Dr. Brown's objections to Boomer's story are precisely the objections that I have posted over that past few years - I raised some of the objections
with Titor directly.
The mass of the singularities is far too small to have the desired effect;
The injected electrons simply result in a maximally charged BH (i.e., q + e > M) where "q" is angular momentum and "e" is the electric charge.
Many more objections...
One has to see in his or her mind what occurs when his gadget is activated given where the BH's are located, what surrounds them and where the
intended time traveler is relative to all of this.
Upon activation, if it really worked, the event horizons expand to engulf the components that make up the gadget long before the time traveler is
affected. Some components simply "disappear " behind the EH and are no longer a part of the "world" where Boomer is sitting in his vehicle...the
gadget stops working because parts of it have been removed.
If you blow up the cutaway schematic drawing of his gadget (300x works nicely) you can see that whatever it is it is a vacuum tube based piece of
technology. I dunno - but I don't forsee vacuum tubes in a time machine.
Dr. Brown also points out (as I have also done) that the gadget as described would be out putting very hard gamma radiation (and not x-rays as Boomer
said) due to Hawking Radiation. He'd be nuclear toast long before his two hour ride was completed.
The original radius of his event horizons, as he described them, was less than the radius of an electron. He then pumped up the mass and angular
momentum of the BH's by injecting electrons.
Somewhere in his physics research for the story he overlooked some very basic ideas: Pauli Exclusion Principle is one thing he overlooked. Just how
many electrons can you pump into a volume that starts out with a volume less than that of an electron?
The BH will very quickly have such a huge negative charge that pumping in further electrons would require the electrons to have a velocity very near
He also neglected Heisenberg Uncertainty. The drill with the electrons was to increase the angular momentum of the BH's so that they are "spun
up." This means that the electrons must be pumped into the EH along very precise vectors such that each electron adds to the angular momentum. To
do so requires him to have very precise information about the location of the electrons being pumped in. But he then begins to know less and less
about their velocities (which is required because of the huge negative charge). If he then begins to focus on the electrons' velocities he no longer
has the requisite knowledge about their locations.
Even if he were to magically overcome Exclusion and Uncertainty, how many electrons are required to pump up the mass sufficiently so that the EH
expands from a radius less than an electron to a radius of ~3 meters (to engulf the entire vehicle)? How long does it take to pump in several
trillion tons of electrons? Does his vehicle have a standard or heavy duty suspension so it can hold up the several trillion tons without being
I saw a reference to the "bent laser" in a post a few pages back. Take a close look at the photo. The effect is supposed to depict the bending of
spacetime in the area of the activated gadget. Yes, the laser is bent. Look at the smoke and the hand. For some reason spacetime seems to be rather
Nice photo - poor attempt at showing curved spacetime.
It's a good thing that it's not real. The "hand person" would be smashed flat by the tidal effect and the molecules of his body would be ripped
into sub-atomic particles if spacetime was as severely warped as the photo suggests.
Boomer's story is pretty good sci-fi. But it's really bad sci-physics.
Note: I've switched between using Titor and "Boomer" in the post. It's the same person. I gave him the nickname "Boomer" while we were
posting on P2P.
