The World’s biggest airplane that was designed for use space searchs,flied firstly.Chord is 117 m.Gigantic airplane will produce satellite move to orbit.
Designed by American Space Company Stratolaunch Systems.It has 6 Boeing 747 engines.Reaches to 304 km speed.
One of Nasa Managements Thomas Zurbuchen said:”We can send airplane send to side of space.”
“All of you have been very patient and very tolerant over the years waiting for us to get this big bird off the ground, and we finally did it,” Stratolaunch CEO Jean Floyd told reporters on a press call.
“The systems on the airplane ran like a watch,” test pilot Evan Thomas told reporters.
One day soon, Stratolaunch hopes to carry 250-ton rocket ships loaded with satellites to a height of 35,000 feet—into the stratosphere. Once at cruising altitude, a rocket’s engines would ignite, carrying it and its satellite cargo the rest of the way into space.
Barclays warns of ‘likely’ second-half slowdown for Sage
The analysts have noted that the comparatives get more difficult as the year progresses, and that any slowdown could disappoint the market
Investigators at Barclays have cautioned that a second half lull for Sage Group PLC (LON:SGE) “appears to be likely”.
Sage, which makes bookkeeping programming for organizations, has seen its offer value move by just about a fifth this year in the wake of garnish desires with its first-quarter development.
But Barclays’ number crunchers have warned that the first half benefits from easier comparatives, while things get a little tougher in the second half of the year.
“We think Q1 should not be viewed as an especially material data point in assessing the growth rate of the business over the coming couple of years,” read a note to clients.
“It is likely that the [cloud] transition will gather speed over the course of the year – a good thing – but that this will result in revenue growth moderating. This could be further exacerbated by tougher comps in the second half of the year.”
The analysts added: “We think an H2 slowdown is likely and that this could disappoint the market.
“We therefore remain ‘underweight’, albeit on an increased price target of 550p (from 495p), now based on 17x CY20E EPS (from 15x) to reflect increased market multiples.”
Sage shares were 0.1% higher at 702.8p on Friday morning – comfortably ahead of Barclays’ target.
The first scientific photograph of black hole,the most mysterious point of universe,was taken by 200 scientists.
Scientists working on the Event Horizon Telescope Project have produced an image of the unseeable,capturing the world’s first photograph of black hole.
It took nearly two years for 200 scientists and a network of eight radio telescopes spanning the globe to make the breakthrough,which was previously thought impossible.
The first photograph of ”Monster”named black hole,changed science history.It’s became proof of Einsetin’s theory of relativity..
Monster is distant 53million light years from the World.It’s in M87 Galaxy.
Intelligent physicist Albert Einstein,had claimed that there’re black holes in the universe in his theory of relativty.Unseenable black holes are the most mysterious and the wildest areas in the universe.
Black holes swallow stars,planets,gases,dusts and electromagnetic radiation.
Monster is greater 3million times than the World.
THEORY OF RELATIVITY
The Theory of Relativity, proposed by the Jewish physicist Albert Einstein (1879-1955) in the early part of the 20th century, is one of the most significant scientific advances of our time. Although the concept of relativity was not introduced by Einstein, his major contribution was the recognition that the speed of light in a vacuum is constant and an absolute physical boundary for motion. This does not have a major impact on a person’s day-to-day life since we travel at speeds much slower than light speed. For objects travelling near light speed, however, the theory of relativity states that objects will move slower and shorten in length from the point of view of an observer on Earth. Einstein also derived the famous equation, E = mc2, which reveals the equivalence of mass and energy.
When Einstein applied his theory to gravitational fields, he derived the “curved space-time continuum” which depicts the dimensions of space and time as a two-dimensional surface where massive objects create valleys and dips in the surface. This aspect of relativity explained the phenomena of light bending around the sun, predicted black holes as well as the Cosmic Microwave Background Radiation (CMB) — a discovery rendering fundamental anomalies in the classic Steady-State hypothesis. For his work on relativity, the photoelectric effect and blackbody radiation, Einstein received the Nobel Prize in 1921.
Theory of Relativity – The Basics
Physicists usually dichotomize the Theory of Relativity into two parts.
The first is the Special Theory of Relativity, which essentially deals with the question of whether rest and motion are relative or absolute, and with the consequences of Einstein’s conjecture that they are relative.
- The second is the General Theory of Relativity, which primarily applies to particles as they accelerate, particularly due to gravitation, and acts as a radical revision of Newton’s theory, predicting important new results for fast-moving and/or very massive bodies. The General Theory of Relativity correctly reproduces all validated predictions of Newton’s theory, but expands on our understanding of some of the key principles. Newtonian physics had previously hypothesised that gravity operated through empty space, but the theory lacked explanatory power as far as how the distance and mass of a given object could be transmitted through space. General relativity irons out this paradox, for it shows that objects continue to move in a straight line in space-time, but we observe the motion as acceleration because of the curved nature of space-time.
