    About 790,000 years ago, a meteor slammed into Earth with such force that the explosion blanketed about 10% of the planet with shiny black lumps of rocky debris. Known as tektites, these glassy blobs of melted terrestrial rock were strewn from Indochina to eastern Antarcticaand from the Indian Ocean to the western Pacific. For more than a century, scientists searched for evidence of the impact that created these pitted blobs.

  2. I agree completely, although there is some good quality channels on YouTube, if you don't understand the details and are just a layman it can be hard to tell if it's real or just a hypothesis. 

    But if you think their bad, you should see some of the stuff on Quora :lol:


  3. Iran plane crash. Experts doubt 'Technical failure'.

    Quote

    Doubts have been cast over Iranian claims that a plane crash near Tehran was the result of technical failures, with experts saying a "shootdown" was the most likely reason...."This is catastrophic and not the type of crash that comes from an engine failing...."It is very unusual, you would expect to see some wreckage but all we can see here is debris."

    What a wonderful start to the new year. A new war. 


  4. The brain has it's limitations just like everything else. But there impressive nonetheless. 

    Quote

    The human brain may be able to hold as much information in its memory as is contained on the entire Internet, new research suggests.

    Researchers discovered that, unlike a classical computer that codes information as 0s and 1s, a brain cell uses 26 different ways to code its "bits." They calculated that the brain could store 1 petabyte (or a quadrillion bytes) of information.

  5. Not sure if this will help you or not.

    Some of these are online and some are international, and they're expensive too.

    Edit- just read your OP title, 1-2 weeks. These will be useless then. Sorry. :wacko:

     

     


  6. A - Yes, it's called 'thinning', but it's controversial. Quick search found this from 2009.

    Quote- "Fire-science experts say that overgrown forests must be thinned. Environmentalists say that thinning is really an excuse to engage in destructive logging. And then everybody heads to court".

    https://www.csmonitor.com/Environment/Bright-Green/2009/0902/wildfires-the-causes-and-solutions

    B- I imagine this would require so much removal of forest when added up you'd run into the same problems as A.

     

     


  7. Not likely soon, but...

    New research has put forward another idea for what such a radical stellar engine might look like.

    Via this beautiful video via Kurgesagt you can learn all about the so-called Caplan Thruster, which would use the Sun's own energy to propel it across the galaxy and beyond. It's named after the scientist who came up with the design, astrophysicist Matthew Caplan from Illinois State University.
     

    ....The Caplan Thruster would sit close to the Sun, using electromagnetic fields to gather hydrogen and helium from the solar wind to use as fuel. That would power two jets of energy – one using helium, pushed through a fusion reactor to create a jet of radioactive oxygen that would move the Caplan Thruster forward, and one using hydrogen, to maintain distance from the Sun and to push it forward. The Caplan Thruster would essentially act as a kind of tugboat.

    The XENON1T detector has allowed scientists to observe an ultra-rare event: the radioactive decay of xenon-124.

     

    Quote

    In a subterranean laboratory, about a mile below Italy's Gran Sasso mountains, scientists are hunting for dark matter using an incredibly powerful detector full of liquid xenon. In their search for the elusive particle, they observed something else entirely.

    Their dark matter detector witnessed the rarest event ever recorded: the radioactive decay of xenon-124.

  9. Charles Darwin's work was based on observation and research over many years. 

    Quote

    Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species...

    His five-year voyage on HMS Beagle established him as an eminent geologist whose observations and theories supported Charles Lyell's conception of gradual geological change, and publication of his journal of the voyage made him famous as a popular author.[18]

     


  10. Let me get this right, You think nuclear and alien technology couldn't destroy a Pyramid? Why would aliens travel all this way and only bring one bomb :confused:

    And the reason people put themselves so deep into the soil is usually because they've died. So no need to worry about aliens or a nuclear attack. :-p

    1. Metametaphysics

      Metametaphysics is a branch of philosophy that explores the foundations of metaphysics. "Metaphysics is concerned with the foundations of reality. It asks questions about the nature of the world, such as: Aside from concrete objects, are there also abstract objects like numbers and properties? Does every event have a cause? What is the nature of possibility and necessity? When do several things make up a single bigger thing? Do the past and future exist? And so on. Metametaphysics is concerned with the foundations of metaphysics. It asks: Do the questions of metaphysics really have answers? If so, are these answers substantive or just a matter of how we use words? And what is the best procedure for arriving at them—common sense? Conceptual analysis? Or assessing competing hypotheses with quasi-scientific criteria?"

