Up there, within our own Solar system (and beyond) everything is in motion. There is no space object that is standing still. Ever since the big bang. Even the black holes that are capturing things into singularity point are moving across the universe along with their own neighborhood. The same is with Earth and its first neighbor Mars. They are both orbiting the Sun in their own time schedule - Earth needs full year to complete the cycle, while Mars in its own distant orbit needs 322 more days to do it. While both, Earth and Mars travel around the Sun, sometimes they got closer to each other by the approximate 55 million kilometers (while the farthest distance between the two is about 400 million kilometers).

More and more I found myself troubled by following worldwide news on daily basis. It's not that I have lack of free time to filter them all out. More, it is that recently I started feeling certain reluctance reading the headlines filled with conflicts, wars and civil fights, religious and cultural animosities, political and all the other disgusting affairs, political elections full of poorly casted actors, stories that you have to use superb power to read them between the lines, worldwide armed conflicts and warfare in foreign countries that I have not the slightest clue what initiated them all and why, mediocre journalism and sensationalism in the worst meaning of the word, etc... The list is endless and believe me I'm not even referring to all those black chronicle stories with unappropriated articles where i.e. somebody killed his parents with an ax or mass murder of cinema crowd by a lunatic in batman suit or worse. Or in today's case and what inspired me to revive this...

One day build of Lego Ideas: International Space Station. For over 20 years, the International Space Station has welcomed cooperation from different nations to achieve common goals that benefit all mankind. The largest spacecraft ever built, it continues to unlock discoveries not possible on Earth—and push the boundaries of human space exploration further than ever before.

The 'X' is definitely one of the most important letters in the alphabet. Not only that it is the most valuable variable in all math equations and scientific chase for the unknown, but in the entire history of human riddles, and I mean not always related to math, it always marks the most interesting spot. Sometimes the one with the treasure. It was not coincidence that old Romans used it for the most important number of them all. 10. The very base of our widely used numeric system. But we are not here to talk about mathematics or treasure hunting per se. It will be more about age. Of ten. My son Viktor is turning this magic number on this year Earth Day (April 22nd) and I decided, in addition to our previous topic and post Interview With an Expert , to fire another set of questions for him to answer. This time more general and within various realm of life and .. well .. stuff... So let's start with favorites. I guess they say a lot about personality. And they don...

Sometimes I think we are just like ants. Too small and with lifespan too short to make a valuable difference. Our civilization I mean. After reading another book or watching another movie or documentary it's difficult not to notice that there are far too many 'apocalyptic scenarios' capable to put 'the end' sign in the thin air. Far too many boots to step on our little fragile anthill. This november thanks to Matthew Mather, one of the definitely greatest stars of the Earth's science fiction realm, I am 'proud' to announce two more ways of how to kill the Earth. Two more latest addition to this blog Post-Apocalyptic thread. Black hole and Sun direct collision with Earth close by I know you are now wondering about this above image and already expressed couple of frowns and disbelief looks, but before diving into rogue black holes, let's first glimpse the first scenario from the title. If nothing else, then just to ease things a little bit and...

Don't take this title too seriously. It's wrong on multiple levels. Grammatically and scientifically. Nonetheless it fits perfectly for this post. As for grammar amiss - I used Latin root word 'Gravis' which means heavy and it is actually perfect adjective for gravity as we perceive it here on Earth. As for scientific issue, the rest of the title might be all wrong. If we glimpse into features of three main natural forces of the universe, it is obvious that they work in more or less the same fashion - they use carriers or elementary particles to mediate the force through the force field. Photon is one of them and it carries electromagnetism while strong and weak force in nucleus respectively are mediated by gluons and w/z bosons and they are all confirmed in experiments. Gravitons suppose to be the same thing for gravitation force, but they are never found and confirmed either directly or consequently. Ever since Einstein we are having second thoughts about whether or ...

