Falsifying a young Universe. (re: Supernova 1987A)

Hi time.You should be aware that regular contributors to this site number amongst them some highly qualified biologists, physicists, geologists and scientists of many other stripes. Son Goku is one of them.When you ask questions like "Do you know what time is even?", the chances are that they know far more than you thought possible.They are also very kind and patient with their help and explanations to people like me, who want to try to learn. If you engage with that in mind, there's a great deal to learn here.

It boils down to this. When we see things moving from one place to another here, we observe that time passes to allow the change in the spatial coordinates of the objects.When we observe distant planets move around distant stars, the best understanding we have is that time is passing there also. Because that's the best understanding we have here, and nothing we observe operates to invalidate that.If you want to dislodge that understanding, you have to propose an explanation as to how things move without time passing. And then we have to test that explanation. If the explanation holds predictive and evidential water, you score !Simply saying "you don't know" is childish prattle, however. It's functionally no different to saying "pink fairies in tutus could be magicking the movement, whilst simultaneously drinking time through furry straws". Until you show us some awesome pink fairies in tutus, you're just doing what my children used to do, sticking your fingers in your ears and repeating "nuh nuh nuh nuh".

Hi mate - quick question, but only if you have time. (Tangential to the topic, but connected, I guess).Do I recall you or Cavediver once explaining (using the analogy of a meter ruler, touching the table at one end, and moving in an arc from perpendicular to flat), that everything is moving at the speed of light, as a combination of temporal and spatial velocities ?Hence the faster you move spatially, the slower time (from your frame of reference) passes. So for a photon, travelling spatially at the speed of light from the sun to earth, from its perspective, no time passes. (Though of course, from the perspective of the observer on earth, 8 minutes or so passes).And that this is an illustration of how, if one twin popped into a spaceship and zoomed around in space for a while, she'd come back younger than her twin.Edited by vimesey, : Typo

I have some reading to do ! :-)(Which from me, means thank you mate) :-)

How will we know that there is a genuine period of self-suspension though, if we don't know that time is passing where you are ?
