This is how Santa can make his worldwide gift delivery in a single night.

What is Santa's secret? The world's children's toys are delivered in one night by an overweight old man riding a magic sleigh pulled by eight winged reindeer.

There is, however, one catch. They must trust in him.

There's a good chance you're wondering how this is even possible in the real world. Could Santa Claus, with the appropriate tools and methods, really make all of these deliveries? It's never been more difficult to play Santa now that the global population is over 7 billion. However, Santa is more than capable of meeting the challenge by combining the power of science with some Christmas magic.

The following is a list of how many homes Santa must visit and how far apart they are on average.

• That's what Wikipedia says, anyway.   Taking into account population growth since the time of the survey, we can estimate that there are around 1 There are approximately 6 billion households in the world.
• The average distance between any two houses on Earth is zero, given that there is only about 25 million square miles (65 million square kilometers) of habitable land. 138 miles (0 225 km)
• More importantly, at least in the USA,   In any given year, 31% of homes will have Santa "pretend to" visit. (Pretends   to My heart laughs at your icy skepticism. Pew )

In total, Santa must deliver gifts to roughly 500 million homes, with an increasing mean separation of zero. 205 miles (0 If Santa has to skip some houses (a total of about 33 km), he won't get to them all.

Santa has a lot on his plate, including a lot of kids to see and a lot of miles to travel, but not a lot of time. At least Santa is close to the winter solstice during his 24-hour Christmas delivery window, which begins at sundown on Christmas Eve in Russia and ends just before sunrise on Christmas Day in Alaska. which means he can spend more time in the North.

Because of daylight saving time, the international date line, and regional variations in sunset and sunrise times, Santa has no more than 42 hours to deliver to all 500,000 homes around the world. With such a short window, Santa must complete the following tasks:

• drive the average of zero miles between dwellings. 205 miles (0 distance of twenty-three miles (forty-seven
• leave his sleigh and sneak into the house,
• Send all the gifts,
• consume all of the leftover treats,
• and then sneak out, hop on the sleigh, and move on to the next residence.

It's hard to fathom how a single person could perform all of those actions 500,000,000 times in 42 hours. (In fact, countless parents of children who have ever believed in Santa Claus can attest to how difficult it is for even one household to pull off.) Santa Claus, however, is not daunted by the enormity of his task.

Santa has only 42 hours to visit 500 million homes, giving him a total of 300 microseconds (0.03 seconds). 0003 seconds) to finish all of his chores for the house

Impossible as it may Perhaps for a typical human equipped with age-old tools. I recently told Big Picture Science and the SETI Institute that Santa Claus might be the greatest scientist in the world. Indeed, if you believe in science, you should also believe in Santa. I'd like to address all of your possible concerns by examining

1.) It's impossible for Santa to visit every home in one night. When compared to the vehicles we've developed, these velocities aren't too bad, and they're certainly fast enough for Santa. In any case, not when compared to the speed of light and relativity. If we want to shift that zero 205 mile (0 The average distance from house to house is 20 miles (32 kilometers), so Santa only needs to travel at a speed of about 1,367 miles per second (2,200 kilometers per second).

I suppose that sounds ridiculously fast when put next to a regular sleigh, let alone a car, train, or supersonic plane. However, that is much slower than particles emitted by radioactive atoms, particle accelerators, or even the Sun, all of which travel at speeds much higher than 1% of the speed of light.

There's no reason Santa can't make it from house to house in record time as long as he gives his reindeer plenty of food and drink along the way.

The heat and acceleration would be too much for an open sleigh with Santa inside. There's the temperature issue first. The atmospheric friction alone could be catastrophic at such high speeds; the only things we know of that collide with the atmosphere at such high velocities are meteors and satellites that re-enter the atmosphere.

When traveling, Santa would have to lose a huge amount of heat—somewhere around a few trillion Joules per second. You might think that Santa, flying unarmored through the atmosphere at meteor shower speeds, would perish in the same way that a satellite does upon re-entry if he were to crash into the Earth.

However, you can escape in one of two ways:

• With a heat shield, he and the reindeer would be safe to travel through the dangerous environment. But if we think about a sleigh that is open on both sides, the rider will not be protected in this way. The second choice, however, has a chance to triumph even if this fails.
• With his highly aerodynamic vehicle, the air in front of him may be completely removed, leaving only a gentle breeze. Just make sure there's enough air for Santa to breathe, and we're good to go.

