Does Space Need to Be Filled for Distance to Exist Between Two Objects?

AI Thread Summary
Space does not need to be filled for distance to exist between two objects, as it is defined by the absence of matter. The concept of space is inherently about emptiness rather than requiring physical substance. Removing everything between two planets would not necessarily cause them to touch, as distance is a relational property. The discussion touches on complex ideas like virtual particles and zero point energy, but these are not essential to the core question. Ultimately, the nature of space challenges the notion that it must be filled to maintain distance.

Something i need an awnser to! Its not homework just somehtign that has keeped me form sleeping for awhile.

But here's my view on it:

Space would need to be filled, so it can have a property fo distance bettween two thigns. Like if you had two planets netx to each other and youy take everyhting in the middle out so there is nothign doesn't that eman the two planets should be together toughing not apart?

Can soemone help me on this please? thanks.

Welcome to PF, Nick.
There really is no easy answer to your question. Space is not a thing... it's a lack of things. It doesn't need to be filled with anything, because its very nature is to not be filled with anything. When you get into virtual particles, zero point energy, etc., that's a whole different scene which I am not qualified to comment upon.
 
Thankyou! :eek:
 
You have a strange way of asking questions! Your question, in the title of this thread, is "Does space need to be filled?" but the main sentence in your post is the bald assertion "Space would need to be filled". If you believe that, why ask, and what evidence do you have that this is true?

Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.
Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.
