This thread is for debate and discussion about the nature of the universe.

I will start with mine

The universe is INFINITE.
Infinite levels of both macro and micro cosmic substructure.
There was no beginning and there will be no end.
Matter does not exist. Energy does not exist. It is all the same depending on the observer's point of view.
Imagine someone went on a journey into the microcosm or macrocosm, taking with them a telescope and a microscope.
What would the universe look like to them after looking through each instrument?
I believe it would look the same at ALL levels of the infinite substructure.
Time does not exist. The only effect that space can have on time, is in a human head.
Time travel is science fiction and impossible.
If a human being wanted to travel "back to the 1920's", they would need to manipulate every single particle on every single level of the universe and arrange them in precisely the same way as they were at that "moment in time".
There is no empty space in the universe. EVERYTHING is connected.
The speed of light is not constant and neither is it the speed limit of the universe.
Why? Because the speed of light is different depending on the medium in which it is travelling, same as anything. There is no such thing as a vacuum, because there is no such thing a empty space.
If you were to go on another journey into the macrocosm or microcosm and observed a beam of light going through a galaxy, how fast is it going?
speed of light IS relative.

If thinking about the universe interests you too, please contribute your thoughts and ideas.
