    Actually very few larger animals can do that. The water bear is a tiny organism, and certain frogs are a different example. But after that there are not a lot who are known to survive prolonged freezing time. 

    Is it known what damage the freezing water causes? Maybe there evolved/developed material of an organism that survives freezing damage….if proteins are elastic enough maybe they can survive it.

    They all apply, and are present even if there is no measurement.

    How are they present? hey don't have a physical presence.

    Physicists derive equations all the time. Bose and Einstein derived the physics of the condensate that bears their name 80 years before the experiment was done. 

    Yes but equations need to be experimentally 'proven' .

    "Lighting bolts sizzle over Johannesburg, South Africa."

    Thunderstorms can reach voltages ten times greater than those previously recorded, a new measurement suggests. Sunil Gupta at the Tata Institute of Fundamental Research in Mumbai, India, and his colleagues used an instrument called a muon telescope to measure storms’ electric potential — the voltage between the top and bottom of a thundercloud. Muon particles are generated when cosmic rays smash into Earth’s atmosphere. As muons cross a storm’s electric potential, they lose energy, which causes some of the particles to fall below a muon telescope’s detection threshold. A storm with a higher voltage causes each muon traversing it to experience a greater energy drop. This means that a telescope’s detector sees a lower rate of incoming muons when storm voltage is greater.

    Gupta’s team used the GRAPES-3 facility in Ooty, India, to record muons as they reached the ground during 184 thunderstorms. Using computer simulations, the researchers estimated that the electric potential of one storm in 2014 reached 1.3 billion volts, the largest value ever recorded.

    This observation might explain the flashes of highly energetic γ-ray radiation observed during storms; scientists have theorized that only extreme voltages can produce such flashes.https://www.nature.com/articles/d41586-019-00934-z

    agree with most of your comments, but "afterlife" isn't really what I wrote about.  My point was that if we are here now, why not again.  If physics can get us here this time, why not again?

    In the OP afterlife is mentioned.

    It seems extremely unlikely. The cosmological model for the observable universe from the earliest known periods through its subsequent large-scale   evolution is what formed this solar system. And one planet (Earth) in this solar system had the correct composition for abiogenesis which developed/evolved humans.  Our history is what forms us.

    In what way can all of this happen again?

    Afterlife?  The thing is, we're here now, and if it can happen once, it can happen again.  That, I believe, is the key to "afterlife" no matter if our "next" life happens a millisecond or 100 trillion years after this one.  I don't believe we can dispute the "if it happened once it can happen again" concept.

    When you lose a loved one then you miss him or her and want/wish to see him or her again. This is imo a main reason people believe in afterlife.

    I often want to believe in afterlife but from a scientific point of view there is no reason to believe in afterlife. We are one of the many animal species on Earth. From a biological point of view there is nothing special about us.

     

  6. An international research team, including a member of the Complexity Science Hub Vienna, investigated the role of "big gods" in the rise of complex large-scale societies. Big gods are defined as moralizing deities who punish ethical transgressions. Contrary to prevailing theories, the team found that beliefs in big gods are a consequence, not a cause, of the evolution of complex societies. The results are published in the current issue of the journal Nature.

  7. "The technique could help boys made infertile by cancer treatment to become fathers later in life. "

    A one-of-a-kind rhesus macaque named Grady is growing up under intense scrutiny at the Oregon National Primate Research Center in Beaverton. That’s because she has an unusual pedigree: researchers created her using sperm from tissue harvested from her father’s testicles when he was young, and then grafted onto his body as an adult. If all goes well with Grady, the technique might one day be used to restore fertility in boys who have received damaging cancer treatments.https://www.nature.com/articles/d41586-019-00938-9

  8. Existence of biological uncertainty principle implies that we can never find 'THE' measure for biological complexity.

    There are innumerable 'biological complexity measure's. While some patterns emerge from these attempts to represent biological complexity, a single measure to encompass the seemingly countless features of biological systems, still eludes the students of Biology. It is the pursuit of this paper to discuss the feasibility of finding one complete and objective measure for biological complexity.https://arxiv.org/pdf/0902.0490.pdf

    What do you think of this?

    It depends what kind of angel he was...his job.

    Well I'm sorry to learn of your difficulties.

    Is there any way we can help?

    Also perhaps we should continue this in another thread or PM since it is a bit off topic.

    Thx for that comment. I'm used to living like that and got all the help I needed.

     My favorite science book was my geology textbook from when I was a Student.

    We just need to stop using fossil fuel and plastic

    Also, we need to eat a lot less meat (mammals fart methane which is a strong greenhousegas) and stop cutting trees/plants. Trees and plants  absorb CO2 while growing and release it in the atmosphere when burned. Wood also releases NO2 which helps to form ozone(greenhousegas). I don't think wood is considered a fossil fuel.

    That gives hope that they will cease pollution before it's too late.

    I wonder if that's possible. Isn't the only solution to insert solar power in polluting cities? Smog lessens the efficiency of solar cells but I did read they are creating smog cannons to reduce smog...

    I wouldn't call them crises, but disasters. And IMO WW3 started in 2001. We call it the war on terror. It's global.

    How, do you think people will deal with those disasters? The only way of lessening/reversing global warming and  all related effects is by killing most people. Many countries have  more then enough firepower.https://en.wikipedia.org/wiki/List_of_states_with_nuclear_weapons Nature recovers pretty fast and when vegetation conquers most farmland/villages/cities a global cooling will  start, like what happened when Colonizers killed many/most native Americans.https://edition.cnn.com/2019/02/01/world/european-colonization-climate-change-trnd/index.html

    I hope people will help each other instead of killing each other.

    They simply had to hide in the past.. not revealing their true orientation to public, as it could lead them even to sentence to death.. Even in modern times, in Syria thousands of people were murdered recently accused to be homosexual.

    On the other hand, it was forbidden in the UK by the Victorians.

    It's one of those things that goes in and out 

    of fashion.

    There are many exceptions but it seems, on average people are more tolerant. Same sex marriage is on the rise...

    Not even talking books?

    It's possible but my hearing isn't 'perfect' and my level of concentration is rather low. It's often hard to pay attention while watching movies or tv-shows.

    On youtube there are many lectures and even talking science books. A while back I started "Black Hole War: My Battle with Stephen Hawking to Make the World Safe for Quantum Mechanics" but did not continue.
