Feynman: When we were talking about the atoms, one of the troubles that people have with the atoms is that they're so tiny, and it's so hard to imagine the scale.

The size of the atoms are in size - compared to an apple, it's the same scale as an apple is to the size of the Earth. And that's a kind of a hard thing to take, and you have to go through all these things all the time, and people find these numbers inconceivable. And I do too.

The only thing you do is you just change your scale. I mean, you're just thinking of small balls, but you don't try to think of exactly how small they are too often! Or you'd get kind of a bit nutty, alright?

But in astronomy, you have the same thing in reverse because the distances to these stars is so enormous, you see. You know that light goes so fast that it only takes a few seconds to go to the moon and back, or it goes around the Earth seven-and-a-half times in a second. And goes for a year, two years, three years before it gets to the nearest other star that there is to us.

But all of our stars are... the stars that are nearby in a great galaxy, a big mass of stars, which is called a galaxy, a group, well this, our galaxy is... what is it? Something like a hundred thousand light years, a hundred thousand years.

And then there's another patch of stars. It takes a million years for the light to get here, going at this enormous rate.

And you just go crazy trying to make too "real" that distance, you have to do everything in proportion. It's easy - you say the galaxies are little patches of stars and they're ten times as far apart as they are big.

So that's an easy picture, you know - he gets it. But you just go to a different scale, that's easier. You know, once in a while you try to come back to... Earth scale to discuss the galaxies but it's kind of hard.

The number of stars that we see at night is about - only about 5,000. But the number of stars in our galaxy, the telescopes have shown when you improve the instrument... Oh! We look at a galaxy. We look at the stars. All the light that we see, the little tiny and influent spreads from the star over this enormous distance of what? Three light years, for the nearest star. On, on, on! This light from the stars spreading, the wavefronts are getting wider and wider, weaker and weaker, weaker and weaker out into all of space, and finally the tiny fraction of it comes in one square, eighth of an inch, tiny little black hole and does something to me, so I know it's there.

Well, to know a little bit more about it, I'd rather gather a little more of this little, this tiny fraction of this front of light, and so I make a big telescope, which is a kind of funnel that the light that comes over this big area - 200 inches across - is very carefully organised, so it's all concentrated back so it can go through a... pupil. Actually, it's better to photograph it, or nowadays they use photo cells, they're a better instrument.

But anyway, the idea of the telescope is to focus the light from a bigger area into a smaller area so that we can see things that are weaker, less light, and in that way we find there's a very large number of stars in the galaxy.

There's so many that if you tried to name them, one a second, naming all the stars in our galaxy, I don't mean all the stars in the universe, just this galaxy here, it takes 3,000 years.

And yet, that's not a very big number. Because if those stars were to drop one dollar bill on the Earth during a year, each star dropping one dollar bill, they might take care of the deficit which is suggested for the budget of the United States.

So you see what kind of numbers we have to deal with!

Haha don’t mind me I’m just thinking about-

The speed of light is 299,792,458 meters per second so we are technically seeing everything how it was in the past but because of how fast light travels it’s practically unnoticeable but it’s slower the further you look into space with a telescope, we see the moon how it was 1.3 seconds ago, the sun as it was 8.3 minutes ago and the closest star how it was 4 years ago. The closest galaxy is 2.5 million years ago and we can look so far that we can see the universe as it was forming 4 billion years after it began to technically humans CAN time travel, in this essay I will-

#yeah so anyways #if you are reading this with the mental image that this gets progressively more unhinged you are reading it correctly #my unhinged rants #science is cool #science #space #unintelligible goblin noises #time travel #speed of light #physics

7 Heavens and 7 Earth ? Yes it is but we cant move

Quran is very clear that Allah created 7 heavens and 7 earth in 6th CE which science has also approved in the name of parallel universe and mirror image of our universe etc.

“It is Allah Who has created seven heavens and of the earth the like thereof (i.e. seven). His Command descends between them (heavens and earth), that you may know that Allah has power over all things, and that Allah surrounds (comprehends) all things in (His) Knowledge.” [65:12]

But it is Allah alone who grants approval to discover the secrets of His creation only that much what He desires for humans and Jinns.

“O company of jinn and human, if ye have power to penetrate all the regions of the heavens and the earth, then penetrate them! You will never penetrate them save with Our approval [55:33]

This is very powerful verse in the Quran and a direct challenge to the human-beings and the whole world of Science that they cannot discover the mystery of the Allah’s creation, except ONLY what Allah will desire.

Dr. Derek P. Blake (Aerospace Engineer) so honestly said, “Essentially, we have explored 0% of the universe, and it will probably stay that way for as long as humans live. The universe is that big. I don't think we could ever get nearer to even 0.00001 percent”.

Only our Prophet was allowed to travel and see every creation of Allah, past and future through all these seven heavens and earth and their inhabitants also. He also saw the inhabitants of hell and heaven (the future) and all the prophets and messengers (past) and much more...

Is time travel possible, Albert Einstein said YES, just move faster than light, time will stop. EXCATLY, this happened when prophet returned back after his night ascension his bed was as warm as he just left it. [I personally believe, according to Quran verse 17:1, that it was a physical ascension and not at a dream or something spiritual] Buraq was a time travel machine in terms of speed as revealed by Prophet, so the Miraj or Night Ascension is as true as the sun and moon, scientifically because time stopped that night for Prophet.
