Re: C/2013 A1 (mars)

Could you try the attached file that works well for me ? (it is zipped because files with ssc extension are not allowed as post attachments) :mrgreen: Yep, this one works for me as well. Thanks. I don't see the difference with what I tried. It's confusing. Maybe the file encoding? Update: it does n...

Re: C/2013 A1 (mars)

This does not work for me :(

How could I know what goes wrong? I see nothing in the console. It just seems that the file is just ignored (and yes I did put it in the "extras" directory).

Re: Oculus Rift (Virtual Reality Headset)

It is totally fine, and it's not just about gaming, it's about simulating the world. People have been doing that ever since they painted animals on cave walls.

Also, simulating the world is also what Celestia is about. VR could just make it even more realistic.

Oculus Rift (Virtual Reality Headset)

Oculus Rift is a virtual reality (VR) headset designed in 2012, founded on kickstarter and presented in CES 2013. Everyone who has tried it say it is awesome and provides a total immersion. It might cost only about 300$. Check this video out for instance: http://www.youtube.com/watch?v=KJo12Hz_BVI ...

Re: Open source relativistic game engine by MIT game lab

http://www.spacetimetravel.org/ Have a look at the many videos they have done. Unfortunately the German site is more up-to-date. Well I'm kind of disapointed by what I see there. I don't remember where I read that, but I once read that when travelling at a relativistic speed, stars in the sky gathe...

Re: Is a black hole a perfect sphere?

IMHO, the horizon sphere is a perfect sphere, because it's not really physical, it's a geometric concept. As far as the black hole itself (the matter it is made of, whatever form it has), we don't know and we can not know since it is inside the "no-return of information" zone. We might as ...

Open source relativistic game engine by MIT game lab

Check this out:

Wouldn't it be cool if we could travel in Celestia at relativistic speed and see accurate relativistic effects?

A thermonuclear motor on the moon

Quite an amazing concept: digging huge caverns on the moon, put some water in them, blow up fusion bombs, and get the generated steam energy with turbines. http://monstermaschine.wordpress.com/2012/07/23/a-revised-version-of-the-fusion-steam-machine/ I like the way the guy is capable of "thinki...

Pan-STARRS

What can we expect from Pan-STARRS ? From what I understand, this project does astrometry so it will compute the exact position of a lot of nearby objects. « In addition to the large number of expected discoveries in the asteroid belt, Pan-STARRS is expected to detect at least 100,000 Jupiter Trojan...

I hadn't realized that. Thanks for pointing it out.

I hope I'll still be alive when the Gaia survey is published.

Re: 40 million new stars.

Had you do the test with magnitude equal to 15.15 ? I can only add stars up to magnitude 12 (unless there is something I miss). It seems to work fine. Moreover, there is no reason why the newly added stars would be all visible in the same time for a normal magnitude. 800 Mo on hard disk, imagine in...

Re: 40 million new stars.

Imagine for 40 millions stars :!: It gives, twenty more or 40 Mo x 20 = 800 Mo for the file... To me 800 Mo might be Ok. And we don't have to add the whole catalog anyway. Several subsets can be released, depending on how much disk space the user is willing to give to Celestia. I worry more about C...

Re: 40 million new stars.

You put a lot of smileys but seriously: can we hope to add those stars in the database soon? Would it severely slow down the computer? :?:
