Why people who compare about scientific accuracy never actually know anything about science?

Also, not one object moves. Shouldn't they be sucked in by the black hole.

Not if it's in a (mostly) stable orbit.  It's just a gravity well like any other, provided you don't pass the event horizon.  Replace our sun with a singularity of the same mass and all that would happen is it'd get dark about 8 minutes later and we'd start the process of freezing to death.

Black Holes...not necessarily black. Especially when there's infalling matter (like, you know, an accretion disk, as was mentioned in the game), for a number of reasons.  For example, there's something called the photon sphere. It's another boundary outside the event horizon where photons assume circular orbits.  Stuff falling through can disturb them and send them away from the singularity. Then you have the infalling matter itself getting ripped apart and accelerating, emitting EM in the process. Lots of X-rays mostly, but stuff in the visible range is also possible. Plus, it's believed they all radiate thermally.  It's called Hawking radiation.  There're other effects at work too that can produce visible EM, as black holes can have magnetic fields.  Very strong ones too.

yeah but it doesn't seem like the debris or the collector ship circle the black hole.

But there could be a black hole on the other side so that gravity pull is equal in both directions. maybe.

Of all the scientific inaccuracies packed into this game and science fiction as a whole, you zeroed in on something that is actually scientifically correct. Congratulations, sir. That is not an easy feat.

Did they really show us views of the area long enough to require animating that?  There's a lot of cuts and the Normandy is dashing about, and the exact distances and scales are hard to judge, so it's not really necessary detail for the scene.  I can recall some stuff drifting about some, however.  Mostly, though, I was disputing the notion that a singularity is some sort of cosmic vacuum cleaner, not whether orbits and suchlike were depicted accurately.

Oh, and also: someone in one of the cutscenes brings up the idea that the Collectors might be using ME fields to maintain their bases' position, so it being stationary isn't an issue (hardly scientifically accurate, but it doesn't violate the established rules of the ME world).

its all about perspective. the earth moves around the sun at great speeds, but if you're sitting in orbit you would be able to tell because you are moving at the same rate. same with the accretion disc, no doubt its moving you just can't tell because you are moving with it.

[MobiusTyr]

Release all logic. Most of you won't make good writers/game makers. Science = FAIL    Made Up Cool stuff = WIN

It's a static matte painting. Get over it.

Depends on your movement when you "come out" of the mass relay. If you come out with the same relative movement as the relay then it could work but.. I don't know, mass relays **** up my thoughts of the movement. Let's just say there's a mass effect field.

lol, burn.

[Pauravi]

Clearly the OP doesn't know much about black holes :-/

Look up "accretion disc" and "gravitational lensing".

[Joshua Hawkeye]

So I couldn't help but notice when you go through the O4 relay to fight the collectors the black hole is letting light escape, in all actuality this is scientifically impossible.

Scientifically impossible? Some scientists may have said that it is impissoble, but the idea of earth circling the sun and not vice versa was scientificly impossible for thousands of years untill Copernicus decided to reject Artistoles' theory.

(in Science, nothing is possible or impossible, there are just theories)

And then, this game is not science-ish. It's a work of fiction, and that 'black hole' is part of the artwork.

And thirdly. Element 0 (an Atom without Protons) is probalby scientificly impossible too).

Depends on what you mean by "atom":

An active, feeding black hole is VERY bright actually. More so if it is emitting a jet.

True, nothing escapes them, but they also move with such speed, and force that they can " eject" things from the event horizon with great force. things outside of the zone can still be " flung off" and ejected as well.

I forgot "where" it is, but a nearby galaxy has a super massive black hole that is emitting such a powerful jet, that the jet is actually blasting entire solar systems out of the galaxy.

We know almost nothing about black holes. Calling a science fiction game inaccurate about it is rather... Strange.



I rather like how the design turned out. Looks menacing and imposing, and that's what counts. Aside from that, untill anyone in the real world actually gets near a black hole we have no idea how they look anyway.

I'm pretty sure Stephen Hawking and just about every other physicist would disgree with you there.

I think that is supposed to be the supermassive blackhole that forms the nucleus of our galaxy. The reason why the Collector base isn't getting sucked in is because it's a difference of perspective. It's actually very far away, but still enormous enough to look fairly large.

It's just a black hole.  They're in the galactic core, which is a region, not at the exact center of the galaxy.

Within the first five minutes of the game, Cerberus reconstruct Shepard's body, including neural pathways and in-tact memories, from nothing but a DNA sample, and this is the scientific inaccuracy you pick up on?

I think you need to go back and watch that video again. Unless you're calling an almost completely intact body a DNA sample, which I guess is technically correct.

Two words "Hawking Radiation".

Please don't help. Hawking Radiation is not visible light and it is VERY faint -- so faint that it has never been observed.
