60 Anyone can prove the sea-horizon perfectly straight and the entire Earth perfectly flat using nothing more than a level tripods and a wooden plank. Straight line travel 100 Proofs that the Earth is a Globe 23.
How Many Miles Around The Earth Facts Land Area Surface Area
The longest straight-line sailable path on Earth.
. A new record has been discovered. Geometry tells us that the distance of the horizon ie. This area is also called the equator If you estimate that a day.
The Earths diameter is also wider at the Equator creating a phenomenon called an equatorial bulge. Calculating the obstructed height of an object Look at the image above. Straight line travel Travel in a straight line across the surface of the Earth in any direction.
Draw a circle on the map with the radius of your choice to visualize these restrictions directly on the map. The Earth is widest at its Equator. After approximately 40000 kilometres you will find you are back where you.
Calculation of Deviation from Horizontal. At any altitude above sea-level simply fix a 6-12 foot long. The farthest point the eye can see before Earth curves out beneath our view depends simply on the height of the observer.
1 where R is the radius of the Earth 39632 miles x is the horizontal distance of interest 100 ft Conclusion. Put another wayGR can show that the earth is not orbiting the sun rather the earth is travelling a straight path and spacetime is wrappedcurved around the sun. This tool enables you to calculate the straight line distance between two locations or two cities as the crow flies.
Here is a quick drawing of it that we did on a map. Ive also focused considerable attention on the Canada-United States border. Here is a video of that.
In Appendix A I give examples of the computations in Mathcad. You can try to derive it yourself it is not that hard. It represents a situation analogical to the one with the ship from above.
The search confirmed the Redditors original assertion finding that the longest-straight path on Earth without hitting land measures 320897 kilometers or about 19940 miles. R Earths radius equal to 3959 miles or 6371 km. But at 7 inches tall you wouldnt see it.
The Earth curves 8 in per mile. It is nearly 22229 miles long. The default radius on page load is 100 km.
That one hugs the 49th degree of latitude north for something like 2000 km 1250 mi although we know its really composed of hundreds of smaller segments. It depends on your definition of a straight line. As the distance varies depending on the location you can set the specific radius applicable to your situation in the corresponding field.
Examples of covid-19 restrictions currently applied or. So gravity space-time curvature. The circumference distance around the largest part of the Earth is roughly 24898 miles 40070 kilometers according to NASA.
If however you mean in one direction without hitting land. It looks like the vapour or Chem. This equation can be derived using the Pythagorean theorem.
Given the situation shown in Figure 1 we can compute the deviation from horizontal as follows. Here are the steps to use it. Einsteins general relativity says that all the planets and our earth actually travel in a straight line within a curved space-time.
As the world and thus the sea is curved you cannot travel any distance in a straight line. But there is at least one ocean path thats likely never been traveled. So if your 8 inches tall and the ground is level like it is in the salt flat deserts of Nevada and Utah youd be about to see a flashlight laying on the ground at 1 mile.
You can sail from eastern Canada all the way around the world to western Canada in a straight. The distance around the Earth at the Equator its circumference is 40075 kilometers 24901 miles. Anyway during one of his searches Tyler come across this weird straight line spanning around 13000 miles - from the tip of the Antarctica to the North Pole.
1 The horizon always appears perfectly flat 360 degrees around the observer regardless of altitude. It ran an amazing 478 kilometres 297 miles in Australias Longest Straight Line. The diameter of a circle is measured by a straight line that passes through the center of the circle and.
The longest straight line over the ocean without touching land. Supporting Flat Earth Proofs. If you are six feet tall you can see the flashlight on the ground at 301 miles away.
There is a route from the southern Asia to South America which is just over 20000 Km or half the earths circumference See Google earth. Enter the address or the city of the first location. As you can share your location it will let you know easily how far you are in a straight line from any point of interest.
The Earth is just under 8000 miles in diameter so a line from ones present location through the center of the Earth to a point on the surface directly opposite would be just under 8000 miles.
