Don't worry about the quantum entanglement issue. Watch this clip: The Science of Mass Effect 2. Not all is lost. At least one scientist is still supporting it. ;)

In this clip theoretical physicist Dr Michio Kaku addresses also things like biotics, invisibility, force fields, and other Mass Effect 2 SF stuff. ;)

To be honest, I was expecting a group of FOX-news supporters bashing on the unrealistic nature of ME, but as soon as I saw that some of these scientists were actual players of ME themselves, all my worries were quelled. :]



It's really great to see that this stuff is plausible though. Great post!

Wait, where did you read this? I've never heard of any FTL phenomena on such a large scale. Besides, gamma rays are just electromagnetic radiation, and always move at lightspeed anyway. Sheer power output shouldn't have anything to do with it. :pinched:

I'm more interested as to why the black holes at the cores of these "supermassive stars" don't suck the matter of the stars into them.

How about creating a mass effect field by feeding it dark energy? According to Dr Michio Kaku (link in my post above) maybe negative energy (which dark energy may or may not be) is required to open and maintain worm holes. If you use a similar process to cancel some of the curvature near a black hole then maybe... What am I babbling about? These are super massive black holes. I think surviving those is one of the few things that smells like fantasy. ;)

Hm, well, on the subject, what would happen if you got two black holes close together (besides absorbing each other, we're assuming that doesn't happen) and shoved a body at an equal distance from the core of each one?

That's a good question. I've read recently that theoretical physicists are creating a simulation of that using a super computer. I think the results are not in yet. ;)

IIRC Kip Thorne was leading the project or somehow involved. Not sure, though.

If you are interested I can dig up an interview with a physicist about that subject.

I've found it. Unlike what I wrote earlier results are in and Kip Thorne didn't have anything to do with it. In short this is it...

The universe is expanding at an increasing rate. It is accelerating. Everything is moving away from us, except the Andromeda galaxy, which is on a collision course. In two billion years they will meet for the first time. Because space between star systems is huge actual collisions can happen, but are very unlikely. It will stir things up a bit, though. Much like a pendulum Andromeda will pass us and bounce back and that repeats over and over again, until after 5 billion years the two galaxies will finally merge permanently. This process will be violent of course. The merged galaxies will be called Milkomeda (pun intended, but no kidding). Hehe.

Each galaxy has a massive black hole at its center. In the end the two black holes will merge, but before that happens one will kick the other away a bit. Two years ago a computer simulation ran that shows that this scenario is likely to happen.

This is consistent with observations of other galaxies that already have merged. Such galaxies have an ellipsoid shape. But due to the age of both galaxies "Milkomeda" will look a bit different, because there is less gas in it than earlier merged galaxies. In the Milkyway and Andromeda more star formations already took place using that gas.

The guy that knows a lot about this is Professor Abraham Loeb.

Source: What is the Far Far Future of the Universe? (Abraham Loeb).

Because the universe is expanding our (merged) galaxy eventually will move away from itself too. Because the nature of dark energy is yet unknown (cosmologist Max Tegmark calls dark energy "a code word for our ignorance") we are unsure what will happen. It can end in one of three scenarios: the Big Rip, the Big Chill or the Big Crunch. This last one was ruled out earlier, but is under investigation again.

Source: What is the Far Far Future of the Universe? (Max Tegmark).

According to Lee Smolin the story does not end that simple. He and others believe that black holes not only have a role at the center of galaxies, but black holes also have a role in the creation of universes. Much like natural selection in biology there is something going on like that during the creation of universes by black holes. Some universes will fail and others survive due to the condition of the state of these black holes during the creation of these universes.

My apologese, I should have said believeable instead of possible. Poor choice of wording on my part. But yes, it isn't possible due to the fact that mass cannot change. It's still believeable though, which makes it fun.

I swear I've read a few article about the mass of particle being reduced.  Not with Eezo of course but reduced all the same.

The FTL travel in ME is via worm holes, so there is no violation of the speed of light. They don't travel faster than c, but create a shortcut in the universe.

PS: mass can most certainly be destroyed, e.g. electron + positron, and mc^2 is rest mass only.

Wormholes? Are you new?

Certain quasars and even galaxies can appear to be going at 8 times the speed of llight because of our relative motion and the angle the light arrives, but it is an optical illusion

The black holes are formed after the stars go supernova.  They don't reside in the star while it still does fusion, which is what keeps it from collapsing in on itself

Black holes, if spinning while they are formed can form the shape of a ring.  It would be quite safe to pass through the center of this ring.  Also,  I have read that one passing through should not expect to come out the other side in the same region of space or even in the same time

The body, say a comet or planet, would split and each half would enter the hole it is closest too.

Chances of that happening are slim. Kip Thorn says that the earlier idea that "the traveller" would become infinitely thin and long or that one could pass are both unlikely. Instead forces would rip the traveller appart from all sides. He says that in reality we now know that one would be stretched and squeezed from all sides in a chaotic manner and at an ever increasing rate. One would die. ;)

These are called Kerr black holes, and unfortunately they're (probably) unstable once outside influences are introduced:

Yeah. He does a good job in trying to explain stuff in terms like we can understand. But the problem is that things are rapidly changing in the past two decades, so one has to be careful with his older publications.

In the clip he makes a little booboo when he sums up what stuff is contained in the universe. He knows his stuff, but it was just a slip of the tongue. The correct numbers were 4.6% ordinary matter, 23% dark matter and the rest is dark energy. He accidently used the same percentage for both ordinary matter and dark matter. That may have caused some confusion I think.;)

I know that, but it's not what Lord's formulation implies.

In the post above yours I've posted a link to an interview with Kip Thorn. He studied at the university to which Kerr was connected at the time Kerr dreamed up his theory. Kip Thorn says that these black holes are real, but unsuitable to travel though space or time. In fact in part 2 of that interview he tells that the super massive black hole at the center of our galaxy is a Kerr black hole. According to Thorn it's center (the singularity) warps spacetime into time and that causes that anything inside its horizon cannot escape and will be sucked into the singularity. Because of its spin the spacetime around that black hole warps violently and is responsible for a quasar that spits out giant beams of energy.
