Warm Arctic?

Posted on Posted in Memories, UncategorizedTagged , , , , , , , , , , Leave a comment

I just read a post from a flat earther on a flat earth page asking why people can stand outside in the sunshine with just a tee shirt or hoodie on? I tried to answer.     

   Arctic and Antarctic summers happen at opposite ends of the year. In the North it’s around June/July and in the South it’s December /January. In the summers the temperature can rise well above zero, because in the summer months the sun doesn’t set (in the winter months it stays dark for several weeks), hence, yes people can wear hoodies and tee shirts. It’s getting warmer because of global warming and it means sea ice takes longer to form. In addition the temperature rises at the poles are happening more strongly than at other parts of the globe.    

I hope this makes sense.

Arguments against a flat earth theory.

I keep seeing posts on Facebook about the earth being flat. So I thought for a few minutes and posted this…. . If the earth was flat the sun would set AT THE SAME TIME EVERYWHERE. There would be no time zones. New years eve would be celebrated at the same time everywhere. Clocks would all be set to the same time. If you live in a big country like America the sun would rise and set at the same time, so you wouldn’t need Eastern standard time and pacific time or whatever it’s called. THERE WOULD BE NO SEASONS, AND THE TEMPERATURE WOULD BE THE SAME ALL OVER THE WORLD. If the Earth is a globe and tipped you get seasons. If it’s a globe and not tipped, no seasons, flat earth? No seasons, no gradient in temperature. And the sun would rise and set at exactly the same time every day… Sorry rant over.

The Earth is a sphere!

What’s something you believe everyone should know.

A look at the Earth from space, the North American continent is fully visible, but the South American continent follows the curve of the Earth around to the other side. Also note the left side is darker as the Earth rotates into darkness.

Question. If Earth was flat where are the other continents hiding? Why isn’t the whole planet in full sunshine? Why is the shadow the Earth casts on the moon always round? (which gives us the moons phases). If Earth was flat the shadow would sometimes be a line. Why is every planet a sphere but not Earth?

Occam’s razor says that usually the simplest explanation is the truth.

From Wikipedia :

In philosophy, Occam’s razor (also spelled Ockham’s razor or Ocham’s razor; Latin: novacula Occami) is the problem-solving principle that recommends searching for explanations constructed with the smallest possible set of elements. It is also known as the principle of parsimony or the law of parsimony (Latin: lex parsimoniae). Attributed to William of Ockham, a 14th-century English philosopher and theologian, it is frequently cited as Entia non sunt multiplicanda praeter necessitatem, which translates as “Entities must not be multiplied beyond necessity”,[1][2] although Occam never used these exact words. Popularly, the principle is sometimes inaccurately[3] paraphrased as “The simplest explanation is usually the best one.”[4]

Happy New Year!

Because the world is a globe some people on the international date line will have celebrated New Years day about ten hours ago. It also makes sense that the world is round because it gives Santa twenty four hours of night to get round the world instead of twelve if the Earth was flat (think about it!)….

I want to wish you all a Very Happy New Year. May 2023 be better for you, better for your family and friends and better for the planet too. X

Stay safe and well. X

Earth rise?

I made this image using a blow up globe and a bath towel..

Trying to replicate the globe rising over the limb of the moon. But obviously our world doesn’t have latitude or longitude printed on it! And we don’t have different countries coloured in to indicate where there bordered are. I wonder how flat earth believers react to the real image. Do they think the other half of the world is on the back? If it was flat the sun wouldn’t rise slowly but it would illuminate half of the world straight away (unless you are behind a mountain) then after twelve hours set immediately. One side of the world would be in daytime at the same time, the other night time. Get rid of most time zones! Only two needed, twelve hours separating them. Plus you’d notice crossing the edge! And no seasons, so no equatorial heat or Arctic and antarctic regions! And where does the edge fall and wouldn’t the international space station notice?

Thinking… Its good to try it out!

How to tell the earth is a sphere…

So how can you tell the Earth is a sphere? The ancient Greeks worked it out ( I don’t remember the name of the person who did).

The experiment was to put a stick in the sand at or near the equator, so it would have a tiny shadow directly underneath the it at mid day as the Sun was directly overhead.

If you place a stick upright, at 90° to the Eaths surface either North or South of the equator, the stick casts a shadow at mid day. (Look at the hands of a clock the hands move round in the same way). Say the equator is 3pm and the Sun is overhead, you would get no shadow, then as you go further away from the stick at the equator you get increasing angles (see diagram). Eventually at the poles the shadows would be at their longest.

So how can you tell its a sphere? The angles add up. You can calculate the curvature of the planet from these simple experiments. The ancient Greeks got very close to calculating the circumference of the Earth. Their calculations were only a small percentage out on their measurement.
