    China's space plane apparently deployed 6 'mysterious wingmen' in orbit

    It will be interesting to see what happens when OBJECT A meets OBJECTS D and E. Could OBJECT A be a predator and OBJECTS D and E targets?

    Question Perfect Gravity Lens?

    While we are making our super lens, let’ save some of that negative gravity for a no-fuel-required spacecraft. We put a glob of negative gravity on the tail and some positive gravity on the nose, and we can travel throughout the universe with zero fuel consumption.

    Question Perfect Gravity Lens?

    I think the light from individual stars (or other objects) would get "mixed-up" in the gutter and the output at the focus would just be a bunch of light. That would make a poor magnification device, but it may have other uses.

    Sun blasts out highest-energy radiation ever recorded, raising questions for solar physics

    The sun is not creating global warming. Man-made changes are causing the earth to retain more of the suns energy, thus warming the planet.

    Why the need to prove a cosmological constant?

    I believe it was Heraclitus who said “The only constant is constant change.” The other quote I like, but don't know the source, is "Constant change is here to stay."

    Top 10 best (or worst) terms in astronomy and physics

    I have always thought "black hole" was an unfortunate choice of names. A hole is usually considered empty or sparsely populated, yet the center of a black hole is the most dense object we know of. I nominate "light sucker" as the new name.
