Ki sa ki matyè nwa ak enèji nwa?

Oke matyè nwa ak enèji nwa se yon kesyon trè konfizyon sou tè a nan moman sa a ak depi nan kòmansman an. Se konsa, jodi a nou pral eseye konprann sou matyè nwa ak enèji.. Matyè nwa ak enèji nwa eksplike tou senpleman gen yon bagay ekstraòdinè ke nou te dekouvri sou linivè nou an. Matyè òdinè ak enèji ke nou fè eksperyans nan lavi chak jou fè mwens pase 5% nan sa ki deyò Matyè nwa fè moute sou 27% nan linivè a li te ye ak enèji nwa fè moute lòt la 68%. nou konnen trè ti kras sou matyè nwa ak enèji nwa pakonsekan mo dot yo te itilize pou dekri tou de.

Matyè nwa

1. Nature Dark matter is believed to be a kind of substance that neither emits nor reflects electromagnetic radiation, making it invisible and only detectable through its gravitational effects.
2. Effects The motion of visible matter (stars, galaxies, gas clouds) is influenced by dark matter due to their gravity. It is suspected to be responsible for the phenomena dubbed gravitational lensing where light from far away galaxies gets bent due to massive intervening bodies.
3. Distribution Dark matter is presumed to exist everywhere in the universe, forming halos around individual galaxies as well as clusters of galaxies.
4. Composition Although the exact composition remains unknown, dark matter might consist of non-baryonic particles such as WIMPs (Weakly Interacting Massive Particles) or axions i.e. other than protons and neutrons.

Dark Energy

1. Nature Dark energy is an enigmatic form of energy that fills all space and causes the expansion of the universe at an accelerating rate.
2. Effect Different from dark matter which attracts matter gravitationally, dark energy acts as a repulsive force and leads to an accelerated expansion of the universe over time. This acceleration counteracts the gravitational pull between galaxies and results in an overall expansion of the universe.
3. Distribution It appears that dark energy is evenly spaced throughout space and affects the large-scale structure of the cosmos.
4. Origin What exactly is dark energy and where does it come from are not yet known. One hypothesis is that this could be vacuum energy or a cosmological constant associated with empty space itself.

Ki sa ki matyè nwa ?

Mwen pral prezante yon ti detay sou sa nou konnen jiskaprezan matyè nwa. Matyè nwa se yon fòm matyè ki pa kominike avèk limyè e se konsa li se envizib pou nou paske kalkil yo te montre ke san li galaksi rale gravitasyonèl ak lòt gwo estrikti nan linivè a pa ta kapab fòme matyè nwa tou oblije eksplike mouvman galaksi yo.. Li eksplike poukisa zetwal ak nyaj gaz ki nan katye yon galaksi vire osi vit ke yo fè sa.

Einstein dekri yon kontinyèl espas-tan kòm twal la nan Cosmos espas-tan enkòpore twa yo
dimansyon espas monte ak desann,gòch ak dwa ak dèyè. Katriyèm dimansyon tan Einstein te panse de espas-tan kòm mas pèrmeabl ak enèji ka defòme espas-tan e sa bay fenomèn gravite.. Matyè nwa gen mas, kidonk li pwodui gravite. Kote ki gen gwo touf li matyè nwa defòme limyè ki soti nan galaksi dèyè li. Efè distorsion sa a rele lantiy gravitasyonèl. Nou te sou lachas pou matyè nwa pou dè dekad ak konsansis jeneral nan mitan kosmolojis.

Ki sa ki se enèji nwa ?

Li ka fèt ak yon patikil subatomik ekzotik ke nou poko detekte enèji nwa 1929 astwonòm Edwin Hubble te dekouvri linivè a ap grandi pi lwen yon objè a soti sou tè a, se pi wouj li parèt kòm longèdonn limyè li yo ap vin nan direksyon nou.. Li se lonje spectre elektwomayetik la se seri a tout antye de limyè ki egziste soti nan vag radyo a gama reyon limyè vizib se radyasyon elektwomayetik nan pòsyon nan spectre Electra ki ka wè pa je imen an.. Longèdonn ki pi long yo koresponn ak yon chanjman nan fen wouj nan spectre elektwomayetik la.

Hubble remake ke pli lwen yon galaksi te plis deplase wouj la, li te vin ak apre yon analiz detaye sou diferan chanjman wouj. Li te konkli ke galaksi yo t ap vole lwen youn ak lòt e linivè a t ap grandi nan gwosè jiska fen ane 90 yo.. Li te siyen panse li ke ekspansyon sa a nan linivè ta swa ralanti oswa menm kontra akòz efè gravite nan matyè.. Sepandan nan 1998 prèv obsèvasyon konfime ke ekspansyon linivè a te aktyèlman akselere, sa ki te lakòz akselerasyon sa a te ame enèji nwa ak li la tou pa gen anyen, se konnen sou enèji nwa sa a. Men, li ka konsidere kòm yon pwopriyete nan espas. Yon espas ap agrandi ak plis espas ap parèt pou ranpli espas siplemantè a.

La dark energy intrinsic to space is pushing galaxies further apart and that concludes my inquiry on dark matter and dark energy. Sa a se evidamman yon BECA trè wo nivo de tou de sijè ak atik sa a vle di yo dwe itilize kòm yon tranplen pou plis etid kòm toujou mwen espere ou te renmen atik sa a..

pair of identical but connected concepts in cosmology that are highly important for the shaping and dynamics of the universe. This is followed by a short explanation on what differentiates them.

In conclusion, though both provide insights into cosmic dynamics, there exist differences between dark matter and dark energy in terms of their properties, impacts and roles in cosmology. Gravitational effects from Dark Matter help keep galaxies together and induce motion while on the other hand matters about expansion through gravitational pull requires Dark Energy.
