    Amazing, realy like to know if individual particles can have a halo of darkmatter like galáxies have? Or darkmatter can exist in the void between nucleos of an atom and the electrons? All the best

      There is no void between the nucleus and the electron according to quantum physics.

      @@nunomaroco583 It can come down to different interpretations and I'm no expert.
      The way I understand it is that everything falls under the "wave function of the universe"
      If you haven't already I'd recommend listening to Sean Carrol's "biggest ideas in the universe" playlist on his RUclips channel. He explains things far clearer and with a deeper understanding than I ever could.

      @@nunomaroco583 curiosity is great! I love three subjects I just wouldn't want to give any definitives in an online discussion as I'm sure to make mistakes.. Roger Penrose is a particular hero of mine! Sean Carroll is a proponent of the Many Worlds interpretation, which while mind boggling is probably the purest form of quantum mechanics as It takes the data at face value.

    Martin what is your scientific opinion on this - did men really go to the moon and back in 1969? To be honest I can't make my mind up on this one. It all comes down to science and logic I suppose. Did the required technology exist back then? How could humans survive the radiation and certain dangers outside the earths atmosphere? Surely some health impacts would have happened? And vacuum, pressure, gravity are other big concerns. And a perfectly clean tin-foil landing module? Absolutely no surface disturbance? I still can't decide myself but I'm hugely interested to hear your scientific opinions on the reality of this horrendously dangerous journey?

      @@KarpucMotoring we can't even get to the moon now with advanced technology. Artemis have been planning since 2017 and still only done unmanned test flights. There's no way man got there in 1969. Any modern astronaut being honest to themselves knows it's BS about the landing in 1969.

      Are you fucking kidding me? Seriously,you're just fucking with us right? First of all if you were actually giving a chance to ask this man a question this would be it? Aside from that do you wanna believe in something so badly that you really think mankind hasn't been to the moon? Wtf is wrong with you
