So here how it will work, I will post a number of intesting topics on space/time/science and the first one to reply will decide which one to debate on first. If you have another topic on mind share that one too. Got it, ok, good!
Please point out an errors in the following theories because Im sure I will make them.
Grandfather Paradox: So this bad boy is one of the most well known time pardoxes. Basicly you (the grandson) go back in time killing your grandfather. Thus in the future up till the point you traveled back in time you along with your father would not exist. Due to the fact you killed your poor old grandpa before helped concive you. Createing the paradox of "How would you kill your grandfather because you did'nt even exist?"
Now I have heard a few theorys to explain this, one being every seperate action creates a seperate parallel universe, thus allowing room for you not to exist in one while you exist in the other due to the fact your grandfather is'nt dead. I have had trouble wrapping my head around that one, frankly im not sure how just one action would create a seperate universe, for me that requires something supernatral for that to be possible. Another being that you since your traveled back in time you would now seperate, outside the normal flow. leaveing you not effected by this paradox. And another one that another forum user brought to my attention back on the old forum on how this Paradox is'nt possible. I'm not exactly sure how to explain this one, but essestially you would not be able to kill your grandfather because time would prevent that, perhaps you slip/fall and break your neck before getting the shot off, things like that.
Time Dialation: Hafele and Keating, in 1971, flew caesium atomic clocks east and west around the Earth in commercial airliners, to compare the elapsed time against that of a clock that remained at the US Naval Observatory. Two opposite effects came into play. The clocks were expected to age more quickly (show a larger elapsed time) than the reference clock, since they were in a higher (weaker) gravitational potential for most of the trip (c.f. Pound, Rebka). But also, contrastingly, the moving clocks were expected to age more slowly because of the speed of their travel. The gravitational effect was the larger, and the clocks suffered a net gain in elapsed time. To within experimental error, the net gain was consistent with the difference between the predicted gravitational gain and the predicted velocity time loss. In 2005, the National Physical Laboratory in the United Kingdom reported their limited replication of this experiment.[16] The NPL experiment differed from the original in that the caesium clocks were sent on a shorter trip (London–Washington D.C. return), but the clocks were more accurate. The reported results are within 4% of the predictions of relativity. (To lasy to write, sorry c/p from wiki)
Universi, as in plural: Some speculative theories have proposed that this universe is but one of a set of disconnected universes, collectively denoted as the multiverse, altering the concept that the universe encompasses everything.[13][70] By definition, there is no possible way for anything in one universe to affect another; if two "universes" could affect one another, they would be part of a single universe. Thus, although some fictional characters travel between parallel fictional "universes", this is, strictly speaking, an incorrect usage of the term universe. The disconnected universes are conceived as being physical, in the sense that each should have its own space and time, its own matter and energy, and its own physical laws — that also challenges the definition of parallelity as these universes don't exist synchronously (since they have their own time) or in a geometrically parallel way (since there's no interpretable relation between spatial positions of the different universes). Such physically disconnected universes should be distinguished from the metaphysical conception of alternate planes of consciousness, which are not thought to be physical places and are connected through the flow of information. The concept of a multiverse of disconnected universes is very old; for example, Bishop Étienne Tempier of Paris ruled in 1277 that God could create as many universes as he saw fit, a question that was being hotly debated by the French theologians.[71]
There are two scientific senses in which multiple universes are discussed. First, disconnected spacetime continua may exist; presumably, all forms of matter and energy are confined to one universe and cannot "tunnel" between them. An example of such a theory is the chaotic inflation model of the early universe.[72] Second, according to the many-worlds hypothesis, a parallel universe is born with every quantum measurement; the universe "forks" into parallel copies, each one corresponding to a different outcome of the quantum measurement. However, both senses of the term "multiverse" are speculative and may be considered unscientific; no experimental test in one universe could reveal the existence or properties of another non-interacting universe. (Again from wiki, im sorry)
Dark Matter, you know what our "friends" the Reapers use: Perhaps I am generalizing too much and im talking about two completely different things, but our favorite game Mass Effect uses this theory/fact (don't know which). Scientists say the Universe is constantly accelerating as objects are pushed apart by some invisable force. Dark Matter is now accepted as the reason behind it, this type of matter is invisable to the naked eye you would have to use a certain type of electron telescope to see it.

AntiMatter: Not to be confused with Dark Matter (from my understanding they are completely different), but in particle physics AntiMatter is simple the opposite of normal matter. (I'm not exactly sure how it is the opposite of normal matter, perhaps it could just have an entirely negitive charge.) There is considerable speculation as to why the observable universe is apparently almost entirely matter, whether there exist other places that are almost entirely antimatter instead, and what might be possible if antimatter could be harnessed, but at this time the apparent asymmetryof matter and antimatter in the visible universe is one of the greatest unsolved problems in physics. The process by which this asymmetry between particles and antiparticles developed is called baryogenesis.
Antimatter is said to be the most costly substance in existence, with an estimated cost of $25 billion per gram for positrons[17], and $62.5 trillion per gram for antihydrogen.[18] This is because production is difficult (only a few antiprotons are produced in reactions in particle accelerators), and because there is higher demand for the other uses of particle accelerators. According to CERN, it has cost a few hundred million Swiss Francs to produce about 1 billionth of a gram (the amount used so far for particle/antiparticle collisions).[19]
Several NASA Institute for Advanced Concepts-funded studies are exploring whether it might be possible to use magnetic scoops to collect the antimatter that occurs naturally in the Van Allen belts of Earth, and ultimately, the belts of gas giants like Jupiter, hopefully at a lower cost per gram
No intention to bore you so I will wrap things up. (partially cause I have to take off soon too)
Plant or Animal?: Recently people discovered a see slug that produces chlorophyll. Chlorophyll is one of the substences that plants are catagorized by. So tell me is this Sea Slug a Animal or Plant? And don't say hybrid!

Real Life Reaper?: http://www.foxnews.com/scitech/2010/03/30/terrifying-sea-critter-from-oceans-depths/
And more pardoxes hear: http://en.wikipedia.org/wiki/List_of_paradoxes
One of my favorites is the nihilist paradox.
If you have a interesting theory to post please do so so we can debate it! Nothing to sensitive, we don't want flame wars.
