I think most people find this sort of thing interesting dont they? I don't pretend to understand it, in fact I find it totally mind boggling, compelling and fascinating. Try and get your head around this: ' All we have ever known, will ever know or could ever hope to know, would be exactly zero percent of the infinite cosmos'. youtu.be/_IkaetPoBZM

I havent got time to watch it, but i do take an interest in astronomy. I have a book on infinity which is probably out of date. In it 19th century mathematicians were abused and sacked from professorships for daring to say infinity exists.
Does the video say that infinity exists, no one knows. Certainly it seems like it. In the mid 90s i read in the paper that the rules of the Universe are universal, no pun intended, that the rules governing us, is the same everywhere, which i found astonishing, for some reason, unkown i presumed it would be different far far away.
This means that moons, earths, vast voids, packed stellar centres are everywhere. Mathematical measurements have been made, from one point to another over vast distances, that show no deviation or curve.
This means that there are no boundaries, or that the measurements arnt big enough. Certainly ancient galaxies have been found at the birth of the Universe, some stars are older indicating galaxies beyond our ability to see it.
Some astronomers suggest that boundaries may exist in the same way that water and ice exist, a fish cant swim in ice, but the rules remain the same.
If the Universe is boundless, then so are we, life forever. I dont think theres any dispute we exist, therefore nothingness cannot exist alongside existence, existence gives it meaning. Therefore, whatevers here has always been here, and always will.
Eternity has a downside, it would be like watching the same Star Trek episode forever. Its funny how we are born into this world with no memory of before, near death experiencers say we all drink from a river of forgetfullness, take that in the way you want, it is nescessary.
Imagine watching Star trek from the first episode, or saving private ryan, making love, eating crusty bread with milano salami, cheese and red wine, the birth of a child........for the first time. Life might be a way of passing eternity, and not going ga ga. Whoever the source is. There is one.

I watched the video in the OP last night, I often watch that sort of thing during the evening which is a reflection of the quality of TV programmes.
The video doesn't say the cosmos is, or isn't infinite. It asks the question. But it must be said, the inference suggests it is. But how do you measure infinity or time? The radius of the known or measurable cosmos is estimated to be 46 billion light years a distance which is in itself impossible for me to even begin to comprehend. But even so, that may be, is probably, an infinitesimally tiny percentage of what lies beyond.
As Leila Battison said; 'All we have ever known, will ever know or could ever hope to know, would be exactly zero percent of the infinite cosmos'.

Einstein's General Relativity requires a finite spherical universe, which does tend to beg the question, where it ends, what begins? Or maybe there's a picket fence.

One day someone will get to the edge of the Cosmos, litterally bump into it. They will open a door into another world and discover we are an experiment.

There different types levels of infinity
Your standard type of regular infinity is titchy compared to a really big infinity

If something exists it can't be infinite. The only "thing" that can be infinite is nothing. A finite universe can only perform a limited number of arrangements of its constituents and therefore must be repeating these sequences of arrangements. You have been reading this an infinite numbers of times in the past and will do so an infinite number of times in the future ... if the universe has always existed. The Greeks came up with this idea over 2,000 years ago.

Your brain exists or rather, the information in your brain must exist Is the universe large enough to create an information situation in which something thinks it is you, has all of your exact memories, has every impression it is you, but none of it is real because it is just a statistical consequence of infinity?
