===Wormholes===
If [[wormhole]]s are possible, then ordinary subluminal methods of communication could be sent through them to achieve effectively superluminal transmission speeds across non-local regions of spacetime.<ref>{{Cite web |last=Morris |first=Brandon Q. |date=2021-03-16 |title=Tiny Wormholes May Be Usable for Interstellar Communication |url=https://thedebrief.org/tiny-wormholes-may-be-usable-for-interstellar-communication/ |access-date=2023-01-06 |website=The Debrief |language=en-US}}</ref> Considering the immense energy or [[exotic matter]] with [[negative mass]]/[[negative energy]] that current theories suggest would be required to open a wormhole large enough to pass [[spacecraft]] through, it may be that only atomic-scale wormholes would be practical to build, limiting their use solely to information transmission. Some hypotheses of wormhole formation would prevent them from ever becoming "timeholes", allowing superluminal communication without the additional complication of allowing communication with the past.<ref name="urlSkinny wormholes could send messages through time | New Scientist">{{cite web |url=https://www.newscientist.com/article/dn25596-skinny-wormholes-could-send-messages-through-time/ |title=Skinny wormholes could send messages through time &#124; New Scientist }}</ref>
