It now seems that a small percentage of the UEF affected by interaction with matter will spiral preferentially through surrounding material - if that has the right atomic structure and spacing. We call such material 'magnetic'. And that 'spiral' UEF travels through a magnet from 'South' to 'North' - therefore the magnet's N pole is at slightly lower UEF intensity. Known and forecast examples are crystals , astronauts , airline passengers . Whether that putative 'new' universe would be larger than a pin-head is open to argument, as is another important question.
Most scientists say that is only an unreal subjective perception.
No - they are wrong again. Animals with brains constructed like ours perceive time by a physical measurement of the rate of change of that parameter of space. It looks as if Penrose's microtubules are the right shape and size to do that measuring. So when 'nothing's happening' around us we feel the full impact of time passing because we can. The microtubules have nothing else to do but to measure time fully.
