i fail to see how any of this is a counterpoint to my reply. neither relativity nor string theory are oven logic extrapolations. relativity is so completely different from anything else of its time that it's just mind-blowing, and string theory is simply weird.
they're the exact opposite of extrapolations. |
my statement
we may not be able to refer to time in the same reference as physical time in our universe, but mathematics allow us to extrapolate beyond that point in time of the big bang (call it nagtive time if you will). |
helios statement
yes, but that doesn't mean that the conclusions you draw from such a line of reasoning will have anything to do with reality. |
my statement
perhaps, but string theory models such a timeline outside of the realm of our universe. string theory may be almost purely based on mathematical theory right now but that was in a way true for einstein at one time: |
my counter to your point was that in einsteins time, black holes also did not have anything to with reality as he himself imagined.
so as gr was an exotic weird science back then and has now become far more excepted and even natural for sciencetist to think in, so too could it be of string theory in the future when some more direct or indirect evidence leads us to conclude the components of the predictions it now makes.
my motivation for the predictions of string theory
gr is used for predicting very large scale models while quantum mechanics is used for predicting very small scale models.
string theory is used for both.
so far string theory predicts the same results as gr and same results as quantum mechanics in both respective domains.
hence the results predicted by it, which both gr and qm cannot, might very well be true and people in the future may be able to observe some of this through indirect mechanisms.
currently scientist refer to dark matter and dark energy as "unknown elements" that they use in their current models to explain certain discrepancies.
if string theories predictions about a multi-verse is correct or has merit, then scientist in the future might be able to have better explainations for these "unkown elements",
ie - the existence of other universes might be the cause of these unknown effects we observe in our own (even though these universes may not be physically connected by space time, string theory predicts they are connected through the multi-verse via other dimensional "matter".
so whether or not string theories predictions of a multi-verse are true or not my real point is this:
string theory uses mathematics to extrapolate further as was the case when gr was invented.
mathematics is thus an underlying component by which we can "explore" our reasonable options better.
with mathematics we can define anything and build logically upon it - it just have to be useful to us.
if we conclude that the unverse just sprang into existence from the big bang with nothing else influencing it, then we are in the realm of meta physics.
thus it would be more logical to conclude that something must have started off the process (just like a program not knowing what exists outside of its environment, the reality still exists that someone has switched on the computer).
as pointed out above, we can use mathematics to define any system and build logically upon it.
however, the multi-verse theory would still beg another question:
what started the process of the multi-verse?
we can then use mathematics to yet again define something else that would explain what started off the multi-verse, but this would then lead to the next question ...
so we cannot with mathematics explain the ultimate question of what started it ALL.
