In contrast with popular beliefs, physics and space is fun and fascinating. Our universe is far more remarkable and exciting than what we expect. If you are the type of person who likes science trivia, here are some amazing physics and space facts you might enjoy sharing with your family, friends, classmates, or even complete strangers.

Just how fast is the speed of light?

The speed of light is also known as the universal speed limit. So, how fast is the speed of light as it travels through a vacuum (empty space)? Well, it is 186,000 miles/second or 299,792,458 meters/second. Will you get arrested if you exceed this speed limit? Nope. No one or nothing can go any faster.

How heavy is the Earth?

The question is not how heavy the Earth is, but what is its mass. Basically, weight measures an object's gravitational pull. Thus, your weight depends on your location. This means you are heavier here on Earth than on Moon.

On the other hand, mass refers to how much matter an object is made of. To answer the question, the Earth's mass is around 5,972,000,000,000,000,000,000 (5.972 sextillion) metric tons. That is a lot of stuff.

Is the Earth round?

We have been taught ever since grade school, the Earth is round. The truth is, the Earth is not round. It is what we call an oblate spheroid. It bulges at the equator and is slightly squashed down at the poles - the equator is about 25.41 miles (40.89 kilometers) wider than the poles. The difference is not really noticeable in many photos. Skittle and M&M candies are extreme examples of oblate spheroids.

Is space the coldest place there is?

The space is very cold. You might want to bring layers of jackets if you go there. But is space the coldest place there is? The absolute zero temperature on the Kelvin scale (-459.67 Fahrenheit or -273.15 Celsius) is the coldest theoretical temperature. In this temperature, there is no movement even at the molecular. The temperature in space is around 3 degrees Kelvin.

Where would you find the biggest Milky Way Bar?

No, we are not talking about candy. We're talking about something unimaginably big. The biggest Milky Way Bar is found at the center of our galaxy, with approximately 27,000 light years in length.
