I don't see why they would use helium. Hydrogen would be much easier to deal with since it can be readily extracted from the hydrogen sulfide clouds. There wouldn't be any Hindenburg's since there's no oxygen in the atmosphere to react with.

It's also more bouyant, so the gas bag would be smaller for the same weight, and you could launch it from earth with less delta V.

Is that a 122 L tank or is it the volume of Hydrogen at STP?

Why not compare the distance you could travel with 122 L of liquid Hydrogen against 122 L gasoline vapors? (of course, that wouldn't fit with the narrative they are trying to put forward)

There are a bunch of Native Americans who might disagree with you, there.

*2y dark matter mass to our y dark matter mass*

It would be 18y dark matter to Milky Way y matter.

So then really what they are confirming is that inference; that matter and dark matter are in a 1/9 ratio, and that if our galaxy has x stars and Andromeda has 2x stars, then Andromeda will also have 2y dark matter mass to our y matter mass.

That seems to be a more interesting finding.

I've been taught that Andromeda has approx. 2x as many stars as the Milky Way. I learned this years ago, as far as i can remember.

Is it really surprising news that a galaxy with twice as many stars is twice as massive? Were these researchers just fact-checking?

I'm still bitter about Aureal.

Protecting from solar radiation is great, but i understand that the greater threat is cosmic rays. Solar radiation is somewhat easy to block, because you just put a light element shield, like hydrogen tanks, between the astronauts and the sun.

Cosmic rays are much harder to shield from because they are so high energy. They also come from everywhere, so require a omnidirectional shield.

3d-printing of guns: the quickest way to create legislation regulating the sale of bullets.

you were also missing half your roof. By your logic, you shouldn't put a roof over your head because a tornado might damage it.

PS. Homeowners insurance will cover and replace the solar panels that are damaged.

If a tree* lands on your roof, solar-panel covered or not, you've got enough problems. But that's what homeowners insurance is for.

*or anything heavy enough to break a solar panel

As you say, better generators cost more, and the power they generate is significantly more expensive than grid power. You would need to have a lot of power outages and spoiled food in order to break even on the cost during the usable lifetime of the generator.

A $2-3k generator and the cost of instillation is about 30% of the equipment costs of a solar installation, and the equipment is getting cheaper all the time (labor costs are flat or increasing). And a solar installation will pay for itself half way through it's warranted lifetime (about 1/3 of the way through it's usable lifetime).

Well I don't see what's so weird about displaying them on a bookshelf or table. Maybe with a nice tablecloth on top, and some candles and incense.

It's also a good place for me to put my sacrifices and to focus my prayers
