  1. love the animation at the start. specially between 0:16 and 0:21 That's a computer generated model of an actual system that's being watched right now. HD 163296 is the star where three "baby" planets are currently being formed. Then there's PDS 70 with it's newly formed planet PDS 70b

  2. In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.

  3. Whatever man thinks and arrived from science and technology
    He can not reach the greatness of the Creator in the universe
    Look at these heavens and hope how God raised them by baptism
    And see how God created the earth and make its location balanced in a certain place to come close to burn the people of the earth even if it moved to freeze the people of the earth all this leads us to a fraction of the greatness of God and leads us to think in the Koran

  4. Very simple and elegant. I suppose I hoped for more detail but this is a YouTube video likely made to capture audiences who aren't already scientifically literate. It points out the basics and shows it off with some really cool animations; capturing the imagination if nothing else. Good work

  5. Theory at best because our science is not absolute to know everything? Now if human beings that can be immortal and with scientific instruments of advance technology able to witness and study such an event then there you have it to know and collected data to make it so?

  6. I have a theory that planets are actually alive. They speak in vibrations like Mars for an example, it's constantly making vibrations meaning a voice. If we could translate it..we could probably know what a planet is saying.

    Just a theory. Man can think you know

  7. Love you NASA and hope you do more exploring for other Universes
    and other in the galaxies and planets in the Universe and if you find other Universes
    Also please NASA find more Earth like planets and other planets that we can live on like Earth please NASA 🇺🇸🚀

  8. Could anyone imagine the benefits of colonizing Mars? There are untapped minerals and resources there that could shoot our economy through the roof. Not to mention starting a civilization there, which would eliminate a overpopulation crisis. NASA, you should totally get more funding!

  9. Wonderful video NASA!!! What you do is by far one of the most important things for the progression of humanity. Thank you for your hard work & dedication!
