Were previously cheated! Earth's true colors are so
When it comes to the color of the earth, we always think of the network that a picture or documentary dazzling blue. Unfortunately, the real situation does not seem so.
Recently, Japan's meteorological satellites transmit sunflower on the 8th planet a group photo of the latest shooting ground, which is said to Earth the most natural color. We get the impression that beautiful blue planet, in fact, after the color modification processing.
Earth's "character" than many of our bleak impression of the blue planet, but also very beautiful. In this tone, red chunk of western and central Australia is very conspicuous. It is reported that these images are a sunflower on the 8th meteorological satellite in the Earth at a distance of about 35,800 km of shooting.
Earth does not seem to us the impression that the United States, but this does not affect its image in the minds of human beings, after all, this is our existence homes ah.

The Hubble telescope has been off for over 20 years
The figure is a quality in a small galaxy Hubble discovered in 2000 times the sun's black hole.In contrast, the center of our Milky Way black hole mass 200 times the mass of the sun, but also.
This is the latest Hubble telescope pictures of Jupiter. Photos of the "big eyes" on Ganymede is the shadow of Jupiter, around the Great Red Spot is also clearly visible. The recent signs of narrowing the Great Red Spot appears.
This is a strange gravitational lensing photos, looks like two central celestial pearl is actually the result of the interaction of cosmic objects, and long chain of celestial bodies is the result of galaxy interactions and mergers.
This photo record away from our galaxy M82 close supernova. Supernova is a product of stellar death.
It is formed in the dust disk around a star exoplanet, and the evolution of our solar system's planetary system is the same.
Seyfert galaxies in the universe is very characteristic of the galaxy, was a beautiful spiral structure, lies about 32 million light-years away, scientists believe that the existence of this galaxy central supermassive black hole, it will appear bright central nuclear energy activity traces.
This picture looks like a dark cloud of terror when the weather changes, but in fact this is the case of the early universe, star birth, and filled with a variety of stars.
Hubble Ultra Deep Field for showing us the magnificent and vast universe. 2014, again on the distant universe Hubble deep space observations, reminding us on the road to explore the universe is still in its early state.

