Status Updates From The Universe in Your Hand: ...

For now, however, you'll have to accept that you just reached the end of the visible universe. It is a surface that has been detected, and mapped, with our telescopes. The surface of a wall that no light can cross. It has been called the surface of last scattering.

Andromeda, for one, may very well be teeming with life. It is the largest of all the galaxies that surround ours. And it is very close. On a galactic scale, that is. Not a human one. A call made right now from Earth to some place around one of its 1,000 billion stars would take about 2.5 million years to reach its destination. If we were to make contact, we'd better find an intelligent question to ask.

he had claimed that there were 'countless Suns and countless Earths all orbiting around their Suns'. He died in agony for believing so.

Even during some of the darkest years of humanity's chaotic past, some people heroically defied the religious authorities by asserting that, indeed, other worlds probably existed. The Italian Catholic monk Giordano Bruno, for one, got burnt alive in Rome in 1600, for having dared to speak such a heretical thought out loud:

Using such a telescope, they still cannot see an object, but they do see energetic bursts of light originating within the ring, from some tiny location there. What keeps S2 from shooting away not only isn't a star, it is also far from being as big as it should be. So much so, in fact, that scientists have only one explanation for what must be hiding there: a black hole. A supermassive one.

It's funny to think that Pluto, with its moon Charon, is so far away from the Sun, and has so much space to travel to complete a single revolution of it, that less than one of its own years has passed between the moment it was discovered and called a planet, and the moment it got stripped of that title, seventy-six Earth years later.

It is by estimating the amount of hydrogen left in our star's core that scientists can guess when this explosion will happen, and the result says that the Sun will blow up in about 5 billion years from now, on a Thursday, give or take three days.

A bit hammy so far with all the "you are flying through space, and you are thinking this and that," and "You see this light/planet/thing and want to take a close look, so you're flying through space towards it," stuff, but easily readable.

Today we humans could at least hope to detect a threatening asteroid early enough to try to deflect it. So we already have some powers they did not have. It might be unfair to say it, but with hindsight we might thus link the dinosaurs' extinction to their lack of awareness of theoretical physics.



LOL.

And then, once you've seen everything that is known, you will jump into the unknown and see what some of the brightest theoretical physicists of today are working on to explain the very strange realities we happen to be a part of. Parallel universes, multiverses and extra dimensions will enter the picture.

Travelling throughout our universe, you will discover what gravity is about and how atoms and particles interact with each other without ever touching each other. You will find out that our universe is mostly made up of mysteries and that these mysteries have led to the introduction of new types of matter and energy.
