billslugg replied to the thread Boeing plans to lay off hundreds of employees working on NASA's SLS moon rocket: reports.It's not a "space versus airplane" problem, it is a management problem. The engineers got taken over by the accountants. (See: "737 MAX")

billslugg replied to the thread 3D-printed 'hydrogels' could be future space radiation shields for astronaut trips to Mars.Shielding of very high energy massive ions requires many tiny collisions to remove the energy. We don't want dangerous secondary...

Thank you; now I understand how and why this exoplanet rotates. And as you say, this doesn't do anything to explain the unbelievably... -
billslugg replied to the thread What the asteroid with a 1-in-48 chance of hitting Earth in 2032 looks like (images).2028 is the next close pass to Earth, a good time to hit it to change its orbit. One such plan requires only ten days from launch to impact.

billslugg reacted to YetAnotherBob's post in the thread Scientists accidentally discover Earth's inner core is less solid than expected with Like.
It's a semi-solid, make that like molasses. It's still subject to tides. those have a slowing action until the planet is tide locked. So...

billslugg replied to the thread Astronomers realize mysterious TV signal in their data bounced off an airplane.We need to go to the far side of the Moon to site large arrays of low frequency antennae. Putting them on Earth is a losing proposition.

billslugg reacted to Max Wrent's post in the thread Astronomers realize mysterious TV signal in their data bounced off an airplane with Like.
back in the analog TV days using antennas, we called that multipath. Multipath signals from aircraft would cause image ghosting.

billslugg replied to the thread Scientists accidentally discover Earth's inner core is less solid than expected.The core has a certain angular momentum. How can that change? Maybe some fluid is pushing sideways on one of its surface bumps.

billslugg replied to the thread Explanation for cosmological red shift of light.When a charged particle moves sideways it creates an EM wave that moves outward perpendicular to the direction of motion. A simple...
