    I finished my A levels 2 days ago, I'd like to thank you for all the lectures and the help throughout, I was in the Edexcel board but this benefited me greatly. I loved the jokes that were made in every video and the explanations and analogies were always simple and understandable, thank you so much for everything.♥️

    "Do the disbelievers not realize that the heavens and earth were ˹once˺ one mass then We split them apart? And We created from water every living thing. Will they not then believe?"
    "And We have placed firm mountains upon the earth so it does not shake with them, and made in it broad pathways so they may find their way."
    "And We have made the sky a well-protected canopy, still they turn away from its signs."
    "And He is the One Who created the day and the night, the sun and the moon-each travelling in an orbit."
    [Reference Quran: Surah 21, Verse 30, 31, 32, 33 (21:30-33) ]

    Sorry for ranting here but existensialism hit hard for me from thinking about the universe, it's heat death, our own mortality, and how we'll never be able to experience life again. I feel like I'm sliding down with nothing to hold on to and there's nothing I can do. SO SCARYYY

    • @KhalidibnAhmed

      islam is the answer.
      the reason we exist is to worship the one god so we obey him. we also get our morality from the holy quran {The words of god}
      there is a life after death, where the believers who do good will be rewarded in Paradise and the disbelievers and the oppressors will be punished in hell and it willl be eternal

    Miss, in this playlist you did not discuss the 25.2 Stellar Radii objectives from the topic.
    Also, in 25.3 from the 2022 Syllabus, you did not explain (3) why redshift leads to the idea that the Universe is expanding and (2) using ∆λ / λ . ∆f/f . v / c. So will that be covered in a future video? And, the sources of error are not specifically mentioned in our syllabus, so should we learn them?

    Hello , your videos r really easy to understand and simple. But I am unable to recall all this during the exams due to the lecture notes not being available. Will it be possible to tell where the lecture notes are , it would be really appreciated.

    this theory wanna state that earth is centre of universe??

    • @ETphysics
      @ETphysics  10 หลายเดือนก่อน

      No, although we observe everything moving away from us, actually everything is expanding away from everything and we haven't been able to pinpoint a "centre of universe" (in our three dimensions, at least).
      Hmm i guess the image used is slightly misleading 🤔
