What? Do you say what installer cleared up the addons folder? This is impossible...
Very possible. Just happened to me. :/
You should have read this!
Quote SpaceEngineer ( ) Ok, SE installer indeed deletes ALL files and folders in the installation directory before install. I fixed this in installer script, it will not do this in future
Only two posts below.
Don't forget to look here.

| JackDole one of the note you provided was that for SE 1 AU = 149597870.691 km
This varies from the current value of 149597870.700 km by definition.
Which albeit is only a small variance (6.016e-9%) it does add up on larger distances and increases cumulative errors.
So I am wondering, if other constants vary from the current adopted values in SE
G 6.67408E-11 m^3 kg^-1 s^-2 CODATA 2014
lyr 9460730472580800 m by definition
pc 30856775814671900 m by definition
The following also vary based on information in various threads
Julian Year 365.25 days of 86400 seconds definition
1 SE year = 365.24218985 days indicated in the Planet mod thread. (this looks like the tropical year)
can anyone tell me what does and doesn't vary and current values so I can have my calculators up to date for SE 0974 calculations.

| abyssoft,
Astronomy/Mathematics - Wikiversity has this value:
Code 1 AU = 149,597,870.691 km
The programs that I use - 'ConvertAll' and 'SpeedCrunch', provide both 149597870691 m.
I do not know what value SpaceEngine used.
SpeedCrunch:
Code
Gravitational constant: 6.67408e-11
Speed of light: 299792458 m
Light year: 9.4607304725808e15 m
Parsec: 3.08567802e16
Julian year 365.25
ConvertAll:
Code
Seconds per day: 86400
It would be good to know what values are used by SpaceEngine.
SpaceEngine uses 365.24218985 days for the length of a year.
Don't forget to look here.

| from IAU Commission 25 Resolution B2 (which was ratified) it has the same value as I was using Astronomy/Mathematics - Wikiversity seems to be out of date.

| It may be that this is the 'official' value. In any case it is a rounded value. I think more accurate is 149597870691 m.
But as I said, I would use the value that is used by SpaceEngine. If I knew it.

| JackDole, how did you figure out SE's number of days in a year?
3.14% of all seafarers are PIrates.

In this thread: MOD - Creating a Planet 0.972
Under Orbit:
Code
Epoch - epoch of the periapsis passage in Julian days.
Period - orbital period T in years (useful for elliptic orbits). 1 year = 365.24218985 days.
MeanMotion - mean motion n in degrees per day (useful for parabolic and hyperbolic orbits).

| Wolfram|Alpha gives 33 significant figures. No idea where do they get this value from though and I think we "should" stick to the defined value.

| It seems that some of the stellar black holes have anomalously high masses. Could it be related to most red supergiants having extreme masses?

| Huh, red supergiants really got more massive in RC3. Look at the star I posted here. The screenshot is from RC2, but it's still there, with most parameters identical save for mass (now nearly 2250 solar masses) and rotation period (over 32 years in RC3).

| Poor Vladimir... I hope he's reading all these reports, because if he did it at once, he would have an heart attack.

| You just gave me a link to RC3 which I already have. I wonder what is coming after that.
