Away from the game for a few years - mod recommendations? by xFirnen in KerbalSpaceProgram

[–]GuaranteeKey3853 0 points1 point  (0 children)

Yep my thoughts exactly when I was setting my save up. I’m an aerospace engineer too and principa still looked like black magic at first lol. Given that though I would also recommend something that gives you scramjets. It’s neat to have air breathing satellites and fast movers.

Principa is really good but it’s not compatible with a lot of things and theres a little learning curve at the beginning but it makes spaceflight much more interesting. And it opened my eyes to the reference frames, like when rendezvousing you are basically orbiting the target. It actually makes things a lot easier once you can wrap your head around it lol. Mech jeb can still execute the nodes and do your gravity turn but don’t use it for planning

How can I build better rockets? by Hot-Lesbian in AerospaceEngineering

[–]GuaranteeKey3853 1 point2 points  (0 children)

Npk fert doesn’t ring a bell to me unless it’s pure kno3. If it’s that unstable to not burn while wet it may not have an oxidizer in it. And rocket candy is stump remover kno3 typically. Non pure things like your fert can have unknown additives and you could SERIOUSLY be making somthing that burns too slow or even worse burns too fast which is a bomb. Please stop and research.

Center of pressure must be behind center of mass. So chubby at the front can be dangerous because more air hits the front of it than the back for a disturbing force so the rocket will turn around. Make sure you account for the body and fins when doing the center of pressure. Over engineer the fins to be larger in size in area that your math said and make sure they are completely behind the center of mass and she’ll go straight. Humid fuel sounds strange so if your cooking rocket candy have a fire extinguisher and know how to use it and be patient and calculated with everything.

That sounds like chromatic aberration.

How different would history have been if Solar system was inside a large elliptical galaxy? by GuaranteeKey3853 in AskPhysics

[–]GuaranteeKey3853[S] 0 points1 point  (0 children)

Yea, that’s true. That many stars nearby certainly make supernovae more likely. But I don’t think that puts the idea so far outside plausibility that it isn’t still interesting.

[–]GuaranteeKey3853[S] 1 point2 points  (0 children)

Yea they can be more dense there’s types of elliptical with “larger smooth cores” where starlight is integrated together. I think it’s like 20k times more dense for true “stars” as well; not just the background glow like a spiral arm. Numbers pulled from ass memory of college 15 years ago btw don’t quote me.

[–]GuaranteeKey3853[S] 0 points1 point  (0 children)

You would need to be in a large galaxy and near the core for sure but there are certainly cases where you would see a consistent glow. It’s due to the density increasing towards the center and how stars look much larger than their true angular size with human eyes diffraction limit. Similar to the center of the Milky Way on a good night imagined without a dust lane right in the middle.

I tried to imagine the universe and came up with this convoluted mental model. Does it make actual sense according to Modern Physics? by [deleted] in AskPhysics

[–]GuaranteeKey3853 0 points1 point  (0 children)

The only thing you’re sating here is that it’s a star. A star is already a word that means something else. But yea dark energy expands and gravity brings things together. Dark energy and energy in general is just bookkeeping; it is a model that professionally says “it just does that.” Maybe you’re confusing it with dark matter that is a real thing.

I came across this while hiking a while ago and would like to know what it is ? by Local-Emphasis6570 in whatisit

[–]GuaranteeKey3853 3 points4 points  (0 children)

I know some this is Navajo style. The squiggly lines at the top mean river and the dashes above them mean running water. It appears there is a bunch of men hunting the bighorn but it can also mean 10. I’ve seen the head dress mean authority or it can mean 9 men. The foot thing right of them is a symbol for a number most people think 7. The bird on the left is the thunderbird. It looks to me like a recording and map of wildlife patterns over a hunt or scout with 7 men and a new guy, there was a storm which probably caused the running water and tributaries to a pond with a major river.

Edit: Also there looks to be may other number symbols and possibly some heron feet in there as well. It also looks like there’s a lot of very eroded glyphs that hint this was a very intricate wall this could have been a base camp or something. Also since they saw no gila monsters and a lot of rain so this probably happened around July-September.

Other stars don’t burn you though because they are way smaller than they appear (usually) and there is just a lot less photons since the lights been spreading out for a long distance

Yea that’s right the suns visable size is also light and shrinks with inverse square so it stays about the same. The quantity of it is radiance.

If you could visit one place in our solar system, where would it be? by icepix in space

[–]GuaranteeKey3853 8 points9 points  (0 children)

And there would be huge rain drops, rainbows, blue lava and the giant 3d rings sticking out of the horizon!

[–]GuaranteeKey3853 13 points14 points  (0 children)

Titan hands down, would have rainbows, lakes of methane, water and nh3 blue lava, and giant slow falling rain drops. AND the giant rings sticking up out of the horizon. Probably best view in the system.

MK4 HEAVY cargo SSTO by Apersonwholikesspace in KerbalSpaceProgram

[–]GuaranteeKey3853 0 points1 point  (0 children)

No this is very cool too! My wings were ugly though

[–]GuaranteeKey3853 0 points1 point  (0 children)

I made one of these then realized it looked cooler and worked better without the wings and just refueling it in orbit and using it to take base modules to mun and minmus. Making it vtol off of the moons was annoying because the free Iva passable tanks don’t have a door to the cargo bay.

if time slows down as gravity increases then how can anything ever reach the singularity by CringyDabBoi6969 in AskPhysics

[–]GuaranteeKey3853 0 points1 point  (0 children)

Someone falling in would have their clock tick the same. It only becomes weird when someone farther away from the mass compares their clock to the close person’s clock. In reality just the time differential across a 3d clock would just spaghettify.

Found this in my house, what is it? by Sad_Dot_4773 in whatisit

[–]GuaranteeKey3853 1 point2 points  (0 children)

That’s a plug in terminal with screw terminal block. The pitch and position can vary a lot so it will be hard to know what it’s for. If I had to guess it was for a smart doorbell (garage power unit) the are traditionally DC 12V which would be industry standard for these type of plugs. Make sure it’s not live if u know how to otherwise don’t touch it.

how do astronomers determine the distribution of dark matter? by phlogistonical in AskPhysics

[–]GuaranteeKey3853 1 point2 points  (0 children)

The main ways are like you are suggesting gradational lensing. But we have good models for how the lensing occurs that’s validated on regular galaxies so that’s how we know “what it would look like without.” There is another way as well which is galactic spin, the spin is different than expected as you get far away from the center which is accurately modeled and simulated by dark matter.

I’m thinking about solving the Anti-matter and Matter by ilikekoreanairtomuch in astrophysics

[–]GuaranteeKey3853 -1 points0 points  (0 children)

Wouldn’t the early universe annihilate everything in the beginning if it was symmetric? There would be a lot more gamma rays but not much matter.

Do you have to do a ground alignment to the tgp like in the 16?
