  • how a black hole is formed 8.7 years ago

    @picy You're on the right track. Particularly about stellar masses. Core collapse is an amazing process. Lots of fun things go on to make the magic happen. Astrophysics is one of my favorite fields (right up there with aviation and aeronautics).

  • how a black hole is formed 8.7 years ago

    It's only the core that collapses, not the entire star. The outward pressure of energy being released by fusion in a star's core resists the colossal inward pressure of the gravity generated by the star's immense mass. As the core runs out of fusible hydrogen, it goes through its helium, carbon, neon, oxygen, and silicon (silicon lasting only days before exhaustion. Once the core is left with only the nickel and iron products, the fun begins. You see, iron cannot produce energy through fusion, so the stellar engine breaks down. No more energy is being radiated outward, so gravity begins to take over. Then, it's up to the Pauli exclusion principle, the degeneracy pressure of electrons. Once the hard Chandrasekhar limit is passed by the core under this pressure, exclusion breaks down, and all the matter is pushed inward at a quarter the speed of light! Protons and electrons are merged into neutrinos which escape the core, and all that is left behind is a degenerate mass of quantum compacted neutrons. This is such an energetic event, it creates a rebounded shock wave so powerful, it shreds apart all the outer layers of the star, blasting matter outward to form a stellar nebula. Now a collapse into a black hole is something entirely weirdly different. Thanks to quantum behavior of the material the neutron star is made of, the size of a neutron star remains constant as its mass is changed. This means if a neutron star is massive enough, its Schwarzschild radius will rest outside its limb, creating an event horizon, and causing a black hole to form. This also means that if a neutron star's Schwarzschild radius is still within its limb, it can be coaxed outward by adding mass to it until the event horizon forms, since a neutron star's volume will remain constant. Physics as we know it breaks down behind the horizon, so we have no way of knowing for exactly what occurs beneath it. All we know is that the gravity is so strong, it has command over light, and stops time itself. Scary stuff.

  • No thrust intercepter missiles 8.7 years ago

    Did you clip the water at all? Even if your plane recovers from a quick dive into the water, all your missiles will be disabled as a result of being submerged. They'll fall off the pylons and just drop without firing.

  • Kinematicist 8.7 years ago

    @JoddyFubuki788 hehe yeah. You really crank those engines for all they're worth. I was just trying to be more modest lol.

  • HTM-D1 Dogfight challenge 8.7 years ago

    @Thehtmguy When you upvoted my plane, I looked at your posts and found something that didn't get much attention, so I gave it some.

  • Leaked SimplePlanes 2 Image 8.7 years ago

    That's true. Aerodynamic heating is serious business.

  • Kinematicist 8.7 years ago

    @MAHADI Thanks a lot!

  • Kinematicist 8.7 years ago

    @Kentheman Thanks.

    @Liquidfox Thanks.

  • Prowler Dropper 8.7 years ago

    @Kerbango Interesting. @ me when you finish it.

  • Prowler Dropper 8.7 years ago

    @Kerbango I never meant for mine to be so popular. Had I known, I would have made the delivery plane less ugly. Now 2581 people have it.
    Thanks btw!

  • Slipsail 8.7 years ago

    @Treadmill103 Thanks.

  • Lockheed P-38L Lightning "Sky Lightning" OUTDATED 8.7 years ago

    @Lavochkin Thanks!

  • Lockheed P-38 Lightning Gold 8.7 years ago

    Looks like your older P-38 slipped under the radar when I was cataloguing them.
    Will add.

  • How do you get your plane to turn so smooth 8.7 years ago

    What you are experiencing is an effect caused by a control surface being moved past its best lift-generating angle for a particular airspeed and angle of attack, causing the torque on the plane to drop off slightly after passing its peak. Maintaining a more hands-on control and avoiding moving the stick to the stops can help avoid this. Some planes happen to be perfectly engineered so that the stop is also the most efficient angle of the tailplane.

