As usual, Harry is ignoring all the evidence that is less than convenient for his cause. See previous posts in this thread by ckam - time dilation has been measured, and conforms to the expectations of SR within the limits of experimental error (and necessary corrections for GR effects). Also, if yo...

Hello All Wadsworth said what makes the rate of decay decrease as speed/motion increase!? Does it? Gawd Harry! The experiments that prove this are too mumerous to mention. They involve things like cosmic ray obsevations, synchronised (atomic) clocks, even the corrections required for the GPS system...

Re: A General Question
See this threadNeoEspiritus wrote:Why is is that we can get crystal-clear images of galaxies millions of light-years away and nebulae hundreds of light years away, but all the images of something a couple hundred million miles away come back looking like sonogram pictures?

The bit about spaghettification is not necessarily correct either. Spaghettification is a result of the force of Gravity being stronger at you toes than your head (your toes are closer the the centre of the Earth - or the black hole). If the black hole is sufficiently large, this difference is negli...

To suggest that the universe has a shape implies that it has boundaries/limitations. This, in turn, implies that there exists something beyond the shape that “it” is not part of :!: Er - no. This is difficult to discuss because it is outside our normal perceptions, and our vocabulary cannot cope wi...

If the universe is expanding like a balloon; we should still be able to see beyond that with good enough telescopes. I don't see why not. :? My post was very poorly written. Sorry about that.

Thanks for your input astro_uk. I wish the JWST was now. If there was a BB; we should be able to see the edge of our universe. You're assuming the universe has an edge. That would be true if it was shaped like an expanding sphere (3D object). However, if it is shaped more like the expanindg skin of...

..how?
I see impact events that happen to be separated in time, but not in space.

But how would you explain it if you didn't know about relativity? How could Newton have explained it? and later But I don't think we can make an argument about it using relativity-talk. This is more of an historical question. You don't need to invoke relativity to get an (albeit incorrect) explanat...

Theories have been proven wrong (including Harry's, he just doesn't know it yet)... I've been trying to figure Harry out - and can't. He doesn't seem to have a religious agenda, so I'm inclined to think that he tries to understand the information presented using an intuitive or common sense approac...

It is unnerving just how many pass so close to earth! (though, they cant be *that* close because i notice their paths of travel are not visibly altered by Earth's gravity) Not close at all. The scale is such that there is a noticeable curve in the Earth's orbit. [Opinion-guess]At this scale the Ear...
