Introduce your sequence symbols temporally. Instead of broadcasting a single image of a "comic strip", broadcast a sequence of separate images that show the progression of the sequence markers. Fir...
An underground mine would remain undetected pretty much without any special precautions. Assuming they're not using heavy explosives, or anything like that, just drilling and excavating. The groun...
The big problem here is that the organism has to be able to decode its own DNA. Therefore the "decryption mechanism" has to be built-in in the organism. You can make it more obscure by hiding the ...
If you are concerned for only the safety of the crew, and not about re-using the Shuttle, you don't have to do a precision re-entry. You can re-enter anywhere and then bail out once the shuttle is ...
Not with light pressure. You need 300 megawatts of radiation flux for each Newton of force on the object (equivalent to the force exerted by a ~100 gram weight). However, you can use microwaves as...
Maps don't have to be geographical, they can also be diagrammatical, like the London Tube map. For instance, ancient Roman maps, the itinerarium, were graphs showing points of interest along a road...
There is absolutely no way to resuscitate someone who has been dead for long without basically magic-level-tech. When a cell dies all the metabolic functions cease. They stop ion transport which a...
There is nothing inherently dangerous about matter that has been created out of nothing (indeed, that's how all the matter around us has originally been created). However the method itself can be d...
Theoretically you could do this using magnetic stimulation of neurons. The magnetic field induces an electrical potential in the neuron which actives the neurons and it can work from (small) distan...
Counter-Earth is too massive to stay in any of Earth's L points. As Theraot points out only L4 and L5 are stable for objects much smaller than the main body. Another Earth would be too massive, and...
In addition to all the other answers, do also note that you don't need to necessarily obtain water, all you need is hydrogen and oxygen and you can create water. Hydrogen is the most common eleme...
This universe is fundamentally impossible, since some electrons have their worldlines terminated in a black hole. Without a full working model of quantum gravity, we can't make any firm predictions...
