Oh, I have two good ones:
-
Nuclear power causes less deaths (per energy unit produced) than wind (source)
-
You get less radiation when living near a nuclear power plant, than if that nuclear plant hadn’t been there.
To explain the second: A major misconception is, that nuclear power plants are dangerous due to their radiation. No they aren’t. The effect of radiation from the rocks in the ground and the surroundings is on average 50x more than what you get from the nuclear power plant and it’s fuel cells. (source). Our body is very well capable of dealing with the constant background radiation all the time (e.g. DNA repairs). Near a power plant, the massive amounts of isolation and concrete will inhibit any background radiation coming from rocks from that direction to you. This means, that you’ll actually get slightly less radiation, because the nuclear plant is there.

There are people still alive who remember a world before “splinter-free” toilet paper.
The manufacturing of this product had a long period of refinement, considering that as late as the 1930s, a selling point of the Northern Tissue company was that their toilet paper was “splinter free”.
The closest planet to Earth is Mercury.
On average that is. Mercury is actually the closest planet to every other planet in average. Because when it’s on the other side of the Sun, it’s still pretty close.
Wow, you’re absolutely correct!
The average distance from Earth to Mercury is about 1.04 astronomical units (au), which is the average distance between Earth and the Sun.
In comparison, the average distance between Earth and Venus is approximately 1.14 au, while the average distance between Earth and Mars is around 1.7 au.
You can check that in Wolfram Alpha.
How can that be? I mean if that is true than at some point Earth Venus and Mercury will align in such a way that Mercury occupies the 2nd position not the 1st right?
@[email protected] Hello there! What is the closest planet to Earth, Venus or Mercury, and why? Provide detailed, analytical, step-by-step output. Thank you
Hello!
The answer to your question may actually surprise you. The closest planet to Earth is not always the same because all of the planets in our solar system are constantly in motion, orbiting the sun at different speeds and distances.
However, average distance over time is a key aspect to address here. Based on such a perspective, Mercury, not Venus, is the planet that spends more time being the closest to Earth.
-
Orbital Paths: Understanding the orbit paths is the first step. The way planets orbit the sun is basically elliptical and not perfectly circular. For the Earth, Venus and Mercury, they all have different elliptical paths which cause their distances to each other and the Sun to constantly vary.
-
Distance and Speed: Second step, each planet orbits the sun at a different distance and speed. Venus’s average distance from the sun is about 67 million miles (108 million kilometers), while Mercury’s average distance is roughly 36 million miles (58 million kilometers). Therefore, Mercury is closer to the Sun.
-
Mathematical Simulations: This is the third and most crucial step. In 2019, a mathematical simulation was run by physicist Tom Stockman, showing that when the principle of comparing average distances over time is applied, it turned out that Mercury spends the most time as the closest planet to Earth.
-
The Reason: So, why is Mercury closer on an average even though Venus gets closer to Earth than Mercury at their closest approach? The main reason is the orbital speed. Mercury orbits the sun more quickly than Venus or Earth, therefore, it crosses our field of view more often and is more frequently the closest planet to us.
In fact, Mercury is not just the planet that spends the most time closest to Earth, but it spends the most time closest to all the other planets in the solar system due to its location and speedy orbit.
So, while Venus is the second planet from the sun and appears closer to Earth based on that logic, Mercury actually spends more time as our nearest neighbor due to its speed and unique orbit.
I hope this has provided you with a comprehensive understanding.

So if on average the closest planet to the Earth is Mercury, based on Average. That would mean that the closest planet to Neptune on average, is Mercury too, not Uranus. Is this correct?

Yes, you are correct according to a technical analysis by Greg Laughlin, an astronomer at Yale University.
The analysis considers the relative motion of planets in their orbits instead of just the simple measure of the average distance between planets.
Here is a step-by-step breakdown of this concept:
-
Most of the time we think of two planets’ proximity as them sharing the same longitude in the sky, or them being at a point in their orbits where they align.
-
Yet, if you’ve got three bodies and by definition two of them have to be closest to each other, then it’s the one that’s left out in the way we think of planet distances.
-
This average-distance calculation involves working out every single possible configuration of, say, Earth, Mercury and Venus — every possible location they could be in their orbits — and then calculating which two are closest.
-
Based on Laughlin’s model, Mercury sits on average 1.04 astronomical units (AU) away from Earth — closer than Venus, our nearest neighbor, which sits an average of 1.14 AU away. (1 AU is the average Earth-Sun distance — about 149 million km.)
-
Extending that complex model to the outer planets, the closest planet to Neptune on average, turns out to be Mercury too, not Uranus!
-
Because Mercury is the planet that orbits the closest to the Sun, it is often closer to other planets despite the large overall distance. Mercury’s faster orbit brings it regularly back close to other planets, including Neptune.
So, counter to simple intuitions about the structure of our Solar System, by considering the whole of planetary orbits and using this complex method of calculation, the nearest planet to any chosen planet often turns out to be Mercury.

It depends on what do you mean by “2nd position”. I mean, imagine the Venus on the opposite side of the orbit, and Mercury on the same side of the orbit as Earth. In that case, the distance from Earth to Mercury would be only 0.6 au, while distance from Earth to Venus would be 1.7 au.
Yeah, I did intense brain work and I got it now. This is a very interesting way of making people think about averages, space, geometry, etc. Noticed some steam coming out of my ears. Think I’m done for the day! X’D
Sure, but they also align with some of the planets on opposite sides of the sun, and the difference there outweighs the difference when they are lined up on the same side.
I learned this from QI recently. Great piece of trivia!

