Based on the principles of physics, it is theoretically possible for a planet to have a donut-shaped structure. To maintain the stability of a donut-shaped Earth, it would need to rotate at extremely high speeds, resulting in shorter day durations. Consequently, the gravitational force at the poles would intensify,...

What would happen if the Moon took the place of the ISS? 🌕 If our satellite were positioned at the altitude of the ISS orbit (about 400 km), life on Earth would change forever. The Moon would fill almost the entire sky, eclipsing the Sun during every orbit—a journey that would take just 90 minutes. The gravitational pull of such a massive object at close range would instantly trigger colossal ocean tides hundreds of meters high, washing away coastal cities on a daily basis. Earth's atmosphere would gradually be stripped away into space, and the planet and the Moon would collide within a few days due to immense tidal forces.

On January 14, 2005, the Huygens probe descending through Titan’s atmosphere revealed one of the rarest views in space exploration. From Saturn’s moon Titan, Earth and the Moon crossed in front of the Sun as tiny shadows nearly a billion miles away. What makes it even more incredible is how rare the alignment was. A perfectly central Earth and Moon transit from Saturn’s system happens only about twice every 1,000 years. From that distance, our entire planet looked small enough to disappear into the sunlight.

Kudos to Kevin Kisner getting the REAL issue when it comes to the modern golf ball… While discussing the ball Ray Floyd used to win the 1986 U.S. Open at Shinnecock, he correctly references SPIN more than SPEED. Yes, the modern ball flys WAY farther, but the easiest fix would be to mandate more spin on the ball. The worst part of the ball traveling insane distances is that, because of no real spin, the mishits do not go off line NEARLY as much as they used to. If the spin returned, hitting a 350 yard drive would carry with it the HUGE risk of a mishit heading for deep trouble, even bringing many out of bounds back into play. As a result, not only would hitting a driver create far more drama than it currently does, it would cause most players to self regulate by hitting 3-woods and irons off the tee to keep the ball in play. This would effectively solve the distance problem because it would cause significantly longer shots to be played into the greens. Please, USGA PGA of America PGA of AmericaTOUR The Masters The R&A THIS is the path!

When a spacecraft leaves Earth, it doesn’t just fire its engines and head straight to its destination. In many missions, especially those going beyond low Earth orbit, there’s a more subtle and elegant strategy at play, one that uses gravity itself as part of the navigation system. This is often called a gravity assist, or a slingshot maneuver. But in the case of missions like #Artemis II, what’s being used is a closely related idea known as a free-return trajectory. At first glance, it might sound simple: the spacecraft goes to the Moon, loops around it, and comes back. But the physics behind it is anything but simple. Instead of relying on continuous propulsion, the spacecraft follows a carefully calculated path through the gravitational field of the Earth–Moon system. It is launched with just the right speed and direction so that, as it approaches the Moon, the Moon’s gravity bends its trajectory. The spacecraft is effectively flung around the Moon, redirected onto a path that naturally brings it back toward Earth. No major engine burn is needed for the return. Small trajectory corrections may still be required, but gravity does the heavy lifting. That’s the key. This kind of trajectory is not just efficient, it’s also safe. If something goes wrong with the spacecraft’s engines or onboard systems, gravity itself ensures the return. It’s an inherent backup plan, built into the trajectory from the very beginning. The same fundamental idea appears in gravity assists used across the Solar System. When a spacecraft flies past a planet, it can gain or lose speed by exchanging momentum with that planet. From the spacecraft’s point of view, it’s as if it has been accelerated without using fuel. In reality, it has borrowed a tiny amount of orbital energy from the planet itself. That’s how missions like Voyager reached the outer planets, and how probes continue to explore regions far beyond what their onboard fuel alone would allow. But there’s an important distinction. An interplanetary gravity assist is typically used to change speed and direction, often increasing the spacecraft’s energy. A free-return trajectory, like the one used in Artemis II, is designed for something more specific: a path that naturally loops back to Earth without requiring additional propulsion. It’s less about gaining energy, and more about shaping a trajectory that guarantees a return. To understand why this works, it helps to stop thinking in straight lines. In space, motion follows curves defined by gravity. The spacecraft is constantly falling, first toward Earth, then toward the Moon, and then back toward Earth again. What looks like a loop is really a continuous free fall through a changing gravitational landscape. This way of navigating space reveals something deeper. We tend to think of engines as the drivers of motion, but once a spacecraft is on its way, gravity does most of the work. The art of spaceflight is not just about thrust. It’s about knowing when not to use it. #GoodLuck #Artemis NASA Artemis

