There are fire resistant plants on Earth that you can model it after. Redwoods are pretty hard to burn. I recall seeing a video of a guy holding a blowtorch to a piece of redwood, and it not catchi...
A long escarpment is a perfectly normal geological feature here on Earth without the need for a meteor, and in fact plate tectonics can also raise parallel ridges like this. All your model would r...
The main problem is to establish a common time standard to base your local clocks off. Then it doesn't matter if your local time system differs from that (for example, you will want to base your pl...
You could have plants that fly instead of float. Something like a biological spring that winds up, and when the plant has produced enough seeds and such the root releases and the spring unwinds spi...
So I remember a story with a submarine that was powered off a big flywheel, and every once and a while they'd have to power up the engine to spin the flywheel back up. Lots of other people have ...
I think such plants would have no use for leaves. Leaves are basically solar energy collectors, and since your plants do not do photosynthesis, they have no use for them. I'd expect all the energy ...
Bigger planets don't always have greater masses. Remember, mass and volume are related by $$M=\rho \frac{4}{3} \pi R^3$$ where $\rho$ is density. Make $\rho$ small enough and the gravity and be as ...
Yes, there's an alternative. Plants using chlorophyll must, to the best of my knowledge, take in CO2 and put out oxygen. So chlorophyll is a no-no. Fortunately, not all photoautotrophs use chlorop...
First, an "acceleration shield" in the true sense of the word is impossible. However, one could imagine something close to it: The reason why acceleration affects you is that it actually doesn't a...
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...
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 ...
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...
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 ...
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...
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...
I think all the virus would need to do to have that effect is to dramatically ramp up the levels of adrenaline and testosterone. I think it is perfectly possible that a custom-designed virus could ...
I've been slacking lately on biology questions, so I'll try my luck on this one. Good news! These things aren't so far-fetched! Meet the giant tube worm (see also here). (Original image source...
You need to figure out what environmental reason there would be to not be symmetrical. The asymmetric earth creatures I can think of are crabs and lobsters, where one claw is for crushing and the o...
Fire breathing developed as a way to help raise their young. Being reptilian, dragons lay eggs, but eggs need warmth to mature. Because dragons are solitary creatures, and because dragons will e...
Since the virus is airborne, you could spread it using a chemical fog. The Tom Clancy book Executive Orders has terrorists using a modified spray can at convention centers to spread a virus. Tha...
There are two parts to this question: Could a massive planet amass large quantities of nitrogen and oxygen? Could these gases be the main ones the planet is composed of? Giant planets relativel...
I think there would be mainly three types of reactions: Those groups who think that apes should be given human rights would use that as additional arguments; also if you can speak with the apes, ...
If you say you want to make the speed of light 100 times as high, you have to say what you want to keep constant. I'll assume you want to keep constant the sizes of things (because if light is 100 ...
How could it be possible? Obviously the black holes cannot be the source of light for the planet, so we need four bodies: The two black holes, a star and a planet. Moreover, the star should be in ...
For many uses, I agree with this answer that you would see local internets serving live content (as now) backed by interplanetary replication. The technology exists today to manage large data repo...
