We can do it.
Edit: I'll be providing a sort of commentary here, keeping track of our progress:
Between Nov 2 @ 14:56 and Nov 7 @ 18:27 (pretty close to five days), we asked 29 new questions, putting our rate since the time of this challenge at 5.9 questions/day. At this speed, we should have ...
Laser propulsion is a form of beam-powered propulsion where the energy source is a remote (usually ground-based) laser system and separate from the reaction mass. This form of propulsion differs from a conventional chemical rocket where both energy and reaction mass come from the solid or liquid propellants carried on board the vehicle.
History
The basic concepts underlying laser propulsion were first developed by Eugene Sanger and the Hungarian physicist Georgii Marx, with practical schemes being developed by Arthur Kantrowitz and Wolfgang Moekel in the 1970s.

In molecular evolution, a haplogroup (from the , haploûs, "onefold, single, simple") is a group of similar haplotypes that share a common ancestor having the same single nucleotide polymorphism (SNP) mutation in all haplotypes. Because a haplogroup consists of similar haplotypes, it is possible to predict a haplogroup from haplotypes. An SNP test confirms a haplogroup. Haplogroups are assigned letters of the alphabet, and refinements consist of additional number and letter combinations, for example R1b1. Y-chromosome and mitochondrial DNA haplogroups have different haplogroup designatio...
The answer to this is surprising:
We are.
And many (if not all) other galaxies.
And they move faster than light.
See, the universe is expanding, at an accelerating rate. The fabric of spacetime itself stretches out, so that galaxies seem to move away from each other. The interesting thing is ...
