Let's do a bit of math.
According to Wikipedia, the mass of the moon is $7.3\cdot10^{22}\,\rm kg$ and its average orbital speed is $1.0\,\rm km/s$. That means its kinetic energy is $3.7\cdot 10^{28}\ …

How would we see the world if we could see polarized light?
With many more than three colour receptors, our colour TVs, using just three colours for display, would not come even close to showing all the colours of the world. Moreover, LDCs inherently work with …

Making a lethal, hard to cure virus?
A possible way to have the virus spread quickly yet be deadly is to have a double effect. Shortly after infection, it basically acts like the common cold. The common cold spreads quite effectively eve …

What would happen if a virus could not be cured or contained?
First, the deadliness of a virus can vary widely from mostly harmless (Herpes) to very deadly (Ebola). However, note that even for Ebola, there are people who survive without treatment. Indeed, Ebola …

Flu Rage virus used as interstellar weapon?
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 cau …

How might one create a room in which time flows faster?
Here's one method that doesn't rely on either gravitational time dilation or simulation:
If you look at the basic equations of quantum mechanics, you notice that if you scale all masses by a common f …

Ways to make contact with aliens on a much larger size scale?
Well, some mosquitos when flying make a noise that is clearly audible by a human (as everyone who had one in the room at night knows from painful experience). So I assume that ship has the same abilit …

When will uploaded minds be a reality?
Never.
The problem is not being able to simulate a human brain; that one I consider possible, and probably even achievable on affordable hardware at some time in the future. The problem is taking an …
