What would happen if two spaceships with Alcubierre warp bubbles were colliding? Would the space bubble collapse? Would they reject or push each other? Would they survive it without problems?
[This is an extension of this Worldbuilding.SE question.] So, general relativity states that: For example, objects in a gravity-less environment, but in a container accelerating at 9.8m/s^2 (such ...
In many countries, we number the years based off of proximity to an event in the Christian religion - we are over 2016 years past that date. However, in this scenario, religion has become less main...

I've read that the atmosphere about 60 km from the surface of Venus is very similar to the atmosphere on earth (the oxygen/nitrogen/CO2 levels and pressures are about the same). If there was a way,...
In a close future (in 100-200 years), humanity is in an energy/resource crisis and seeks new resources in the solar system. In my story, humanity, still in need after colonizing the moon, sends a m...
Exploring this new star system you have been pretty lucky to find an Earth like planet, with plenty of Oxygen, both in gaseous and in chemically bonded state (water, rocks, etc.). Just before you ...

Imagine a world much like Earth, except it is nearly tidally locked to its star, making a complete revolution every few thousand years. The planet is far enough away that there is a band of livable...
How can I make it so that an otherwise colonizable planet (or moon) can (entirely naturally) seem uninhabitable from a certain point on its surface? Background: There are a series of immovable gat...
By using antibiotics too frequently, some argue, we're setting the world up for a pandemic that we cannot treat. Every time an antibiotic substance is used, the bacteria that survive reproduce. Ev...
Let's take our regular "Great Blue Star Whale", with a mass of about 10 000 tons. That poor, poor whale is reaching the end of its life for whatever reasons. (Damn you! Space whale hunters!). It w...
