Suppose that a planet whose size was somewhere between the sizes of Mercury and Jupiter impacted the Sun. Would such an event change local stellar activity sufficiently enough and for long enough ...
Are there realistic circumstances that a planet would be accelerated (either artificially or naturally) to the speed at which relic radiation becomes so blue-shifted that the planet is illuminated ...
I wonder if it possible for human civilization to evolve into two different civilizations. One is controlled by artificial intelligence (or by uploaded human minds) and the other is biology-based ...
Suppose a planet is covered with floating ice on top of water ocean and has no dry land. Would it be possible to establish permanent settlements, cities? Particularly I am interested in technolog...
In the future a major problem arose: a habit spread among the astronauts to make political statements upon landing on a new celestial body, often the statements were unpleasant to their government....
Suppose we have a binary star system and a planet at the L4 or L5 point of the orbit of one of the stars around the other. The planet is thus illuminated by the two stars from the same distance and...
Can non-intelligent life forms evolve to leave their home planet and travel in interplanetary space, for instance, grow on atmosphereless icy moons and transfere spores over interplanetary space?
What would happen if all dark energy (cosmological constant) instantly converted to radiation due to vacuum metastability event, while otherwise vacuum properties remain the same? Dark energy dens...
Suppose a civilization in which every possible appliance is a bio-machine. There are automobiles, but each one has a human-like head under the hood. Each datacenter is a bunch of over-grown brains....
How realistic is it that in the future someone invents plants that can live on top of the Antarctic ice sheet or are floating on ice like in the Arctic?
Is it possible for a planet to be heated and illuminated by a black hole due to Hawking radiation at the same intensity as by a star? What mass and size should a black hole have to produce the sam...
I wonder whether the birds or other flying animals heavier than air could evolve without trees of other protruding objects?
At speeds near the speed of light, interstellar particles and gas may affect the movement of the ship, and microscopic particles may even badly damage the ship. Would not it make sense to make the ...
I wonder if it is possible to install artificial equipment that would exhaust oxygen into air in otherwise CO2 atmosphere so that locally people could breath in open air without any kind of tent or...