Seven Unbelievable Scientific Idea:
according to foreign media reports, isn\'t terribly far-flung from you feeling science, suppose science is incredibly boring? however in truth, in our lives to own lots of attention-grabbing scientific plan, however we tend to aren\'t able to be realised in lifestyle, what number of those ideas would possibly even feel a trifle crazy. as an example, we tend to could also be living during a virtual \"parent\" of the globe, and then, or, within the high floor of a tall building time goes quicker.
Following on such lists seven scientific idea:
Time Space Station more slowly
this can be not theory, however arduous scientific facts. Gravity can create time to weigh down, thus once the field of force strength weakened, the time are accelerated. Here you\'ll most likely say: \"No, so to say, time isn\'t on the station ought to go faster?\"
Yes, however additionally think about alternative aspects. ISS is 17,000 miles per hour (about twenty seven,000 kilometers) per hour period dilation impact at such a high speed owing to the space platform that overshadowed the area atmosphere caused by the weak attraction acceleration time effects.
when returning to the bottom though this impact is negligible, however the astronauts spent the mandate amount of six months on the station, they need been but the folks on the bottom regarding zero.007 seconds. If higher craft in operation speeds, then now distinction can become additional important.
we tend to ar nearly definitely being during a virtual \"parent\" among
British thinker Nick Bostrom (Nick Bostrom) thought we tend to might board the same \"Matrix\" as a virtual \"mother\" reception.
thus say a basis? With technology development, the pc can eventually become sturdy enough to love \"The Matrix\" is delineate as making a virtual world - that live consciously, with the knowledge of the humanity.
folks living during this virtual world can still create progress, till the day that their technology is additionally able to produce such a virtual \"parent\" of the globe. Thus, the \"mother\" can seem within the infinite multilayer virtual world. we tend to ar doubtless to measure in such a virtual \"parent\", it doesn\'t realize it.
There ar twenty five youngsters within the room, generally there\'ll be a minimum of 2 youngsters of constant birthday
lots of individuals can suppose this can be terribly rare with the birthday, very rare. however in truth, over twenty five folks during a variety of categories, there\'s a birthday constant chance of 2 or additional to over 0.5.
In any variety of teams up to twenty five folks. The presence of regarding three hundred attainable mixtures, which implies there\'s an excellent probability to own 2 birthdays on constant day.
there\'s over one universe
the globe isn\'t the sole one universe, however the universe includes a variety of 1 billion. this can be most thought cosmologists agree this read. within the past ten years, cosmologists have essentially reached a agreement that the universe we tend to board the universe could also be only 1 of the various, additionally to billions of alternative universes.
the sole conflict on this theory is whether or not there\'ll be the amount of the universe, moreover as people who exist within the universe is all constant laws of physics.
There ar over four dimensions
several physicists believe that the existence of our universe over four dimensions (the dimension is time), alternative dimensions too little, thus we will not be determined, or that one in every of our multidimensional area is found on the \"film\" floating In another higher dimensional world.
nobody is aware of what\'s the Computer
academic of engineering WHO ar skeptical regarding this issue: Abacus regarded computer? timepiece it?
nobody will extremely answer clearly, however it had been counseled to be distinguished: the pc cannot answer this question, it\'s this: The program can stop it?
Humans will answer this question, however the pc doesn\'t work, unless it initial stopped running program and so verify the solution.
Universe should never exist
An American physicist believes that the universe we live in should not be there, the universe would not be born from a big bang.
This physicists said he has yet to recover from the shock.
His calculations show that once stars die, it\'ll not cause the collapse of the method and also the formation of a singular purpose, and within the border region shaped round the event of any substance cannot escape - even as we tend to typically suppose.
On the contrary, owing to the massive quantity of radiation to require away the standard, the star can ne\'er be able to have an outsized enough mass to eventually collapse to create a part. This results in the question: initial explosion lit the fuse is currently thought-about from the offset cannot be established. If physicists calculations ar correct, then maybe a part doesn\'t exist, physicists can most likely have to be compelled to rethink the birth of the speculation of the universe.

NASA using older technology has become almost a tradition
Among our traditional thinking, always spacecraft are equipped with a variety of sophisticated techniques. But in fact, Orion NASA launched last week no less than a smart phone in your pocket much.
According to reports, for stability, performance, Orion internal computer is very limited. NASA is considering the creation of a more able to cope with the complex space environment - including the ultra-high G-forces and radiation - instead of using those new, untested technology. According to one engineer said, Orion is equipped with a single-core IBM PowerPC 750FX processor, you know this, but 12 years ago the product. By today's standards, it is definitely the ghost.
"What we want is stability and durability, rather than speed." An engineer at NASA explained. Another engineer is added to replace the new system is too expensive.
NASA using older technology has become almost a tradition, but it is actually a prudent choice. Orion is responsible for avionics deputy manager Matt Lemke said, the old processor among the more affordable space radiation. Newer processors risk of failure, and this is disastrous for the space mission it.
But Lemke also mentioned, Orion also use a lot of new technologies, such as for critical data transmission time-triggered Ethernet (Time-Triggered Ethernet).

If the earth is flat, people come to the edge will not fall?
For a long period of time, humans have thought that the earth is a big plane, although it will be understood ridiculous. So the question is: learn digging ...... if the earth is flat, people come to the edge will fall go? Scientists Answer: No, because you'll never get.
Foreign one called "flat earth" egg pain research organizations launched an investigation into this issue, the conclusion might subvert our previous idea: the more people who go to the edge, the more laid back, just like as in climbing. In the end, you will get on the ground because of physical exhaustion.
Why is this so? Because the more you go to the edge, being from the planet (and perhaps should be called the site a) the greater the gravitational center until you fall backwards because withstand far. All in all, you're not going away.
Ever since, scientists have regarded the hearts of many people for many years to answer questions, this is the most interesting place. So, next time do not know what other brain-hole can be filled?
