A cosmic hall of mirrors? Maybe...

A cosmic hall of mirrors

Featu September 2005

Most astronomers think that the universe is infinite, but recent
measurements suggest that it could be finite and relatively small.
Indeed, as Jean-Pierre Luminet describes, we could be living in an
exotic universe shaped rather like a football

At a Glance: Cosmic topology

• There are three possibilities for the curvature of the universe: space
can be flat, spherical or hyperbolic
• The geometry of the universe depends on its curvature and also on its
topology, which governs the way space is connected and so determines if
it is finite or infinite
• Measurements of the cosmic microwave background constrain the
curvature of the universe and provide hints about its topology
• Recent data suggest that the universe might be multiply connected,
like the left- and right-hand sides of the screen in a computer game
• Since the early 1990s the number of cosmo-topologists around the world
has grown to more than 50

Old news for Darla already informed us long ago of the space fun
house mirrors.

carry on,

SCP If the macro realm(cosmic) has its mirror images,this is also
reality in the micro realm(quantum) Bert
