If You Threw Cookie Dough at the Sun, How Long Would It Take to Bake?

First, let's assume you are in orbit around the Earth's atmosphere, and you threw the cookie sunward at 25 mph. The most delicious of speeds.

Who Would Win in an All-Out Battle: Star Wars or Star Trek?

A classic debate! Good or Evil? Chocolate or Strawberry? Star Trek or Star Wars (excluding the Death Star)? But unlike those timeless questions this one really does seem to have a compelling answer. And its not what the majority seem to think.

Could You Launch Someone Into the Sun With a Big Enough Cannon?

In the spirit of making problems go away, sometimes you want to just launch a particular person/problem into the sun. So—could you? And just how big would the canon need to be?

How to Fix the Elevator

High rise buildings have used the same elevator system for decades. So why mess with a good thing? Because that good thing is one major waste of space. Friends, it's time to redesign the elevator.

How Iron Man's Arc Reactor (Probably) Works

Since the Iron Man arc reactor is a fictitious device, and it has no official scientific explanation in the Iron Man canon that I'm aware of, we might as well something up. Now, I'm mixing real science and fake science here. So physics nerds and comic-book nerds: Deal with it.

What to Do if the Pilot Passes Out and You Have to Land a Plane

So—your pilot passed out. The good news is the plane will probably have a sophisticated autopilot that can take care of most of the flying for you. The bad news is you will still probably have to land the damn thing. And since every aircraft cockpit is going to be different, it's not like you'd know exactly where to…

What Would Happen If the 20 Biggest US Cities Were Wiped Out With Nukes

Wiping out an American city, much less the largest ones, requires either blast yields well beyond the capability of any terrorist organization, or numbers of nuclear weapons that would make the terrorist organization one of the largest nuclear powers on the planet. This is particularly true of major cities such as…

How Close Are We to a Real Iron Man Suit?

If we are just talking about an armored suit that augments a human's strength and weaponry, then we're extremely close. But if we're talking about something with all of the primary abilities of Iron Man's character (i.e. flight, clean infinite power, and repulsor beams), that may never become a reality. The current…

Wearing the Suit from Edge of Tomorrow Would Basically Kill You

Those guns... would rip right off those armatures. Weapons, especially heavy weapons, cause a lot of recoil. I mean a lot of recoil. For comparison, I am going to consider the machine gun farthest back to be comparable to the US military's 240-G.

How Long Humans Can Live in Space—and What Happens if We Stay Too Long

How long can humans live in space? We don't know the answer to that. But every crew that resides on the International Space Station provides us information that we use to adjust our protocols and extends that period of time.

What Would Happen to the Internet if Mankind Disappeared?

Parts of it would die within a couple of days; if your access to it remained operational, some of it might remain partially usable for a year or two. All large complex systems require constant maintenance by huge staffs of intelligent people, and the internet is no exception. Like you've seen in future-dystopian…

What Would Happen If the Sun Ceased to Exist for Just One Second?

If you mean simply "is not visible" then very little, we'd have a second of darkness, not unlike an eclipse, and then we'd be back to normal. If on the other hand, you mean "ceases to exist momentarily" then you're talking about something else entirely.
