I also hated how she hauled a** when the allasaurous(sp?) attacked instead of trying to lure it away since she couldn't be hurt by it. That was messed up.   See 2 other replies

Even without shielding, not every electronic device needs shielding in order to tolerate a certain level of magnetism. It takes about the same strength magnet to erase/mess up a VHS recording as it does to disrupt an old CRT television/monitor, and you could use a magnet of that same strength against your watch, cell phone, etc. without any effect. As far as the human body is concerned, it is rather capable of withstanding significant magnetic fields without damage (magnetic resonance imaging (MRI), trans-cranial magnetic stimulation (TMS)), so even if the field was strong enough to knock out all electronic devices (which is apparently not the case), they would likely still have a long way to go before it had any long-term effects on their nervous system.   See 8 other replies

maybe the hologram is designed to react to the environment around it. The bigger question is how does the hologram project somewhere where there's no kind of technology to make it, and how does a mere image produce sound and also manage to see and hear everything around it. (but apparantly not smell)   See 2 other replies