Einstein’s theories of both special and general relativity have been confirmed to be accurate to a very high degree over recent years, and the data has been shown to corroborate many key predictions; the most famous being the solar eclipse of 1919 bearing testimony that the light of stars is indeed deflected by the sun as the light passes near the sun on its way to earth. The total solar eclipse allowed astronomers to — for the first time — analyse starlight near the edge of the sun, which had been previously inaccessible to observers due to the intense brightness of the sun. It also predicted the rate at which two neutron stars orbiting one another will move toward each other. When this phenomenon was first documented, general relativity proved itself accurate to better than a trillionth of a percent precision, thus making it one of the best confirmed principles in all of physics.
Applying the principle of general relativity to our cosmos reveals that it is not static. Edwin Hubble (1889-1953) demonstrated in 1928 that the Universe is expanding, showing beyond reasonable doubt that the Universe sprang into being a finite time ago. The most common contemporary interpretation of this expansion is that this began to exist from the moment of the Big Bang some 13.7 billion years ago. However this is not the only plausible cosmological model which exists in academia, and many creation physicists such as Russell Humphreys and John Hartnett have devised models operating with a biblical framework, which — to date — have withstood the test of criticism from the most vehement of opponents.
Theory of Relativity – A Testament to Creation
Using the observed cosmic expansion conjunctively with the general theory of relativity, we can infer from the data that the further back into time one looks, the universe ought to diminish in size accordingly. However, this cannot be extrapolated indefinitely. The universe’s expansion helps us to appreciate the direction in which time flows. This is referred to as the Cosmological arrow of time, and implies that the future is — by definition — the direction towards which the universe increases in size. The expansion of the universe also gives rise to the second law of thermodynamics, which states that the overall entropy (or disorder) in the Universe can only increase with time because the amount of energy available for work deteriorates with time. If the universe was eternal, therefore, the amount of usable energy available for work would have already been exhausted. Hence it follows that at one point the entropy value was at absolute 0 (most ordered state at the moment of creation) and the entropy has been increasing ever since — that is, the universe at one point was fully “wound up” and has been winding down ever since. This has profound theological implications, for it shows that time itself is necessarily finite. If the universe were eternal, the thermal energy in the universe would have been evenly distributed throughout the cosmos, leaving each region of the cosmos at uniform temperature (at very close to absolute 0), rendering no further work possible.
The General Theory of Relativity demonstrates that time is linked, or related, to matter and space, and thus the dimensions of time, space, and matter constitute what we would call a continuum. They must come into being at precisely the same instant. Time itself cannot exist in the absence of matter and space. From this, we can infer that the uncaused first cause must exist outside of the four dimensions of space and time, and possess eternal, personal, and intelligent qualities in order to possess the capabilities of intentionally space, matter — and indeed even time itself — into being.
Moreover, the very physical nature of time and space also suggest a Creator, for infinity and eternity must necessarily exist from a logical perspective. The existence of time implies eternity (as time has a beginning and an end), and the existence of space implies infinity. The very concepts of infinity and eternity infer a Creator because they find their very state of being in God, who transcends both and simply is.
PewDiePie incidentally ousted as most well known YouTuber
Swedish gamer and vlogger PewDiePie has lost his crown as the YouTube star with the most endorsers.
Indian channel T-Series, which share Bollywood film trailers and music recordings, a week ago beat the star with thousands a greater number of supporters than PewDiePie’s.
PewDiePie, real name Felix Kjellberg, posted a video yesterday (March 31) congratulating his rival – and chucked in some shade for good measure.
“All it took was a massive corporate entity with every song in Bollywood,” he sings in the video.
But it appears that PewDiePiew has now bounced back to the top spot. At the time of writing he has 92,190,716 subscribers to T-Series’ 92,168,949. That leaves a margin of 21, 767 subscribers between them.
Bhushan Kumar, who owns T Series, recently told BBC News that he was “not bothered” about winning the race. “I don’t even know why PewDiePie is taking this so seriously,” he said.
“I have not told my artists to put up supportive messages to boost our followers on our channel. We are not in that game.”
Somewhere else, a month ago PewDiePie said he was “completely sickened” after he was named by the shooter who live-spilled the ruthless shooting at a mosque in Christchurch, New Zealand.
The shooter referenced the YouTube star as he started a Facebook stream of the shooting.
PewDiePie later composed on Twitter: “Simply heard updates on the overwhelming reports from New Zealand Christchurch. I feel totally sickened having my name expressed by this individual. My heart and considerations go out to the people in question, families and everybody influenced by this disaster.”
