[quote=Mammalia] One of the main reasons that scientists do science is . And what I said is what would most certainly be true the factors behind it were true. There is the that the actual universe is smaller than the observable universe, certain factors are the way they're supposed to be. We can't prove those factors, so we make a theory for each possible major arrangement of factors. The universe is either flat, hyperbolic, or spherical, although we can't completely properly visualise that because it's four-dimensional. If the universe is spherical and has no edge, light can probably circumnavigate it. If light can circumnavigate it, there's the that the known universe is smaller than the observable universe. There's also the possibility that it's bigger. Either way is a , and so we explain how each of those could work out.I never said any of the things I said were absolutely true. If I did then I was being dumb. [/quote] I literally just threw my phone into the ground (scaring my brother), because A) You can't claim that something [i]should[/i] be a certain way. B) There's not a single reason to believe that the universe is four dimensional, and you can't proclaim it as truth until you give some sort of evidence. I can draw the illusion of a zero, an actual one and two, or even the illusion of a three dimensional shape on a two dimensional surface. C) I'm not against discovery, but I'm against ignorant declaration of truth, or attempts to find the answers to questions while offering answers that can't be verified! We need the technology first, and to do that we must expand in other areas. D) I've read my brother this whole conversation and he says that the theories are unscientific.
