When I first saw the light it did not seem to moving I had no idea what it was. Venus maybe? Then I saw it actually was moving, so I thought it might be the International Space Stations, which had made a couple of good passes over here in the last two days. I tried to take some photos, and got some blurs like the above. I switched to video and what I saw on the view screen was a strange set of three flowering lights. When I put it on the computer though, it looked like this:
It's a plane of course, and I realised that as it approached me and flew overhead. Lufthansa 459, from San Francisco to Munich. An A340, climbing through 20,000 feet. My first photo was just a pretty piece of motion blur from the camera moving. The...
A classic experiment to demonstrate the curvature of a body of water is to place markers (like flags) a fixed distance above the water in a straight line, and then view them along that line in a telescope. If the water surface is flat then the markers will appear also in a straight line. If the surface of the water is curved (as it is here on Earth) then the markers in the middle will appear higher than the markers at the ends. Here's a highly exaggerated diagram of the effect by Alfred Russel Wallace in 1870:
This is a difficult experiment to do as you need a few miles for the curvature to be apparent. You also need the markers to be quite high above the...
A misleading headline is making people think that a physical object has been teleported from the ground into space, leading to all kinds of excitement and speculation about Star Trek style teleporters.
In fact nothing like that has happened at all, if you actually listen to the BBC piece, you'll find that what has been transmitted is just information. Nothing physical has moved from the ground into space.
There's a similarly misleading story from MIT's Technology Review.
The above image appears to show three different metal rods. The left rod is short and straight. The middle rod seems longer and angles sharply to the right. The right rod appears slightly curved, and has a longer segment going off the edge of the photo.
Actually the rods look like this:
Despite the left rod looking like it's just a few inches, it's actually five feet long. And even though the right rod looks like it's bent very close to the end it's actually bent in the middle, as is the center rod.
I set this up to illustrate some of the problems in visualizing both contrails and the paths of planes that don't leave contrails, especially those that are far away, and so at a shallow angle to the viewer.
In particular, look at the...
Something that has recently been presented as evidence of faking the space program, or even of a "Flat Earth" is the occasional discovery of what looks like a crashed satellite, but one that has more gracefully descended to Earth on a balloon. One such example is the video "Satellite crashes in Brazil - attached to a balloon - Nasa lies, research Flat Earth"
The mystery is quite easily solved just by reading the blue and white sheet of paper in a ziploc bag attached to the side of the "satellite" (which actually landed on May 15, 2017)

A variety of images reported as "UFO"zm show what looks like a glowing disk with some dots on it. These basically look like lens flares, but the dot patterns are unusual, as they vary from irregular, regular, or or semiregular patterns. However they still look very two dimensional - they don't seem to curve around the "orb". Here's a collection of similar images all claimed as "UFOs"
What we are seeing here is a reflected image of the sun with the highlighted reflections of focus pixel. ...
In the recently published paper Improving Climate Change Acceptance Among U.S. Conservatives Through Value-Based Message Targeting, (Dixon, et al, 2017) the authors describe the problem of communicating established science regarding climate change to a conservative demographic.

The horizon is visual line that separates the earth from the sky. On land this is usually nearby hills and is quite uneven, but if you have a good view of the ocean the horizon appears as an essentially flat line between the sea and the sky.

It looks flat, and in fact the horizon IS geometrically flat. Since all the points on the ocean horizon are the same distance away from you, and the same distance below you, the horizon forms a flat circle with its center some...
A documentary from Gaia.com claims that what looks like a mummified corpse is evidence of a new species, possibly of extraterrestrial origin.
Now several red flags pop up. Most immediately that Gaia.com has a history of creating videos promoting the idea of ancient aliens, none of which panned out into actual evidence.
But what of the mummy itself? It's claimed that it was found in the Nazca region of Peru. This makes some sense as similar human mummies have been found in the region (which is very dry, and so bodies protected from the elements are naturally preserved by drying out).
