Im bored. I just did my maths homework and I am typing this new post. I really do forget to write on this blog. Can you tell me who is still doing their blog?

# Bog info

I’ve made a science blog!

Here it is. Im still working on it.

# Hello

Your right I have lost count of the hello’s any way The time is now 8.28 am saturday and im bored so im righting some posts. i have been randomly searching quantum phisics and I have had a idea. Ive played a game and its about placineg portals, so i thought why not to make a way to do a real portal? Youl see the reasults when Im finished.

Antil then……

I dont know what to put after antil then, please give me an idea.

I have forggot to port again! How many months was that.

Hello and ive been reasherching gravity energy ive found this on the web hope it helps!

Gravity/Energy Paradox

To illustrate a paradox that occurs in both Newton’s and Einstein’s theories of gravitation, let’s consider a simple thought experiment in which Max drops two identical, one kilogram metal balls from different points on a building.

Max drops the first ball from the top of the building, then runs down to the next floor and drops the second ball from a point 5 meters lower than the first, exactly one second later. At the instant that Max releases the second ball, both will be at exactly the same height above the ground. At this point in time, the first ball will have a velocity of approximately 10 meters per second (10m/s) and a kinetic energy of 50 joules. The second ball will have zero velocity and zero kinetic energy. Then at the end of the 2nd second Max catches both balls to measure their velocity and kinetic energy. He finds that the first ball has a velocity of 20m/s and a kinetic energy of 200 joules, and that the second ball has a velocity of 10m/s and a kinetic energy of 50 joules.

The paradox here is that these two identical balls each acquired greatly differing amounts of energy in the same last second of fall. If gravity is an attraction between the earth and the balls, in which kinetic energy is constantly being added to the falling balls, then how is it possible for the earth to add three times as much energy to the first ball as the second ball even though both balls began their last second of fall at exactly the same distance from the earth? How does the earth “know” that it must apply 3 times as much energy to the first ball as it does to the second ball during the same one second interval? How is it possible that the magnitude and the direction of a body’s motion can have such a large effect on the amount of energy that the earth’s gravity exerts on that body?
