the earths radius is 6378km. the average continental crust is about 35km deep. even at that depth temperature in 150degrees celsius and the deepest that man traveled is anywhere between 9-13km . apart from temperature man would face many more obstacles in a journey to the centre of the. pressure, harmful gases, lava all pose formidable challenges in this journey.

If the earth were a mile closer to the sun how would it affect our temperature on earth? How far would the earth have to be from it's current orbit to notice a temperature change?
The average surface temperature of the Earth as a result of it bathed by sunlight can be calculated by assuming that both the Earth and the Sun are blackbodies and...

A certain quasar recedes from Earth at 0.55 c. A jet of material ejected from the quasar toward the Earth moves at 0.13 c relative to the quasar. How do you find the speed of the ejected material relative to Earth?
Suppose if $v$ is the relative velocity between two frames $X$ (earth) and $X'$ (quasar). The relative velocity of an object in the two frames are related to each other...

What would happen if you brought a piece of the center of the sun the size of a basketball back to earth? What would happen to the living things around it, and if you dropped it, would it burn through the ground into the earth?
Take a look at a wiki article on the .

What is keeping the Earth's degree of tilt in its orbit around the Sun and why doesn't the Earth wobble? When was the last time the Earth's degree of tilt changed?
The Earth's tilt axis , or obliquity, is changing continuously over a 41,000 year cycle. The angle of tilt varies between 22.1 and 24.5 degrees. It is currently at 23.44...

What is Earth's diameter size in Astronomical Units? What is the best unit for Earth? Also, what is Earth's size in light-year?
IAU (International Astronomical Union) AU = 149597870.7 km. 1 light year (LY) = 6.29 E+04 AU. For the precision in measurements of angles, all the significant digits (sd) in size...

How has the earth's core stayed so hot for so long? When will it cool down?
Let it be hot inside. .Earthians are really fortunate. In contrast, the star Sun's core energy is transported by radiation, through radiation zone, and then by convection (by rolling...

If you take millions of tons of metal off the earth in the form of satellites therefore reducing earth's specific mass, would this in turn affect the earth's orbit around the sun?
Our estimates are from scientific computation. The precision (the number of correct significant digits (sd), in scientific notation) cannot be more than the smallest among the sd in the...

What is the distance from the Earth's center to a point in space where the gravitational acceleration due to the Earth is 1/24 of its value at the Earth's surface?
The radius of the Earth is approximately $4000$ miles. Gravity obeys an inverse square law, decreasing by the square of the distance from the centre. So the gravitational acceleration due...

Hot compresses for a patient are prepared with water heated to 145°F. What is the temperature of the hot water in degrees Celsius?
$°C = (°F - 32) × 5/9$ $°C = (145 °F - 32) × 5/9$ $°C = 113 × 5/9$ $°C = 113 × 0.55555555555555555555555555555556$ $°C = 62.7$

Which gas did Jacques Charles discover could be used as the source of hot air for a hot air balloon's envelope?
According to this M. Charles used the action of sulfuric acid on iron filings to fill his bladders: $Fe(s) + H_2SO_4(aq) rarr H_2(g) + FeSO_4(aq)$. Charles was a contemporary of...
