Greg Beetham's recent activity

  • Tabby’s star has been classified as a normal main sequence class F3 star, which implies that it isn’t unstable or a variable etc. The sequence from largest/brightest O-B-A-F-G-K-M to the smallest, ...
  • That is an improvement, the program has smoothed the sky it seems and found lots of stars too, if you want to do camera based exposures and keep tight stars there is a good mount for the purpose, ...
  • It would be locked into a very regular brightening/dimming pattern anyway, nothing like the behaviour of this one.
  • I’m obviously having a bit of a leg pull with the ‘armada’ idea but a bunch of objects on a direct line between the star and us is making more sense to me than any other idea I’ve seen so far. The ...
  • I think gravitational lensing requires large masses, a BH in line of sight probably would do lensing but that isn't what the various articles are saying, they are talking about dimming and ...
  • I don’t think cosmological structure comes into this issue myself, in any case space time seems more fluid and malleable than the envisioned ‘crystal’ structure needed to support string schisms ...
  • No you wouldn’t see the structure directly but they have looked for any signs of thermal/infrared signature wavelengths of second-hand emissions that such a structure would emit and they found ...
  • Um the sun is 8 minutes and 20 light seconds away from the Earth.
  • Interesting Lyle, and well executed except for perspective, the top, bottom and side edges would be millions of kilometres further away than the section right in front, thus those sections would ...
  • Alien armada or not, it’s something on a direct line of approach between the star and Earth, a large group or swarm of something strung out in depth fore and aft, some large and some small, and as ...
  • The masking agent could be reasonably small if it’s much closer to Earth than it is to the star but how does it maintain its line of sight interference with the star? the only explanation is that ...
  • I suppose they could care less if they wanted too but they only care less by the usual amount this time, i.e. on a scale of 10 they only care less by say a 7, but if they really wanted to care ...
  • That's a jolly decent pun. If they pretend to assume the throne of god they also bear the responsibility of office, there might still be god cops that will find out about their little game of idle ...
  • I’d say bell pepper (after a search) would be the same thing as what we commonly know as capsicum, the pics look the same anyway. It’s just a flavouring when chopped up into small bits for ...
  • I had read some of Asimov’s novels a long time ago I’m not sure if I read that one, I’d have to go read the Wiki article when I get a minute to see if it jogs my memory, I also read Heinlein and ...
  • I’d be tempted to observe that any civilization that is capable of ‘creating’ their own matter would be so close to being a god that they wouldn’t need to create matter anymore, it wouldn’t be ...
  • Yes ok, the strength of the Sun’s gravity is 28 times 1g on the surface of the Sun, but only 0.0006g at 1AU so the gravitational force at that distance is not a lot but is still strong enough to ...
  • I made a pizza the other night and you could just see spaces through to the layer of shredded ham because of the black and green olive slices scattered over it before the pickled jalapeno, ...
  • I really doubt there would be enough material of any kind in the entire solar system to build such a thing, how big would each individual collector be? moon sized? That’s probably millions of 3500 ...
  • I don’t think a single one even got ruffled.
