Polaris is "up" from the north pole. North is a direction along the surface of the Earth.

One possibility, known as the Hartle-Hawking no boundary proposal, is that if you go backward in time towards the big bang, you reach a...

It's called a sun dog: https://en.wikipedia.org/wiki/Sun_dog

There are a lot of red dwarfs out there, and they live for a very long time. The flares tend to decrease as the stars age. Given the...

In what sense are current Large Language Models (LLMs), which are based on Artificial Neural Networks (ANNs), algorithmic? Do you think...

I've never understood why people say this. Depending how far the planet is from the red dwarf star, the temperature on the side facing...

So, @Line_112 , are you just going to ignore the many redshift measurements of GRBs that have been made? These measurements firmly...

Why do you think this? It is an equal area projection. So dots of the same area will cover the same area of the sphere.

Here is an equal area projection map of the Earth, similar to the GRB map. Areas are not distorted, but of course shapes are. It's not...

What's your point? It's well known that gamma ray bursts are extra-galactic. Look at the Wikipedia page, which says, "In gamma-ray...

What is done here is to release a huge number of sterile male flies. The females then mate with the sterile males and lay unfertilized...

We're building a new factory in Texas with the capability to produce 300 million sterile male screwworm flies per week. This is how we...

I strongly agree with the importance of unit tests. But there is more to it than that. I have had cases where the code writer said...

Thinking about the usefulness of mixing pseudo-code with actual code somehow takes me back to the university in the 80's where we had...

I have had occasions where I was looking at someone's old code, trying to figure it out so that I could modify it, drawing all sorts of...
