Like.
I can't discern where the ridge is. It's not labelled on the picture. Are they talking about the blob on top of the image? -
Helio reacted to Pogo's post in the thread Collisions could increase chance of 'God of Destruction' asteroid Apophis hitting Earth with Like.
And any strike by another object has a greater chance of causing Apophis to move farther away from Earth as toward it.

Helio reacted to billslugg's post in the thread How can we protect humans on Mars from radiation from solar storms? with Like.
Solar storms are only part of the problem. Galactic cosmic rays are far more powerful and are not stopped by heavy nuclei very well...

Like Questioner said - the center of mass won't move. You can make your contraption rotate, from equivalent counter-rotation within the...

The assembly will not rotate about the motor axis, but around the assembly's center of mass.

Helio replied to the thread Move in Space without mass exchange.Is this somehow different than how gyro motors work for spacecraft, especially space telescopes? Gyroscopes

Helio reacted to Unclear Engineer's post in the thread NASA spacecraft captures 1st photo of its giant solar sail while tumbling in space with Like.
And it is not just a push in one direction. By angling the sail to be off-perpendicular to the direction of the incoming light, the...

Helio replied to the thread NASA spacecraft captures 1st photo of its giant solar sail while tumbling in space.And don't forget light sail propulsion comes with a 2 for 1 special. :) The momentum of the photon pushes the sail when it impacts it...

Helio replied to the thread Belief in alien visits to Earth is spiraling out of control – here's why that's so dangerous.I've been having fun reading a number of books to build my knowledge of just how the BBT got its birth. The astronomy, actually the...

Helio reacted to Unclear Engineer's post in the thread Belief in alien visits to Earth is spiraling out of control – here's why that's so dangerous with Like.
I think the cause and effect are being reversed in the article. I think it is the misbehaviors of our politicians and media moguls...

Helio replied to the thread More on the Big Bang - what was before t = 0?.I keep thinking about what Newton faced. He admitted he had no idea of what constitutes gravity. But he did know its behavior, and...
