Puṣṭa Kṛṣṇa: Another question is "How do the different seasons come about-winter, summer, spring?"
Prabhupāda: That is due to the movement of the sun.
Puṣṭa Kṛṣṇa: The...?
Prabhupāda: Movement of the sun.
Puṣṭa Kṛṣṇa: Movement of the sun.
Prabhupāda: But they say sun if fixed up.
Puṣṭa Kṛṣṇa: Yes, they say the earth is tilting back and forth like this.
Prabhupāda: That is always doing, but it takes little time. But the movement of the sun, uttara and dakṣiṇa, what is their explanation?
Puṣṭa Kṛṣṇa: They say that the earth is tilting like this. The sun is fixed. When the earth tilts like this in the northern hemisphere there is summer, and when it tilts like this, the southern hemisphere, there's summer. It's tilting back and forth as it revolves around the sun.
Prabhupāda: Tilting?
Puṣṭa Kṛṣṇa: Yes.
Prabhupāda: But they say it is...
Pañca-draviḍa: Well, they say the earth is on a tilted axis.
Trivikrama: Twenty-three degrees from the north pole.
Pañca-draviḍa: So, as it revolves around the sun...
Puṣṭa Kṛṣṇa: That's another theory too.
Prabhupāda: Eh?
Puṣṭa Kṛṣṇa: There's two different theories.
Haṁsadūta: It's simultaneously going around the sun, and also, in itself, it is turning. And then it's sometimes tilting on a particular axis. It's simultaneously moving around the so-called central sun...
Prabhupāda: But for six months that, it tilts?
Haṁsadūta: And then it also spins, the globe spins, and then it also...
Prabhupāda: Eh?
Haṁsadūta: It has different tilts. It takes different degrees.
Tamāla Kṛṣṇa: The tilt is always the same.
Haṁsadūta: And when the sun's rays hit the earth at a particular angle, it becomes cooler or hotter. This is their sum and substance.
Tamāla Kṛṣṇa: While it's spinning, it's not just spinning straight up and down. It's on an axis. So it's spinning like this, not like this. Like this.
Pañca-draviḍa: It's on an angle.
Haṁsadūta: Yeah. And then it is tilting.
Puṣṭa Kṛṣṇa: But how does that explain summer and winter?
Tamāla Kṛṣṇa: Because it's close to the sun in...
Pañca-draviḍa: Because it's close to the sun and.... No, it's not closer.
Puṣṭa Kṛṣṇa: It spins. Every twenty-four hours it's turning. Why should that matter?
Pañca-draviḍa: No, but the orbit around the sun is...
Puṣṭa Kṛṣṇa: Elliptical.
Pañca-draviḍa: Yes. Elliptical.
Haṁsadūta: Yeah, for instance, in Sweden, they have a certain part of the year when it is always dark. So they say this is because the earth's axis has shifted so that.... Yeah.
