I think it had something to do with that for every double in speed of an object , it contains 4 times as much energy . The EM drive doesnt follow that rule . The speed vs energy is more linear than squared . This makes it so fucking impossible and physics breaking . Ofc people are skeptical . With an EM drive we could reach 0 . 99 C at mediocre energy levels in the megawatt range , taking about 10 years . A kugelblitz drive with 16 petawatts of energy can max reach 0 . 72 c in 3 years , granted it is faster but holy fuck the EM drive is efficient , too efficient . <| sep |> The vasoconstriction with the 5 ht 2 a action in psychedelics is not psychological . If you are sensitive to one psych , you will most likely be sensitive to all . I think your best bet is to look into vasodilatorsmagnesium beforehand or consider combinations with disassociatives for their analgesic properties .
