I hope you mean less than .1, i.e. closer to 0. The
p-value is the probability of observing the test statistic
you found in your data or an extremer test-statistic, given
that the null-hypothesis is true. If this probability is 
small, then we conclude that it is too unlikely that we got
the data we got by accident, so there must be something 
wrong with the null hypothesis, and we reject the 
null-hypothesis. So small p-value = reject = significant, 
large p-value = not reject = not significant.
