    Does an object orbiting close to a black hole appear to orbit slower due to time dilation?

    The time dilation applies to the clock in the spaceship that is orbiting, not to a far away observer; he observes everything as expected, an object orbiting a mass, almost Newtonian, The guy in the spaceship, well, he don't see it that way.

    ISS debris avoidance

    Sounds good on face of it, like your other post, but pieces of a kg or more are still very difficult to see, and pinpoint, so you have to put your large areal laser power density (enough to vaporize a hundred gm of metal in a few square inch area in a second or so ->kilowatts) over a large area...

    ISS debris avoidance

    Maybe you can come up with an idea of how to do it, but it is not possible to make a magic ray to zap them. Take a poke at it . . . . Small things you can't even see to zap (sand grains that make for a bad year in space), big things (bolt sized) you can't really see and vaporize in time, let...

    ISS debris avoidance

    They have models from older interplanetary craft, essentially the size distribution of what hits you, and the flux. Measured, known data.

    ISS debris avoidance

    Money, money, money. $100 million to capture a few suitcased sized pieces of which there are thousands, $100 million to capture a dozen or so baseball sized pieces of which there are likely 10,000. The sand grain sized can't even really be seen, and if they were, 100's of trillions of dollars...

    ISS debris avoidance

    The Webb mirrors are especially especially fragile and susceptible to damage from debris. This Webb debris was very small, likely the size of a smoke particle or even smaller. And the damage is mainly miniscule misalignment and warping of the exquisitely engineered and aligned mirror segments...

    Question about big bang theory

    This is very close to the current understanding. Space containing a gravitational field has a negative energy density due to the gravitational field (read Alan Guth's book). Mass with positive energy creates a gravitational field with a negative energy; creation of the negative energy also...

    Could This Be True?

    Not even close. Just a random jumble of high sounding phrases from astrophysics books.

    ISS debris avoidance

    Flecks of paint et al. will not destroy the station, just make pits. The 5+ cm pieces are tracked and avoided. The problem is the 1-4 cm pieces we are blind to but will trash any module(s) they hit, think along the lines of a small, non-explosive artillery shell kind-of-thing. The 5+ guys are...

    Questions about light

    1) ALL light and electromagnetic waves carry energy. Period. Even a single photon. Read Wikipedia for "photon". 2) No. No. No. Hell no. Read Wikipedia "virus" and "photon" and ponder. 3) Absolutely ludicrous assumption, even for SF. A much simpler assumption is that my ass spews out...
