Уважаемые коллеги!

На заседании Ученого совета ИТФ в пятницу 13.03 будет заслушан 1 доклад:
11:30 С.Н. Вергелес
Дискретная $Z_4$ симметрия в решёточной теории гравитации: симметричная и несимметричная фазы.

Рассматривается решёточная теория гравитации при сверхвысоких температурах. Определяется глобальное $Z_4$-преобразование фермионных дираковских и бозонных полей (тетрада и элементы голономии), из которых строится решёточное действие. Это $Z_4$-преобразование является "корнем" из $Z_2$- или $PT$-преобразования, ранее предложенного автором. При самых высоких температурах рассматриваемое действие инвариантно относительно преобразования $Z_4$, и эта симметрия не нарушена. При понижении температуры $Z_4$-симметрия нарушается до $Z_2$-симметрии, причём параметром порядка является $Z_2$-симметричный вклад в действие, трансформирующийся в длинноволновом пределе в действие Гильберта-Эйнштейна. $Z_4$ преобразование смешивает частицы и античастицы, так что в $Z_4$-симметричной фазе исчезает различие между частицами и античастицами (на языке Дираковских полей).

Taking you out of this world, every day

The Launchpad

International Space Station may keep flying until 2032

(NASA)

Happy Monday, Space Fans! It's a new week in space (and also on Earth) and today's top story actually includes both: U.S. lawmakers in Congress are pushing to extend the life of the International Space Station beyond NASA's 2030 deadline to deorbit the $100 billion space lab. Find out why in the story here.

And that's not all! (It never is, right?) We've got a stunning meteorite crash through a house on Earth, the risk of privatizing Plan B for humanity and are you excited about 'Project Hail Mary'? Because we're excited about 'Project Hail Mary.' See it all below.

Space Quiz! Which workhorse rocket does SpaceX use for Starlink launches?

Find the answer HERE!

Space deal of the day

Lego Marvel Iron Spider-Man Bust has never been cheaper

(Lego)

Remember that time Spider-Man went to space in Avengers: Endgame? We sure do, and this LEGO deal will let you rebuild that version of the Iron Spider-Man for 20% off. Here's where you can find it online.

Fireball over Europe sends meteorite through roof

(Fireball inset: Marcel W via AMS, background added in Canva Pro)

We've seen some spectacular meteors in the sky, but a meteorite crashing through the roof of a house? That's pretty rare. And it's exactly what happened to these folks in Germany. See what happened here.

Spaceflight

Should private companies lead our Plan B for space?

CAPE CANAVERAL, FLORIDA - SEPTEMBER 09: SpaceX's Polaris Dawn Falcon 9 rocket sits on Launch Complex 39A of NASA's Kennedy Space Center as it is prepared for another attempt to liftoff on September 9, 2024 in Cape Canaveral, Florida. The Polaris Dawn mission is a private spaceflight backed by Jared Isaacman, the billionaire founder of payments platform company Shift4. During the mission, the astronauts will attempt the first spacewalk by a private company. The launch has been re-scheduled from Tuesday, August 27, to Tuesday, September 10th, at 3:38 am and has a four-hour window. (Photo by Joe Raedle/Getty Images)

Some private companies like SpaceX say humanity needs to settle other planets as a Plan B for survival. But should that project be led by a commmercial company? Some scientists are wondering. So, what do YOU think?

Search for Life

Is space weather hiding calls from aliens?

(SETI Institute)

The year is 2026, so where are all the aliens? Well, a new study from SETI suggests that space weather around distant stars may be interfering with E.T. calls. Here's what they found.

Hours after setting clocks forward for Daylight Savings Time, SpaceX went forward with a launch of Starlink satellites on March 8. Chalk up another 25 Starlink satellites for the company's space internet constellation.

Entertainment

'Project Hail Mary''s final teaser is 'Amaze! Amaze! Amaze!'

(Amazon MGM Studios)

Amazon MGM Studios recently released the new final teaser trailer for their interstellar buddy film, with fresh footage that has legions of book fans going joyously berserk over a phrase recited by Rocky. What do you think of his design?

On this day in 1961: Soviets launch dummy, dog & guinea pig

(Smithsonian/Wikipedia)

On March 9, 1961, the Soviet Union launched Sputnik 9. This mission was a test flight of the Vostok spacecraft, which would later carry the first cosmonauts into space. Can you guess the mannequin's name? Find it out in our full video here!

Editor's Note

Have a great week!

And that's a wrap on our first space newsletter of the week. Thanks for reading to the end and keep an eye out for a series of SpaceX and Firefly Aerospace launches week. We'll have that coverage on the main Space.com website. Keep looking up! Tariq Malik Editor-in-Chief, Space.com
