The yo-yos was actually first made by the Duncan yo-yo demonstrators in the 1930s and the yo-yo today is now considered a weapon due to the Duncan brothers making up the rumor of it being a weapon, this was done as a marketing strategy.

The Fizz is incredibly durable, and is slim enough to fit into small hands, making this yoyo an ideal choice for young children.

Like the Luminator before it, the Sage Yoyo is easy to pick up and play. It comes with a thin bearing that plays very responsive and can sleep for 30-45 seconds with a good throw.

• Fizz yoyo – #1 Beginner yoyo.
• Wedge & Replay Pro yoyos – Best Plastic (Unresponsive)
• The Snack yoyo – Best Pocket yoyo.
• Canon yoyo – Best All-around yoyo (1A, 3A, 5A)
• Civility yoyo – Best for Learning Tech and Trick Development.
• Edge Beyond yoyo – Best Competition yoyo.
• Ethos yoyo – Best All-around for Learning Tricks.

If you stopped time, all light and sound would stop, too. In some interpretations, this would leave Strine instantly deaf and blind in his frozen scene. When you slow down electromagnetic waves (light) and pressure waves (sound), you get waves of a lower frequency.

In the limit that its speed approaches the speed of light in vacuum, its space shortens completely down to zero width and its time slows down to a dead stop.

As a rule sound travels slowest through gases, faster through liquids, and fastest through solids. The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour. Speed of light in water = 226 million m/s or 205,600 mph.

Wormholes are sci-fi staples; over the years, many stories, books and movies have sent their protagonists zipping between widely separated locales via these cosmic shortcuts. Wormholes are possible, according to Einstein’s general theory of relativity, but nobody has ever spotted one.

We place two massive objects in two parallel universes (modeled by two branes). Gravitational attraction between the objects competes with the resistance coming from the brane tension. For sufficiently strong attraction, the branes are deformed, objects touch and a wormhole is formed.

Primordial wormholes are predicted to exist on microscopic levels, about 10–33 centimeters. However, as the universe expands, it is possible that some may have been stretched to larger sizes.

As long as a wormhole has a greater mass than any black hole it encounters, it should remain stable. If a wormhole encounters a larger black hole, the black hole may disrupt the wormhole’s exotic matter enough to destabilize the wormhole, causing it to collapse and likely form a new black hole, Gabella said.

The usual story of the Universe has a beginning, middle, and an end. It began with the Big Bang 13.8 billion years ago when the Universe was tiny, hot, and dense. When things finally cooled enough for the first hydrogen atoms to form, the Universe swiftly became transparent.
