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.
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.

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.
of course matter can pop out of nowhere - it happens all the time, see Virtual Particle. What is different here is the vast scale at which it happened, and where this phenomon applies to the origin of the Big Bang
Don't throw away a theory because you don't understand how it is started. The Big Bang Theory is simply stunning in it's ability to explain almost everything in the know universe that we observe. It is up to someone else to work out what may have triggered it.
This is just like Evolution which brilliantly explains almost everything we see in terms of life as it is. but evolution is not Abiogensis
When you understand that Evolution and Abogenesis are different things, as are sex and embryology, you will also understand how you mixed up the Big Bang Theory with another area of study which is about multiverses, unverse bubbles, oscillating universes, God's Poke, and other interesting ideas that are today all still in the realm of speculation - because we have no way yet of seeing which of them could be true.
Big Bang cosmologists work on what is observable and testable and predictable.
Big Bang cosmologists are not expecting to find out how to create a big bang, but describe what happens after it occurs.

There is nothing wrong with "5 volt power transfer".
It is just saying that the power (whether 100mA or 100A) is always transferred at 5 volts, and not at 0.5 V or 50V.
What is strange here is the "power transfer rate". Power= "energy transfer rate". "Power change rate" would make sense when talking about power ramp up, (i.e. how many milliseconds it needs to go from 100mA to 1A).
A Type-C cable with100W racing through it sounds like a fire hazard to me.
The difference is that a taxi driver paid 30,000€ or more for his taxi license, and you paid nothing for yours. That's why they have this protectionist racket, because they are protecting their "investments".
Why is this going to landfill - how backward is that? Who does landfill anymore? That stuff is full of oils and proteins. It could be turned into biodiesel or put into a furnace to generate heat and electricity.
My company has employees in over 40 countries globally - 100 of us need to daily collaborate to build demo, download and upload virtual machines. A cloud provider gives us that for about 100,000k€/year and gives us servers in US, Europe and Asia. There is no way we could do that internally for 2 or 3 times that price. Cloud is a great solution for us - data loss, hacking, snooping etc are not issues because these are customer facing demo machines, and we download what we want.
I also use keypass+dropbox+iphone+Minikeepass.
Why is a keyfile an excellent option? If you only have 500,000 files on your computer (I bet you have less on your iphone), it can't take long to try them all - that is less secure than a 6 digit PIN, isn't it?
Or do you mean keyfile+passphrase? But isn't the effort to find the path of the keyfile more clicking/typing than an extra 6 digits??
Here is a beautiful interactive 3D simulation of how Rosetta got to where it is now. Where is Rosetta?. Video
The choreography of the Earth, Mars, Earth, Earth slingshots is just amazing.
Here is the complex orbits to come of Rosetta around the comet Orbit around Comet
Is there a genuinely secure mechanism for an app to store a password internally? I imagine they mostly just store an encrypted version of the password using a standard algorithm with an fixed "unknown" key/salt in the code. Isn't this just an example of security through obscurity?
This speed is still very fast if it is taken relative to us or to the galactic center. The galaxy's speed relative to the cluster plays no role at these sizes and time scales.
"sitting idle-ish and the galaxy zipping past" is the classic Relativity - it makes no difference - both are identical. In either case something caused that Star's velocity relative to us to by very different.
go and look at Ozone depletion and see that the alarmism was worth it because the world did ban CFCs and the charts show the improvement since. What we need is global coordinated action on the issues of today
Icebreakers being stuck in ice doesn't say much about climate change - incidents of such icebreakers stuck in ice over many decades may say something. Don't confuse an incident with a trend
I am sure there are many stupid Americans in New England seeing how amazingly cold it is this week and mocking Climate Change. (I live in Central Europe and we have at the moment one of the hottest Januaries on record). Climate Change predicts weather extremes because there is more energy available in weather systems to push to hotter and colder extremes.
That thick ice in Antarctica could be an example of climate change if, for example, more ice is rolling off the land faster, or climate change has changed currents to push more ice into that bay. Only objective longterm observations can help here.
There are problems with Alarmism, but it was right with Acid Rain in the 1970s, leaded petrol and Ozone in the 80's - those problems were reversed - and the scientific community is in consensus that CO2 today is a far more serious issue and we need alarmism before we reach tipping points.
I would rather take action with alarmism, then do nothing out of cynicism while species go extinct and Africans and Bangladeshis try to emigrate in their millions.

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

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

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!!!

The Malaysian government made the statement based on Inmarsat calculations, not on debris.

Calculus is summing lots of tiny inputs and making an output. Neurons sum a lot of tiny inputs and make an output.
Because your eyes are left and right of each other. Tilt your head 90 and try again.

That's what we said in the early 1990's when people were talking into mobile phones. Times change.
You are talking like a horse lover from the end of the 19th century who looked at cars and said "it'll never work - you cannot feed it".

You sound like the people in my grandmother's village in 1905 when the first car drove in - "It won't last - you can't feed it like you can a horse".
