Astronomy… Is It Possible To Construct Wormhole Using “Only” Matter On Multimetric Gravity? (Cosmology / Quantum) 28 Feb 202128 Feb 2021 Friends, it is a well-known fact that solutions to general relativity which describe traversable wormholes require the existence of exotic matter, i.e., matter which violates the null energy condition (NEC).…
Astronomy What Are The Effects Of Different Dark Energies On the Mass Of Wormholes? (Cosmology / Astronomy) 27 Feb 2021 In recent observations it is strongly believed that the universe is experiencing an accelerated expansion. The type Ia Supernovae and Cosmic Microwave Background (CMB) observations have shown the evidences to…
