Why would any interstellar starship still bother with streamline body design?

One reason that might play a larger part than you'd think is actually aesthetics. Sure, a big ugly ball of components is the cheapest option now, but will it net you any sponsors for your next ...

Why would any interstellar starship still bother with streamline body design?

Space isn't a pure vacuum. There's still bits of rock and other debris floating around. Do you really want masses impacting your ship at fractions of light speed? Streamlined designs would have ...

How to reignite a sun?

Your planet was shaded by a ring in its orbital plane. From the persepective of your planet, the star gradually dimmed and went out. What actually happened is that the star tore apart a planet that ...

Earth becomes a rogue planet - how long can Iceland hold out?

Iceland can hold out indefinitely It would take 2-3 months before the average temperature on the surface to be below zero (the reason for this is that the ocean has tremendous heat capacity, inland ...

Why would any interstellar starship still bother with streamline body design?

A streamlined shape has more advantages than just reducing drag while travelling through some medium. The streamlined appearance is only on the outside. The outside also is the barrier between non-...

Can any manmade vessels float on ocean of liquid nitrogen?

Density of liquid nitrogen at 1 bar and 79 K is about 798 $g/l$. For comparison water is 1000 $g/l$. When compared with water a boat would sink about a 20% more once put in liquid nitrogen, but unless ...

Colonies on Jupiter

I wouldn't put colonies in Jupiter's atmosphere. The gravity down there is too high... it'll be quite unpleasant for normal humans to live in, and you'll need an awfully powerful rocket to get back ...

How could you keep a rogue planet warm(ish)?

Rogue planets can be kept warm. The key points can be found in the Wikipedia entry on rogue planets. Interstellar planets generate little heat nor are they heated by a star. In 1998, David J. ...

How to reignite a sun?

Rumors of the sun's death were greatly exaggerated. The sun didn't die. Instead, it entered a quieter phase. Unfortunately, this began at the same time as a global cooling event (damn those evil ...

How might people try to stop the world becoming a rogue planet?

Call your shot. Your incoming mass is near the size of earth - too big to move except with something else of comparable mass. Hmmm... Your world has an AI at its disposal that knows the site, mass ...

Why would any interstellar starship still bother with streamline body design?

Another additional reason: they need the extra surface. Contrary to popular belief, space is not cold. Space is just empty, and that means that it has no temperature, and the ship cannot pass any ...

Thorne Zytkow Planets $-$ Can a Gas Giant have a Neutron Star core?

A gas giant with a neutron star at its core is impossible. The gravity of a neutron star is pretty strong. It would end up swallowing all the matter of the gas giant, turning it into nuclear pasta. ...

The Frozen Star - Can U-238 reactors be used as a energy source for 10,000 years?

Non-fissile decay of radioactives (including uranium and thorium in natural isotope ratios) is believed to be the primary source of internal heat for rocky planets like Earth (or, presumably, Taurus, ...

Iron-rich rogue planet that is 12x Earth's mass collides with the Sun; now what?

While the sun is just an average G type star it is impossibly large for our human mind to comprehend. About a million times larger than the earth. While a 12 earth-masses iron sphere sounds very ...

Can a planet have a different gravitational pull depending on its location in orbit around its sun?

Not easily. An orbiting object has the feature of being in free fall, which means that objects on it are not subject to gravitational pull from the object that is being orbited, no more than a person ...

Thorne Zytkow Planets $-$ Can a Gas Giant have a Neutron Star core?

The Roche limit around the neutron star that size is going to entirely contain the volume of the gas giant. So the mass of the gas giant will be shredded into rings and eventually be consumed by the ...
