If you could dig a tunnel to the center of the earth how long would the tunnel be?
First, it would not be a tunnel because tunnels basically go along sideways rather then down, it would be a well. The radius of the Earth is 6,371 km and this is how deep the well would be.
The idea that earth was the center of the universe is an example of that has long been discarded?
the answer is a hypothesis
A long time ago people believed that the - blank - was the center of the universe?
Earth
Why would it take long for alpha centauri light to reach earth?
along long long long time
How long would it take to ride a bike around the earth?
It cannot be done. To ride a bike around the earth, the continents would need to be connected, or the bike would need a really long bridge across the ocean.
How long does is it take to go to the center of the earth?
It would take 120 years to go to the center of earth
How deep would you drill to reach the center of the earth?
If you to dig one foot per minute, then it would take six years to get the center of the earth. INCORRECT. The Earth's diameter is approx 8,000 miles, making the radius (distance to the center of the sphere) approx 4000 miles. A mile is 5,280 ft, and 4,000 of those = 21,120,000 ft. If you could dig one foot per minute, as stated by the previous answer above, then there are 525,600 minutes in a year. Now, divide the amount of total feet (21,120,000) by the number of feet per year (525,600) to get how long it would take to dig to the center of the earth, which is a little over 40 years. that's how long it would take. 40 YEARS. If someone fell into a hole and was in a free fall all the way down, it would take over 30 hours to free fall to the center of the earth. "If someone fell into a hole and was in a free fall all the way down, it would take over 30 hours to free fall to the center of the earth." INCORRECT. I'm pretty sure you forgot to calculate the increase in gravity as you travel closer to the core
How long will it take to drill through the crust?
Currently we cannot drill to the center of the Earth because no drill could withstand the temperatures in Earth's interior. The deepest hole ever drilled reached a depth of 12,262 meters (40,230 ft) or about 7.6 miles before it stopped working properly due to the heat. Earth has a radius of nearly 4,000 miles. Even if we had a drill that could withstand the temperatures of Earth's core, the outer core is liquid and features active convection currents.
If a magnetic item was in the center of the earth would it float?
It probably would have melted long before it got there.
How are ores near earths surfaces removed?
ores near earth's surface are removed by underground mining as long as they don't cause the mine to collapse as they drill.
How long would a sudden light burst from the galaxy center take to reach earth?
25,000 years.
Can you use a drill bit to measure a kilometer?
No, a drill bit is quite small and also not a measuring tool. A kilometer is quite a long distance and would be as long as around 10,000 average drill bits.
If you cycle at 20 km an hour , how long will it take You to cycle to the center of the earth?
I myself cannot cycle to the center of the earth.
How long does it take to get to the center of the earth from the surface?
Depends on your speed.
If you could dig a tunnel to the center of the earth how long would the tunnel be?

How long would it take to travel to the center of the earth?
42 minsz from one place to another 42 minsz from one place to another
What keeps the center of the Earth warm?
Earth's core is warmed by the slow decay of long lived isotopes.
