Popular Post octave Posted July 12, 2022 Popular Post Share Posted July 12, 2022 The first picture from the James Webb Space Telescope. This area of sky is the size that one grain of sand held at arms length would cover. This light began its journey 13 billion years ago which is stunning given the universe is only 13.7 billion years old. 3 1 2 Link to comment Share on other sites More sharing options...

Or the opposite. spacesailor I rather suspect, Spacey, that the Webb telescope is facing away from us. Otherwise the view might be spoilt by a rather big lump of rock. (Third rock from the sun) And by the glare from the sun coming around it. 2 1 Link to comment Share on other sites More sharing options...
Bruce Tuncks Posted July 13, 2022 Share Posted July 13, 2022 That picture shows the universe well before Earth formed. I think they would have been first generation stars. So their planets would have lacked elements that we require. Some of those first generation stars exploded in supernovas and this made the elements we need, so only second-generation stars would have had heavy elements in them and therefore their planets. The dust from supernovas would finally coalesce into second-generation stars. Link to comment Share on other sites More sharing options...

Yenn Posted July 13, 2022 Share Posted July 13, 2022 What happens when the telescope looks back and sees before the start? Will it just be black? Rather like looking back when you exceed the speed of light and can see yourself coming. 1 1 Link to comment Share on other sites More sharing options...

Bruce Tuncks Posted July 13, 2022 Share Posted July 13, 2022 You name it, some of our molecules once resided there... Hitler, Pharaohs, and yes T-rex. Maybe we should be buddhists, on account of how they preach of the interconnectedness of all life, which the buddha figured out without knowing about atoms. Darn, they believe in reincarnation, obviously nonsense... 1 1 Link to comment Share on other sites More sharing options...
nomadpete Posted July 13, 2022 Share Posted July 13, 2022 (edited) You can't quite say that your personal atoms have been in existence for 13.5 billion years. Because electricity moves electrons from atom to atom. So the atoms themselves are not made of the same bits that they got at the big bang. But our atomic makeup is basically that old. Further to that thought, our cellular makeup is constantly renewing itself and discarding old cells during our brief life. So, each morning we are not quite the same person that we were when we went to sleep. Cool, huh? Edited July 13, 2022 by nomadpete 2 1 Link to comment Share on other sites More sharing options...
facthunter Posted July 14, 2022 Share Posted July 14, 2022 Electrons (orbitting) have little mass compared with the Protons and neutrons in the nucleus. The only way to destroy mass is by nuclear reactions where energy replaces mass. E= MC squared. Some of the larger atoms are unstable and decay emitting rays.(radioactive).

Bruce Tuncks Posted July 14, 2022 Share Posted July 14, 2022 Yep, apparently we don't have molecules for more than 7 years. So you are certainly not the man you used to be...
