With the continuous development of network and information technology, the traditional financial accounting cannot meet the requirements of the development of the Internet era of big data. Management accounting will be financial management activities in theory and practice combination, more targeted and more widely and more practice, the enterprise must attention to this change, in order to meet the needs of the development of the enterprise business and bring more development space for the enterprise.展开更多

The PBL teaching mode adopted in this paper belongs to a new teaching method, which mainly depends on rich network and information resources, and takes students as the center to further strengthen the construction of knowledge, so as to ensure that students can master the ability of autonomous learning, so as to more deeply understand and understand knowledge. In order to further reflect the role of PBL model in Higher Vocational English teaching, this paper further analyzes the application of PBL model in Higher Vocational English Teaching under the background of big data. The specific contents are as follows.展开更多

According to the Hypothesis of primary particles, they exist in their basic, dynamic state, in their own flat spacetime, moving mutually at speeds much higher than the speed of light in a vacuum. Hence, a certain probability of a collision among these hypothetical particles exists, during which one of them would be abruptly decelerated to a speed greater than the border speed in our Universe, <i>c</i>, by a speed quantum, <i>ε<sub>u</sub></i>. As shown in this Hypothesis, such deceleration would increase the energy and the momentum of this particle immensely, so that in a very short period of time, they could tunnel into our Universe through the Big Bang, creating our total energy as well as our spacetime. With this theoretical consideration, we determined the power released during the Big Bang itself, the time period during which it took place, and its radius: <i>P<sub>B</sub></i>≈1.63×10<sup>183</sup>W, <i>t<sub>B</sub></i>≈9.51×10<sup>-114</sup>s and <i>r<sub>B</sub></i>≈2.85×10<sup>-105</sup>m. Evidently, this approach allowed us to theoretically push the boundaries for the description of this singularity to values lesser than the Planck time and the Planck length. We expect that the results for the initial singularity itself will allow a more detailed study of the Big Bang.展开更多

We consider General Relativity, the first Friedmann equation and the Friedmann-Lema?tre- Robertson-Walker (FLRW) metric for a Comoving Observer. It is shown explicitly that the Horizon and Flatness Problems are solved, taking away an important argument for the need of Cosmic Inflation. A decrease of 2.1 cm/s per year of the present-day speed of light is predicted. This is consistent with the observed acceleration of the expansion of the Universe, as determined from high-redshift supernova data. The calculation does not use any quantum processes, and no adjustable parameters or fine tuning are introduced. It is argued that more precise laboratory measurements of the present-day speed of light (and its evolution) should be carried out. Also it is argued that the combination of the FLRW metric and Einstein’s field equations of General Relativity is inconsistent, because the FLRW metric implies a variable speed of light, and Einstein’s field equations use a constant speed of light. If we accept standard Big Bang theory (and thus the combination of General Relativity and the FLRW metric), a variable speed of light must be allowed in the Friedmann equation, and therefore also, more generally, in Einstein’s field equations of General Relativity. The explicit form of this time dependence will then be determined by the specific problem.展开更多

The derived formula dispels the Olbers paradox, confirming that the CMBR originates from the superposition of light radiated by stars in the whole universe, not the relic of the Big Bang. The dark-night sky and CMBR are all caused by Hubble redshift—the physical mechanism is the quantum redshift of the photon rather than cosmic expansion. So this theory supports the infinite and steady cosmology.展开更多