     


  12. U.K. police officers aren't above the law. Can't find a recent survey, I think they do them every five years. From 2015:-

    Quote

    A total of 1,629 police officers were arrested in the last five years for criminal offences which included assault, grievous bodily harm, and manslaughter, report the Sunday Times. Out of these, 500 were convicted of offences, or suspended from duty on suspicion of committing offences.

    Officers convicted of offences

    • PC Keith Wallis was jailed for 12 months for lying about witnessing an altercation in Downing Street involving the former Tory chief whip, Andrew Mitchell.
    • Osman Iqbal was given 7 years of jail time for prostitution, supplying a class-A drug, and money laundering in 2014.
    • Chris Higgs admitted to 16 crimes, including blackmail, fraud, perverting the court of justice, and witness interference, in March 2015.
    • Constable Trevor Jones jailed for 14 months after bombarding vulnerable women with sleazy text and voice messages in June 2015.

  13. Two heads better than one?

    They probably complimented each other, if it was engineering or something similar, then I can see why being around biology experts would give you an advantage over another lab which didn't.

    Edit- Misread the question, thought they were asking why? Oops.

    Edit 2- Have looked all over the internet (bing), can't find nothing.


  14. Top dark matter candidate loses ground to tiniest competitor.

    Quote

    Physicists have long searched for hypothesized dark matter particles called WIMPs. Now, focus may be shifting to the axion — an ultra-lightweight particle whose existence would solve two mysteries at once.

    IMG_2592.thumb.JPG.cb16c2eb22356ddbbf6d479f06192833.JPG

    The ADMX experiment at the University of Washington uses a strong magnetic field to search for hypothetical dark matter particles called axions.

    ADMX’s main magnet produces a field that’s about 150,000 times stronger than Earth’s. :)

    So the single engine 2WD has a claimed range of 500 miles and the 3 engine AWD has a claimed range of 250 miles.  Would the 3 engine version be the fastest or would the single engine beat it as it has to pull less weight (2 less engines)?

    From wiki :-

    Tesla Cybertruck model specifications[9]
    Model Range (EPA est.) 0–60 mph (0–97 km/h) Top Speed Payload Towing capacity Price (USD)
    Single Motor RWD ≥ 250 miles (400 km) < 6.5 seconds 110 mph (175 km/h) 3,500 lb (1,600 kg) ≥ 7,500 lb (3,400 kg) $39,900
    Dual Motor AWD ≥ 300 miles (480 km) < 4.5 seconds 120 mph (195 km/h) 3,500 lb (1,600 kg) ≥ 10,000 lb (4,550 kg) $49,900
    Tri Motor AWD ≥ 500 miles (800 km) < 2.9 seconds 130 mph (210 km/h)

     

     


  16. What do you think. Anybody thinking of buying one?

    IMG_2591.thumb.JPG.09b9b8c6a98bb922903a6e6fd8c342c7.JPG

    (From wiki) Tesla Cybertruck is an all-electric battery-powered light commercial vehicle in development by Tesla, Inc. Three models have been announced, with range estimates of 250–500 miles (400–800 km) and an estimated 0–60 mph time of 6.5–2.9 seconds, depending on the model.[9]

    I really like it, it's different. I love trucks, especially the Hilux, but I've got to say, if I had the money to buy one of them I'd definitely pick the Tesla. There's something about this that makes me want one. At least it's different. I'm not sure if it's futuristic or retro though, a bit of both really I think.

    Having said that, given a choice between the Cybertruck and this (below), I think I'd probably buy this. Ain't she a looker...

    Just an FYI, the OP of this thread has been identified as a spam bot. Feel free to continue discussion, but don’t expect them to contribute.

     

    Sorry for going off topic, but I'm confused, what type of spam is this? what's the purpose?. This is very high brow spam, I normally get sent click bait and funeral plans, crap like that.
