Was that the recent Horizon one? I remember that was pretty good. I might watch it again on series catch up.

Yeah, i remember we mentioned it on the documentaries thread. but the end part especially was the best; where Mersini-Houghton had some theory (cant remember). but it links to how the galaxies are being redshifted away, but even then theres a disparity in their movement.

there seems to be an invisible force of gravity moving them in other directions. and it seems that this could be the gravitational pull of other universes. so thats why when you mentioned scientists being able to detect galaxies on the edge of the universe, then thats what i imediately thought of!

oh by the way are you a big Star Trek fan???

Was Mersini-Houghton the woman whose theory complied with mysterious cold spots in the cosmic background radiation which in her theory were explained by neighbouring universes, and so on. Yeah, I thought that part was pretty interesting too.

And I'm a fairly big Star Trek fan. I watch the show, but I wouldn't call myself a trekkie and go to conventions.

Yeah i think it was her, i cant remember the theory too well but by it was very interesting.

Nah, i'm not a huge fan either, i quite like the orignal series, its still got some good episodes among some really bad ones. but my faviourtie was voyager. not so much a huge fan of the other 3 series, but i think enterprise was the really bad one.

That's ridiculous and highly unlikely. This theory and simulation will be debunked once we understand more about dark matter.

Why do scientists always pretend to know much more than they actually do and the press boosts that further? Pisses me off.

Why is a galaxy merger ridiculous and highly unlikely? We've observed many galaxies that are currently in the process of merging (link).

Anyway, you do have a good point, the simulation may be debunked once we understand a little more about dark matter. And no doubt more accurate simulations will be conducted in the future that will show what was wrong or inaccurate with this one. That's kind of how science works. I'm sure the scientists behind this simulation don't think this is the be all and end all of our knowledge on how Andromeda formed, just a significant step in our understanding.

However, the point of this simulation was to learn more about our local group of galaxies and the simulation's findings showed that many of the properties of Andromeda could be explained with the merging of galaxies. I think it's fair game to report on.

-Edit-

I'm not really in the mood to debate about this right now I'm afraid, sorry Slimebeast.

TNG for me, I love TNG. I don't really watch DS9 or Enterprise, but I think the original series is very good and Voyager is ok.

That's a much more modest way to put it. A statement based on facts only.

Let's not debate, no.

No surprise here. Galaxies are always going to collide sooner or later, thats how they grow. It probably happened also with our galaxy. In 50 Billion Years all galaxys in the local group will collide. Then we have a giant cloud galaxy "milkomeda" which will be the only detectable structure in the whole universe by then, because all other galaxies are going to drift away faster then the speed of light. Future civilisations wont have a clue how the universe looks like.

Incredible, i know it was only briefly mentioned but i find it fascinating that scientists can detect glaxies on the edge of the know universe. but of course Andromeda in itself is a fascinating discovery.


Makes you wonder what else is out there.

Multiple universes across 10 dimensions plus time, according the the highly popular string theory.

We have also pondered this!

String theorie isnt that popular anymore.

 

It has a mathematical beauty but thats it. There is not the slightest indication that the String Theory is true. Also it is so complex even people who have studied physic have problems to understand it.

 

The new Hip theory is the Loop quantum Gravity (LQG).

 

String theory is considered as a theory  which is mainly born in mathematics and a lot of physicist dont think it is right. And as time passes and noone figured out an experiment which could prove atleast one prediction of the theory the popularity of the String theory vanishes.
