Which more likely explode first?

[info]

Are you worried the Sun exploded eight minutes ago too? Stars regularly explode. Few late sequence stars have many planets 'left'. Planets are also known to explode. Which do you think will explode first? Which one, and why? We need interstellar life now.

Where's the evidence that planets have been known to explode?

You mean in fiction books?

[chaz wyman]

There is nothing explosive about the earth. There is a chance that some large object could crash into the earth but that is a different question.

However the Sun will at some point explode, as many other stars explode.
According to the Theories of astro-physics it is not though likely to happen any time soon.

While ancient natural fission sites have been discovered on the outer part of Earth (Oklo in Gabon, Africa), it seems unlikely that even among the number of extrasolar worlds there would be one with freakish circumstances in its core that could allow chain-reactions of any kind to be organized enough to produce a major explosion powerful enough to break that planet apart. And a gas-giant planet bordering on being a proto-star would simply become just that: blaze as a short-lived sun if fusion processes anomalously commenced in it without the necessary mass for gravity to compact that startup.

The asteroid belt wasn't a planet that exploded. It's just leftover material that never aggregated into a such large body, due the influence of Jupiter's gravity or any number of other posited ideas. Even after such a "shattering", the Moon would be evidence that the debris reassembles back into a body rather than distributing out into a belt around the sun (if going by one theory of the unusually large satellite's formation, where Earth and a Mars-size body collided back in their earliest days and the expelled debris from the collision became the Moon).

The sun doesn't have enough mass for a supernova-type explosion. Its fate is to become a white dwarf star before it fades altogether. That evolution will occur in stages over billions of years, with plenty of slow warning signs of what is to come. One of those phases is where it will expand in size to at least the orbit of Venus (becoming a red giant star), eventually losing most of its gases in a series of pulses. But that demise of the Earth will already be irrelevant, since a few billion years before this temporary expansion, the sun will have increased in brightness enough to boil off the oceans and water vapor of Earth into space (Venus and Earth really will be sister or sibling planets, then).

Keep telling yourself that. Everything's safe. We're not on the cusp of infinity....

[Arising_uk]

Well, we're certainly upon the cusp of something but I can't tell if its insanity or inanity.

Could you describe the general differences between planets that explode, and planets that do not? The general conditions for planets exploding?

No, you know why?

Because we have no evidence for planets exploding nor any good theory as to why they would.

The only place such a thought could come from is fiction.

Well, if you can't wait that long for human extinction, then there are much more likely circumstances to fret over than the sun or the Earth blowing-up naturally. Or even exploding with the aid of space aliens having terrorist agendas.

You mean the asteroid? What about it?

You think there is an asteroid big enough to make the world explode? If so I doubt it as it'd be a moon somwhere.

But lets say there is, is this the same as your suggestion that the Earth will explode like some stars do?

Is this what you meant? That there is a probability that we could involved in an extinction event?

Part of the reason for the planetary crisis of late is that there are wildly many huge objects whirling around. There are thousands of planets. Also I'm imagining the nuclear core of Earth exploding? Core theory is conjecture mostly. Why is there life on Earth? This is why... There are billions of Earth-like planets some guess, but what is different about Earth is that it has lasted for 4 billion years of life and not been whipped out. Any number of events could have almost done that, never mind asteroids, whole galaxies collide. So the time space of stability is very unusual by stellar standards of constant mulching and sudden radical events. If humanity, or life is to survive we need to desperately apply the principal of not putting all our eggs in one basket here. One Sun burp and we're starting again from atomic star dust. The surface of a planet is very vulnerable... exposed to interstellar space --

But lets say there is, is this the same as your suggestion that the Earth will explode like some stars do?

Perhaps the subterranean races will have a nuclear war, not realizing we are up here and blow the Earth apart? Deepest mine is only 8 or so km; deepest drill only 25ish if I recall. Whole worlds might be down there. Life started deep underground off the heat of the Earth as the accretion disk solidified, if not in space prior, because life was going as soon as the Earth solidified already, it's a sort of crystal. Green-life came after cells in general; the smallest cells are found in deep core-samples; deep-sea life that lives off chemicals is probably not "extreme", but the original life, later switching to running off the heat of the cooling Sun, leading to heterotrophs and later machines. Therefore, life in deep hot underground caverns, 1000 miles down even, could be.

Is this what you meant? That there is a probability that we could involved in an extinction event?

The retard capitalists have already destroyed the Earth for life, the check is in the mail, and the machine-men will keep their word. Domes is the answer. From there leaving Earth will be no question, why stay in a 500 degree methane hurricane?

There are two problems: 1. will the environmental collapse happen so fast domes or underground shelter won't even be built fast enough once the winds shift and the heat or cold move by 1000 degrees, or will be poorly prepared, lasting maybe a few generations? 2. Much more disturbing in the end... What is the long-term potential for metabolism a) can domes produce enough labor to reproduce themselves, and related to the oil crisis problem: b) an even deeper strata of crisis at the molecular level: once we destroy all life on Earth and burn all the oil and coal, how are we going to get organic molecules necessary to build our bodies with? All those molecules took billions of years of sequencing and star-light power, it's a lot of energy up in smoke we can't easily get back into organically usable forms.

Well far be it from me to dis the afflicted and not that I don't think things may go to hell in a handcart, nor that I don't enjoy distopian sci-fi or lunatic metaphysics, or that we could be made extinct at any time from a variety of external causes, but you are barking mad!!

As what odds do you think any of these things will occur with the short 70-80 years of your life? So what matter to you such thoughts?

[thalarch]

. . . but what is different about Earth is that it has lasted for 4 billion years of life and not been whipped out. . . . So the time space of stability is very unusual by stellar standards of constant mulching and sudden radical events.

If we were in the crowded interior of the Milky Way rather than its rural outskirts, there would be more violent events from neighboring stars as well as their gravitational disturbances. But we're in Compo's, Clegg's, and Foggy's stomping ground.

Perhaps the subterranean races will have a nuclear war, not realizing we are up here and blow the Earth apart?

Just want to make it clear that I'm not easing slowly and politely toward the exit door because of this high-tech progress that Pellucidar seems to have made since the days of Edgar Rice Burroughs. Even if they were still living in the stone age, that union of cave men and dinosaurs and a hollow Earth would still be unholy.

I had to retro to something like "unholy" above because in this era of the New Prudishness it is a concept like "unholy" that an ascription of "incorrect" would probably be more applicable to rather than such chimera marriages that mingle the anachronistic with phlogiston-type fare. For in the eyes of the New Prudishness these strange unions are probably more like a testament and celebration of how we can indeed overcome our differences in the global sisterhood.

The use of sisterhood above being more correct than brotherhood when it refers to something positive and good. Cuz a bunch of bruthas living in harmony would suggest a radical egalitarianism achieved via patriarchy, where the muthas is being oppressed by the bruthas. Whereas the "nice gender" would never do the inverse.
