress. But of course, you may wrestle with personal doubts, as to where you find that humor. Try not to kill things off with absolutes. Let them off! At least then, there's a change they may come back and surprise you. -- Anyway, forgive the wordy response.

@@simonextra9689 While I believe that it may be possible one very distant day, I do not believe that it is something we will see in our lifetime. I would like to be wrong on this.

I feel that they weren't laughing so much at the idea of colonising Mars, and more at the way Alan worded it, to sound as though everyone present in that room would be living on Mars.

Alan expressed it poorly. What Channel 5 was attempting to get through to him was that when the Sun finally runs out of fuel for nuclear fusion (estimated time of arrival: 5 billion years from now), then it'll expand, as it becomes a Red Giant. It's not quite known how far the Sun will expand into the Solar System exactly - too many variables involved to be that precise - but Mercury will definitely be consumed by the expanding Sun, and Venus almost certainly. It might make it out as far as the Earth and eat our planet too. But, you know, even if the expansion doesn't quite reach out to Earth's orbit, then the planet will be right next to a newly-expanded Red Giant and will be absolutely inhospitable to life. The seas and the atmosphere would boil off, leaving Earth somewhat like Mercury is - a barren rock that's some 400C in the day and approaching Absolute Zero by night. Indeed, the only thing that could handle such a wide range of temperatures is a barren rock. So the notion is that if humans haven't left this planet in 5 billion years' time, then we'll be forced to leave by the expanding Sun. To be honest, Mars is probably still too close to this larger Sun as well, but at least you're moving outwards to a safe distance. And beyond that is the asteroid belt and then Jupiter and then Saturn - gas giants that the video covers as being impossible to live upon - so places to live quickly run out after Mars. Though, this "thought experiment" is a bit moot, upon closer inspection. I mean, we're talking about 5 billion years from now. And it's been 5 billion years-ish from the beginnings of the Solar System to today. About as much time left, as has already passed. This is a ridiculously long time and the idea that humanity would still be humanity in 5 billion years' time is frankly impossible. If we haven't long since gone "trans-human" with advanced technologies by our own steam, then evolution by natural selection will have warped what used to be us into something completely unrecognisable by then, anyway. Again, we're talking about a stretch of time - "deep future" - that's as deep as the "deep history" that got the Solar System to this point in the first place. The whole story of evolution up this point repeated again, but starting at this point in the vast journey, not at the very beginnings of life itself. And if you consider technological advance over the last century - and the fact that it naturally picks up pace over time too - then it's already completely unimaginable to contemplate what advanced technologies humanity would have a 100 years from now. So imagine technology 5 billion years into the future? Probably not just "indistinguishable from magic" but likely closer to "indistinguishable from omnipotence". So "stellar engineers" could, by that point, probably just pop over to the Sun and "fix" it, so that it doesn't expand in the first place. Or, you know, everyone (who aren't "humanity" anymore) lives on the inside of a Dyson Sphere that's been placed at exactly the right distance from the expanded Red Giant (and the stellar engineers just keep it like that forever more). If you don't know what a Dyson Sphere is, then look it up to realise how ridiculous a "tall order" that is - but, hey, 5 billion years' worth of technological progress? Child's play to the trans-human race. Or, you know, we possibly vote for an Orange Man who launches a nuclear war, just because he's exactly that stupid, that wipes out all life on the planet next week, because folks still believe in religious fairy tales and can't get over the fact that some human beings look a bit different to them, and they want a tax cut to be able to afford the extortionate healthcare that wouldn't be so extortionate, if they weren't so obsessed with tax cuts in the first place. One or the other. Chaos is, unfortunately, intrinsically unpredictable. So you never can tell.

Actually, two of the three criteria that the IAU came up with are crap. One says that a planet has to orbit the Sun. Not just a star, but our star. That means that by definition, none of the exoplanets is a planet. The other is the "cleared its neighborhood". How cleared is "cleared"? The IAU doesn't say. How big is a planet's "neighborhood"? Again, the IAU doesn't say.

Doesn’t that disqualify every planet with moon(s) as a planet then

@@almostfm The IAU refers specifically to the sun, because the criteria you're referring to are specifically for what qualifies a celestial body as a planet *of the solar system*. Exoplanets, by definition, are not planets of the solar system. Now, how big is a planet's neighbourhood? Their neighbourhood is their orbital path. More accurately, an area around their orbital path which, if anything else was within that area, it would succumb quite heavily to gravitational forces from the celestial body in question, or vise versa. "Cleared its neighbourhood" is not hard to understand. It's simple. "Is the celestial body the dominant gravitational influence within its orbital path?" It not only asks if its the most massive object within its neighbourhood, but also if the combined mass of everything in its neighbourhood doesn't outweigh it. This doesn't take natural satellites into account, so Charon being quite large isn't the reason Pluto is a dwarf planet. A significant portion of Pluto's orbital path, however, is within the Kuiper belt. Its neighbourhood is shared by millions and millions of asteroids, as well as other dwarf planets of similar size and mass. If a planet of comparable mass to Earth were to replace Pluto, the Kuiper belt would eventually disappear, or at least the inner edges of it would be cut back quite a ways. Much of it would be ejected. A ton of it would collide with the planet. Some of it might even become moons of the planet. It might take a few dozen orbits, which would take thousands of years, and it would still be classed a dwarf planet until its neighbourhood was clear, but the point is, it could clear its neighbourhood. Pluto is not massive enough to ever clear its neighbourhood. At least, not within any reasonable amount of time. It's been around for 4-ish billion years, and the Kuiper belt is not showing any sign of damage. Meanwhile, the 8 planets aren't being shrouded by the asteroid belt, because they had no trouble cutting it down to size.

