An important property of dark matter need to fit what we are seeing is that it also doesn't interact with itself. It would seem weird if it can't interact with itself because of some innate property, but we can't interact wit

Explanations always begin with Galaxy rotation curves because that's how it was first notified that something about our understanding of the universe was off. It's been a long time since then and there's been a ton more data

You've described the search for dark matter as it is performed. There's already a percentage that's been filled in and most theories try to fill in additional chunks rather than as you say "some singular thing".

There's actually an embarrassingly large number of theories for what makes up dark matter. I doubt most people have ever even heard of the form that was ruled out in this article. There's not just a ton of theories, a great number

Everything we know about neutrinos says they move too fast to account for what we see. Doesn't mean that there couldn't be some discovery they completely changes our understanding of neutrinos though.

It'd be a much different problem if everything it was like this. This is more of a "most things we measure" give a heavier reading, but not by any consistent amount. But not all. And very often the scale shows a number when t

I'm really not sure why so many people have such a strong reaction to dark matter theories. Yes, dark matter is the best way we currently have for fitting the data within most of our existing frameworks for understanding the universe.

It can be very difficult communicating people new to the Phoenix area just how much water they need to drink during the summer if they are going to exert themselves outdoors.

You'd eventually have so much energy that the mass energy relation would give you a black hole.

There's two other ways. One is to use a USB 3 to PCI express bridge and then functional pcie USB controller chipsets. I'm not aware of any such bridge silicon existing. The second way is what you said, to skip the bridge and creat

It looks like current pumps fill hydrogen at a rate of about 1kg/minute. A class 8 truck would take more than an hour to fill. At they point just go BEV. https://www.nrel.gov/news/features/2020/nrel-resea

Truck stop pumps have much larger nozzles and pump 6-10 times faster than the limit for light vehicles "and that refueling facilities are exempt from the 10gpm requirement if used exclusively to refuel heavy-duty vehicles, boats or air

You sure can, but it takes a very long time to fill a class 8 truck from a consumer gasoline pump. Doubly so for hydrogen given the slower speed.

We're not talking about a plant being down for a few hours, it'd be a few months for the existing plant to be decommissioned and the new plant to be installed, assuming the existing footprint does not allow the two plants to exist

by russdill 5y ago
Ideally, it would be nice to drop it in as a replacement for an existing plant. However, it may be that the grid cannot sustain the existing plant being shut down without new capacity already in place and there's the more problematic i

I sometimes wonder if the laws governing the universe are a bit like a Taylor series. An infinite set of terms each with a smaller effect on reality quickly approaching zero.

I really think you are misreading the paper. They are specifically calling out that they aren't claiming to be Maxwell's demon and they the system quickly reaches equilibrium and the power drops to zero.

That shouldn't be a problem to implement on an FPGA with a tiny bit of extra logic.

by russdill 5y ago
Sounds interesting. Any citations where I can read more about those effects?

In circuit programming is just such a huge step forward. You still need separate programming hardware, but you don't need to pop the chip out. Beyond that, a few hundred bytes is usually enough for a simple bootloader. That tends to ac

I feel like from reading through this thread is that everyone has a body that manages hunger and metabolism differently.

The question is how much of that cost was involved in getting it to fit the launch constraints? The materials chosen, the unfolding method, etc. On top of all of that, it has to be made so that it absolutely cannot fail. Imagine instead lau

I was on the phone about 40 minutes. The rate in the end was the negotiated rate from the insurance company. The amount of time and effort involved in finding out how much something will truly cost certainly seems like an intentional featur
