Can You Travel The Circumference Of The Earth?

It would take you around 415 hours (a bit more than 17 days) to drive the 24,900 miles around the circumference of the earth if you could drive a car around the earth . However, since you can't drive a car around the earth, it would take you a lot longer to drive around the world.

How long would it take to travel around the Earth at the speed of light?

Light travels at a constant, finite speed of 186,000 mi/sec. A traveler, moving at the speed of light, would circum-navigate the equator approximately 7.5 times in one second .

How long would it take to travel around the Earth at the speed of sound?

What we're talking about here is like being in Boston and clearly hearing a noise coming from Dublin, Ireland. Travelling at the speed of sound (766 miles or 1,233 kilometers per hour), it takes a noise about 4 hours to cover that distance. This is the most distant sound that has ever been heard in recorded history.

How many miles would it take to circle the Earth?

Using those measurements, the equatorial circumference of Earth is about 24,901 miles (40,075 km). However, from pole to pole — the meridional circumference — Earth is only 24,860 miles (40,008 km) around. Our planet's shape, caused by the flattening at the poles, is called an oblate spheroid.

Is it possible to feel the Earth spinning?

Since the Earth rotates at a near-constant speed (that is, it doesn't speed up or slow down in any way noticeable to us), we simply spin with it and don't feel a thing .

Can astronauts see the Earth rotating?

As others have pointed out, you can “see” the spinning of the Earth by watching the stars rotate around a point close to the North Star . The spinning of the Earth also reduces the amount you weigh when you travel to the Equator, due to the centrifugal force of the spin.

What is the furthest sound can travel?

Travelling at the speed of sound ( 766 miles or 1,233 kilometers per hour ), it takes a noise about 4 hours to cover that distance. This is the most distant sound that has ever been heard in recorded history.

How much faster is light than sound?

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 .

How far can you yell?

This question is answered by the Guinness World Records. The normal intelligible outdoor range of the male human voice in still air is 180 m (590 ft 6.6 in) . The silbo, the whistled language of the Spanish-speaking inhabitants of the Canary Island of La Gomera, is intelligible under ideal conditions at 8 km (5 miles).

How fast is the speed of dark?

Darkness travels at the speed of light . More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light. Any time you block out most of the light – for instance, by cupping your hands together – you get darkness.

Why can't you go faster than the speed of light?

So the faster something travels, the more massive it gets, and the more time slows – until you finally reach the speed of light, at which point time stops altogether . And if time stops, well then, so does speed. And so nothing can travel faster than the speed of light.

Is time Travelling possible?

In Summary: Yes, time travel is indeed a real thing . But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second.

What is the circumference of the Earth at the equator?

What is the circumference of Mars?

What is the real shape of the Earth?

The Earth is an irregularly shaped ellipsoid .

While the Earth appears to be round when viewed from the vantage point of space, it is actually closer to an ellipsoid. However, even an ellipsoid does not adequately describe the Earth's unique and ever-changing shape.

Do clouds move or is it the Earth spinning?

Clouds move in response to the local winds. Although the air immediately around you may be still, the winds are far stronger thousands of metres higher up. That is why clouds are usually in motion, even on apparently windless days. But part of a cloud's motion is indeed governed by Earth's rotation .

Why do we not feel the Earth moving?

We do not feel any of this motion because these speeds are constant . The spinning and orbital speeds of Earth stay the same so we do not feel any acceleration or deceleration. You can only feel motion if your speed changes.

How many miles per hour does the Earth spin?

The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second–or roughly 1,000 miles per hour .

Who first saw Earth from space?

It's been 50 years since the Apollo 11 mission took three astronauts — Neil Armstrong, Buzz Aldrin, and Michael Collins — to the moon and back. On July 16, 1969, the day of the launch, the Apollo 11 crew became some of the first people to look down at Earth from space.

Can astronauts see the Sun in space?

Do astronauts see the sun in space? The International Space Station travels at a brisk 17,100 miles per hour. That means it orbits Earth every 90 minutes—so it sees a sunrise every 90 minutes . Thus, every day, the residents of the ISS witness 16 sunrises and 16 sunsets.

What would happen if Earth quit spinning?

At the Equator, the earth's rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward . Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.

What is the loudest thing in the universe?

The 1883 Krakatoa volcano eruption was the loudest sound recorded on Earth, but there are much louder sounds in space, even though we technically can't hear them.

How far could Krakatoa be heard?

Emanating from the island of Krakatoa, which sits between the islands of Java and Sumatra in Indonesia, the sound could be heard clearly almost 5,000 kilometres (3,100 miles) away and by people across 50 different geological locations around the world.

How loud is a black hole?

But that number that is considerably smaller than the energy created by 1,100 decibels of sound. Converting the energy of 1,100 decibels to mass yields 1.113×1080 kg, meaning that the radius of the resulting black hole's event horizon would exceed the diameter of the known universe. Voila!

What happens if an airplane flies faster than the speed of sound?

Anything exceeding the speed of sound creates a “sonic boom “, not just airplanes. An airplane, a bullet, or the tip of a bullwhip can create this effect; they all produce a crack. This pressure change created by the sonic boom can be quite damaging.

Is lightning faster than the speed of light?

While the flashes we see as a result of a lightning strike travel at the speed of light (670,000,000 mph) an actual lightning strike travels at a comparatively gentle 270,000 mph .

How fast is a light year in mph?

In a vacuum, light travels at 670,616,629 mph (1,079,252,849 km/h). To find the distance of a light-year, you multiply this speed by the number of hours in a year (8,766). The result: One light-year equals 5,878,625,370,000 miles (9.5 trillion km).
