(a)तेजोमेघ परिकल्पना / Nebular Hypothesis

(b)उल्का-उत्पत्ती परिकल्पना / Meteorite Hypothesis

(c)ग्रहकण परिकल्पना / Planetesimal Hypothesis

(d)भरती परिकल्पना / Tidal Hypothesis

(I)जेम्स जीन्स / James Jeans

(II)मुल्टन / Moulton

(III)लॉकीयर / Lockyer

(IV)लाप्लास / Laplace

1)II I III IV
2)III II IV I
3)IV III II I✓ Correct
4)I II IV III

Nebular Hypothesis was proposed by Laplace, Meteorite Hypothesis by Lockyer, Planetesimal Hypothesis by Chamberlin and Moulton, and Tidal Hypothesis by Jeans and Jeffreys, corresponding to sequence IV III II I.

खालीलपैकी कोणत्या निरीक्षणामध्ये विश्व स्थिर नसून ते विस्तारीत आहे याबद्दल पुष्टी मिळते ? Which of the following confirms that the universe is not static but expanding ?

1)(1) दूरवरच्या आकाशगंगेमधून येणाऱ्या प्रकाशात आढळणारे लाल रंगाकडील विस्थापन / Red shift in the light coming from distant galaxies✓ Correct
2)(2) दूरवरच्या आकाशगंगेमधून येणाऱ्या प्रकाशात आढळणारे निळ्या रंगाकडील विस्थापन / Blue shift in the light coming from distant galaxies
3)(3) कृष्ण विवाराच्या जवळून जाताना होणारे प्रकाशाचे वकीभवन / Bending of light while passing near to the Black hole
4)(4) प्रकाशाच्या वेगाची स्थिरता / Constancy of velocity of light

The red shift in the light coming from distant galaxies indicates that galaxies are moving away from us, which confirms that the universe is expanding (Hubble's Law).

(c)चेंबर्लिन

(d)जेम्स जीन्स

1)I II III IV
2)III I IV II
3)IV I III II
4)II III IV I✓ Correct
