EVERYTHING REVOLVES AROUND ONE ANOTHER

If we look at the atoms we see a nucleus and electrons orbiting it. The orbit of the electrons are always under a different angle (see symbol in right angle) but the principle stays the same.

The same can be seen in our solar system. With the Sun as the nucleus and the planets orbiting it. If we look further we see the Galaxies. It looks like the stars orbiting something. Probably a giant black hole in the centre of the galaxy. It's so powerful that it keeps the stars with them. I think the galaxies on their turn maybe orbiting something.

ORBIT OF THE EARTH
This is more a science question.:

I wonder if the following situation could take place: You know that the Earth is orbiting the Sun. You also know that the Moon is orbiting the Earth. The Moon is in relation to the Earth a big object, if you compare it with the other moons of the other planets. When the Moon is orbiting the Earth, would the Moon slightly 'pull' the Earth towards it? As a result, would the distance between Sun and Earth be smaller when the Moon is between the Sun and the Earth. And bigger when the Earth is between the Sun and the Moon.

In other words, does the orbiting of the Moon influence the orbiting of the Earth around the Sun? It will all be minimum. You probably want to say to me: "Who cares!". But still, it's my question.

DUST LAYER AROUND COMET

This is my thought about dust around the comet.
The orbit of a comet is elliptical. (See fig. 1) The comet is sometimes very close and sometimes very far away from the Sun.

If the comet is far away from the Sun, the surface temperature is so low, it reached the absolute zero point. There is no attraction between atoms any more. The material collapsed. But there is no other force to separate them. The atoms stay together. This is probably true for the exterior alone. From the inside there is enough energy to stay a 'material'.
Note: this is my speculation.

You may think: "What about the objects in the Kuiper Belt and Oort Clouwd. Don't they collapse?"
I have no explanation for that. Maybe not the hole object collapsed.

When the comet reaches its farthest point, the Sun 'our star' is still the nearest object. Proxima Centauri is the next star, but is yet too far away to influence the comet. (Unless it reached too far into the Oort cloud. Such cloud of another star may overlap.) So the comet is on its way back to the Sun.

Probably the atoms can't vibrate without the radiation energy of a star. Because when the comet gets closer to the Sun, the atoms start to vibrate again and it becomes matter again. Due to the fact that they went through the 'zero Kelvin' phase. They form a dust layer around the comet. The particles variate from size. Some particles combine to a size of few micrometer. others stay with the size of a molecule. When the comet gets closer to the Sun, The lightest particles will disappear first. That's why Rosetta did not find very small particles.
These are also my thoughts about it!

Every time the comet passes the Sun, it loses material. It gets smaller and eventually it explodes into dust. And is blown away by the suns radiation. With this in mind there might have been more comets in the past. I'm not a scientist, but I like to think about those things.

TIME

Time is a strange phenomenon. Sometimes it takes awfully long and sometimes it flies away. You will discover that when you get older, time goes faster. I'll try to show you in a formula&. (See fig. 2)

Emotional time:
Time as you experience it, how the brains process it.

Absolute time:
The real time.

Activity:
What you are doing at the moment. That could be physically or mentally. E.g. physical work or a puzzle.

Age: Your current age.

Below you see how the formula is build:

   absolute time = emotional time + activity

If you are busy then time seems to fly away. If your not busy, you look at the clock, one minute feels like an hour.

We turn the formula around:

   emotional time = absolute time – activity

Maybe you can remember when you were a child, that it took ages to your next birthday. That elementary school seems to last for ages. So many days before Christmas. And maybe now you think: "Is it my birthday again? Can't we skip it for a year?" It looks like when we get older, time seems to go faster. If we put the age in it, you will get the formula you see above. "In the white area."

All this is not scientifically based. I find it interesting to see that time can also be a sense. And when you get older, it seemed to go faster.

TIME TRAVALLING

Long time ago men wanted to fly. In those days it seems impossible. After many attempt we eventually succeeded. Now flying is very obvious. Then there was a dream to go further in the sky. Maybe the Moon? Also that seemed to be impossible (There are still people who won"t believe it.) but we did it again!

Now there are plans to go to Mars. Then we are trying to colonise the planet. There are many movies made about time travelling. Now we think it's impossible, but who knows it might be possible in future. I thought about it and these are my thoughts about time travelling:

Time that's running now, can be imagined as al strait line through a time spiral.
(See fig. 3)

If you go back in time, you change history a bit. Because you suddenly appear somewhere. The people see you and you may have a conversation. Things will be written down what men has experienced.

In addition, the following may occur:
Our body doesn't have to make antibodies for diseases that extinct. If you go back in time, you meet them again. you could get ill. And what if you met yourself?

If you want to go back to your own time, you can never go back to the point were you started. The red line indicates that. You arrive at a parallel world with the changes you made. To us nothing changes. The one who makes the time travel is gone and we will never see him back. Because he lives on in the present he created.

Sounds like a fantasy, and I hope it stays that way for a while. Future travel seems unlikely, but you never know. If time travelling will ever be possible? Time will tell.

ESCAPED STARS

The universe consists of billions of galaxies. What's between them?

I have my thoughts about it:
Galaxies often have a Black hole in the center. Black holes have an enormous gravity. I think the gravity of the black hole keeps the stars together. As I said in 'Everything revolves around one another'. It looks like if all the stars are revolving around the black hole. The stars at the end of the galaxy are so far away from the black hole at the center, they escape from the galaxy. That could be stars on their own. But also stars with planets. On those planets could be 'life'. If that's so, the search for extraterrestrial life will become more complicated.

CROP CIRCLES

Crop circles, you sometimes see them in fields. They are more visible with a helicopter or drone. But how are they made and by whom? I've been thinking about that again.

I think it goes like this:
A drawing is made in advance of what it will look like. People go into the field and begin to drill a long iron 'herring' into the ground. The herring has a handle so that it is also easy to remove. A sturdy rope is attached to the herring, on that rope there are colored tape in various places. You hold the rope with the right color and walk in circles, until a round surface is created. The first crop circle.

Then with the rope, and the tape, the distance is determined for the center of the of the next circle. At that point the herring is brought back into the ground. Now the rope is held in a different place. Repeat this a few times until you have made a whole pattern. You can use a protractor or compass. It must of course be done at night, so bring a flashlight.

An example:
Of course I don't know exactly how you make crop circles, maybe it is made this way. Don't try it out, otherwise you will argue with the farmer.

We are going to make the pattern of a mouse. Enter the field somewhere. Drill the herring into the ground. Attach the rope to the herring. First length, three meters. (10 feet) (See Fig. 4.) Indicated with a specific color of tape. Walk a few circles until it is flat.

Take your compass and stretch the rope 40 degrees west, we are now going to make the left ear. At the second length, four meters, (13 feet) stop the second herring in the ground. This is the center of the left ear. Untie the rope from the first peg and attach it to the second peg. Mark the first herring so that you can find it in the dark.

Then you go to the third length, one and a half meters, (5 feet) and walk around again until it is flat. Reattach the rope to the first peg. Then go east 40 degrees for the right ear. There you repeat the same as the left ear. And your mouse is ready.

So if you see a crop circle, look for the hole that the herring was in. If you don't find a hole or something and you still think it has something to do with Aliens, call M.I.B. :)
