Faster than Light Travel with the Alcubierre Drive

This is a very nice introduction to what you might call a modern warp drive by the very person who came up with the idea.

Problems of energy have been mitigated by an idea of oscillating changes to space, which reduces the requirement to make a bigger change. The ability to create something resembling Alcubierre's field was described by NASA in Warp Field Mechanics 101 and Warp Field Mechanics 102

There are still some things that need to get discovered for this to work as a faster-than-light technology. it presupposes the truth of an idea proposed in Einstein's time by a man named Nathan Rosen, that the compression of space and time is a new dimension of space, and not just some characteristic of the existing 3+1 dimensions. If this extra physical dimension. This dimension must exist for wormholes and the Alcubierre as a faster-than-light device.

Even if this isn't a faster-than-light drive, it is a great way to reach high speeds without the harmful effects of acceleration on the crew.

Dwarf Planet Haumea

Haumea is another new dwarf planet. Named after the Hawaiian goddess of fertility, in keeping with the tradition of naming planets and moons after characters in mythology. Haumea has an unusual shape and two moons. 

Dwarf Planet Makemake and It’s Moon

A lot has changed since My Very Educated Mother Just Served Us Nine Pizzas (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto). Pluto was downgraded to a dwarf planet, and three other dwarf planets (all having moons themselves) have been added to the solar system.

Woodward / Mach Effect Reactionless Drives

This is really remarkable. Based on the principle of the Higgs field (that mass is not constant) what might seem like an impossible Rube-Goldberg machine is, in fact, a real possibility for thrust without the messy rocket exhaust. You can read Mr. Woodward's ideas in great detail in his book "Making Starships and Stargates" from Springer publishing.

The video below shows a scale model example of what is being talked about. If mass fluctuates, you can push in one direction when the mass is low (increasing velocity cheaply). Then the system can "relax" when mass is high (not decreasing velocity very much). A small net velocity remains. Repeat, slowly adding velocity by increments. 

Lenz Law

Conductors exposed to an approaching magnetic object naturally develop internal magnetic fields opposing that motion. Like a science-fiction force field that only applies to magic objects.

Some elements repel a magnetic field to some degree. The effect is very small, except for in superconductors which have the added property of perfectly expelling magnetic fields below a certain strength.

CVD Diamonds

This is fairly remarkable, given that as a child the formation theory for diamonds insisted extremely high temperatures and pressures.
