"...the expansion of the boundary conditions has its consequences: a new kind of quantum entanglement appears in the theory, mixing past and future, which is not present in conventional particle theory."

I would say it becomes a necessity, and, if not disproved, one hell of a leap in concepts and possibilities.

#PPOD: NASA’s Curiosity Mars rover spotted these finger-like rocks with its Mast Camera, or Mastcam, on May 15, 2022, the mission's 3,474th Martian day, or sol. These rocks likely formed as groundwater trickled through rock in the ancient past, depositing mineral cements over time. When the rock was exposed to the atmosphere many years later, wind eroded the softer material around the cemented portions. Credit: NASA/JPL-Caltech/MSSS

"Baker noted that "there's long been this very human-centric idea of intelligence that only humans are intelligent." That's fallen away within the scientific community as we've studied more about animal behavior. But there's still a bias to privilege human-like behaviors."

The X marks Blue Ghost's landing site on the Moon, seen against the current lunar phase. The spacecraft touched down shortly after sunrise, hence the long shadows.

Blue Ghost is on the Moon! Images are coming in now from what appears to be the first fully successful commercial lunar lander. Just look at that shadow.

Over the next 2 weeks, Firefly's Blue Ghost will drill, study lunar dust, and observe an eclipse of the Sun...by the Earth.

NASA's Lucy mission is named after the famed hominid fossil.

Lucy (the spacecraft) just got its first look at 4-km-wide asteroid Donaldjohanson, named after the anthropologist who co-discovered Lucy's remains.

Lucy is a crazy ambitious mission that will visit a total of 11 asteroids (and maybe more).

Close-up views of Donaldjohanson are coming April 20.

https://lucy.swri.edu/mission/Targets.html #space #science #nasa

The Lucy mission will travel to eight Trojan asteroids and three main belt asteroids. No other space mission is history has been launched to as many different destinations in independent orbits around the Sun! Lucy launched in October 2021. Its trajectory first takes it by the Earth for two gravity assists before it begins its journey out to the Trojan Asteroids. Before its second Earth gravity assist, Lucy will travel through the inner edge of the main asteroid belt and fly by its first asteroid on November 2023. It will fly by the small asteroid (152830) Dinkinesh and its satellite. Later, on its way out to the Trojan asteroids, Lucy will travel through the main belt again and fly by anoter main belt asteroid on April 2025. It will fly by (52246) Donaldjohanson, an asteroid that the Lucy team named after one of the co-discoverers of the Lucy fossil.

Ever since a PhD student introduced me to the idea, stolonization has been haunting my waking hours. Now it can haunt yours too: some annelid worms develop a gamete-filled structure (stolon), which detaches and swims to find a mate. Some stolons have eyes, antennae, and nervous system 🤯

The image shows female (left) and male (right) stolons which detach from their seafloor-dwelling 'parent' organism and swim to seek each other out.

The underlying region of complex cognitive functions in birds and mammals--the pallium--arises from different genes, different embryonal tissue, and develops at different rates in these two taxonomic groups. Similarity of functionality has arisen through convergent evolution.

I've been seeing hate on NASA lately, being bought into by leftists even, and I just want to point out something very important:

Musk has hated NASA for a *long* time. There is a reason it is being attacked, and a reason public opinion is being swayed against NASA: It *keeps SpaceX in line* more than anything else.

NASA is being seen as "competition" to SpaceX, as the obstacle in his way. It has been like this for quite some time, and now, with DOGE and other things, he can do something about it.

I would like to point out a few things:

1. SPACEX IS NOT CHEAPER
They boast they can "do what NASA does for 10% the cost!" Sure, it's easy when you did none of the R&D.
SpaceX saved on:
Landing tech: DC-X project in 1991-1996
Tank structure: Shuttle SLWT tank, 1998-2011
Merlin Engines: direct descendant of the Fastrac Engine, 1997-2001.

Those three things alone saved SpaceX over 90% of the R&D costs. It's easy to "appear" cheap when you're using off the shelf tech someone else (NASA!) developed.

2. NASA IS GREAT FOR THE ECONOMY!
For every $1 spent on NASA, $8 is put into economy. Its stupid to not invest in that kind of ROI! 800%! At times, its ROI Has been 1600%!

Simply put, if you defund NASA, the economy would shrink so much you would actually have to RAISE taxes to make up for the lost revenue, and without its existence we would be 30 years behind in technology and the quality of life for everyone would be much lower. Science and research is GOOD for society, it's the fuel for all progress.

3. WHAT HAS NASA DONE FOR ME?! (Surely you just mean NASA is good for tech & science folk....)

Nope! Good for all!
Ever have an MRI or CAT Scan? They wouldn't exist without the Apollo program! The software that made them possible was originally written to analyze lunar photography.

Low power digital x-Rays was planetary body research.

Heart pumps are modeled after space shuttle turbopumps.

The software that designed your car was originally written to design spacecraft!

Who do you think pioneered all the early research into alternative power like solar panels, hydrogen fuel cells, and durable batteries? NASA!

NASA developed tech and satellites is also what improves agricultural yields while reducing the needs for water, fertilizer, and pesticides.

Do you really think Musk gives two shits? No. He wants the money, he wants to let SpaceX run amok without any oversight for safety, without any "competition".

All fights are important, but do realise that this one is a huge thorn in his side, and one that is keeping a huge problem from ballooning and swallowing us all whole.

Do not be fooled or swayed by lies, of tactics meant to divide, of things being done to make you be angry at NASA. If he can make you hate NASA, he won.

Expect far more space junk to fall, the night sky to be ruined by satellites, and the loss of all things good that proper research and design does for humanity and gives back to the world. Not to mention: enjoy seeing the horrible things he can accomplish fully unchecked.

ETA: Now that you know, call / fax / email your senators and reps, and whatever else too! Boosting gets people thinking, but thinking is not action!

The A1 is a vertical firing single position stand, meaning it holds one rocket engine at a time in an upright position with thrust directed downward. You can see the RS-25 engine in the stand, there is a truck and a large van for some scale. The NASA logo (meatball) is proudly displayed on the upper right of the stand.

Phobos and its smaller neighbouring moon, Deimos – both discovered in 1877 – are two of the most perplexing worlds in the solar system. “They’re the only objects at this stage, in the solar system, for which we have pretty much no idea what they are,” says Pascal Lee at the SETI Institute in California. “We know what other moons are. We know asteroids and comets. Phobos and Deimos? No idea.”
