2.735 K to degrees Celsius is the average temperature of the universe. But, how can we measure it ? & How scientists measured it ?

আপনি কোনটা জানতে চাচ্ছেন? Practically না Theoretically?Practically মাপা হয়েছিল রেডিও টেলিস্কোপ দিয়ে।তবে Theoretically কীভাবে করা যায় সেটা বলতে পারব না। তবে যাই হোক খুব সোজা কিছু নিশ্চয়ই হবে না। আমি একটা উপদেশ দিতে পারি; Google-এ সার্চ দিতে পারেন। :)

Link or source?I knew a group of scientists measured it theoretically.(Source:একটুখানি বিজ্ঞান)
BTW, either write in english or in bengali.Don't write in this way.It's not so cool.

তাপ মূলত তড়িৎচুম্বকীয় তরঙ্গ। সুতরাং তাপ থাকরে তরঙ্গ বিকিরণ হয়। তরঙ্গের দৈর্ঘ্য নির্ভর করে কত তাপ আছে তার উপর। সুতরাং পৃথিবীর চারদিক থাইকা যেই বিকিরণ আসতেছে সেইটার তরঙ্গদৈর্ঘ্য পরিমাপ করলেই তাপমাত্রা পাওয়া যাবে।

আর তাত্ত্বিকভাবে জেনারেল রিলেটিভিটির মাধ্যমে মহাবিশ্বের তাপমাত্রা কোন সময় কত ছিল তা বাইর করা যায়। এইটা কসমোলোজিস্টদের কাজ।

আমার ধারণা, মোট তাপশক্তি আর মোট ভোর জানলেই তো হয় । নাকি ?
