A few minutes for what? Once the capsule, or cable (or any part of them), crosses the EH, it disappears to the external universe. No electron, photon, proton, quark, etc can go from the inside to the outside.

Baring some really weird Hawking radiation concepts, which take trillions of years to get any information out from a reasonable size BH.

Yes, and no. The “point” that everything is expanding away from, wasn’t a mathematical point. It was the whole universe, and is now everywhere. The center of the universe is now right here — no matter where you point a telescope, you’re pointing away from the center.

The moon’s motion away from the Earth is not a constant rate. Every month, the moon gets closer by about 13,000 miles, then it gets further away by about 13,000 miles. On average, over many decades, the distance increases by about 1.5 inches per year.

But that 1.5 inches doesn’t matter for getting energy from the moon. The moon going around the Earth is what cause tides, and we can and do get energy from tides.

No, the gravity would not act as one large mass. Imagine a rope made from one thin strand of spider silk … there would no effect at all. However, from a large enough distance, the Earth-Moon system appears pretty much like one gravitational point. At about 100 times the Earth to moon distance.

A real expert on Reddit? That’s a rare thing. Q: if the added mass was solid iron or silicon, so that it would sink to the core, I understand that the solid core would grow. But would the outer gassy layers also grow?

If Jupiter was 10X more massive, the near-by asteroids would change their orbit by less than 0.5 AU. They are already at least 4.2 AU from Jupiter. Earth's orbit would change by less than 0.05 AU, but that's still a huge impact on the seasons.

No, bigger doesn't mean more interference. The size of Jupiter is trivial compared with the distance to asteroids. More mass is what does it, not just more size.

And I'm sticking to my statement that with more mass, Jupiter would shrink. At least until it starts nuclear fusion, at about 80X current mass.

Reply to Researchers have found that lab mice are more likely to survive a flu infection if they are fed grain-based foods rather than processed food: after being infected with influenza, all of those fed the highly processed diet died, all the other have recovered by giuliomagnifico

Can somebody help me here? I scanned the article twice, and couldn't find how many mice where in each group. There's a hint from the survival graphs, that it might be 12 in each group.
