if there are billions & billions of galaxies and stars, why is the space so empty where if you are inserted into space in random, the chances that you might find a galaxy is 10 to the power of 33.

are we the end of line in evolution? does nature has another ace up its sleeve, a better one? have we interfered with nature to such an extent to have confused it? looks like it has to clean the slate to write something else.

In quantum physics, the Heisenberg uncertainty principle is a mathematical limit on the accuracy with which it is possible to measure everything there is to know about a physical system. In its simplest form, it applies to the position and momentum of a single particle, and implies that if we continue increasing the accuracy with which one of these is measured, there will come a point at which the other must be measured with less accuracy. Mathematically, if Δx and Δp are the uncertainties in the measurements of the position and momentum, then the product ΔxΔp is at least on the order of Planck's constant. Stated with more mathematical rigor, the uncertainty principle states that when measuring conjugate quantities, the product of their standard deviations must be at least h/2pi.

How are they formed? Are they from one specific plant or are they clumps of random twigs and branches or are they something completely different?
