Answer	—	A: Could Vocal Mimicry be a Viable Tactic for a Predator? As it happens, I know of a predator combining vocal mimicry with other forms of mimicry. This is so horrendously effective that it can infiltrate the colonies of its victims and remain undetected while killing and eating their children for nearly a year! During its lifecycle, it will consume on avera... (more)	—	about 4 years ago
Answer	—	A: How soon does the Earth's surface re-solidify after the red-giant Sun is replaced with a different star? Okay... it's not a precise answer, but here goes. I'll start by discussing my research into the Moon's solidification, since it's relevant, especially as the Moon took longer to solidify than the Earth originally. (I edited all this into the question as supporting information.) Then I'll go from ther... (more)	—	about 4 years ago
Answer	—	A: The Earth and Moon resolidify under a bluer star, their outer layers evaporated and burned away. What do they look like now? This answer contains two answers, rolled into one. First the Moon, then the Earth. The Moon: The Moon - in short: Lots of green and black crystals, but because of the sun they look a bit bluer than they would on Earth. The Moon - in full: First of all, although I said that the surface "may resem... (more)	—	about 4 years ago
Question	—	The Earth and Moon resolidify under a bluer star, their outer layers evaporated and burned away. What do they look like now? (This is the third in a series of questions, starting with Moved into further orbits to protect them, how much damage do Earth and Moon take when the Sun expands? and How soon does the Earth's surface re-solidify after the red-giant Sun is replaced with a different star?) The story so far: To recap... (more)	—	about 4 years ago
Answer	—	A: Could these new wormholes be used as a hammer space? I've read the paper written by the researchers in the article you reference. I've also read its follow-up: "Creating a Traversable Wormhole". Disclaimer: I'm not a physicist, and much of it goes over my head. I don't think I can give you a simple yes or no answer, but the situation looks like this:... (more)	—	over 4 years ago
Answer	—	A: What can these negative-mass-free wormholes be used for? If the ends of the wormhole can be moved, then maybe terraforming Let's imagine your explorers have travelled to a new solar system. It's got a type G sun, pretty much identical to our Sun. There may or may not be aliens living on an Earth-like planet in the habitable zone, in fact you aren't sure i... (more)	—	over 4 years ago
Question	—	How soon does the Earth's surface re-solidify after the red-giant Sun is replaced with a different star? (Note: This is a follow-up question to my previous one: Moved into further orbits to protect them, how much damage do Earth and Moon take when the Sun expands?) Thanks to clever stellar engineering by a group of aliens (see below.), the Sun has been induced to end its red giant stage early by turnin... (more)	—	over 4 years ago
Answer	—	A: What tech would aliens use to harvest/alter our star and why? If "the local star" isn't our Sun, I think I can help you. Actually, I think I can even if it is the Sun, but in the far future. In "The End of the Sun", two such scenarios are described. These will occur naturally during the star's lifespan, without the need for any third-party intervention, advanc... (more)	—	over 4 years ago
Question	—	Moved into further orbits to protect them, how much damage do Earth and Moon take when the Sun expands? Short version A far future catastrophe burns/melts away large chunks of the Earth and Moon. For reasons related to my story's fantasy elements, the remains of the Moon have about one fifth their original diameter, and I'd like to know what the corresponding reduction in size for the Earth would be. ...
