@astro_samira_b@Kaptain_Europe Ce n’est d’ailleurs pas le regime de fonctionnement du moteur mais une phase transitoire
Si c’est dimensionné pour je vois pas le problème
Bears laughed, doubted, and called it over.
We stayed, we built, we kept our conviction when it wasn’t popular.
Now momentum is shifting and the same voices are going quiet.
That’s the difference.
That’s why we $BULLIEVE.
$BULLIEVE
Everyone waits for confirmation.
By the time they feel safe, it’s already priced in.
Conviction is built before the crowd.
Not after.
I’m positioned.
I’m patient.
I Bullieve.
And you — do you Bullieve?
@elonmusk It is super dumb to forget that the Sun is 149,600,000 km away from Earth and that the surface of a sphere grows with the square of the radius :) (so the Sun’s energy radiates per m² then).
For a man this wealthy I can’t understand why you are so interested in solar lobby money.
@TechSpatiales Bizzare de concevoir un moteur optimal pour aucune altitude non?
Est-ce tant négligeable que cela?
Sin(Angle de sortie du gaz)*masseparticule*acceleration est la force perdue non?
@SosageMcBiscuit@ApoStructura@hoseja@AwesomeBeast321 Because Stefan–Boltzmann formula is for what an object radiates but this object also absorbs radiation.
On earth your object radiates something but also absorbs the radiation of the earth itself and everything else…
We can then rewrite the formula with T ambiant or env in it.
