Everybody knows whats a worm hole, does anybody know how can it be started and is it practical in today's science? Are we assuming that our universe is curved in space (if worm hole is a short cut)? Doesnt gravity bend space?

hi

see http://www.mcs.vuw.ac.nz/~visser/030527-12.html first

It is unknown whether (Lorentzian) wormholes are possible or not within the framework of general relativity. Most known solutions of general relativity which allow for wormholes require the existence of exotic matter, a theoretical substance which has negative energy density. However, it has not been mathematically proven that this is an absolute requirement for wormholes, nor has it been established that exotic matter cannot exist.

Recently Amos Ori envisioned a wormhole which allowed time travel, did not require any exotic matter, and satisfied the weak, dominant, and strong energy conditions [5]. Since there is no established theory of quantum gravity, it is impossible to say with any certainty whether wormholes are possible or not within that theoretical framework.

Worm hole In space is yet a theory without proof.
But I can tell you how to start a worm hole in the ground if you wish, see you take a worm...

The presence of a wormhole has not been found yet. But theoritical physics state that negative masses can open an wormhole. It can also keep it remain open for a long time. But, we donot know whether negative mass really exists.

1) Use an atom smasher (might be created in a few years) to smash an atom an create a black hole.
2) Buy earthworms to put them in your garden for a few days.

1)Collapse two stars with cores of at least 4 solar masses each.Bind them to each other with a superstring.
2)No
3)Yes
4)Yes , thats why you need the superstring :)

Plainly speaking, you don't and we just don't know yet