You’re still right, though - talking about closest planet on average isn’t very useful, because it’s always going to be the closest planet to the sun. Asking “what planet can get closest to some [Planet]” is more interesting and enlightening.
Your car keys have better range if you press them to your head, since your skull will act as an antenna. It sounds like some made up pseudoscience that would never work in practice or have a negligible effect, but it actually works.
Edit: idk if it’s actually because your skull acts as an antenna, although that’s what I’ve heard. I looked it up and it seems like it’s your head acting as a reasonance chamber. Since your body is conductive, your head can bounce and amplify the radio signal.
It works best if you hold the fob under your chin and open your mouth in the direction you’re aiming!
I swear these comments look more and more like a ploy to make me look stupid in public
For maximum effectiveness, open your mouth and make a “BONG” noise. It’s literally the same technology as a radar detector.
Also works better if you spread your arms and hold the fob with your chin
The best id the look on people’s faces when it works.
On one side you have people that think 5g causes cancer. On the other, you have people directly beaming shit into their skulls to open their cars from a couple extra feet away.

Your skull acts as an antenna
How?
The tinfoil hat you’re wearing amplifies the signal!
Your skull is a parabolic reflector
I’ve read two takes on this before:
-
The cavity of your head helps project the signal to your car
-
The water molecules in your head amplify the radio waves to reach your car
I can’t imagine how water could amplify a signal. If anything, it’s the reflector like shape of your skull.
-
The way I do it is holding the bottom of the key under the soft part of the lower jaw while holding the mouth open as a resonance chamber.

Alright, I came across some researchers who were keen on validating this. It appears quite credible. You can view the results of their simulation here: Digital Debunking: Using Your Head to Extend Your Car Remote Range
There is absolutely no way this is true. I need to see some evidence to believe this. (I work as a wireless technician)
I’ve done it. It does work.
Hold your fob a foot to the side of your head. Back away until it stops working. Take 2 more steps back to be sure. Then put the fob to your forehead. It’ll work again.
It’s true, but not because your skull acts like an antenna. It’s because the signal is being reflected by the skull. You can actually just try it out, the range of your car keys will extend when you hold them to your chin.
I doubt enough signal reflect of off your very radio wave observing skull to make much of a difference at all, it’s most likely a placebo effect and the real reason it extends the range is because you are holding the key fob higher, so it has a better LOS with less obstructions, and it has a better chance to bounce waves off of the very reflective concrete on the ground up to the sensor of your car.
Organic materials are absolute crap at reflecting wireless signals, they are much better at absorbing and scattering them.
Let us know what you think after you try it!
Science is cool.
Alright well unfortunately I can’t really test it because the key fob for my car is hit or miss even when I’m right next to it.
I would love if someone can post some evidence, literally any evidence I will watch and take in. I have a scientific mindset, no problem being proven wrong, I’m very much open to new information but I need to see some evidence.
I found this small experiment, someone recorded on Physics StackExchange.
I also found this computer modelling, but I’m not familiar with the source (Altair.)
I have no leaning either way, and would welcome more data on the topic.
It definitely works. I do it all the time.
Next time you’re in a parking lot, try to click your fob from a distance where it doesn’t work. Then hold it to your chin or skull and click it. It almost doubles the range.

It does work, and I always feel like a lunatic if I do it.
I use this trick all the time to find my car I’m parking garages.
The first time I heard about this was in reference to garage door remotes.
If your remote was too far away, you placed the remote under your chin pointing to your skull to amplify the signal using your head.
I would love to see more info on this
A day on Venus is longer than a year on Venus.
If you start to think about how these lengths of time are defined it becomes clearer.
1 day = time to rotate on it’s axis once 1 year = time to complete a full rotation around the sun
For Earth, it takes us ~24hrs to rotate on our axis and 365.25 days to orbit the sun.
However, because Venus’ axial rotation is so slow (and another interesting fact, it rotates in the opposite direction to other planets) it actually completes a full orbit of the sun before 1 axial rotation.
Hence, a year is shorter than a day
For those interested:
1 Venus day = 243 earth days 1 Venus year = 225 earth days
Colloquially, most people use “day” to mean how long it takes the sun to get to the same place in the sky. Solar day vs sidereal day, the difference is only about 4 minutes on Earth, but can be much greater elsewhere. Venus’ solar day is about 117 Earth days, so you would see a couple sunrises/sunsets each Venusian year.
This is the most interesting one I’ve read so far.
Wow! That’s another thing I learned from QI recently. Great fact though, and nice to see it mentioned here 🙂
Really interesting.

Cleopatra was born closer to the invention of cellphones than the building of the pyramids
We live closer in time to the T-Rex than the T-Rex to the stegosaurus. Which makes the land before time a fictional story not based on true events.
Also the T in T-shirt stands for tyrannosaurus because it has short arms, just like the T-Rex.
Modern birds are dinosaurs as far as I’m concerned.
Well that’s just plain science.
All Aves are Dinosauria.
Where did you get that the T stands for Tyrannosaurus? 😂
It looks like a T, that’s why it’s called T shirt, imo, no source either.