🧵THE OBJECT ORBITING EARTH THAT ASTRONOMERS WONT CALL NATURAL (1/6) A small object called Sar2901 recently passed Earth and entered a temporary orbit around the Earth-Moon system and people are going wild. When the Minor Planet Center looked at the observations, it couldn't decide whether Sar2901 was a natural mini moon or if it was an artificial object. It has now delayed giving it an official minor planet designation because if they did it would mean accepting that the object is natural and they don't know that it is. That's the official position of the organization responsible for collecting and publishing the orbits of asteroids and comets. Sar2901 is now beyond the reach of any current observations but it should become visible again in November, when astronomers might finally learn what has been moving around us.👇

The 7 astrological bodies affect us and life on this planet more than you think. The gravitational interactions between the planets, the Moon, and the Sun create the axial and apsidal precessions, and these directly affect Earth's climate and life on the planet. In other words, the Geophysical Event is caused by this interplanetary interplay. If the planets, the Sun, and the Moon govern the short and long cycles, then they also have an immense influence on our individual lives. Just as the Moon causes the ocean tides, it also affects us. Even a small change in the size or distance of a planet like Mars would completely change life on Earth. So now do you understand why the planets have long been associated with gods and regarded as the rulers of the aeons?

Auroras danced across Alaska’s sky last night.😮🌌 A breathtaking sign that Earth is wrapped in a powerful protective shield. Charged particles from the Sun hurtle toward our planet at extreme speeds, but Earth’s magnetic field deflects and guides them along invisible pathways. As they funnel into the upper atmosphere, their energy is released as waves of light. Without this magnetic shield, Earth would be exposed—and life as we know it wouldn’t be possible.

On April 26th, 2026, the Japan Meteorological Agency's Himawari-8 satellite captured a full day of Earth. Every ten minutes, for twenty-four hours, it photographed a complete hemisphere of the planet. One hundred forty-four individual photographs. No editing for content. No compositing. No CGI. No green screen. No hologram. No drawings. These are photographs, assembled into video. Himawari-8 is a geostationary weather satellite operated by Japan. It orbits at roughly twenty-two thousand miles above the equator, remaining fixed over one spot on the planet, orbiting at the same rate Earth rotates. It was launched in 2014. It takes photographs of Earth in visible light and infrared. It does this every ten minutes, every single day, year after year. These images are available to the public. Meteorologists worldwide use them for weather forecasting. News organizations use them. Scientists use them. You can access them yourself right now. What you're seeing over that twenty-four hour period is the terminator line moving -- the day-night boundary shifting as the planet's rotation carries different regions into and out of sunlight, all viewed from a fixed point in space. It is not a composite. It is not a trick. The curvature you see is not distortion. It is not perspective compression. It is the actual shape of the Earth as photographed by an independent satellite operated by a nation with no interest in perpetuating a NASA conspiracy. This is what Earth looks like from space. This is the globe holding atmosphere in place with gravity as you witness weather patterns moving across its surface. This is reality. (No fisheye lens was harmed in the making of this video.)

Most of us grew up seeing simplified diagrams of the Hubble Space Telescope and assumed the James Webb Space Telescope follows a similar path around Earth. In reality, it operates in a very different region of space. It is not orbiting our planet in the traditional sense but instead travels around a point about 1.5 million kilometers away known as the Sun–Earth L2 point, keeping pace with Earth as both move around the Sun. This location is often described as a gravitational balance point, but it is not truly stable or neutral. JWST does not sit still there; it follows a controlled orbit around L2 and requires periodic adjustments to stay on course. The result is a delicate, engineered dance between gravity and motion, where the telescope remains aligned with Earth while staying far from its heat and light, allowing it to observe the universe with extraordinary clarity.

True story.. we had a mean goat on the farm.. we never allowed it out of the pasture. If you went walking it would always try to knock the heII out of you. It got out one time and as grandma was walking to her massive boat of a Buick to go to church it snuck up and rammed her hard enough to break her hip.. no one on earth seen that goat ever again ☠️🪦

Martian giant transplanted to Earth: what would Olympus Mons actually look like? 🌋 Imagine a volcano so colossal it makes Everest look like a gentle hill. Rising a staggering 26 kilometers from base to peak, Olympus Mons wouldn’t just scrape the sky — its summit would punch clean through the clouds, slice past the stratosphere, and stand higher than many commercial airliners ever fly. From the ground it would tower over the planet like a natural space elevator, a single unbroken ramp of rock and lava stretching into the edge of space. 🚀 And the base? Spread that enormous footprint across Earth and it would span roughly the distance from New York to Pittsburgh (or cover an area the size of Arizona). You could drive for hours across its gentle slopes and still feel like you were only halfway to the top — because this isn’t a steep alpine peak. It’s a vast, shield-shaped continent of cooled lava, so broad and gradual that the summit would often sit beyond the horizon. Drop Olympus Mons onto our world and every skyline, every mountain range, every sense of scale we know would suddenly feel tiny. One look and you’d understand why Mars still holds the solar system’s ultimate geological record.
