    If the remains of the star, "Cas A," is 11,000 light years away, how could it have exploded 300 years ago and be visible to us now?

    Considering the elasticity of matter at different scales, and the probability that the supernova's explosive shockwave epicenter would be centered in the star's core, the heaviest elements (at the center) would be propelled by the greatest force at the greatest accelerations. The heaviest elements would be thrust out to achieve the greatest velocities, thus the greatest distances over time. That might be an explanation.

    I love science and different things we don't know about yet :)

    Simple math: Cas A exploded 10,700 years prior and the light reached earth 300 years ago.

    Thanks to NASA SCIENCE in generell and for this exploring and amazing video in a special way. It´s fantastic .

    Right. BTW, Wikipedia claims that Cassiopeia A is 10,000 light-years away.

    anyone can edit wiki so you shouldn't use that as proof

    Go to ICR.org where they actually use data for science, and not teach theories as truth because it suits them.

    Nice video!
    This is an invitation to see an artist theory on the physics of light and time!
    This theory is based on two postulates
    1. Is that the quantum wave particle function Ψ represents the forward passage of time ∆E ∆t ≥ h/2π itself
    2. Is that Heisenberg’s Uncertainty Principle ∆×∆p×≥h/4π that is formed by the w- function is the same uncertainty we have with any future event that we can interact with turning the possible into the actual!

    they are blow appart but in a spherical shape it's just that it take billions of years to be totally tear appart from eatch other don't forget time go differently in space.

    1) Carl Sagan's words are not immortal. Sorry.
    2) There are not enough supernovas which have could produced that amount of heavy elements we can today observe
    3) Where are the other elements? You mentioned just a few, like Fe, Mg, Si, O, S, Ne, ... but there exist so much more.
    4) We are consciousness, not an epiphenomena of some chemical reactions.

    True. It just sounds more natural. Star stuff sounds like a 7 year old's explanation of it. lol

    By necessity, Wikipedia adopted a scientific approach, listing references, sources & citations. This allows its descriptions & claims to be challenged with evidence. Like science, its numbers might change as new evidence arrives. It's not flawless, but it's a decent starting point to research. I noticed this change about 3 or 4 years ago as an occasional editor. Wikipedia's reputation as a credible source has not yet caught up w/ the hyperbolic memories of it in its hip-shot days.

    Religion is a "belief system". And in science any belief without empirical evidence is to be discarded. If you question religion or religious doctrines, you commit "blasphemy". On the other hand, science fundamentally progresses through questioning itself and refining itself. So sooner or later, if you do science, you will have to face the contradictions.

    You couldn't have said that if you'd properly understood the video.

  • @emiliolocura2
    @emiliolocura2 12 років тому

    Yes, basically what I'm saying is that if you really read the bible, then you know there's a part where it says that god will not judge beleivers and disbeleivers equally, but that in the end, our place in the afterlife will be based more on our actions than on our beleifs.

    Lady you have no idea about the real version. you have all the valuable data but still coming up with mambo jumbo. when will NASA get real about science and space.

  • @emiliolocura2

    OVerreacting, but basically you are saying a life of crimes, sins and despair are forgiven just for saying "I beleive"....thats plain stupid

  • @emiliolocura2
    @emiliolocura2 12 років тому

    Well, then I guess it will be nice to see all war criminals in heaven while thinkers such as Aristotle and Plato burn in hell...your logic makes as much sense as trying to light a fire in the rain

  • @emiliolocura2

    I don't care about that, I care about the fact that you are saying that god doesn't give a shit wether you are a mass murderer or the guy who spent his life managing world peace, in the end it all comes to a phrase, and that opposes everything christianity (TRUE christianity) teachea.

    no part in the bible says that, nice try. There is no way to fit science into fairytales.

  • @emiliolocura2

    Which is the reason I consider your "for the beleiver in Christ all sins are forgiven as if they never happened" idea idiotic.

  • @emiliolocura2
    @emiliolocura2 12 років тому

    Fanatism to both extremes in harmful, doesn't the bible mention (overly simplified) that actions>beleifs.
