On reproche souvent aux scientifiques de ne pas participer aux grands débats qui animent notre société, préférant plutôt rester cloîtrés dans leurs laboratoires. Or, de nombreuses barrières s’élèvent contre cette participation. Tout d’abord, les scientifiques travaillent dans des environnements de plus en plus spécialisés. Dans un tel contexte, où ils ne parlent vraiment qu’à des gens qui s’intéressent aux mêmes questions pointues, ils se sentent souvent incapables de se positionner sur des sujets qui recoupent leurs expertises, mais qui couvrent aussi beaucoup plus large.

Yoda’s greatest display of raw power in the original trilogy came when he lifted Luke’s X-Wing from the swamp. As far as physically moving objects around goes, this was easily the biggest expenditure of energy through the Force we saw from anyone in the trilogy.
The energy it takes to lift an object to height h is equal to the object’s mass times the force of gravity times the height it’s lifted. The X-Wing scene lets us use this to put a lower limit on Yoda's peak power output.
First we need to know how heavy the ship was. The X-Wing’s mass has never been canonically established, but its length has—12.5 meters. An F-22 is 19 meters long and weighs 19,700 kg, so scaling down from this gives an estimate for the X-Wing of about 12,000 lbs (5 metric tons).

This is a beautiful question, in a small part because it’s an interesting thought experiment with some clever math, but mostly because of all the reasons it couldn’t be done and wouldn’t work. Right off the bat; clearly a hole can’t be drilled through the Earth. By the time you’ve gotten no more than 30 miles down (less than 0.4% of the way through) you’ll find your tunnel filling will magma, which tends to gunk up drill bits (also melt everything).

An international team of astronomers has reported the discovery of the strongest magnetic field ever found around a massive star. NGC 1624-2, also known as 2MASS J04403728+5027410, is an O-type star with a mass of 30 times that of the Sun. The star lies in the open star cluster NGC 1624 some 20,000 light-years away in the constellation Perseus. The star’s magnetic field is 20,000 times stronger than the Sun’s, and almost 10 times stronger than that detected around any other high-mass star. Additionally, despite their short lives – NGC 1624-2 will live only about five million years – massive stars shape the galaxies in which they live. “Their strong winds, intense radiation fields, and dramatic supernova explosions make them the primary sculptors of the structure, chemistry, and evolution of galaxies.

Physicist: Not just likely, but essentially guaranteed!
Technically, every atom in your body has been swirling all around the galaxy for billions of years (although it’s mostly stayed in the same place for the last 5 billion or so).

A new study has been published that seems very simple yet has some very interesting repercussions: it shows the Sun is the most spherical natural object ever measured.
Measuring the Sun’s diameter is actually rather difficult.
