NASA scientists detect evidence of parallel universe where time runs backward
- PaulHoule 6y agoThat's a strange way to think about it. More likely it was a dark matter particle (e.g. WIMP) that just happened to interact with the earth on the way out. Since they didn't find sparticles at the LHC and the parameters of a possible WIMP means there will be less "naturalness" in terms of the mass scale of the WIMP. It may be that the universe doesn't care about "naturalness" and that a lot of cosmology since the Guth era has been solving non-problems that people have convinced themselves are problems.
