Going to Mars won't save humanity, but working out how to live away from Earth could, even if that means learning on Mars how to live under the Earth to survive the 1450's imps, 1950's Apocalypse Godzillas and 2010's Biotech Zombies...

If the emoji are standardized in Unicode, then it will be easier for any kind of software to support them.

Why don't they get honest and say "Smelting aluminium at 960 degrees".

Look at Safety Advantage #11 Destruction of existing long lived wastes in LFTR What is wrong with my periodic table?

exactly, burn it all in the Thorium reactors to come.

NASA is focusing on research and new tech as it should and Starshade is an excellent example.
NASA shouldn't do an orbital shipyard and asteroid hauling - that is engineering - let SpaceX and Google do that in private enterprise.

it's no parlour trick. For tasks like navigating down through an xml file, parsing boolean phrases like "a and (c or (d xor e)))", searching a folder system, navigating a tree, implementing Qucksort Algorithm, Towers of Hanoi, giving change with coins, etc have NO STACK OVERFLOW issues
Show me smarter ways of solving these problems.
A while loop can have a stack overflow if you forget to increment a counter. That's just bad programming - it doesn't mean a while loop is bad.

In the last 16 months I ran workshops around the world for over 200 technical consultants working for IT companies. Less than 10 of them would be able to write recursive or sort functions or other problem-solving algorithms. Most of them were what I call "configurers". A massive amount of the problem-solving burden falls on me because i learnt how to program in the 1980's before the internet and code libraries appeared.

You might be carrying 5 very rare genes that now have GPS coordinates of origin - this could tell you all of your origins.
And even in the very mountainous Dolomites of Northern Italy they demonstrated that Ötzi (4000+ years old) has almost the same DNA as the people living there TODAY. Some some genes can stay in the same spot for a VERY long time.

Energy and matter have intrinsic value. If I had at my disposal 65 TJ of energy that is very valuable - in anyone's eyes.

Your question is whether Dark Matter could be real and observed MACHOs.
The other main option is that Dark Matter could be hypothetical WIMPs
Numerous experiments have ruled out MACHOS as making up the bulk of Dark Matter. The missing mass problem is not solved by MACHOs.
At the moment the WIMPS are beating the MACHOS.

A planet that is ejected from a star is called a Rogue Planet and just orbits the galaxy itself.

Facebook knows who your family is, where you work, who your kids are and all of their friends and teachers and everybody else you have known for the last 20 years, because they all gave Facebook and Whats App access to their entire address book. It simply doesn't matter what you did - each of your email addresses is a GUID point to you.

15 years ago they were grumbling these kids couldn't run nor catch a ball. Horrors, what will they be saying in 2025?

I just want to see the Falcon land!!!
