    btr liked post by Physicist On thread : "Regaining momentum takes three times as much energy as sustaining momentum" - explanation please!
    Welcome to the forum. Unless there are forces at work momentum is constant. However since he's talking about momentum being sustained it means that there are no forces at work here. Since there...

    If a star explodes then the energy of the exploding start is conserved. You thought that was a problem because when asked you responded by saying What must still be around? The energy of the...

    pikpobedy liked post by Physicist On thread : How does matter bend space time?
    That makes no sense at all. Either something is true or it's false. It can't be both. I most certainly can dismiss it. Especially since I'm right and he's wrong. This most certainly not a...

    No. The Planck mass is nature’s maximum allowed mass for point-masses (quanta). If two quanta of the Planck mass or greater met, they could spontaneously form a black hole

    If you want to transfer try Princeton or MIT. Although they are notoriously hard to get into. As for textbooks I'd have to say Astrophysics in a Nutshell. I just bought it and love it. You can...

    Dear amitSingh95, Welcome to the forum! :) I'm sorry for not getting to this earlier. I thought I posted a response but it appears that when I posted my response it never got through. Now I...

    I can't help you until you answer the questions I asked you. You're making mistakes and I can't help you respond to my questions. I showed you mistakes that you need to correct before we move on....

    Not a bad idea. Let me know what you run into for reading material. I'd like to take a look too.

    Hi Mayflow, Did you ever read those chapters on the philosophy of science that I sent to you? If so then what did you think about them?

    That's trivial. It's a well-known fact in Newtonian dynamics that force is an invariant quantity between inertial frames. If one frame is moving relative to another in the x direction then the...
