The Big Bang

Travel back in time to an era when the universe was young, very very young. Many exciting things will happen so fast that you won’t be able to observe then directly. You will need a very good tour guide to interpret what is happening right before you. Such interpretation sounds like the ranting of a lunatic, and is prone to change from visit to visit.

The observation platform is set well back from the action, because the expansion is so rapid and violent that the unsuspecting and unwary visitor is in grave danger. Be sure to stay well back, (We are well aware of the logical conundrum of a platform outside of the universe, but have chosen to ignore it). In just the first

0.00000000000000000000000000000000000000000001 of a second, big-E Everything will come into existence, and will occupy a space 0.0000000000000000000000000000000001 centimeters across. About 1 second later, the universe will be about a quadrillion kilometers across, give or take a few billion Km.

During this time, every proton, neutron and electron that will ever exist will come into being, even though it will be another 370,000 years or so until they cool down enough to form any actual objects. During this first second, the temperature of the universe will drop by 10²² degrees, an experience familiar to anybody who has been through a great-lakes springtime cold snap.

You would think that a burst of energy of this magnitude would also be bright. One of the most amazing things about the Big Bang is that it remains dark. Things are so dense at this point, that all light is immediately absorbed.

Armchair tourists who wish to observe the Big Bang from here and now are invited to tune their televisions to a channel that is nothing but static. A small percentage of that fuzz will be background radiation leftover from this truly cosmic event.
