That's ok Wallace. No offense taken. If I have misunderstood the expanding of the universe completely, can you tell me where exactly I can find a good explanation? You say the problem I was trying to solve does not exist, but that's not what the scientist that are studying the expansion say. But...

Hi, In this other thread https://www.physicsforums.com/showthread.php?t=354424" I was hoping to get a scientific answer to my question. Apparently this was not an easy question or hypothesis that was easily falsified. I was sorry to see the subject turned into a unpleasant debate which ended up...

Thanks heldervelez, you know a lot more a bout this subject. Do you think there would be a possibility to put this theory to the test? That's what I'm hoping for but I just don't have enough knowledge in this field.

Thanks for the link. There's a lot of information there, a bit too much for for to grasp at once :) I will think this over some more and will see where it gets me. Now back to the usual weekend-things to do. Thanks all for taking the time and sharing the knowledge!

So you're also saying the size of atoms is not related to the size/density of space itself? How would one determine this?

Yes, that's another way of putting it. But I'm not stating the actual size of the universe is static. I'm leaving this open because it could also be a combination of an expanding (or maybe even contracting) universe and contracting galaxies. I guess this would be very difficult to know for sure.

Isn't that what I pointed out with the image? In this situation your line would only look straight from the outside, but actually it's the line that's hyperbolic/curved relative to the space. Since you're traveling in this space - and not another dimension outside this space - traveling along...

Yes, you're right; there are no silly questions, just the silly people who ask them :) I need to learn more about all this for sure, but knowing all is a long way to go. Hubble's law may seem straight forward and proven. I still question it because it is based on the red shift which depends on a...

I guess you're describing a straight line through curved space like in this image? Although this grid/space is curved, the rectangles are still rectangles (correct me if I'm wrong). The line is not passing straight through the rectangles, which means the distance is actually longer going this...

Thanks S. Vasojevic. But I must tell I was actually expecting to get an answer like this. It leaves me with some other questions: 1. "universe must expand or contract". Isn't this only based on the "big bang" model, which is only a theory? In this model it does make sense, but what if this...

Hi all, I was watching some online video lectures from the Quantum to Cosmos festival, where they discussed the expansion of the universe and the problems this brings in physics. Problems like the need of dark matter and what the mysterious force is that accelerates this expansion. I've been...
