You can look quite a long way back into the planet's history to answer this. Stars are formed from giant gas clouds called nebulae. When enough material accumulates in the nebula, it collapses und...
The scales are fairly similar for each component you mention: simply, as you have a greater understanding of all of those fields, you are able to harness more and more energy. The fields you menti...
While uploading human personalities to robots is out of the question, giving robots robot personalities, capabilities and intelligence is not. So: Robotically Controlled Suspended Animation This ...
It's already been done. Two species of moth, the hawkmoth and the tiger moth, use not just sonic but ultrasonic signals to defend themselves from bat attacks. The hawkmoth has only recently been d...
Volcanoes This is the way that comes to mind first. Drop bombs in every volcano you can find, empower full enough to cause an eruption, and detonate them simultaneously. This does obviously hav...
You are going to do a lot of damage. To restate the calculations PipperChip has done: $$ E_k = \frac{1}{2}mv^2 $$ $$ E_k = \frac{1}{2} \times 1.89 \times 10^{27} \times 13000^2 $$ $$ = 1.6 \times ...
I can see a few methods: 1. Cremation This is already a popular method of dealing with your body when you've passed on (at least here in the UK). A furnace doesn't take up much space, and especial...
As user3453518 says, this could happen for a short distance by inertia. I advise you to read his answer; there are some very good points made well in it. I'll add some science to it. The formula f...
There is much the same problem with teleportation. Let's compare the two: Teleportation I am going off what seems to be the most accepted method - it's not the only one. You are taken apart int...
It's a good idea but it will never happen. Becoming one nation is a good idea in terms of interplanetary commerce and diplomacy. If we're multiple nations, then we are pretty likely to have multip...
In any epidemic situation, there are a few important steps to work through: Contain Treat Learn Containment Fortunately for the rest of the world, Britain is an island. That takes care of a fa...
You might well be interested in my answer to this question, as it details minimum requirements. In it, I do some calculation to find out that to feed one average human for a year, you need 5110 pot...
Let's have a look at what methods of propulsion could be used. Sailing (wind) Paddle power Steam engines Sailing requires a large sheet of sailcloth attached to a mast. Paddles require big padd...
Air is incredibly light. It's hard to conceive of any materials that are actually lighter than air and sufficiently so to keep lift while under load. However, it might be possible to use balloons ...
Looking at the recent questions on dragons and aviation bureaucracy has got me thinking about some animals I could include in my story. I want these animals to be jet powered. One of the answers o...
tl;dr: Not without killing everything. Let's do some maths and actually figure this out. The specific heat capacity of water is $4.186 \text{ kJkg}^{-1}$. That means it takes 4186 joules of energ...
I'm really having trouble here. Let me outline my thinking: The First AI This is my major problem. If the first shackling AI is weaker than the next, which is weaker than the next, and so on, the...
This method seems a bit extreme... if you want to destroy Earth's politics but keep their culture, there are far easier methods. However, some solutions anyway: Nova Bombs In Andromeda, all Commo...
Plausibility To answer your implied question about the possibility of this high pressure: Jupiter's surface has a pressure of 100 times the Earth's. Cosmically, pressures this high are trivial: th...