Keep in mind that the accelerations are somewhat more jarring. For most people, the idea of going from zero to sixty miles per second in one tenth of a second is terrifying, and the idea of passing out (or worse) from the acceleration is even more terrifying. With the assumption that you only feel 27 gs of force, where 1 g is the acceleration due to Earth, you can see how that works. In contrast, Santa needs 1 There are 51018 gs in this phrase.

Despite the fact that most people live in cities, the rapid acceleration and deceleration experienced by a person traveling from rooftop to rooftop in such short periods of time would have disastrous consequences.

Major John Beeding set a new record for human endurance by riding a rocket sled at 83 gs for a short period of time. John Stapp, who pioneered the idea that humans could withstand such extreme accelerations and decelerations, used his own body as a test subject for his devices in the 1940s and 1950s.

Santa can still deliver toys, he just needs to find a way to work around these limitations. To make it through this trip at these velocities and accelerations, all he needs is a way to keep his blood from clotting. A suit with enough pressure, combined with a biological turbine system more powerful than the human heart, would be more than enough to accomplish this feat.

The thought of Santa Claus probably doesn't conjure images of organ replacement surgery, but surely the joy of children around the world would be worth it.

Thirdly, how does Santa sneak into every home without a trace? You probably don't picture a chubby old man wearing boots traveling the world stealthily. It's understandable to consider bringing Santa inside using some sort of mechanical rig, whether through the chimney, the window, or some other entrance, but there's a better way, thanks to the laws of physics.

However, there is a certain probability that, in the quantum universe, if you are on one side of a barrier and run into it, you will not simply smash into it or bounce off. However, you could potentially reach the opposite side by digging a tunnel. The phenomenon of quantum tunneling is well-established, and it follows that there is at least a finite chance that even macroscopic objects will undergo it, albeit with an extremely small probability.

Possibly Santa has this phenomenon under complete control. Because of this brilliant plan, Santa can:

• I can walk into any house I want,
• any gifts he desired should be brought inside.
• just drop off his gifts wherever he wanted,
• and then leave with no one else, returning to his sleigh

I would never take money from Santa because he is the most brilliant scientist in human history.

Where did he get the presents so quickly? Bringing gifts to people doesn't have to be a time-consuming ordeal. Assuming Santa makes it to the right spot, all he has to do to deliver the gifts is drop them. You can bring them in at a very small, insignificant height above the ground, right under the tree, and then just let them go.

That's it There's just one more thing to do before the presents can be delivered to the next home.

5.) Digging into the holiday treats In fact, this is a brilliant solution. Santa needs a lot of fuel to pull his sleigh full of presents to 500,000,000 homes around the world, you see. You could, of course, convince yourself that your flying reindeer are magical and therefore could simply use their magic to solve the problem. Let's stick to the facts instead: even Santa Claus is subject to the law of conservation of energy.

How much effort is it, then, to ship all these gifts around the globe?

Santa probably has around 4 There is a weight difference of 5 lb. The total weight of all the gifts Santa needs to deliver to every home is approximately one million metric tons. (The night gradually fades into morning.) For comparison, the Antonov An-255, the world's largest airplane and the one used to transport the space shuttle, can only carry about 4,000 pounds.

However, rocket fuel is not only wasteful, but also prohibitively expensive. About zero Just.001% of rocket fuel's mass is converted into usable energy. But what if Santa's reindeer, the true engine of his legendary flight, could convert all that food into energy using Einstein's E=mc2?

Due to the efficiency of E=mc2, the mass of even a single small cookie would be sufficient to propel Santa and all the toys around the world from one home to the next. Naturally, Santa gets to enjoy all of the leftovers.

Many fictional Santa stories have him relying on gadgets, magic, or an army of elves to pull off their feats, but those stories are only for the skeptics who fail to recognize the true power of Christmas magic. After all, the first manned spacecraft to leave Earth orbit, Apollo 8, taught us an invaluable lesson that must never be forgotten. Here is a conversation from 50 years ago between mission control's Ken Mattingly and Apollo 8's Jim Lovell:

089:32:50  Mattingly HOUSTON, Apolo NIXON 8 [No answer ]
Mattingly, Apollo 8, Houston, 08:33:38
089:34:16  Lovell NASA Mission Control, Houston: Apollo 8 Successfully Completed
Mattingly 089:34:19 Hello, Apollo 8 Strong and unmistakable
Roger Lovell, 08:9:34:25 Just so you know, there is a Santa Claus.
Time: 08:9:34.31 Mattingly: Yes. You're the ones who know it best.

There is only one question about Santa Claus that our current scientific understanding has not yet resolved. I mean, when does he have time to pee with all those presents to bring?
