Bit of an awkward scale for a ruler, but I can sell you one from -6.6666666… to -6.65 goobs.

0 K is like when there is 0 heat basically, while celsius isn’t. Imagine a unit for distance called “goob” where 0 goobs is 100 m and 1 goob is 115 m. In that case the goob unit would behave differently than a meter when you multiply and divide because 0 of the units don’t actually correspond to “nothing” in a physical sense. That’s exactly how the Celsius scale is, with zero being placed somewhere arbitrarily, not at a physical zero.

Yeah it probably is, my comment was really about raw deltaV numbers without using gravity assists.

Yeah, you would only need to burn a little bit more on your initial burn, that’s why I said the cost would be similar.

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.

It’s just not true though, unless you do an out then in maneuver.

No that’s not really the case, the earth will be destroyed.

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.

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.

Probably not, but the people who just got a job maybe would.

I mean if a state removed the TSA and spent the money on something else, surely they could use the money to create as many jobs as they removed but in an actual useful field.

Yes, it’s the avocado man himself in the picture.

If the arm can bend, the car and the magnet could move towards each other until they come together, moving the car at max a few centimeters. If the arm doesn’t bend, the car is pulled as much forward as the magnet, and therefore the arm and in turn the car itself, is pulled forward, leaving the whole system stationary.

No, because if it’s a proper planet it will clear its orbit.

Yes, but it’s not guaranteed that it will.

As someone who does know about this field, and absolute despise Musk, that’s not quite true. SpaceX is very successful thanks to help from the US government, and despite the influence of Musk, but also because they are a team of very competent people who have actually innovated and pushed the boundaries of launch vehicles. To say they have nothing going for them and are being propped up by the government is not at all accurate, and they have been much more succesful than traditional government contractors.

Do you accept my balloon? ;)

Well, not alive ones.

That’s like saying a burger is plant based since the patty and cheese are the only non-plant based parts. That’s ridiculous and just not what the word plant-based means.
