What is Hyper Space and Conventional Space?

Answer 1

The Sci-Fi idea of Hyperspace is a means to explain travelling vast distances in relatively short time. It takes a simple premise that Space & Time are not exactly seperate, but are different aspects of the same thing. Matter flows into it from the residue of the 'Big Bang' and the subsequent collapse of dying stars. The matter helps to shape the 'SpaceTime Continuum', thus expanding the visible universe.

But the physical universe (known as the 'Space-Time Continuum' to acknowledge that space and time are different aspects of the same thing) is not flat - it is curved, bowed, folded and wrinkled... caused by the gravitational effects of large objects and vast energy concentrations.

By creating a certain type of energy (by the carefully controlled application of anti-matter to matter) a field can be created that folds the SpaceTime Continuum around a given object (say, a 'star-ship') to a greater degree than that object's own gravitational power would normally allow. By then controlling the degree and direction of the 'warp' field the ship can move through the SpaceTime Continuum at apparent speeds greater than that of light. The ship momentarily breaks through the divides between the layers of the multiverse - an area called 'HyperSpace' as it is slightly to the left of our ordinary physical/visible universe - and slips between differing folds in SpaceTime until it reaches it's destination...

...whereupon the 'warp field' will be switched off and the ship will continue to travel in normal or 'conventional' space (so called because we all agree on what it is - it is what we see as the normal physical universe).

This is, of course, impossible. But if one wishes to see the delights of the universe on less than 10 Alterian Dollars a day, what choice does one have!

Answer 2

As the others said, scientifically there is no such thing as "hyperspace", it is an invention of science fiction. But it is similar to something that does exist. According to string theory (which is a conjeccture, not considered proven at all) the 3 dimensions we perceive are actually only part of a 10 (or 11) dimensional space. The other dimensions are either time dimensions or never expanded and so are too small to go through. These other dimensions could be considered hyperspace. If there were some way to go through them then it could be a shortcut, just like tunnelling through the earth is a shorter way to get from New York to Beijing than going around the outside.

Answer 3

Conventional space is all around you.

Hyperspace only exists in science fiction. Like the tooth fairy.

Answer 4

You can move your limbs in conventional space, move your mind in hyperspace.

There's very little air in hyperspace. I've found it hard to breathe every time I've been there.
