A Topological Drive for Spacetime Travel
Tingqi Cai, Yi Wang
We present a toy metric of spacetime travel from topological change. A bubble-like baby universe is detached and re-attached from our universe. Depending on where the bubble is re-…
Higher-order correction to weak-field lensing of an Ellis-Bronnikov wormhole
Tingqi Cai, Hyat Huang, Zun Wang +1
The gravitational lensing effect at higher order under weak-field approximation is believed to be important to distinguish black holes and other compact objects such as wormholes.…
Reconciling cosmic dipolar tensions with a gigaparsec void
Tingqi Cai, Qianhang Ding, Yi Wang
Recent observations indicate a tension between the CMB and quasar dipoles. This tension challenges the cosmological principle. We propose that if we live in a gigaparsec sca…
Lattice Simulation of Multi-Stream Inflation
Tingqi Cai, Jie Jiang, Yi Wang
We present the first lattice simulation to investigate the nature of multi-stream inflation. The simulation confirms the physical picture of multi-stream inflation, and with new fi…
