S13Ni, (edited ) to tech in NASA propulsion technology brings 'flying cars' closer to reality

Flying cars is a fucking stupid idea.

-constant fear of some drunk driver flying 300kmph to your house

-only useful for medium length journey

-has to be heavily controlled for safety, meaning you can only fly specific routes

-airspace of anything important is no fly zone, like airports, government buildings, ports, basically every city

-needs fossile fuel to fly, more than a normal ICE car

-needs designated landing area

-needs city planning to be centered around them

-unlimited potential for terrorists

-drivers would need specific license and training

Whoever is unironically shipping flying cars is a fucking moron and you can’t prove me otherwise, no matter if it technically works or not.

SlopppyEngineer,

A flying car in bad weather or at night is going to be a challenge. Icing is very dangerous. Drivers now can barely clean their windows before departing.

Flying cars are big and need several parking spots to squeeze in. It’ll be a challenge to find enough room nearby or to make it affordable. I doubt suburbs will turn into fly-in community quickly.

Flying car = helicopter. All you need to say.

Flying cars are the modern equivalent of flying horses

tiredofsametab,

Even more simple than most of those: people are shit at driving in two dimensions and adding a third is just idiotic.

MJBrune,

I bet you that because flying cars are likely going to be a rich only thing that cities will quickly create new infrastructure to help flying cars become marketable.

rtxn, to earthscience in The ozone hole above Antarctica has grown to three times the size of Brazil

The solution is obvious. We must increase the size of Brazil.

Tolookah,

Increase, or decrease?

rtxn,

The issue is the ratio of the ozone hole in relation to Brazil, increasing the size of Brazil (the denominator) decreases the ratio.

Tolookah,

But making Brazil smaller makes the hole smaller, right?

HWK_290, to startrek in Space.com poses the debate-provoking question whether SNW S2 overdid the gimmicks

What turns me off about SNW is that The Orville is a better return to form to “classic Trek” than actual Star Trek. The episodes revolving around Topa’s gender and identity is some of the best scifi commentary on modern society out there right now.

I think it’s good that CBS never gave MacFarlane his own ST show, lest he be beholden to all the history of the franchise (the same thing that is, in part, weighing down SNW). Who knew that khan was Kirk’s father’s brother’s nephew’s cousin’s former roommate?!

Lauchs,

Wait, what does that make Khan and Kirk?

HWK_290,

… Absolutely no relation

@HWK_290

Be careful about praising The Orville the way you are to people who remember TNG very fondly. It apes TNG very closely but also has more than its fair share of Mcfarlane’s Family Guy humor which isn’t for everyone and definitely doesn’t jibe with Trek.

The episode where we first meet the Krill has Lt. Malloy laughing maniacally and constantly at the fact that the Krill’s god is named Avis. This just isn’t that funny and breaks immersion.

McFarlane himself admits this episode was very juvenile and the show gets quite a bit better once he decides to stop going after Family Guy style jokes. Many people won’t watch enough episodes to see the show is worth a chance.

T156,

I’d argue that the Star Trek history weighs it down more than that. Even without the historical references, much of the shows seem to be held back by the trying to live up to it, or having to stick to the same formula. Enterprise and Voyager famously suffered from considerable network meddling to try and recapture TNG, for example.

It could work, but it also means that much of any social commentary that does show up is a bit hampered, since the network wants a safe, conservative star Trek show (and the fans might be partly to blame, because they also want more of the same too, so much of the time).

A modern TOS that pushed boundaries as the original could never be made under the same brand. It’s far too controversial for the network to accept, with all of its progressive and social commentary elements intact.


Not that it’s a fault of Star Trek’s specifically, just an issue with how big it has become. If the Orville became a similarly established brand, instead of Star Trek, it would almost certainly have had the same issues.

Lucidlethargy,

Agreed, but knowing scientists that’ll probably take at least 596 years to achieve.

Tbh no other language but English has the same problem. In some languages it is simply ‘Uran’, and it does not mean anything but Uran.

ShaunaTheDead, to climate in These scientists want to put a massive 'sunshade' in orbit to help fight climate change

The big problem with a sunshade is that it would be an engineering project on a scale that we have never seen, and we're not really entirely sure it would work. It would cost at least $10 trillion USD and require launching nearly 200 billion small vessels and moving them into the L1 Lagrange point between us and the Sun. Each vessel would have a shade that covers 2500 m^2 with a total mass of ships and shades being 34 billion metric tonnes.

