[@AdamNisbett]

The crazy thing about being on a planet with different gravity is that it’s not like you just lost weight and are lighter. You still have the same mass and so have the same inertial momentum when you are moving. So it’s still takes just as much force to get your body moving, there’s just not as much force pulling you down, so it can actually be difficult to walk as you have less frictional grip on the ground, but still need just as much force to move you forward.

[@curtism-w6b]

You won't fall off the edge of Mars. But if an object is small enough, you could escape it's gravity and fall off. Well, technically, you can't fall off anything in space. There's no up or down. You'd just float away into the vacuum of space 😳

It’s not about how small the object is. It’s about how fast it’s traveling. For a planet or moon with less gravity you don’t have to go as fast to reach “escape velocity” which is the speed and therefore momentum necessary that you won’t eventually get dragged back in by the gravity of the planet.

[@beesnestna9544]

In a nutshell, we can do all the mathematical calculations, run all the computer simulations, use countless illustrations of various types, but the human mind still cannot truly appreciate, fathom nor comprehend the astounding distances, sizes and masses (of objects) that make up the universe. Everything we know, after thousands of years, was learned from observations right here on Earth or from the most infinitesimal distances (comparatively speaking) away from Earth. Even a size comparative illustration of the Earth next to the Sun does little to convey the true enormity of the Sun or its mass, and then consider that the Sun is a "Dwarf Star" that is equally as small as the Earth when compared to many other stars. Take for example, the north star "Polaris". Comparing the size of our sun (Sol) next to "Polaris-A" would be similar to placing a marble (or possibly a golf ball) next to a basketball. Then consider that Polaris is approximately 323 light years away. That means when we see the north star in the sky at night, we're seeing what it looked like on this day 323 years ago! In essence, we're looking back in time! Also, imagine if we could travel at the speed of light (roughly 186,282 miles per second - an impossibility according to physics); it would take us 323 years to reach Polaris! Even if we could travel 10x that fast (Warp factor 10), it would still take over 32 years to reach it! The distances and sizes in "Space" are just incomprehensible! Amazing stuff, no?! 😮 And just for good measure I'll toss this in. Everything in our universe is made up of atoms. Atoms are made up predominantly of empty space. Therefore everything we see and touch is made up mostly of empty space. Because protons, electrons and neutrons revolve infinitely fast around the nuclei of atoms, they merely give us the illusion of mass (or solid objects e.g., a floor, a vase, a mountain, etc.). Let that sink in a while! 😂Peace.

7:55 Planets aren't flat disks, they're spheres (ish). They're just wayyyyyyy too big for anyone to notice the curve from the ground. The curve is obvious if you look at like a tennis ball because its diameter is like 4-5 inches. The Earth's diameter is 12 742km and the moon's is over 3 800km. Mars is in between, but I forgot what it is. Point is, you won't see the curve from the ground, but you still can't fall off because there is no "edge". Gravity pulls everything to the center of the planet they're standing on. "Down" is wherever you're being pulled towards (see "which way is down" by Vsauce for a clearer explanation 😅. The reason you don't fall to the center of Earth is because the ground is in the way. Gravity also extends to infinity, but the farther you are from an object (planet, asteroid, moon, etc), the weaker gravity is and by the square of the distance. So if you move 1km away, the gravity will be roughly a million times weaker there. Now that I say it, it sounds weird, but the maths don't lie... Here's the equation: F = G(m1*m2)/r^2 where F is the force, G the gravitatonal constant (6.67428x10^-11 m^3 kg^-1 s^-2), m1 is your mass, m2 the mass of the planet, and r the distance between the center of each body.

To answer your question on gravity its pulls to the center of the planet, all planets have it and if i remember right the bigger the planet the stronger the pull so you will feel heavier on a bigger planet and lighter on a smaller one. Also in space there is no right side up or upside down.

[@Novaximus]

7:50 To better understand "orbiting" around a planet vs gravity and sticking to it....Imagine if you were on a cliff and jumped. You'll eventually hit the ground due to gravity. Now imagine you make a taller cliff and could jump really far off of it. You almost hit the ground but because you were so high up and jumped off really far ---> this way direction that as you approach the ground you're missing it because the world in a sphere. What you're doing is essentially falling forever. Going around and around the planet. The gravity is pulling you down but you're also so high up that you're falling in parellel to the earth's curved surface. That's "orbiting" If you were to jump any lower and had no sideways velocity then you would get sucked straight back down to earth.

The majority of what about the Universe, has been learned in the last 50 years and it's amazing how much we don't know.

[@julianhinojosa9695]

Millie, good to see you're more comfortable with us to sit in the hot seat. Lol

[@melissabonham893]

Hello from Florida USA!! Absolutely love your channel! What a pleasant surprise to see Millie up front. Fabulous! May I suggest watching the movie The Martian staring Matt Damon. Very interesting to think about being stranded on another planet. Love all of your videos, especially the cooking pecan pie!!! Love from across our little planet!!

Pluto is a planet. Want to fight about it?

[@noneofyourbusiness3288]

A still: we are in size several magnitudes closer to the size of the observable universe than we are to the smallest possible distance: a plank length. Meaning we are bigger compared to the smallest (possible) thing, than the biggest (observed) thing is to us.

[@jimmymapes3411]

Ok I'm old school. Pluto is a planet. You won't fall off Mars. And yes, Kazoo was green and came from Mars.

7:40 - gravity is a force that attracts proportionally between all objects of mass. You have your own personal gravity, it's just your proportional mass is so small that your gravitational effect is inconsequential. Gravity only has one directional exertion, which is towards. There is no up or down, left or right, relative to gravitational force. A person at the south pole of the earth is feeling the same gravitational 'pull' as a person at the north pole, or the equator, or anywhere on the earth's surface. Gravity on mars, or any planet, or any object of mass pulls with equal force, relative to it's mass from any direction. People can't walk to a point and fall off the edge of Mars, because no matter where they walk, Mar's gravitational pull is always pulling them towards it's centre.

Love the idea that they think there is gravity on the moon.

[@marcjennings6267]

The average time for a radio signal to reach mars is about 11 minutes, depending on the planets positions from one another…

[@Ladythyme]

Definitely mind blowing…. They are worrying about other galaxies etc. but we can’t even control what happens on Earth….yup I’m thinking us Earthlings need to get over ourselves

[@Yeshua9596]

Didn't even watch yet and i liked your vid lmao you guys never fail to entertain! Love from 🇺🇸!

[@Novaximus]

I don't like the idea that if I needed more air to breath I'd have to travel millions of miles to get back to earth for it. And a juicy cheeseburger. I'd have instant regret.

[@wrin1010]

Our sun will die before we could reach another galaxy. That's why I love Star Trek. Possible warp speed and folding time. Using man made black holes to travel. We live only 80 years on average. So make the best of your life and believe there is an afterlife. Good video.

[@careyhouser392]

That's wild and crazy to think about

[@robertvien5693]

Being small to me gives me a comfort

[@speciesspeciate6429]

Science facts, yay. Happy New Year

So about the gravity question. There is a video explaining how a humans physiology might develop differently if they were born on other planets in our solar system. For example, Mars has a lower gravity (3.721 m/s²) than Earth (9.807 m/s²), so a human would more than likey have a "stretched" bone structure compared to what we know on Earth.
