Voyager 1 entered interstellar space — but it has not reached the Oort Cloud

Crossing the heliopause in 2012 did not mean leaving every gravitationally bound region of the Solar System. NASA estimates Voyager 1 will reach the inner Oort Cloud in about 300 years.

ENGLISH · PARTICLE PHYSICS · NEUTRINOS

The ghost particles that changed physics: why are neutrinos so incredibly light?

Neutrino oscillations established that the minimal massless-neutrino Standard Model is incomplete. The seesaw mechanism is one influential but still unconfirmed explanation for their tiny masses.

ENGLISH · RIGID-BODY DYNAMICS · DZHANIBEKOV EFFECT

Can Earth Suddenly Flip Over? The Dzhanibekov Effect Explained

Why rotation about a rigid body's intermediate principal axis is unstable, why the 1985 Salyut 7 wing nut flipped by 180°, and why that does not mean Earth is about to turn over.
