By that I mean is "empty" space actually made of some sort of "stuff" or is it just defined as the distance between other "stuff". I personally find it hard to believe it's not made of something - for the simple reasons that I can't really comprehend nothingness (a lack of anything at all implies non existence to me, and if you're looking at it how can you say it doesn't exist!) and also seeing as "empty" space can transmit force, carry light etc, it seems reasonable to expect that there must be some medium to physically enable the transmitting / carrying.

Sorry - I realise these are questions, not snippets of information!

I'm not sure I'm understanding your question correctly, but if I am, this has already been solved by Einstein. Yes, the "empty" space is made out of something, we call it space-time and Einstien calls its a "fabric" because it's malleable.


Einsteins General Theory of Relativity is all about Space-Time and how objects move and interact in it. When you accept that what you visually see as "empty" as you describe it, is an actual fabric that holds everything together, then it becomes more obvious why objects can orbit around each other.



It also explains why light bends around large objects like stars, because space-time itself bends.

I just about grasp the spacetime thing, as in the concept of space and time being intrinsically linked and how that gives rise to things like time dilation and so on, you can't move through one without effecting the other. So far, so clear as mud.

But I'm still a bit lost as to whether it is an actual physical thing, or it's just the nothing between physical things, kind of like the holes in a sieve say.

When the universe expands is it because more of this spacetime "stuff" has been physically created (in which case what is being made from?) or is it just that the other stuff has moved and the gaps between have gotten bigger?

I've a feeling I'm explaining this like a five year old coming back from anaesthetic!:D

This is the song he wrote about Trump.

Even asked to bite down on something like say if you were at the dentist getting a mouth guard fitted...well you can't bite down, only up, because of course it's your jaw that moves and your bottom teeth move with it. So you can't move your top teeth at all thus you can only bite up.

Is that just a hypothesis or is it a proven fact?

Where could it possibly be coming from? It's creation must require energy of some sort?

Proven fact.

Spacetime is capable of creating more of itself under the right conditions, it doesn't require energy.

Eg: you don't need to be great at maths to be an architect

this is obvious to me but everyone says to me "i wanted to be an architect but i was bad at math,i can barely add"

This is so true. The amount of times we receive a set of drawings and attempt to lay out walls/ceilings to find out that the architect has added up the room sizes incorrectly or didn't measure the actual floor area properly is unreal.

Absolutely. Yet the peanut, or ground nut, is still the seed of the fertilised flower that appears, as usual with plants, on stems of the plant above ground. The ovary is located at the base of what appears to be the flower stem but is actually an extremely elongated floral cup. After the flower is fertilised, a stalk at the base of the ovary lengthens to form a thread-like structure known as a page. The peg grows down into the soil, and the tip, which contains the ovary, develops into the peanut pod.

We always called them monkey nuts when they were in every kids pocket for weeks after Halloween. But in truth the only monkeys that eat peanuts are contained in zoos, as peanuts don't tend to grow where monkeys live.
