Re: Show off your work

I did some more work on the calibration tools for our meteor cameras, adding support to draw a RA/DEC grid on the images captured by the cameras.  This makes it possible to make some neat timelapses: https://www.youtube.com/watch?v=88dJXfdx8lA https://www.youtube.com/watch?v=Q_LJO2vAJUE This also ma...

Re: Science and Astronomy Questions

Absolutely. Birds do it so well that they can even do it in normal gravity. It's just that humans aren't built to do it well without aid like special clothes.

Re: Dreams you've had

I had a strange dream a few years ago.  In the dream the many-worlds interpretation of quantum physics was real in the sense that, in the case of Schrödinger's cat, the cat is both alive and dead but in different realities, and you don't know which reality you're in until you open the box.  The real...

Re: Asteroids, meteors, and meteorites

Our meteor cameras recorded an extremely fast moving meteor just after midnight last night.  This was in northern Norway with the sun sitting at the horizon at the time, so the sky was bright, but the meteor even brighter. What's really interesting is that it appears to have been interstellar with a...

Re: UFO Sightings and Possible Explanations

Indeed.  Such things would in almost every case be found by civilians, who would in most cases report it to civilian institutions (including the press).  Maybe there is a misconception that the military can detect everything that falls to the ground globally with radars and spy satelittes and so on,...

Re: UFO Sightings and Possible Explanations

So the claim is that there's been a cover-up of something that has happened globally for decades.  And the sole source is some military guy.  The more absurd the claims, the less anyone with credibility will bother to argue against them.  And that will, of course, be taken as evidence for the cover-...

Re: Asteroids, meteors, and meteorites

The Perseids hit at 59 km/s, the Leonids at 71 km/s.  This is fast, even for meteors.  These showers produce short-lived meteors, usually a fraction of a second (but when the radiant is low in the sky, long meteors perphaps lasting a second or even more might be seen).  On the other hand, these fast...

Re: Science and Astronomy Questions

If there is no way to unscramble the information, how is that different from information not lost? Like, the idiot's super efficient compression algorithm for a binary stream would be to count the number of 1's and 0's, and leave it to the decoder to arrange them back in the proper order.  In a sens...

Re: Asteroids, meteors, and meteorites

Yes that is what was reported on the news, likely it was just a coincidence that it happened around the time of that meteor shower then? The amazing thing is that it actually landed inside a person's house, the odds of that happening must be incredibly low. Originally I thought maybe space junk, bu...

Re: Asteroids, meteors, and meteorites

Yes.  Virtually all meteorites are that old and from an asteroid.  It was a rocky meteor which has some iron, but still a meteorite low in iron.  It was likely not hot, but rather just warm.  Meteorites are cold and only the crust gets hot enough to evaporate during the atmospheric entry, but this l...

Re: Science and Astronomy Questions

This is an interesting read and topic! I think you're asking though if a slower than light ship using a warp bubble could escape by having some effect on the horizon. Yes.  It's not really about speed, either, but if given the ability to warp whether you can manipulate the event horizon.  What you w...

Re: Science and Astronomy Questions

As a black hole evaporates away to nothing, does the effect ever become great enough to be important? Not really. Even for a black hole with a horizon the size of a proton, which weighs about 10^12 kg and is radiating so violently that nothing could even fall into it, the rate of shrinking is only ...

Re: Astrophotography

It's been a severe solar storm over the past days, K-index peaking up to 8 and 9 and aurora visible far, far south.  Has anyone taken pictures from unusual areas?

Snow storm instead of solar storm here currently in Oslo, but we've had a decent share of aurora this winter anyway.

Re: Science and Astronomy Questions

Yep, that's the right intuition! There's just one catch, which is what we encountered before: even though hypothetically the distant observer should continue catching signals for the remaining lifetime of the hole, in practice there won't be much of an image or a detection at such late times after ...