  • Lockeed P-38L Lightning 8.7 years ago

    HOWEVER, despite the aesthetic detail being the best I've probably ever seen, there are a few small structural inaccuracies. Most noticeable is the lack of a dihedral on the wings, which also makes the booms sit lower than they are supposed to. The size is a little off as well. It's a few feet larger than the genuine article. Also the propellers both spin in the same direction, something only P-38s exported to the British did. Since this aircraft has American markings, is should be assumed both propellers spin up-and-out. Lastly, the landing gear give this Lightning a totally level ground angle. The P-38 sat with a slight nose-up angle, meaning the nose wheel should extend slightly lower than the main wheels.


    However, despite these few nitpickings, (and many small others I could drone on about for hours), this lightning is among the best I've seen. 9/10 overall. Great job!

  • Lockeed P-38L Lightning 8.7 years ago

    @ChiChiWerx Oh yes! This is quite nice indeed. A top-scorer in my opinion!

  • Every P-38 Lightning Ever 8.7 years ago

    @Deloreandude I'm sure there's still some I missed. Apart from the new ones I continuously catalogue, there's an occasional unseen old one that will come to my attention.

  • P-38 2 Lightning 8.7 years ago

    @Deloreandude You know me too well!

  • Lockheed P-38L Lightning "Sky Lightning" OUTDATED 8.7 years ago

    @Mumpsy Thank you much!

  • Forklift Truck! 8.7 years ago

    I drive forklifts in real life. I crash them much less than I crashed this one.

  • P-38 2 Lightning 8.7 years ago

    Hmm. Yes. I like this.

  • C-17A Globemaster III (Boeing) 8.7 years ago

    Phenomenal!

  • The Oscillator (glitch plane) 8.7 years ago

    Turns pilots into jelly, but worth it for the cool factor.

  • iN-306 Kodiak 8.7 years ago

    I always feel uneasy about the doors being behind the props, but then I remember the C-145A is a thing.

  • Every P-38 Lightning Ever 8.7 years ago

    @Noval5 Yeah, It's quite comprehensive.

  • Scout Rugged 8.7 years ago

    Simple is good.

  • MYTHBUSTERS can a cockpit get 10 upvotes?! 8.7 years ago

    @SHCow Nice. I don't often do detailed cockpits. I thought of doing one for my P-38, but decided not to.

  • MYTHBUSTERS can a cockpit get 10 upvotes?! 8.7 years ago

    @SHCow We'll see when you release it then. If it shows up, I'll try and troubleshoot it like always.

  • MYTHBUSTERS can a cockpit get 10 upvotes?! 8.7 years ago

    @SHCow I'm always fashionably late.

  • Replica or Fictional? 8.7 years ago

    Go fictional. Total creative freedom is much more fun than constantly checking blueprints.

  • MYTHBUSTERS can a cockpit get 10 upvotes?! 8.7 years ago

    Here I am. Mr. #10.

  • Gettup-and-Go 8.8 years ago

    @Treadmill103 Thank you.

  • Gettup-and-Go 8.8 years ago

    @SHCow Yeah. The old prop behaves pretty much just like a low-powered jet. Tweak the numbers in XML a little bit, and the thing delivers some insane thrust. The engine here is basically being decuple-redlined.

  • QC-7.5 8.8 years ago

    @Feanor That'd give the flightline firefighters something to do at least.

  • Widow-Maker 8.8 years ago

    @Unreliablewaffle365 The aptly-named widow-maker makes another widow.

  • WORST REPLICA EVER?!? (again) 8.8 years ago

    Looking good! Did you do any more work on the cockpit interior?

  • Can you explain what made my build fly about 3000+ with out engine 8.8 years ago

    The way this game simulates flutter occasionally causes a glitch where the wings oscillate at an incredible frequency.
    If you've ever seen one of the good ornithopters on the site, you'll know that flapping wings can indeed generate thrust without the need for engines.
    These wings flapped SO FAST, the aircraft got propelled to hypersonic velocities in an instant.
    Also, just for fun, I did a little math, and our pilot there probably pulled around to 100 g for 2 seconds. He'd be dead before the plane even crashed.

  • wing-less plane 8.8 years ago

    @marcox43 That is an expression of disbelief. He is surprised that this plane flies.
    And it's true. I too was quite impressed by the fact I could fly this without crashing.

  • QC-7.5 8.8 years ago

    Seven engines lol. Maintenance crews would hate this plane.
