C’est quoi l’horizon des évènements d’un trou noir ? C’est la frontière qui protège le reste de l'Univers de ce qui se trouve dans le trou noir. Rien de ce qui se trouve à l’intérieur de l’horizon ne peut atteindre l’extérieur. Salukes #science #physique #profbucella #lasciencepeuttout

Où sont-ils tous ? Fermi parlait des extra-terrestres. Il devrait y en avoir pleins, or on ne les voit pas. C'est le paradoxe de Fermi. Salukes #science #physique #profbucella #lasciencepeuttout

La phrase est construite sur un piège logique. Quand on dit « fermez la porte, il fait froid dehors », on ne prétend pas que fermer la porte va modifier la température extérieure. On veut simplement empêcher l'air froid d'entrer dedans.

En 1+1 dimensions (une dimension spatiale, une temporelle) et sans matière, la relativité générale devient triviale. Le tenseur d’Einstein est identiquement nul, il n'y a pas de degrés de liberté gravitationnels propagatifs (il n'y a pas d'ondes gravitationnelles), pas de gravitons.

L’astronaute Victor Glover avait oublié que la caméra était allumée dans la capsule Orion. Il s’amusait à tourner sur lui-même. Cet exercice en micro-gravité montre bien la conservation du moment angulaire. En l’absence de couple extérieur, le vecteur L reste constant en direction (axe rotation).

D’où viennent les marées de la Lune ? La question est plus subtile qu’il n’y paraît. Elle sera résolue because la science peut tout (et la physique surtout). Salukes #science #physique #profbucella #lasciencepeuttout

Si vous n’avez rien compris au film Tenet, c’est normal. Ce film est impigeable. Voici l’astuce de la science pour revoir le film et le comprendre. Il faut tenir compte de l’entropie. Certains vivent l’entropie dans le bon sens, d’autres vivent l’entropie à l’envers. Salukes #science #physique

Comment reconnaître la face cachée de la Lune ? Des cratères à perte de vue, aucune mer lunaire, les taches sombres qui caractérisent la face visible. Sur la face visible, c’est pas qu’il y a moins de cratères, c’est que les mers les ont recouverts. Salukes #science #physique #lasciencepeuttout

Les astronautes d'Artemis II vieillissent-ils moins pendant le tour Terre-Lune ? Intuition immédiate : vitesse → relativité restreinte → vieillissent moins.

Today, we introduced the Public Lands Integrity Act to stop federal public lands from being sold off to fund Republican’s spending sprees. This bill ensures that public land sales cannot be fast-tracked through budget legislation, keeping our public lands in public hands.

Ever seen a timberdoodle dance? “Timberdoodle” is another name for the American woodcock (Scolopax minor) — other names for this bird include the bog chicken, bogsucker, and mudbat. It is such a weird animal. Meep! #wildlife #bird #birds #nature #science #wildlife #woodcock

Orban copied Trump. Trump copied Orban. And in the end, the people of Hungary chose democracy and the rule of law. As will happen here too. But only if we do our work, like they did.

Replying to @mford71 Such a good question! Probably it would be OK, but it depends on the provider, plus it must have the right measurements etc. Give your provider a call if you're not sure.
