Originally written by Student of Trinity:

Dammit, Jim, I'm a physicist, not an oncologist.

I believe, though, that the crucial feature of a tumor is that it manages to fill itself with blood vessels that connect to the rest of the network, so that its interior cells get supplied with oxygen. Without that nasty capability, a mere mass of cells could not keep on growing, because the inner ones would starve and die.

So since the universe does not seem to have any blood vessels, or anything like them, I'd say the tumor model is a bit off.

Since this has turned into the topic where we all show off our scientific knowledge, I may as well say that there are actually 6 features that nearly all types of malignant tumour must have:

* Sustained angiogenesis (blood vessel formation) -- the one you mentioned. Each cell has to be within a certain distance of capillaries in order to receive enough nutrients to keep growing. Cells more than a millimetre or so from the nearest capillary bed don't grow very well.

* Growth signal self-sufficiency. All animal cells ordinarily need external signals in order to survive and grow (mostly in the form of proteins or other hormones, either circulating in the blood or secreted by nearby cells). Normally, the cells of tissue from an adult organism receive only enough growth factors to keep the tissue in a steady state, and the signal will be turned down further if excessive growth of that tissue type occurs. Certain mutations allow a cell to proliferate even in the absence of growth factors.

* Resistance to growth-limiting signals. This is pretty much the same deal as above (signals that limit growth are produced, and more are produced when the tissue overgrows), but the actual molecules involved are different so two separate genetic mutations are normally required to confer both, which is why this gets its own category.

* Ability to proliferate indefinitely. Certain internal processes such as telomere shortening set inherent limits on the number of times most cells can divide before they become "senescent", stop dividing and eventually die. However, some genetic mutations allow these limits to be bypassed. If this explanation sounds like a bit of a handwave, that's because it is; the processes underlying cell senescence are relatively poorly understood.

* Resistance to cell death signals. Normally, damaged DNA and abnormal protein expression can be detected by various mechanisms involving both the cell itself and other cells, and signalling pathways are activated that cause the cell to die.

* Ability to invade and spread through tissue. This often involves the production of enzymes that break down the extracellular proteins that normally hold cells in place.

Of course, in non-solid tumours such as the leukaemias and lymphomas, a couple of these factors aren't applicable.

Weak acid and strong acids don't differ in corrosiveness. What you are thinking of is molarity.
Depends on what it's corroding. Human tissue isn't strongly acidic or alkaline, so a strong acid will damage it more severely than a weak one. With a metal or base, though, a weak acid will work almost as well as a strong one, although probably more slowly.

Actually, the sulphates in lava decompose to sulphur dioxide at high temperatures and react with water vapour in the air to produce sulphuric acid, so your example is poor, even if your point is good. :P

After Kunnislutz, I try to take out Lucivius. I am stopped by his irritating barriers. I try to pick up Tiberius and he says he is too tired. I try looking back into the Lucivius's castle, and the game seems to think that I have Grimly along?
What am I supposed to do to pick him back up?
I'm pretty sure that by continuing along that conversation path and asking about the right things, you're eventually given the opportunity to tell him something to the effect that fighting Lucivius would be a perfect way to die. Do so and he'll join you.

You might have to do something else first, though; I'm not sure.

Krill actually consists of several different species, although when people say "krill" they're usually thinking of the Antarctic krill in particular.

Anyway, if we're talking about the Antarctic krill in particular, you may or may not be right. The human biomass is about 300 million metric tonnes, whereas Antarctic krill biomass is estimated as 100 to 800 million metric tonnes. In any case, we certainly beat every other land animal.

cool

it is like before the universe appeared.
maybe our universe is the result of, lets say, the "explosion" of a singularity? what about that?

It sure did, at least as far as we can tell. If you read a few books about cosmology, you'll find a lot of them talk about the "Big Bang singularity".

Oh, pshaw. Time is just another dimension, a direction of movement. There's nothing special about it, any more than there is something special about up or down, left or right.

It's not totally impossible for something to exist outside of four-dimensional space (how would we be able to say that?), but it's pretty hard to conceptualize.
It's easy enough as long as you're willing to add an additional timelike dimension; a kind of "meta-time" that takes priority over our time. By analogy, consider the process of writing a book. The book has a timeline in which events happen in a certain order, but by existing in "real" time outside the system we're able to alter things occuring at any point in book-time.

Considering the sequel is apparently destined to take place largely in slith lands, that leads to mental images I'm not sure I want to contemplate. O_o

I rather like Hume's argument against miracles. A miracle, by definition, is something that can't happen. Once something has happened it's no longer miraculous. The fact that we don't know how or why it happened is beside the point.

(Yes, I'm aware Hume's argument is more elaborate than that, but that's the basic fallback part of it.)

Well, for one thing, the human species has a greater total biomass than any other species on Earth. Whether that counts as "success" is another matter.

You can create a new character in some towns. In VoDT, I think you can do so in Fort Talrus.

There are also NPCs that can join your party, but only for the duration of specific scenarios.
