There's a recent post over on reddit's conspiracy sub, citing NASA on this claim. Utter junk, the sources are just no-name websites in circular references to each other.

The explanation makes zero sense, Jupiter and Venus will be within 1 degree of each other, one will be South West (in our sky presumably - hah), and Venus' brightness will cast a cloud of Hydrogen onto Jupiter or some such BS. I'm no astro-phycisist, but I can see this is complete bolocks.

It's more likely that this happens:

The central banks will be shut down by an omni-present computer virus, and we are left to fend for ourselves for 12 days and 12 nights, only to awaken from the current global human slave-race matrix, where off world technologies thousands of years old have been kept hidden from us, and will start to be disseminated to us. All we need to do is work on our spiritual aspects.
