Dolphins, whales, bats, and other animals are known for having a complex ability to emit sound in the darkness of the night or the black depths of the ocean, somehow illuminating that dakness. What does echo imaging of familiar objects look like?
In 2015 a group of researchers at SpeakDolphin.com attempted to construct an image of a diver, among other objects.
Just something to smile about...
Colony Book #4 is started! The first three chapters have been posted to the Work in Progress page.
Also in work is a short story for an anthology to be released sometime in 2019 tentatively titled Escape to the Moon. I’ll let you know when that becomes available!
Additionally, ‘Cradle of the Sun’ has been published in paperback format. You can get in at Amazon!
Happy New Year!
You may have read of heard about this stuff already. It's a spray-on plastic coating that lends a very impressive amount of strength to whatever it's sprayed on.
Aerogel is an amazing material. You can purchase samples of it online for a reasonable price. In compression, it is about as strong as tightly packed sand. When they say it reacts poorly to moisture they aren't kidding - it will melt as you breathe on it, or leave behind a fingerprint from the moisture in your fingers. I showed the sample I purchased to the kids and within a minute of experimenting there was nothing left.
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.
A superconductor is interesting because it also has a property of providing perfect insulation from a magnetic field.
Add to things that seemed impossible. Graphite and individual platinum atoms have been observed in time lapse and at different angles.
