The kids just love it to hear a "granddad" explaining all these things in a comprehensible way, learning English at the same time. And we love it because we don't have to answer those questions anymore ourselves ... But from this video I'm afraid what they will especially remember is how (not) to throw balls into baskets ...

@Typho0n86 Or, was there big bang at all??  we could ask that first

[lucaslodovico]

I'm no physicist, so bare with me for a moment. He says that there isn't enough matter to completely fold the universe in itself, thus disproving that it has a finite size. But in these calculation, is he (or are physicists) computing the mass of dark matter?

[BarrackObamarama]

@Rizzy55 Absolutely. Most people treat Science like a Religion and completely rule out the possibility of anything involving religion being true despite the fact that - to be honest - we live in a much crazier Universe in FACT than anything in any religious text.

In science you can only go on the evidence you have at the time. Not alot stands the test of time but the beauty of science is that it evolves to become more correct.

There is no room in science for closed minded people.

[Rizzy55]

Its so great to see science minus the arrogance and bold proclamations of absolute truth with everything presented as undeniable fact.

You can tell this wasnt one of those nerds who had a grilled cheese sandwich mushed into his head during lunch in high school who is now trying to portray physics as the absolute pinnacle of all "Knowing". Sagan did enough damage to reason in that area when he decided science was his god.

@MaxFlared Yeah time is a concept, but it still exists, we have history to prove it. It makes things move, and how we relate to one another. I got no idea what ur meaning by the hologram statment but... things do exist wheather we are there or not to observe them. The holographic is just a theory that tryes to expalin why we cant see. The size of the universe is relevent, because if it is finite then time is finite, and vica-versa with infinite

[MaxFlared]

@Typho0n86from the things i researched and came upon i realized that time doesn't exist.time is just a figurative illusion in our mind to project the holograms that our consciousness is playing through this physical body. its like a tape rolling on projecting all the clips in a movie thats it but we see it as time. the size of universe also is irrelevant.the reason we can't answer it is probably because when we decided to choose this experience we just created the surroundings not the SIZE of it

[Typho0n86]

Hrmmm if the universe is infinite, then time must be infinite as well. So there was a before the big bang...?

[mersinlialico]

there are 7 firmaments of the universe and what we observe is only one of those firmaments or heavens

@TheLA384 I get it, you're very smart : )
