    Then why did Britain and the U.S. finance Hitler?  Answer .. to overthrow communism in Russia of course

    So? The question was why the reason for a war could be considered to be moral.

    s it possible to create a "superbrain" using modern or near future technology? Something that at least 10 times larger than human brain? Can we create a new race of conscious creatures in this way? Would they be thankful us for their creation? How can we make them good and morally perfect?

    We are limited because of the size off  our skull.

    A brain that's 10 times larger is rather heavy and then you need an elephant-like body to support it.

  3. It can change of course but in general, more people = more fossil fuel use, more cars, more food...

    The global population has grown from 1 billion in 1800 to 7.616 billion in 2018.

    They aren't the same thing, even if you find an occurrence where both things are happening at the same time. That's all it is — two things happening at the same time. 

    How do those photon detectors work?

    When you destroy a photon, doesn't conservation of energy states the energy is transformed?

    You can do the detection of which slit (using another, entangled, photon) after it has passed the slits. So you are not affecting the photon that went through the slits. 

    And what does “transforming its energy” mean? The photon that goes through the slits is not changed by the fact it’s entangled partner is observed.   

    When you detect a photon you destroy it and conservation of energy states the kinetic/potential energy of the photon transforms. When a photon is detected then you have imo, the photoelectric effect.

    None of that contradicts what I have said. 

    There are two things going on: you are collapsing the superposition, and you are destroying the photon. You can do either one, without doing the other. I can block one of the slits, so there is no longer a superposition, but not detect (and thus not destroy) the photon. I can detect (destroy) a photon that was not in a superposition.

     

    Yes but it's the observer effect like I said. Destroying a photon(also one that wasn't in superposition) implies transforming it's energy....

  6. Maybe the reason for a war can be considered to be 'moral' but in modern warfare numerous innocent people are generally killed because they happen to be in the wrong place. This is mostly because the weaponry  developed/evolved.  Wars used to be fought with sword/spear/bow and it was more about single combat.

    Weapons now kill a lot faster and can kill 'many' people at once.(Nuclear/biologic bomb….)

    The reason for a war can be considered moral but the war itself is not.

  7. When Europeans arrived in the Americas, they caused so much death and disease that it changed the global climate, a new study finds.

    European settlers killed 56 million indigenous people over about 100 years in South, Central and North America, causing large swaths of farmland to be abandoned and reforested, researchers at University College London, or UCL, estimate. The increase in trees and vegetation across an area the size of France resulted in a massive decrease in carbon dioxide (CO2) in the atmosphere, according to the study.

    Carbon levels changed enough to cool the Earth by 1610, researchers found. Columbus arrived in 1492,

    "CO2 and climate had been relatively stable until this point," said UCL Geography Professor Mark Maslin, one of the study's co-authors. "So, this is the first major change we see in the Earth's greenhouse gases."

    Before this study, some scientists had argued the temperature change in the 1600s, called the Little Ice Age, was caused only by natural forces.https://edition.cnn.com/2019/02/01/world/european-colonization-climate-change-trnd/index.html

    Did the Azolla event create significant hydrocarbon deposits in the Arctic?

    That's correct I think.

     As the Azolla fern sank to the stagnant sea floor, they were incorporated into the sediment; the resulting draw-down of carbon dioxide has been speculated to have helped transform the planet from a "greenhouse Earth" state, hot enough for turtles and palm trees to prosper at the poles, to the icehouse Earth it has been since.https://en.wikipedia.org/wiki/Azolla_event

    No, it's not.

    The observer effect can happen to systems that are not in superposition (it's not even required that the experiment be probing QM). Thus, they cannot be the same. The loss of  interference in a double slit can be from the observer effect (e.g. which-path information), but they are not synonymous. You can get which-path information without detection.

    Yes but in here they do use detectors and it is about collapsing superposition. When you detect a photon you transform it's energy. Observing a photon changes the photon.

    where is jesus and allah to help people that had great life and then were attacked or their life was destroyed by terrorist attacks etc. (just example). I dont feel sorry for the people. I think its wrong but I ask to understand the religion.

    It's about having faith. Many people do believe Jesus helps them and  and wil appear in human form to beam them up to heaven.

    I once got a ride of 2 Christian missionaries and I got the funny advice to restore my faith or Jesus would leave me behind. :)

    The study, published today in the journal Nature Communications, uses radiocarbon dating to determine the ages of plants collected at the edges of 30 ice caps on Baffin Island, west of Greenland. The island has experienced significant summertime warming in recent decades.

    When I did dogsledding, one of my dogs was called 'Baffin'. :) 

    I'm very curious to how nature will react. Trees and plants can grow bigger/increase in quantity and populate new area's...but plant eating insects as well.

    Like the Mountain Pine Beetle in B.C. .https://www2.gov.bc.ca/gov/content/industry/forestry/managing-our-forest-resources/forest-health/forest-pests/bark-beetles/mountain-pine-beetle

    To do that requires creating a quantum theory of gravity (that can be tested). That is the hard part. The question was: why is that hard.

    It's hard because only our  logic/intuition tells us it's there, it's a mental construct. 

    Gravity is also hard to quantize but that interacts with for example photons so logic dictates there is something physical about gravity.

    Can somebody share an a articles or something related with this topic. I want to understand well the main problem (the root and the details) and why it is so difficult. I've come across many videos and news that give you some kind of metaphorical picture (made for the public), which in some cases is quite misleading. I don't need the approaches (string theory, loop quantum gravity), i need just the problem!

    Thank you for your time!

    This is my oversimplified view/explanation. Spacetime is basically the medium in which quantizable observations do there thing. Spacetime implies a coordinate system to which we attach observations and try to understand/make sense of reality. I  think a quantum gravity model needs to be 'proven' and find its way in the world of  science/technology in order to quantize spacetime.

    Can children inherit something caused by outside causes. Something that their parents got during their life? Like HIV, losing hearing, something broken...

    There might be some mechanism since it can in some cases significantly increase survivability/adaptability. This is for wild animals, not for modern humans.
