That's no way to do science. We should blow up Jupiter to see if it kills us and rule out our being mistaken. Honestly, you "people", making simple things unnecessarily complicated.
>>16992574 Kind of hard to prove. We can't just remove both planets and rewind time by 4 billion years to run the experiment again.
We can definitely say more asteroids would hit Earth but that's the only certainty. There would be an increased chance of asteroids the size of the dinosaur killer hitting, which would mean there'd still be life but evolution would happen differently, so maybe no humans.
Let's invert the perspective. Every observer in every possible observer supporting location must necessarily feel like they are an observer in a location which supports observers. Or..? Not sure what alternative there is. Some observers think they're fake and or gay?
>>16992632 You do realise that's bullshit right? The arc size of the sun and the moon are not identical, there's about a 3% difference. Every year the moon gets further and further away from the Earth. Wait for several hundred millions of years and solar eclipses won't even be a thing. This only "coincidence" is we happen to live in a time period where they happen.
>>16992655 Nigga you can't even solve a 3-body problem and you gonna try to make assertions about an n-body problem cast forward into 10^9 years from now. U retarded
>>16992655 >Every year the moon gets further and further away from the Earth. Wait for several hundred millions of years The world is 5786 years old, all the geometry is valid.
>>16992670 N-body is irrelevant. This is simply due to conservation of momentum and the fact the moon is tidally-locked. The result of which is that the moon moves about an inch away from the earth each year. This has been measured by bouncing lasers off the moon's surface.
Someone did a study of the stability of the solar system and it was found that while its a chaotic M body system, the interactions are so weak it will take billions of years to see real effects. Most of the effects cancel out, jupiter pulls from one direction this year, then next year from some other direction. The force is very weak as well and it cancels out almost perfectly. The calculations are that you can expect changes in orbits on a scale of billions of years
>>16992834 That's because the solar system is practically a 2 body system with sun containing 99.9% of the mass while Jupiter contains basically all of the rest. Things only get chaotic on a short time scales when the masses are more even.
>>16992655 for some reason many people don't know what annular eclipses are it's no surprise that in the continuum of angular sizes of the moon in its orbit that twice an orbit it matches the sun perfectly, since at its extremes its both smaller and larger than the sun
>>16992605 >We can definitely say more asteroids would hit Earth but that's the only certainty.
Can we? How exactly is Jupiter supposed to "shield" earth? Yeah it got big grav but why does that deflect asteroids from earth rather than pull them from the outer solar system towards earth?
