Did Buddha told anything about if we can travel to the end of the cosmos?
Did the Buddha tell us anything about reaching the end of the cosmos or time-travel through the means of experiencing all the Jhanas in meditation?

He wields manifold supranormal powers. Having been one he becomes many; having been many he becomes one. He appears. He vanishes. He goes unimpeded through walls, ramparts, & mountains as if through space. He dives in & out of the earth as if it were water. He walks on water without sinking as if it were dry land. Sitting crosslegged he flies through the air like a winged bird. With his hand he touches & strokes even the sun & moon, so mighty & powerful. He exercises influence with his body even as far as the Brahma worlds.

"Now, brahman, of these three miracles, which one appeals to you as the highest & most sublime?"
"Master Gotama, of these three miracles, the miracle of psychic power where a certain person wields manifold psychic powers... (and) exercises influence with his body even as far as the Brahma worlds: that is a miracle experienced only by him who does it; it belongs only to him who does it. It seems to me to be of the nature of an illusion.
"As for the miracle where a certain person gives instruction in this way: 'Direct your thought in this way, don't direct it in that. Attend to things in this way, don't attend to them in that. Let go of this, enter and remain in that': this is the miracle that, of the three, appeals to me as the highest & most sublime.

As he was standing there he said to the Blessed One: "Is it possible, lord, by traveling, to know or see or reach a far end of the cosmos where one does not take birth, age, die, pass away or reappear?"
"I tell you, friend, that it is not possible by traveling to know or see or reach a far end of the cosmos where one does not take birth, age, die, pass away, or reappear."

"I tell you, friend, that it is not possible by traveling to know or see or reach a far end of the cosmos where one does not take birth, age, die, pass away, or reappear. But at the same time, I tell you that there is no making an end of suffering & stress without reaching the end of the cosmos. Yet it is just within this fathom-long body, with its perception & intellect, that I declare that there is the cosmos, the origination of the cosmos, the cessation of the cosmos, and the path of practice leading to the cessation of the cosmos."

I tell you, it isn't through that sort of traveling that the end of the cosmos is known, seen, or reached. But at the same time, I tell you that there is no making an end of suffering & stress without reaching the end of the cosmos.
"These five strings of sensuality are, in the discipline of the noble ones, called the cosmos. Which five? Forms cognizable via the eye — agreeable, pleasing, charming, endearing, fostering desire, enticing; sounds cognizable via the ear... aromas cognizable via the nose... flavors cognizable via the tongue... tactile sensations cognizable via the body — agreeable, pleasing, charming, endearing, fostering desire, enticing. These are the five strings of sensuality that, in the discipline of the noble ones, are called the cosmos.

"There is the case where a monk — quite secluded from sensuality, secluded from unskillful qualities — enters & remains in the first jhāna: rapture & pleasure born of seclusion, accompanied by directed thought & evaluation. This is called a monk who, coming to the end of the cosmos, remains at the end of the cosmos. Others say of him, 'He is encompassed in the cosmos; he has not escaped from the cosmos.' And I too say of him, 'He is encompassed in the cosmos; he has not escaped from the cosmos.'

[Similarly with the second, third, & fourth jhānas, and with the attainment of the dimensions of the infinitude of space, the infinitude of consciousness, nothingness, and neither perception nor non-perception.]

"Furthermore, with the complete transcending of the dimension of neither perception nor non-perception, he enters & remains in the cessation of perception & feeling. [eg. nāma, mind] And, having seen [that] with discernment, his fermentations are completely ended. This is called a monk who, coming to the end of the cosmos, remains at the end of the cosmos, having crossed over attachment in the cosmos."

"Monks, I will teach you the All. Listen & pay close attention. I will speak."
"As you say, lord," the monks responded.
The Blessed One said, "What is the All? Simply the eye & forms, ear & sounds, nose & aromas, tongue & flavors, body & tactile sensations, intellect & ideas. This, monks, is called the All. [1] (http://zugangzureinsicht.org/html/tipitaka/sn/sn35/sn35.023.than_en.html#fn-1) Anyone who would say, 'Repudiating this All, I will describe another,' if questioned on what exactly might be the grounds for his statement, would be unable to explain, and furthermore, would be put to grief. Why? Because it lies beyond range."
