Because of my leanings towards Electric Universe such anomalies (as seen here regarding background radiation) just reinforce my thinking. This is literal "information paradox" for this article will mean a totally differant thing to you than it does to me.
| Well, this article does not, by any stretch of the imagination, rule out the big bang theory; it is merely talking about inflation, and that there are some predictions of inflation that are now seen not to be only made by inflation. So, as the article says, inflation predicts gravitational radiation, but we know now that were we to detect some gravitational radiation it does not immediately mean that we have stone-cold proof for inflation, since other processes can cause gravitational radiation too. However, this does not mean that, even if we detect gravity waves, inflation is wrong. Quite that contrary; we can still use the amount of gravitational radiation (which is measured by some ratio called the "tensor to scalar fraction") to pick between the models of inflation one that predicts this certain value for the tensor-scalar fraction (since different models predict different values) but, as the article says, we are still in search for this "smoking gun" for inflation-- some prediction that, if observed, undoubtedly proves the veracity of inflation. ~neutralino If you haven't found something strange during the day, it hasn't been much of a day - John A.
