I cannot find much on the Lentz solution for superluminal travel since the initial reactions to the paper coming out in 2021. Has more mathematical work been done on this? I have my doubts it would work based on some of the criticisms I have seen but want to see if someone has really evaluated...
I am talking about unification of GR and QM. While the universe obviously knows what to do in the case of extreme conditions such as near the center of a black hole, it is not obvious to me that the current mathmatical frameworks (such string theory and LCG) are even taking the correct approach...
I will try to word this in a way that does not violate forum rules.
As I look at the struggles of string theory and loop quantum gravity and the struggles of trying to unify quantum mechanics and general realtivity in general such as the need for a framework for quantum physics which does not...
Does the Earth's orbit get very slightly larger over long periods of time due to the expansion of the universe? If so does it stay at the slightly larger distance or somehow does the energy to go back to the earlier orbit go somewhere else and if so where? If the orbit does not get slightly...
This is in reference to https://epjc.epj.org/articles/epjc/abs/2021/07/10052_2021_Article_9484/10052_2021_Article_9484.html in the European Physics Journal. In it it is stated a Casimir effect produced an energy pattern similar to what is needed for an Alcubierre warp field.. Is there substance...
Is there anything in the current theoretical world that says that the universe has to have started with an equal amount of matter/antimatter, probably none at all and everything was created from photons. Could it be that there just happened to be a small amount of matter around or at least a...
Once the water began to boil running up the reaction rate in Chernobyl unit 4, was there something different than the AZ-5 switch that the operators could have done which would have saved the reactor, or at least limited what happened to a meltdown?
Assume a Schwarzschild black hole. Near the event horizon other than Hawking radiation the behavior of matter and energy are fairly accuratly described by general relativity. How close can one get to the center (the singularity based on GR) before one must switch to a quantum gravity theory...
Is Jim Woodward's MEGA drive (https://www.nasa.gov/directorates/spacetech/niac/2018_Phase_I_Phase_II/Mach_Effect_for_In_Space_Propulsion_Interstellar_Mission/) likely to be for real? It seems to violate conservation of momentum. If it does how does it get away with it?
For this assume General and Special Relativity and not some of the quantum enhancements that have been proposed for them. If I were an astronaut who just crossed the event horizon on a galaxy center type black hole (big enough so I would not be immediately spaghettified) and avoided the...
Consider the following case. I will use the Earth's frame of reference to describe the scenario. Spaceship 1 is heading away from Earth using the Alcubierre drive and is at rest inertially with respect to it but is moving around 2c due to the spatial distortion effects of the drive. Spaceship...
It seems to me that if one had a functional Alcubierre drive and used it there would be some subluminal frame of reference in which time was going backwards for the spaceship which probably for it and for macroscopic objects in it which constitute a reasonably closed system would be a violation...
Does the past exist with the same "existence status" as the present i.e. somewhere (somewhen) people are leaving on the maiden voyage of the Titanic and somewhere (somewhen) else dinosaurs are wandering a younger Earth and it is just a case of "you can't get there from here" or is all that...
