    You try getting video from something that, within 30 minutes, accelerates to 18000 MPH. Literally, it will change what frequencies you even have to listen to, let alone the crazy amount of interference experienced during the process of exiting thr atmosphere.

    Literally, the air compressing and ignighting against the shell of the space craft itself will produce crazy signals, let alone every other effect.

    There is a reason it took even SpaceX over a decade to keep signals remotely intelligable with their booster recoveries, let alone launches aimed directly at the moon.




  • For a serious answer, there’s a whole process you can follow. It’s basically going from minimum exposure up through eating a small bit of it and waiting multiple hours to days between steps. If any show signs of being irritating or worse, don’t eat/use that plant. It’s slow enough that if you had to rely on it for finding your sole source of food, you’re going to have a rough, hungry time.

    Something like:

    1. Rub a little on hardier parts of your skin, wait and see.
    2. Break up the plant to expose more of it and rub that on a small patch, wait and see.
    3. Try it on more sensitive skin areas, wait and see.
    4. Try holding a bit in your mouth, spit it out. Wait and see.
    5. Chew some up, spit it out and wait and see.
    6. Eat a tiny amount, wait and see.

    I’m probably forgetting some steps, too. It’s genuinely very slow.

    Worse yet, there are plenty of plants/fungi that would still fuck you up or kill you doing it this way, so the OP still has a point.







  • The bigger problem is Earth is gooey at scale. Seriously, the mantle, which is most of Earth’s mass, is gooey rock. “shattering” as if it were solid simply isn’t going to happen. Most of the Earth is like thick caramel or worse as far as “shattering” is concerned.

    The best you could hope for is something like how the moon formed; an impact (very) roughly 10x less than the gravitational binding energy of the Earth itself (which is crazy in and of itself!). If you’ll note, the Earth ‘survived’ that impact, but was forever changed in significant ways.

    What’s even crazier, is that Earth had single celled organisms growing on it less than 500 million years later! For reference, the oldest mountain ranges are 2-3x older in relative terms.


  • A very large asteroid (>500km) would be a good attempt at ‘shattering’. (much like how the moon formed, in theory) Otherwise, a “small” black hole or other cosmic-scale forces would do the trick. A near by blazar would easily sterilize the planet if it were aimed at us, but there are none such objects we have yet observed. (luckily)

    The sun itself is easily capable of smearing Earth out, but the real question is “how?”. Even a crazy CME aimed directly at Earth would barely be able to wipe out technology, let alone life. A close call with another solar system would definitely stand a solid chance of wiping out life as we know it, but it wouldn’t necessarily be terribly quick.

    It’d be very predictable in that we’d be able to see another solar system coming for decades/centuries/longer, and many changes would still be longer than a human lifespan (outside of the final ‘kick’ event, which could be over in a matter of weeks/months and leave the surface freezing and potentially devoid of much atmosphere).



  • lol no. Genuinely, no. You are a clueless fool playing with numbers you cannot comprehend.

    Even earthquakes within recorded history have released more energy than 10 gigatons. By an order of magnitude.

    You are seriously a fool that does not begin to fathom the scale of Earth.

    Look up how much energy the Valdivia, Chile earthquake in 1960 released and get back to me. Again, you petulant child failing to comprehend the topic…



  • Correct. Even with perfect conversion of mass to energy, it would still take converting the mass equivalent of a 16+ km asteroid directly into energy.

    Even antimatter explosions are not anywhere near 100% efficient. They produce many subatomic particles with high energy. Much of the reaction will quickly (on the order of 1x10^-16 seconds (… ok ok pions take 1x10^-8 seconds to decay, which is much longer)) settle into neutrinos or electrons. About half of the energy would nigh-instantly convert to neutrinos. Neutrinos will not care or contribute to ripping Earth apart even if they’re produced in the Earth’s core.
