SpaceX is not available to purchase in an open market. Soon Slack may be. If they were both publicly listed, maybe their market caps would means something. Estimated private valuations, not so much info there.

How do you expect to compete with fully reusable boosters a la SpaceX? Are you building your own and when do you hope to have them delivering paying payloads? Or does ULA hope to buy reusable rockets from Blue Origin, not just engines?

" They are incentivized to succeed, and so they do." Well, they have succeeded so far due to a huge amount of capital and talented people working very hard. I think more importantly is, if a system fails, that it shrinks in power

This is the same experience one has with an ICE engine and manual gear box at higher RPM. Much easier to drive aggressively in that mode for reasons you state.

Cost plus contracts are a huge problem for efficient public funding of projects. Also see NASA'a SLS rocket versus SpaceX's falcon heavy. SpaceX's next generation rocket is going to be so far ahead of the SLS in capabilities

Like people retired people who will spend all day and most of their disposable income sitting in front of a slot machine pushing a button. I imagine that is not what most of them wish they were doing with their lives.

Of course the housing crisis has many factors contributing to it. This is a major one. If a place has a majority of renters, has a prevailing political culture of socialism and activism, and the rents start going up fast, you likely end up

I don't know your background, so it is hard to know what to recommend. If you have a PhD in a subject area then in theory you should have enough general knowledge to be able to effectively read a recent review article explaining the st

The magnetic field also gets very weak (90% drop in intensity and the magnetic pole way down near the equator) quite often. These are call magnetic excursions. They happen at an average frequency of maybe 50 thousand years or so with a high

Previous estimates on the time it takes for a flip to happen are in the 1000-30000 year range[1]. That paper gives a 7000 yr average but the variance on the time it takes is likely large. The Berkeley article you linked to is on this paper[

Articles on the fear of the Earth's field flipping are, as expected, not very realistic. The best current knowledge is that it takes thousands of years for the field to flip and the current fluctuations are within normal bounds. The wi

I think the name is brilliant as one expects that the Gell-Mann effect is named after its primary creator, Murray Gell-Mann. If you know about the topic in detail, one knows that is not the case. A similar situation to what the Gell-Man eff

US nickels have had the same composition (75% copper and 25% nickel) since first being issued in 1866. Hopefully people who feel that using it as a structural metal is a bad idea due to its toxicity are quite wrong and hundreds of millions

In the 1970's we saw the rise of "safety first" as a philosophy for life. By the 1990 most people believed it. Safety first as a prime directive leads to doing nothing in the end. Almost none of previous tech advancements fro

Unless they also have their own lane/road. Maybe in built up areas we will have to build tunnels for them.

by njarboe 8y ago
Yes. With cheap tunnels one could hope to plan for many exits and a large network that goes everywhere. Like a road system, but underground. Imagine an early city where all the roads are really just paths in the dirt that are completely rut