Do you know how big is our Solar system? I can't be sure of course, but there's a strong possibility that common knowledge about our planetary neighborhood ends with enumerating most of the planets, one dwarf planet and couple of named moons, asteroids and comets. Amazingly, the truth is far, far beyond that and believe it or not, if we include Oort cloud, the Solar system, with us representing its only living residents, is approximately 3 light years in diameter. This is, more or less, equal to 3e+13 kilometers or 30.000.000.000.000 km. The distance about 100 million times bigger than the distance to the Moon. It is tremendously huge and just about one and a half light years shorter than the distance from our Sun to the nearest star! The layout of the solar system*

Just like a single ant who's lost in the large expanse of Brazilian Casino Beach ( Praia do Cassino , 250km in length, considered to be the largest beach on Earth), and felt as small as possible in surrounding space, we humans are experiencing similar sensation when it comes to space and especially time. But, contrary to ants, we have the ultimate tool, called science, that is allowing us to see beyond the horizon. If we could place ourselves in ant's shoes, we would find clues and evidence all around us and, metaphorically speaking, no matter of large quantities of sand grains, we would know that we were on the beach. And with time, when it comes to history of life, all the clues lie in fossil records of coral reefs. The main study, performed by J.E.N. Veron in his publication " A Reef in Time ", identified five periods in Earth's history with major extinction of corals that built reefs. In all five periods, fossil records of the reefs needed millions of ...

Did you know that if you were standing on the near side of the Moon, and for your mass of 80kg and weight of 785N on Earth, due to Moon's lower gravity, you would not feel being heavier than 13kg (130N)? You knew? Ok, did you know that Earth's and Moon's gravities combined gave you different weight on near and far side of the Moon? Slightly yes, but true. Earth and Moon are relatively small celestial bodies but this difference goes even higher if you move from the Moon to the Io or Europe for example as they are also tidally locked by Jupiter just like our Moon is locked by Earth. This would most definitely not help mountains on Avatar's Pandora to float but still, within right conditions and with presence of large mass(es) nearby, considering appropriate composition of the ground I am sure there are solar systems out there with strange conditions to live with, to say the least.

Do you remember United Nations? The worldwide organisation created just after the sunset of World War Two with mainly one goal - to prevent global warfare in the future and to deal with our planet outside the boundaries of it's members? United Nations Security Council* Yes, it still exists, somewhere on the island of Manhattan, with its powerless debates and Security Council decisions without much responsibilities for those who signed them as well as for those affected in any way. Sadly, the power of global government never actually made to UN, despite all the good efforts throughout the years and it always staid with those in individual countries, or groups of them, either politically or geographically or ideologically divided. The truth is that there was no big decision in the history of the mankind, either good or bad, that is made by some mutual organisation of any kind. Those are all made by either one man alone in some sort of dictatorship, or by a small group of li...

What do you think is THE fastest thing on Earth and beyond? I am sure if you first thought of a heavy rocket capable of taking astronauts to the orbit in less than 2 minutes or the fastest spacecraft we ever built with its speed of almost 90000 miles per hour, the answer would easily be NO. Comparing to what I am referring to right now, all those great man made machines are traveling only little faster than snails. Not even the motion of a planet or a star is even close to the speed of .... one little thing traveling as fast as human thought ... and simply called ... TIME. The time is the only thing that travels so fast that sometimes it seems that some memorable event engraved in our memory banks years ago, looks so vivid in the present like it happened only yesterday. If we look our children and how rapidly they grow, or ourselves, for that matter, caught on some picture in the past we simply can't get rid of the feeling and obvious question of how on Earth, time passed that ...

There is no doubt that this comparison or question if you will is as old as humanity itself. Perhaps the basic idea of invisible forces driving human beings and everything around started to occupy human mind ever since it evolved beyond simple survival or in those prehistorical times when our ancestors started thinking about things not always related to eating, sleeping and populating the planet. It definitely originated way back in the time when people started to paint the cave walls. In the time when human mind started to use the most powerful feature other species still waiting to emerge. The power of imagination. The birth of superstition and religion didn't wait much longer after humans started daydreaming. What did I do?* I am always getting back and reading lots of articles out there trying to find the best explanation of what is the main difference between superstition and religion. There are lots of philosopher's, religious or even scientific thoughts trying to...

I have an old friend who couple of years ago made a decision to radically change his way of life. What he did is almost unreal for the rest of us. He simply stopped eating food we are all familiar with and instead he eats only fruits, vegetables and various grains and nuts. All that in its raw and natural form without any cooking, baking or frying. Of course as a practical man (he is a math teacher in my wife's school) he didn't do this over night and instead used methodical approach so his switch from "ordinary" food to this final stage of the most strict vegetarian diet possible lasted couple of years in order to adapt his organism better and to avoid potential dangers on the way. Contrary to other vegetarians I know he didn't do this because of some illness or because his organism is not capable of digesting meat and thermally processed food. Instead this was an act of free will and strong belief that he is doing a good thing. I strongly admire him for this and...
