    Telepathy is now possible.

    From India all the way to France.

    Pity they're still so comparatively expensive, but a great development nonetheless.
    Which 50%?

    The good 50%.

    Its randomised, which is why siblings will have different genomes. The exception being identical twins, who come a single egg/sperm combination.

    Cake, and grief counseling, will be available at the conclusion of the test

    Speaking of reproduction..

    Some species reproduce asexually via a process known as parthenogenesis.

    This basically means that they can induce the development of an egg into a embryo without fertilisation.

    At the genetic level it is sort of like giving birth to a clone of yourself..

    And thanks to epigentics eg the effect of environment on out genes we can explain why some twins aren't identical.

    I overheard conversation between two men on a train once, one of them insisted his two children - boy/girl fraternal twins - were 'identical' twins. Some people really think it just means a close resemblance.

    Events in the future can affect what happened in the past.

    The double slit experiment, showed that light behaves as both a wave and a particle, odd enough, particularly when it is shown that observing it makes it one or the other. According to an experiment proposed by the physicist John Wheeler in 1978 and carried out by researchers in 2007, observing a particle now can change what happened to another one in the past.

    According to the double slit experiment, if you observe which of two slits light passes through, you force it to behave like a particle. If you don’t, and observe where it lands on a screen behind the slits, it behaves like a wave.But if you wait for it to pass through the slit, and then observe which way it came through, it will retroactively force it to have passed through one or the other. In other words, causality is working BACKWARDS the present is affecting the past.Of course in the lab this only has an effect over tiny fractions of a second. But John Wheeler suggested that light from distant stars that has bent around a gravitational well in between could be observed in the same way which could mean that observing something now and changing what happened thousands, or even millions, of years in the past.

    The Quantum world is ****ing amazing.

    Well non identical twins are from 2 separate fertilisation events, essential regular siblings who happen to share the womb at the same time.

    Identical siblings come from a single fertilisation event, that splits as a zygote (thus called monozygotic twins)

    Epigenetic does explain differnces in monozygotic twins, indeed these twins are used to study epigenetics, as it provides the opportunity to look at 2 identical genomes being expressed differently.

    Apparently if you were in space, travelling towards this view at the speed of light for the rest of your life it would look no different to the view you see now vs in 80 years time, i.e the difference would be too small to notice.

    The universe could be finite yet without boundary. Like the surface of a sphere only move everything up one dimension.

    Event A occurs before Event B for me.
    But depending on how a second person is travelling, Event B could well occur before Event A for them.

    Yeah there's a lot of interesting stuff like that but information can't be transmitted to the past as such if I'm not mistaken (as quantum effects are random).
    Still mind-boggling as you say.

    Well cytosine methylation patterns are one way to tell monozygotic twins apart.

    We are nothing but specks of dust lost within the sands of time. There's nothing like Space to make me contemplate the insignificance of the individual.

    Well on the inverse to that there's nothing like the quantum world of enzymes and proteins to make me feel significant. Life is chemically difficult to sustain yet here we are.

    This is more what science can't tell us.
    My perception of blue could well be very different to your perception of blue.
    You can extrapolate that beyond mere perception obviously.

    Crazy thought. For all I know everyone I know is just a well-behaved zombie.

    Science may never answer the question of what the subjective quality of a feeling/thought is.

    Basic one that might interest people is that before you decide to do something your brain has set the process of deciding in train. A sense of agency is largely an illusion that "we" are in control, not our brains. Consciousness is epiphenomenal in that sense.
    Crazy when you (er your brain i mean) thinks about it.