A sunshade just isn't feasible and all of those rocket launches to get it into position would just exacerbate the already pretty awful situation here on Earth, not to mention mining all of that material and building the rockets causing greenhouse gas emissions, and is there even 34 billion metric tonnes of material on Earth with which to make effective sunshades out of?

It would be a MASSIVE, MAAAASSIIIIIVE undertaking the scale of which Humanity has never seen to get it done, and we're not even sure if it would work. We're much better off focusing on solutions here on Earth, I think.

For those curious, here's a scientific paper looking into the subject that I used for reference on the numbers I used: https://www.sciencedirect.com/science/article/pii/S0094576521001995

set_secret,

immediately transitioning to zero emission and planting a shit tonne of trees would probs be cheaper.

silence7,

Above and beyond what you’ve said: we would need to maintain that sunshade for hundreds of thousands of years.

Civilizations don’t tend to last that long. The odds of our being able to actually maintain technical infrastructure like that for the required amount of time are low.

Orbituary, to science in Cosmic nuclear fission seen for 1st time in 'incredibly profound' discovery
@Orbituary@lemmy.world avatar

This ultimate neutron star merger releases a wealth of free neutrons, which are particles normally bound up with protons in atomic nuclei. This can allow other atomic nuclei in these environments to quickly grab these free neutrons — a process called rapid neutron capture or the “r-process.” This allows the atomic nuclei to grow heavier, creating superheavy elements that are unstable. These superheavy elements can then undergo fission to split down into lighter, stable elements like gold.

In 2020, Mumpower predicted how the “fission fragments” of r-process-created nuclei would be distributed. Following this, Mumpower’s collaborator and TRIUMF scientist Nicole Vassh calculated how the r-process would lead to the co-production of light precision metals such as ruthenium, rhodium, palladium and silver — as well as rare earth nuclei, like europium, gadolinium, dysprosium and holmium.

@overzeetop@lemmy.world avatar

In a way it’s baffling that we have so many “heavy” elements on Earth, given the way they are formed and how (almost) impossibly rare they should be.

AngryCommieKender,

Well there’s a whole lot more dust out there, that should have similar composition to the solar system. So much so, that every “empty” cubic light year of space contains about 28.8 solar masses. That’s a whole lot of everything just floating around waiting for gravity to do its thing and clump them into things.

Pons_Aelius, (edited )

One reason is that the dust cloud that formed our solar system have already gone through several rounds of of star formation and supernova to seed it with the heavy elements.

The second reason is that when the sun reached fusion and started pumping out the solar wind it pushed a lot of the lighter elements to further out in the solar system. That is why the rocky planets are the inner four and the gas giants are the outer four.

Earth has a much higher proportion of heaviest elements than the proto-cloud (which was metal rich in the first place) because of the second reason.

JimmyBigSausage, to space in James Webb telescope finds an 'extreme' glow coming from 90% of the universe's earliest galaxies

I wish I understood this. Can someone explain it like I was five?

Dagrothus,

Aliens

JimmyBigSausage,

Thanks. I get it now.

ubermeisters,
  • A big telescope called James Webb that can see very far in space and time. It can see how the first stars and galaxies were born after the Big Bang, which was a huge explosion that created everything.
  • James Webb found out that most of the first galaxies had a lot of gas around them that was very bright. The gas was lit up by the light from the stars inside the galaxies. The gas also helped make more stars by cooling down and clumping together.
  • This discovery is important because it helps us understand how the first galaxies grew and how they made the different elements that we have today. The article also says that this discovery is surprising because the first galaxies were much brighter and bigger than we expected.

chuckleslord,

Yes, it usually doesn’t pose a danger anymore. But it’s a natural process. It took time to damage it, it takes time for it to heal. It will close again in 2040 (back to 1980 levels of ozone)

Probably going to be something like:
Yes, there is shit we haven’t been able to fully identify, 'cause we often get terrible data and video has a lot of problems with perspective and lens artifacts. So ya, it’s Unknown. If you’re jumping from there to aliens, spirits, etc. then you are an idiot. Evidence works both ways, we can’t prove it’s any specific phenomena, but your evidence for even worse.
