Document Summary
Our radio energy outpot extends to 70 ly. If aliens are hostile they can destroy us (via robots or radio); come here to conquer earth. Time to alpha centauri system (4. 3 ly away) Hazards: radiation, loss of muscle tone, micrometeroids. Quantum theory suggests that tiny wormholes : might appear in quantum foam, constantly form and disappear, are too small to travel through. Alien civilization might locate/enlarge foam wormhole and use pressure to p(cid:396)odu(cid:272)e (cid:862)a(cid:374)tig(cid:396)a(cid:448)ity(cid:863) to keep (cid:449)o(cid:396)(cid:373)hole ope(cid:374) A worm whole takes us to another location in our galaxy or in our universe. Creating an einstein-rosen bridge takes us to another location in another parallel universe: except end up in one of those parallel universe. These are greater than 25x the mass of the sun. Minimum mass of a star= 0. 08x the mass of the sun (8% mass of the sun: stars range from 0. 08xmass of sun to 100x (average= 4 mo)
