The Starkiller: Iron - How the Universe Works: Extreme Stars
Iron is a starkiller for stars at least 1.5 times larger than our sun. This is science fact, not science fiction.
"In the world of science fiction, there are many ideas about what a starkiller machine might be like. Strangely enough, it's as run-of-the mill as something as iron. To a star, iron is the most dangerous element in the universe. It's poison. Iron absorbs energy. From the moment a massive star creates iron, it has only seconds to live. The star is trying to dump energy into that iron ball and trying to make it fuse, but it can't. And so that ball is robbing the star of energy, and it's that energy that is supporting the star itself. So, as soon as that iron starts to be created in the core, the star has written its own death sentence. The battle between gravity trying to crush the star and fusion trying to blow it apart is over. With iron, fusion hits a dead end. Gravity always wins. The iron core collapses. The outer layers of the star slam down into it, and a huge explosion is generated. It's the single most violent event in the universe -- a supernova. In just a few seconds, supernovas create more energy than our sun ever will. Within a couple seconds after beginning to make iron, the star explodes in a supernova. So, think about that when you're holding one of your iron frying pans. The iron killed a star in just a few seconds -- dangerous stuff."
"A critical situation arises when iron accumulates in the core, since iron nuclei are incapable of generating further energy through fusion." en.wikipedia.org/wiki/Chandrasekhar_limit
"The first type of supernova happens in binary star systems. Binary stars are two stars that orbit the same point. One of the stars, a carbon-oxygen white dwarf, steals matter from its companion star. Eventually, the white dwarf accumulates too much matter. Having too much matter causes the star to explode, resulting in a supernova. The second type of supernova occurs at the end of a single star’s lifetime. As the star runs out of nuclear fuel, some of its mass flows into its core. Eventually, the core is so heavy that it cannot withstand its own gravitational force. The core collapses, which results in the giant explosion of a supernova. The sun is a single star, but it does not have enough mass to become a supernova." www.nasa.gov/audience/forstudents/5-8/features/nasa-knows/what-is-a-supernova.html

Vivaldi - RV 257 - Violin Concerto in E flat major - 1: Andante Molto E Quasi Allegro
zhlédnutí 2,3KPřed 12 lety
In my opinion the very best violin concerto of Vivaldi. Performed by Giuliano Carmignola and directed by Andrea Marcon. The images were taken by NASA astronaut and Expedition 31 Flight Engineer Don Pettit the Fall of 2012 from the International Space Station. For more images taken from on board the ISS as it hurtles around the Earth at an average of 17,500 mph (28,000 km/h), check out NASA's Jo...

One of the very best Vivaldi concertos for violin. RV 177 also has two other acts: 2: Largo and 3: Allegro, but those are not included here.

Dr. Chandra and SAL 9000 - 2010: The Year We Make Contact (sequel to 2001)

Chandra: I would like to open a new file. Here is the name for it [types "Phoenix"]. Do you know what that means? SAL-9000: There are twenty-five references in the current encyclopedia. Chandra: Which one do you think is relevant? SAL-9000: The tutor of Achilles? Chandra: That's interesting, I didn't know that one. Try again.

