    समय (Samay) क्या हैं || What is Time? (व्हाट इस टाइम) || क्या समय यात्रा संभव है? || Kya Samay Yatra (समय यात्रा) possible hai? (Just in 7 Minutes) || Hindi ||
    In this video we will learn what exactly is time (समय क्या हैं) and what are its properties. Does it move at a same speed for all? Is time an illusion? Watch this video to get a good idea about the concept of time!

    क्या समय ek hi speed se chalta hai sabke liye?
    Iske liye hume Theory of Relativity aur Light ke speed pe thoda research karna hoga. Time does not move at a same speed for all but is relative to the speed at which an object is travelling.

    सापेक्षता के सिधांत (relativity)
    Hume Samay ko samajhne ke liye Einstein ka सापेक्षता के सिधांत (relativity) theory study ke bare mai jaanana hoga. We have discussed that in this video!

    अंतरिक्ष और समय kaise milke ban gaye अंतरिक्ष समय. Ye bhi iss video mai discuss kiya hai.

    समय यात्रा - समय यात्रा क्या है? क्या समय यात्रा संभव है? (Is time travel possible?) can we travel backwards in time?

    समय यात्रा sambhav nahi hai kyuki big bang ke baad time ko aisi hi property mili jisse woh aage hi badhega. Aur 2nd law of thermodynamics bhi iske base pe bana hai jo ki ek universal law hai.

    समय क्या है what is time samay [ HINDI ]

    TIme (समय) hum sabke zinbdagi ka ek bahot important hissa hai. Hum sab ye jaante hai ki time kabhi kisi ke liye rukta nahi hai aur hamesha aage hi badhta hai. Time(समय) ka arrow jo hai who hamesha present se future ke taraf hi badhta hai aur na ki present se past. Lekin ye toh time ka ek bahot basic understanding hai . App ye toh jaante rahoge ki ki clocks aur watches ke invention se pehle bhi time exist karta tha aur ye clocks sirf ek measuring device hai of time. Toh Time (समय) exactly hai kya aur ye itna important kyu hai. Physics hi aisa subjects hai jisme hum iske detailed study kar sakte hai.. Toh aaiye time ke bare mai jaante hai..
    Toh time (समय) ki history bahot lambi hai.. Time aur iske actual properties hum jaanne lage after studying the fastest thing in the universe, light.
    Well iss theory mai Einstein ne bataya ki in order for the speed of light to be constant at 186,000 miles per second, ek element ka slow down ho jana zaroori hai. Aur ye element hai Time.
    Toh iska ek bahot simple meaning tha matlab agar ek object motion mai hai aur woh around light speed travel kar raha hai like 90 percent of the light speed, toh uske liye time slow down ho jayega to maintain the constant and consistent speed of light. Time ke slow down ho jaane ke vajah se who object ke liye light ki speed uske speed ke comparison constant hi rahegi jo hai 186000 kms per hour. Ye sunne mai thoda awkward zaroor lagega kyuki hum isse day to day life mai experience nahi karte but ye ek reality hai aur ye bahot tests pass kar chukka hai.
    Iss pheneomenon ko Einstein ne kaha Time Dilation. Einstein space aur time ko ek hi element maante the. Unke hisaab se space aur time alag nahi but jude huye hai apas mai. Aap jitney speed se space space dimensions mai aage badoge aap utna hi slow time dimension mai aage badhoge. Aur agar ye aap light ke speed ko reach kar diye toh time aapke liye ruk jayega aur aap time dimension bilkul bhi aage nahi badhoge. But kyuki light massless particles hai humne jaana tha pehle toh light ke speed ko hum kabhi nahi reach kar sakte. It is impossible as mass ke hote huye utne speed mai acceleration aur mass attract karega aur as a result mass aur increase hota rahega acceleration ko slow karte huye.

    Aur theory ke hisaab se agar hum light ke speed ko bhi exceed kar sake toh time (समय) mai backward jaana possible ho sakta hai. However ye sirf theory hai aur maybe possible nahi bhi ho sakta hai kyuki ho sakta hai ki bing bang ke baad jab time create hua toh uska nature hi aisa raha ki who hamesha aage hi badhega. Jise hum second law of thermodynamics mai bhi dekh sakte hai jo kehta hai entropy always increases with time. Jiska matlab hai koi bhi cheez hamesha ek orderly state of existence se disordered state of existence mai transform hoti hai with time. Jo ye batane mai help karta hai ki big bang se pehle entropy sabse kam raha hoga aur jaise time aage badh raha hai who increase ho raha hai aur poora universe zyada disordered state mai slowly transform ho raha hai with time. Toh guys iss video ke liye bas itna hi. Humne ye jaana ki time element actually mai kya hota hai.Humne ye jaana ki time har kisi ke liye relative hota hai depending upon their speed.
