It would be the equivalent of taking a pea and expanding it to the size of our solar system in a time less than a millionth of a blink of an eye.
If this occurred, it would mathematically allow for the uniformity of the [[CMBR]] - the vast distances were in thermodynamical contact before the rapid inflation.<ref>Castelvecchi, Davide, [http://www.symmetrymagazine.org/cms/?pid=1000045 The Growth of Inflation] ''Symmetry'', 1(2), December 2004, p.12-17</ref><ref>Hinshaw, Gary, [http://physicsworld.com/cws/article/print/24768 WMAP data put cosmic inflation to the test], 3rd May, 2006 (PhysicsWorld.com).</ref>
However, no naturalistic mechanism that would cause this sudden expansion is known, and inflation remains, at present, entirely speculative. An implication of inflation is that inflation may have acted not only upon the galaxies themselves, but also upon the light that was emitted by them, which would mean that the light reaches Earth much quicker than the speed of light alone would allow, so that the universe is much younger than it appears to be.