@@PyroOfZen How many times, since the planets formed, has Pluto circled the sun? Earth has swept its orbit some 4.5 billion times compared to Pluto's 18 million or so, less than .5% the opportunity Earth has had to sweep its neighborhood, which is also a hell of a lot smaller than Pluto's. For a group of scientists, the IAU have allowed their criteria to be extremely biased against any smaller planet in a more distant orbit. Put a naval officer in charge of a dinghy and the boat will sail well. Put a toddler in charge of a battleship and it won't. Give the kid a chance to grow up and learn the ropes, and don't congratulate the inner planets whose orbits were mostly cleared by Jupiter.

Pluto hasn't cleared its neighborhood because there is nothing to clear. We should send a few asteroids Pluto's way so it will have a chance.

He’s probably right - over the next billion years, an increase in solar activity will make the surface of the earth uninhabitable, but Mars will warm up, giving it at least the potential for human habitation (if we can overcome issues like not having a Van Allen belt).

The Great Red Spot has been observed since 5 September 1831. By 1879 over 60 observations were recorded. After it came into prominence in 1879, it has been under continuous observation. The reason the storm has continued to exist for centuries is that there is no planetary surface (only a liquid core of hydrogen) to provide friction; circulating gas eddies persist for a very long time in the atmosphere because there is nothing to oppose their angular momentum. In the 21st century, the Great Red Spot was seen to be shrinking in size. At the start of 2004, it had approximately half the longitudinal extent it had had a century ago, when it reached a size of 40,000 km (25,000 mi), about three times the diameter of Earth. At the present rate of reduction, it would become circular by 2040. It is not known how long the spot will last, or whether the change is a result of normal fluctuations. In 2019, the Great Red Spot began "flaking" at its edge, with fragments of the storm breaking off and dissipating. The shrinking and "flaking" fueled concern from some astronomers that the Great Red Spot could dissipate within 20 years. However, other astronomers believe that the apparent size of the Great Red Spot reflects its cloud coverage and not the size of the actual, underlying vortex, and they also believe that the flaking events can be explained by interactions with other cyclones or anticyclones, including incomplete absorptions of smaller systems; if this is the case, this would mean that the Great Red Spot is not in danger of dissipating.

@@lanapowell - Wow! Thankyou for your reply. Its a breath of fresh air to get such an informed response from someone on KZfaq! 😂

According to the current writings from Nasa the ice giants are a form of gas giant. The report I read was dated Feb 2019, so I guess things may have changed, although the NASA website has them as Gas Giants but this is a much more simplistic (made for public consumption) source than the research paper I read.

Jonathan Thorpe Because they were classed as gas giants for a century, and the understanding that they are not is less than 20 years old, we are in a transition period. Also they do have thick enough atmosphere’s for some people to feel justified in continuing to use classifications that they learned as kids. However, it should be noted that their atmosphere’s do not extend more than 10 to 20 percent of their diameter. Like the Earth, and unlike Jupiter and Saturn, the largest part of the planet’s interior is an extensive mantle, although, unlike the Earth’s fluid rock, in the case of Neptune and Uranus, their mantle consists of fluid ices. Pluto’s demotion as a planet is similar in that while it is not classified as a planet, it is still easy to find references that still call it a planet. Likewise Ceres was reclassified as a dwarf planet, but people still refer to it as an asteroid, and because it resides within the asteroid belt, there is some justification in that. In the case of Uranus and Neptune, there is less reason to cling to tradition, as the study of exoplanets has revealed that these mid-sized planets are possibly the most common class of planet and exist within a certain restricted size range that suggests their origin and growth during the formative stages of a solar system is quite different to that experienced by gas giants. If so, then a classification system that clearly isolates them from gas giants like Saturn and Jupiter is more than just a simple matter of their interior composition. It seems that there are 5 distinct classes of planets - rocky terrestrials, super-Earths (of which there are zero known in our solar system), gas giants, Neptunes (which we have 2 of in our solar system both of which are largely slushy ices with ice/rock cores. Unfortunately we do not know the composition of exoplanet Neptune sized objects so we don’t know if the ice giant model is typical). The fifth class is dwarf planets which our solar system seems to have large numbers, but none have been discovered yet around other stars. As we cannot resolve objects that small yet, the absence of discovery is presumed to say nothing about their abundance (or possible lack of it) elsewhere.

@@artistjoh I'm not reading that. I'll stick to getting my info from NASA as opposed to 'Person on internet'.

Jonathan Thorpe I get my information from the same sources as NASA does, research papers. My main sources of information are reported in journals such as Nature, and science news such as Phys.Org and in current encyclopedias. As Wikipedia states, “Neptune, like Uranus, is an ice giant, a subclass of giant planet, because they are smaller and have higher concentrations of volatiles than Jupiter and Saturn.” Don’t be such a smart a**. Note that is says “subset of giant planet” not “subset of gas giant.” Perhaps you should do more research rather than being a smart a**.
