Please consider supporting my work here at Behind the Black. I keep the website clean from pop-ups and annoying demands. Instead, I depend entirely on my readers to support me. Though this means I am sacrificing some income, it also means that I remain entirely independent from outside pressure. By depending solely on donations and subscriptions from my readers, no one can threaten me with censorship. You don't like what I write, you can simply go elsewhere.

 

You can support me either by giving a one-time contribution or a regular subscription. There are five ways of doing so:

 

1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.

 

2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
 

3. A Paypal Donation:

4. A Paypal subscription:


5. Donate by check, payable to Robert Zimmerman and mailed to

You can also support me by buying one of my books, as noted in the boxes interspersed throughout the webpage or shown in the menu above. And if you buy the books through the ebookit links, I get a larger cut and I get it sooner.


The darkest material ever made

Scientists have developed a material so dark it is difficult to discern the shape of any object it coats.

The material absorbs all but 0.035 per cent of light, a new world record, and is so dark the human eye struggles to discern its shape and dimension, giving the appearance of a black hole. Named Vantablack, or super black, it also conducts heat seven and half times more effectively than copper, and is ten times stronger than steel. It is created by Surrey NanoSystems using carbon nanotubes, which are 10,000 thinner than human hair and so miniscule that light cannot get in but can pass into the gaps in between.

The pictures at the website are especially amazing. They coated half of a sheet of aluminum foil with the material and then crinkled the foil. You can see the crinkles in the uncoated material, but the coated material just looks black.

This will be very useful for astronomical instruments, as well as many other technical applications. For example, if you coat the body of your telescope with this material it will help eliminate stray light, which means that you will increase the efficiency of your observations.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

    Finally. I can complete my cloak of invisibility!

    I wonder what kind of a radar signature this would leave if painted on aircraft, or if this would have any applications for stealth, sounds like an awesome new material.

  • Stephen Westland, professor of colour science and technology at Leeds University, told the paper: ‘These new materials, they are pretty much as black as we can get, almost as close to a black hole as we could imagine.’

    “There’s something about this that’s so black, it’s like how much more black could this be? And the answer is none. None more black.”

    I think that this black might go all the way to 11. ;-)

  • Lerland

    It would definitely make it easier for military and people on the ground who don’t want to be seen because it absorbs so much light.
