Dark Energy

This thesis is dedicated to every person who feels locked within the soundproof world of illness; feeling as though they are alone and forgotten. In particular to the many thousands of young women who are right now doing whatever they can to put their limited energy to good use: your dreams are still there in the stars, you just need a different way to reach them. If Marcel Proust is any example to live by, some of the most world-changing art can be made from within the confines of a dark, quiet bedroom sprawled with paper and ink.

Despite the prediction of the Higgs boson at Large Hadron Collider (LHC) in the CERN in 2012 after it has been theorized for over 50 years, however, the Standard model (SM) still can not explain the mass of neutrinos; the hierarchy problem; the contribution of dark energy, dark matter and CP violation in cosmology.

We find that this model can only fit the observational constraints if there is a cosmological constant and the presence of non-decaying cold dark matter in addition to decaying cold dark matter. Thus, although this remains a viable model, it is only able to partially explain the observed cosmic acceleration.

Under high plant density, intensifying competition among individual plants led to overconsumption of energy and nutrients and resulted in an almost dark condition in the lower strata of the canopy, which suppressed the photosynthetic potential of the shaded leaves. Leaf removal could help to ameliorate this problem and increase crop yields.

Rất nhiều người chưa có nghiên cứu nhiều về vũ trụ học thường nhầm lẫn 2 khái niệm này, coi chúng là một. Thực chất vật chất tối (dark matter) và năng lượng tối (dark energy) là 2 khái niệm hoàn toàn độc lập từ lịch sử đên bản chất. Chúng ta sẽ nói trước tiên về vật chất tối (dark matter) Năm 1933, Fritz Zwicky phát hiện ra sự xuất hiện của loại vật chất này khi đo vận tốc của các thiên hà trong quần thiên hà Coma. Người ta thường đo khối lượng của một thiên hà...

1) Begin class in the dark today. If possible, close blinds and turn off lights. Ask students if they know where their electricity comes from. Is it from a coal-fired power plant? Hydro-electric? Wind energy? Is the plant nearby? Have this discussion in the dark. 2) Turn on the lights and point out the ease with which the room was supplied electricity. Where does the power originate? Explain that students will investigate this today in class.
