Hot Jupiters May Indicate Hospitable Planets

eldavojohn writes "An interesting article from National Geographic points out that other solar systems which contain planets like a 'Hot Jupiter' have a higher chance of also containing Earth-like planets." From the article: "'We now think there is a new class of ocean-covered--and possibly habitable--planets in solar systems unlike our own,' Raymond said. The simulations also showed that rocky planets known as hot Earths may often form when hot Jupiters push material forward during their inward treks. But hot Earths, which can be up to five times bigger than our Earth, orbit closer to their stars and are not likely to support life. Even if water does contribute to their formation, most hot Earths probably end up dry, study co-author Raymond says. "

      I've been studying extrasolar planets for exactly 40 years. My findings don't agree at all with the hypotheses presented in the article. Here is what I've found out:

      • All extrasolar planets have a mass and density such that gravitational acceleration at the surface is 9.8 m/s^2.
      • All extrasolar planets have an atmosphere breathable by humans and a surface temperature of approximately 70 degrees F.
      • Imaging shows that from space, in the visual wavelengths different extrasolar planets reflect a wide variety of random but usually Da-Glo colors. Few if any surface features are visible from space.
      • Nevertheless, the surface of most extrasolar planets are largely covered with a similar beige sandy soil. The planets have many rock outcroppings, and remarkably, the rocks are almost exclusively comprised of a polystyrene polymer.
      • All extrasolar planets harbor life. Almost all of them have a climate and flora very similar to the desert regions of southern California.
      • Most extrasolar planets have an unexplained energy field emanating from some point on the surface.

      You misread the article.

The habitable planet would be further away, in the habitable zone. Check out the picture.

    Cats and dogs are sentient, as the term is generally used. The term has sometimes been borrowed in science fiction to denote human-like intellect, but given its well-established use, that's a poor borrowing (better is the more common "sapient" or, as a noun, "sophont"; the latter isn't a word in general use but has an appropriate etymology, the former is in general use, but in a way that supports the pseudo-technical extension of its meaning to this use better than "sentient".)

    At first it says that a Hot Jupiter would make a habitable planet, but then it says that the Hot Earths it makes will be uninhabitable.


    If you read the article, it's a bit more clear than the summary apparently was for you.

    The article is saying that as Hot Jupiters migrate inwards, they temporarily disrupt the belt of debris in the habitable zone of a forming solar system. Then, after the Hot Jupiter has passed through, that debris has a chance to coalesce into habitable, Earth-like planets. In addition to this (and this is where careful reading and good reading comprehension skills come in handy), Hot Earths can be formed when Hot Jupiters push some material forward with them during their inward migration. From the article:

    "We now think there is a new class of ocean-covered--and possibly habitable--planets in solar systems unlike our own," Raymond said.

    The simulations also showed that rocky planets known as hot Earths may often form when hot Jupiters push material forward during their inward treks.

    Jeebus, buddy, why start with love? Why not just start with randomness? You have enough of that, you automatically have everything else you mentioned. And you have an infinite amount of that. Any particular slice of that randomness might define a starting condition, a set of rules to eveolve the starting condition, or a point along that evolution.

    Love is such a hokey place to start. Why not shoot higher? Start with awareness, or consciousness, or reference, or division or some other abstract concept that hasn't already been done to death. Love. Fegh. I did that one when I was four. Not that it's not nice and all, but starting from there necessarily leads to some mind numbing inconsitencies when you think far enought through the implications.

    Here's a fun one: You start with a lack of any definition whatsoever. This lack of definition necessarily includes all possible definitions as well as all lack of definition, to say it doesn't is to define it. So zero is not nothingness any more than it is the lack of nothingness. Some definitions imply a set of laws and a starting condition, also conveniently contained within our infinite undefined nothingness. Zero becomes one because it needs something to refer to it, and one becomes two for the same reason. The Ain Soph becomes the Way, which becomes Yin and Yang. Yang is nothing, refering to everything. Yin is everything, refering to nothing, and the way is the laws which move the two forward, becoming the ten-thousand things (or the world, as it is called in Buddhist philosophy.) I just made that one up off the top of my head.

    Honestly, you kids these days, you think you invented this shit. Gah, stinks of the dharma, doesn't have a teacher to indoctrinate him into a particular path: this is what we get. "It's all love!" Well, you know where that leads?

    God is love.

    There's a big difference between a chemical compound that has certain effects on humans and a parasitic mold that uses human bodies as a host, as in the GGP.


    It works just as well the other way, too: Why is it that healthy people don't get digested and putrefied by bacteria, when corpses will be broken down in a few weeks or months? Because the human immune system has been refined over a long period to recognize and fight the particular organisms that continuously try to invade and digest our bodies. So why would you expect our immune system to know how to fight off a completely alien lifeform that it's never experienced anything like before? Hell, lots of people get sick just flying to another continent, let alone another ecosystem.


    Keep in mind that in the eat-or-be-eaten scenario, the eater need only know how to digest and make use of the opponent's raw materials. The eatee has to know how to disable or kill the attacker, a much more difficult problem. Without our immune system, we're equivalent to 150-pound bags of rich growth medium...
