In the commentary of the book, written years later, he apologized because "at the time we didn't know mercury was tidal lockedto the sun" ... Almost 30 years later his original story was vindicated!

Jupiter captivates with its size and unceasing red storm larger than Earth, itself. Saturn surrounded by breathtaking rings. Uranus and it’s axis so incredibly askew.

But all in all, Mercury is thought of very little and i'm thankful that NASA is taking the effort to research it as they would any other planet, especially given the unique challenge of getting a probe to orbit such a small planet, so close to the sun. I don't know what all the practical uses for this research could be, besides a possible base of operations for any future dyson swarm project, but the data coming out of these missions has been fascinating.

@@alphagt62 There is one form of science which IS settled, of course, and that's climate science. It's a new form of science in which pressure from the media, pressure from one's employer, and computer models based on incomplete data and vast, poorly understood systems are combined to give predictions which are agreed upon by all scientists. Reputable media sources all say this. A few denier scientists keep citing OLD climate predictions and saying they didn't come true. Well, duh, that's because those are OLD predictions, and science has moved on since then. Our new predictions agree with theory better than before. As an example of how science is always getting closer to the truth, we now know that "carbon" is slowly killing life on earth. Plants may use "carbon" to photosynthesise, but humans and animals aren't plants and we would be better off without carbon (or is it carbon dioxide? I'm a bit hazy about that now). If necessary we could probably get the scientists to design a new gas that wouldn't be as harmful as CO2. Photosynthesis pales in comparison with the importance of our climate. If the temperature rose just 2 degrees, which is often less than the difference between one summer's day and the next, entire ecosystems would collapse.

@@AnalyticalReckoner bro, who said anything about altering lunar orbit? We don't have the capability to do that, and likely won't gain that capability before we most likely all kill each other off. By "gateway to the solar system", Corto means that because of a few key factors -- lunar gravity is ~1/6 that of Earth's, the moon sits significantly higher in Earth's gravity well than the surface of Earth does, and the moon has surface deposits that could be useful for powering spaceflight, e.g. water ice -- if we ever intend to send more than small, individual, unmanned missions beyond Earth's gravity well to places like Mars or further afield, we need to establish infrastructure on the moon to use it as a waypoint in those journeys. A direct trip from the surface of Earth isn't practical because of the enormous fuel requirements. An eventual manned trip to Mars, for example, might look something like: ride launch vehicle to infrastructure in Earth orbit; in Earth orbit, refuel launch vehicle or transfer to Earth-Luna transporter vehicle for trip to Luna; rendezvous with lunar orbital station or land at surface facilities; refuel or transfer vehicles again in preparation for interplanetary cruise phase of mission; launch interplanetary cruise from lunar surface or orbit; arrive in orbit above target body, e.g. Mars. Personally, I think we're jumping the gun with talk of manned missions to Luna and Mars at this point. We need to leverage artificial intelligence to build the required off-world infrastructure with semi-autonomous unmanned trailblazer missions. That's how we bootstrap our way into the solar system. Sending humans beyond low Earth orbit right now is just a hubristic boondoggle, much as maned moon missions of the 20th century were, now even moreso given our greatly improved ability to perform scientific study remotely.

I think the view I would most like to see is on the surface of Saturn's moon Titan. It's the only other body we know of (other than Earth) that has an atmosphere that can maintain a system whereby a chemical compound can exist in the three basic states - solid, liquid and gas. On Titan that's not water, but ethane/methane. So that means it rains on Titan, but because the surface gravity is much lower than on Earth, the 'rain drops' (it's been estimated) would be the size of golf balls but would float down like we observe snowflakes. That would be so beautiful to see, imo.

In my graduate courses, I learnt that Curie law of magnetism predicts that as temperature increases, its magnetic properties fade away. How can a metalic molten core still sustain a magnetic field? Would the magnetism of a hot metal depends on the chemical composition of the core??
@cobruh8363 жыл бұрын
maybe its just much more magnetic than hot? idk, what youre even talking about tho, so you know my level of physics education :D maybe theres a difference for permanent and electro magnets, i mean a cold electro magnet wouldnt even be magnetic right? because the energy that makes it magnetic produces heat.

Non-standard pressures probably violate the supposed "law" you were taught about with no regard for intense pressures forcing molecules into aberrant and magnetic arrangements. The Sony minidisc records using a focused laser to heat it's material during the flux change varying as the music does. This is a substance that violates Curie's test bench in the opposite flip. It remembers the flux when heated and is unaffected by anything happening at colder temps. So you were not taught the entire truth of a "law" that has these loopholes large enough to drive a truck through. The folly of man is believing things that just aren't so, welcome to the club of hooman.

