An "effectively" infinite distance between two bodies should be possible due to cosmological expansion, right?

That happens at only about 800Lj in an otherwise emty environment. (an ejected star from a galaxy for example) r=sqrt(m*G/H) from G*m/r^2=H with G as gravitaion konstant, m the solar mass, r the distance and H the Hubble constant, if I didn't make a mistake here.

@michaelskywalker30894 жыл бұрын
Statement intrigues as reasonable equivocation. The minimum escape velocity of the smallest and most common gauge particle depends on the minimum or threshold of radiative pressure this single photon can exert. Since photons have zero rest mass then the minimum amount of force required depends on the threshold of kinetic energy. If the photon does not meet this kinetic energy minimum then it cannot escape a given gravity well. ........ Take the interior of our solar system's star, Sol for example. It is famously noted that photons from the interior cannot exit the surface for centuries, but what if a photon had a high enough momentum to escape the radiative pressure surrounding it as well as the gravitational well and nuclear convection pressure [magnetic flux etc] . If the velocity vector pointed up this high energy photon might escape the Sun in a single instant!

Weeeelll...this detail of the video is technically wrong. Or at best, misleading. In a static universe, its true that gravity is infinite, but our universe isnt static; its expanding. Gravity waves, and thus the effect of gravity, move at the speed of light. That means parts of the universe moving away from us faster than light due to space expanding dont exert gravity on us. Everything outside of the observable universe is outside of our gravity, so the border of gravity is the observable universe. Basically, if you cant theoretically see it, your gravity doesnt affect it. Interestingly, this also means that the gravity of an object doesnt affect us instantly, only when its light reaches us. So Earth is being pulled via gravity not to where the Sun is right now, but to the point in space it was 8 minutes ago.

A solar system could technically be an entire galaxy or group of Galaxy's. Our sun is orbiting Sagittarius A Star, as is the entire galaxy, and I'd wager that the barycenter of the galaxy lies within the event horizon of Sagittarius A.

Alex, I've read that the new Moon (when it's directly between the Earth and the Sun) is pulled by the Sun with more force, than it's pulled by the Earth. Could you please prepare a video on this Earth/Moon/Sun dynamics?
@mattg81164 жыл бұрын
I don't think that's quite true, that would place the moon beyond LaGrange point 1, at least when accounting for orbital mechanics. Both the earth and moon are under considerable gravitational force by the sun, and though the moon orbits the earth, it can also be said that it orbits the sun with earth. Regardless, each time the moon is between the earth and sun is balanced by each time it is opposite to both the earth and sun.

ASTUM QUESTION: Would it be possible to have a solar system outside of a galaxy, and if so what are the challenges to us ever finding it? You inspired this thought in your video where you said "stars could be ejected outside of their galaxy" - and presumably the planets that orbit it may be ejected as well, although their orbits would likely be perturbed

@piranha0310914 жыл бұрын
Here's a fun fact: if you take, on one hand, the Planck length, the smallest length that is meaningful to physics, something absurdly small even by subatomic particle standards ; and on the other hand you take the size of the visible universe, the largest distance it makes sense to consider in physics ; the geometric mean of both is 0.12 mm. That's the boundary between the microscopic and macroscopic. The center of the universe, in a way. The width of a thin thread.