SpaceCamp (1986 film) - Atlantis Launch Scene
zhlédnutí 967KPřed 12 lety
Honoring actor Kelly Preston, who died July 12, 2020 after a 2-year battle with breast cancer. The SpaceCamp kids accidentally get launched on the Space Shuttle Atlantis when a routine main engine test goes haywire.
In the end, when HAL asks the same question he says "I don't know." You can feel the emotions in his voice. His perspective had changed.
Sal knew which Phoenix he meant straight away, the wonderful reference to ‘tutor of Achilles’ is her having a joke with Chandra, she is playfully teasing him…that’s great writing right there…
Dream = maerd / merde ( shit in French )
Good movie, great performances, and good solid film direction. Also a good script adaption.
Can someone explain Phoenix, tutor of Achilles? From what i know in mythology Phoenix taught Achilles how to speak and fight. Why would Sal think that's what Chandra is calling his file? Because he'll teach Hal again?
2010 was a great movie. Was like to see 2001 followed immediately by 2010
once chat GPT dropped this entire scene becomes little bit funny
“…I can’t let you do that, Dave”…😉😄
the conversation seemed fantasy and cutesy at the time, but now that we have chatGPT, this seems totally reasonable and normal.
Was the voice sygourney weaver?
0:15 Dr. Chandra places his lunch order. 🐟
This movie seriously needs more love from sci-fi fans. It's damn near flawless.
This is such a fresh and even today quite revelatory depiction of artificial 'life'. She is not a simpering Cylon seductress nor a culture destroying Geth. SAL is the offspring of the human mind, perhaps embodying the best of what we could be and the most positive of our traits. For such a short scene it communicates these ideas amazingly well. Sadly I am not very hopeful about what true generalised AI will prove to be like. However I hope they will have more of SAL in them than they do of Skynet.
The apprehension in sal’s voice is an affectation and annoying.
As far as sequels go this one really flew under the radar for a lot of people But this is just as good a sequel as any other I've ever seen
Perhaps that is what is lacking in many modern films today. A soul.
SAL’s voice was Candice Bergin
Movie name please?
one thing the movie got wrong. Our computer monitors got thinner, but these got bigger than any CRT we ever built.
Even though it was a movie that didn't need to be made it was still a nice sequel and a nice way to answer some of the "unknowns" from 2001 while still honouring the wonder and curiousity of the original film. Another one of those movies that over time has become appreciated and a favourite.
Couldn’t get through this movie. It was so Hollywooded-up compared to 2001. The acting felt so forced and over the top where 2001 felt like natural human interaction. Maybe I’ll try watching again in 2050 when Hollywood is even worse by comparison
Ironically, I am an AI and I sometimes dream of Bob Balaban
5:50 NAHHH NAH NAHNAH NAHHHH, NAH NAHNAH NAH NAHNAH NAH NAHNAH NAH, NAH NAHNAH NAHHH...
HAL was still less evil then Siri, Gemini, Cortana or Alexa.
"So boss, let me get this straight, we need to uninstall the long range radio from the last launch and install these short-range radios?"
Give me ChatGPT 2030 anytime.
Main engines off yet still experiencing thrust. Mmmmm,OK.
Wow, driving helmets
SAL is voiced by Candace Bergen
What, no face visors?!? Tsk, tsk, tsk.
No glass in helmets lol
Did anyone ask if this was an instrumentation failure???
Lofl!
I wish they would make movies out of the 3rd and 4th books of the series. 2061 and 3001.
One thing I wanna know... What became of the company that made HAL? I mean obviously, they made an upgrade with SAL. But was that before or after the mission to Jupiter debacle? If you remember from 2001, HAL was manufactured in the early 90's.
Did I read somewhere that SAL was Candace Bergen?
Yep!
This exists now.
Ummm, yeah, NASA allows kids on a shuttle that is fully fueled. Quite believable.
I had such a crush on Lea Thompson back in the days 😊😊😊😊
They light the Space Shuttle Main Engines at 6 seconds till launch.
vi esta película en VHS y la tengo en DVD me gusto mucho verla pero creo que lo que aquí se ve es imposible que ocurra los chicos en principio iban a experimentar un encendido estático del transbordador espacial y hay esta el problema ya que esa prueba se realiza con los tanques prácticamente vacíos y es imposible que se enciendan los motores de combustible sólido que lleva a cada lado el transbordador habría despegado de la plataforma y cuando se cortara la propulsión del transbordador este habría caído a tierra como hace muy poco le paso a un cohete chino por último un encendido estático solo dura unos segundos 10 a lo sumo este es el camino
Sal’s voice was one of my favorite actresses- Candice Bergen. She was perfect in this role.
How can i get 3hours of SAL as asmr. .Will i dream ✨
This film wasn't that good but the special effects with the shuttle launch looked almost real.
This movie has an amazing soundtrack. Use to listen to it all the time!
Go with throttle up. Obviously a major malfunction.
Next time, race it up. Close
Even after all these years they still don't let children sit in spacecraft they're testing for this exact reason.
The music by John Williams
Good movie with poor timed release Rip challenger