Yes, Mercury's coincidental double rotation to one revolution is kind of like the coincidental moon to sun ratio, which is the sun being 400 times the distance of the moon to Earth, and 400 times the diameter, making a perfect lock and key eclipse. Of course, it seems more plausible to me that these "coincidences" are intentional design.

6:30 - 7:00 So, taking all this into account, and that Mercury has quite a bit higher density than the other Solar system's other 'terrestrial planets' (indeed, it's thought that it might once have had an outer rocky layer than has been smashed off - perhaps accounting for it's more elliptical orbit?). Well, how about this as a hypothesis...? It has been noted that 'super Earths' are quite common in other star systems, yet ours has none. What if Mercury is the core of such a super-earth that once orbited where the asteroid belt now resides, and which is itself the smashed off layer of Mercury's previous form? Maybe Mars was initially a moon of this super-Earth? Or instead maybe two Earth sized planets collided in that orbital space? Just thoughts.... although I'm sure such scenarios have already been considered already, right?

@Dragrath13 жыл бұрын
To be fair it wasn't a coincidence that was the only time we looked since there is a limited window in our orbit around the Sun you could observe the planet with a telescope without looking directly at the Sun. Telescopes and sunlight don't generally mix very well at least not without special solar filters and even then dim Mercury would be virtually invisible compared to the blindingly bright Sun. You need a Coronagraph to be able to really get a good look Mercury at any other time. Now why the period of mercury's day and our observation window happen to be an exact integer ratio is more difficult to answer for sure, but given that the tidal effects of Venus Earth and Jupiter on Mercury are not negligible tidal effects may have played a critical role in this. Recent work suggests that an 11 year alignment between Venus Earth and Jupiter inducing tidal effects on the Sun appears to be a promising candidate for driving the abnormally regular magnetic reversals of the Sun. If such tides are significant enough to effect the sun what effect might happen if Earth wasn't at some integer multiple alignment towards the length of a day on Mercury since remember Mercury is in a spin orbit resonance which is controlled by tides. In fact thinking about it if Mercury wasn't aligned at an integer ratio it would be possible for Mercury to align at aphelion with respect to this 11 year resonance. This would raises the real possibility that should Mercury's orbital eccentricity would be increased. Over multiple such encounters Mercury could continue having eccentricity boosting tidal interactions as its orbit lined up with these 3 planets which would then incrementally increase the planets eccentricity even more as the planet would be further from the Sun at aphelion. This could set off a positive feedback loop further boosting eccentricity every time the planets aligned to boost Mercury tidally which would end in 1 of 3 outcomes if the feedback loop wasn't broken through a destructive resonance.The first possibility would be that Mercury's perihelion would drag the planet's closest approach into the atmosphere of the Sun where further heat and dynamical friction would take over to drag the planet into the Sum. The second and third possibilities are that Mercury's aphelion may increase untill the planet's orbit begins o intersect with the orbit of Venus either resulting in the ejection of Mercury from its orbit and ensuing chaos or worse lead to a collision between Mercury and Venus destroying both planets and creating an enormous collisional cascade that would invariably have the potential to destroy the Earth as they formed a new inner asteroid belt. Thus far this doomsday alignment has not occurred yet which may in some way be linked to this seeming coincidence. If it isn't directly related then that would be a bit scary as research indicated that barring some preventive resonance there is otherwise a 1% chance per billion years for Mercury to end up in this alignment either resulting in the destruction and or ejection of one or more of the inner planets in a myriad of chaotic scenarios which all ultimately would doom life on Earth. Basically it may be down to luck but also potentially the anthropic principal in the case there is a tidal link since naturally if we weren't oriented such that we couldn't align with Mercury in a way that would destabilize its orbit there would be no Earth our planet having been reduced to rubble billions of years ago thus naturally there being no one to observe Mercury. One of the alarming discoveries is that the solar system is chaotic and precariously balanced primarily because of Mercury's eccentric orbit.

Tidal forces etc aren't nearly enough to account for phenomena like Enceladus' geysers for example. Or the strength of some of the magnetic fields.

@@jeannetteparry5587 Do you know what solar wind is? Hydrogen and helium ions, and to a much lesser extent, other lightweight ions ("light" meaning sub-iron, much of which might be called "volatiles"). By the inverse square law, the density of solar wind at Mercurian orbit is about 7 times that at Earth orbit. That's still very thin, but it does allow for Mercury, with gravity approximately equal to Mars and the strongest non-solar magnetic field inside Earth's orbit, to pick up a significant amount of Hydrogen and Helium in a dynamic balance of gain and loss. As for the rest of your comment, you can't simply state falsehoods as fact. (Well, you can, as your doing so proved, but it's not a compelling argument for anyone who isn't either already in agreement with you or a fool.)
