It's definitely harder to decay the orbit into the sun directly than it is to get to escape velocity. But to play devil's advocate, there is probably a way to get them into the sun while being a similar cost to escape velocity. All you need to do is burn prograde to a super high aphelion, ride all the way out there to Pluto or whatever and then do a small retrograde burn to bring your perihelion inside the sun's photosphere. When you then get back towards the sun years later you would slam into it with a sick velocity that I think would be worth the decades-long wait.
Technically there is no boundary, it's atmosphere all the way in. But what we might call the "surface" is the photosphere. That is where the density becomes "low" (read not insanely high) enough that light can escape in a free path.
The sun has an atmosphere so there are soundwaves coming out of it. It's actually all one big atmosphere getting thinner and thinner as you go out just like ours.
Depends on where they met each other. If they for example fell in love during the main event of a trip to the north pole, that would change things a lot.
Is this actually real? If so the brain worm thing is not even a joke anymore, they must have done some serious neurological damage because that's messed up.
Good on her for turning out to be what seems like a very reasonable human being, must be hard coming from someone like him, but I presume he had no part in raising her so maybe it makes sense.
Website for pirating books. A godsend for me during university, where I saved 100s of dollars per semester, while getting the books in a digital format which I prefer.
Ok, there are two apartheid genocidal regimes, but what else have the Romans ever done for us?
