can only travel to past in Same Universe by travel faster than lite.

past travel on alt universe is easier, but allows for no return to same universe as departed.

I heard that when you pass the event horizon of a black hole and fall into the singularity you rapidly approach the heat death of the universe in terms of how much time has passed.

Is that true?

Notice how the lensing is almost unobservable for light that passes past a few times the radius of the event horizon. When viewed from Earth, the bent light forms an extremely tiny point.

>not posting the gif that makes you think

Maybe more simply said, how does a black hole grow?

I like the use of the word singular but I don't believe you are using it in the context of monism or a cosmological singularity

Like this.
Note that the sky wouldn't be blue in the day, duh.

Gravity is real, yes.

Cogito ergo sum

It's the theory that the universe is the way it is right now simply because we can observe
it to determine that it is the way it is.
How about I observe, therefore the universe exists.
In other words, on this particular world, there are sentient beings that are called humans , now then, by discovering the laws of physics and constants, human beings can observe the fact that the universe actually
exists at all, and when that happens, the existence of the universe becomes apparent to whomever is observing it , therefore we can say that the human beings who observe the universe, if we had not actually evolved as far as they (we) did , then there wouldn't be any observations therefore the universe would cease to exist due to not having anyone capable of acknowledging it's existence in the first place, so it wouldn't really matter if the universe existed or not, the universe is, simply because human beings know it is, and know it exists. In other words, one of you in here, are literally creating the universe right now.

-- Now, this " theory " to some, seems logical, if not presumptuous in most aspects, especially concerning reality on a logical, if not infinitesimal scale, BUT, reality, and spacetime are not bound by the so called laws of rationality, and this becomes especially true for black holes.

The universe, said by some, believed by almost none, (worm hole balloon experiment) said to contain other universes like ours, which connect other universes to our own, does not account for cogito ergo sum, because where logic starts in the universe, it stops at a black hole.

So, if black holes are "warp holes" into other universes, and you somehow manage to create a craft capable of surviving the transition from our universe into the next (assuming there IS another universe upon exiting the end of the black hole), and then finding a black hole in the newly found universe, you go through that one, into a 2nd black hole, into a 2nd universe...(continued)

http://en.wikipedia.org/wiki/Gauss%27s_law may be helpful in conceptualising this if you're good at vector calculus. But yeah, I'm slightly confused by the question. "maximal gravity at a given point in space"... if it's at a point I'm guessing it'll be a thin cylinder behind the point...? Look at the equations you use there though, if you can get your head round them.

Gravity and time are just properties of space. Only space is real. Space is very material but we don't know enough to say what it's made of.

So today a relative died (old grandpa cousin). Family reunion above hundred people.
Meet a 3 cousin and he present me her cousins.
>Cousin I meet : she study liberal arts
>His brother: he is economist student
>A theoretical cousin: she is a lawyer student
>Her sister is a med student
>Another theoretical cousin: he study liberal arts
>I am ME student

Folks start talking about their degrees, I keep talking about maths and statistics with the economy guy. Else are talking about professors that give low grades. Suddenly the med girl start talking about them classes and funny experiences while everyone was disgusted I was cool.
>thank 4chan to make immune to gore images or stories
Then the English major says something about philosophy
>me: implying philosophy is similar to theology, I cant stand post greek lectures which are like fairytale stories.
>lawyer girl: yes philosophy seems to be a little illogical
AWKWARD SILENCE... realise that I was having odd attitude toward the art liberals dudes
>fuck you 4chan, I almost said >>>/lit/

This is a thread about string theory btw

ITS A TANGIBLE EVENT YOU STUPID.

GOOGLE HUBBLE DATA.

I just had an idea and I want discussion on it.

So, in order to enable quick space travel or WARP-esque technology, we need an energy source that pumps out more power than anything we can produce at this point, possibly in the range of some hundred or thousand nuclear bombs.

Now the problem is, how do we pack so much energy on a vessel? Could we create man-made black holes, "feed" them and use their energy as fuel? Could we directly use a black hole as propulsion by channeling and/or maybe reversing their force (from pull to push, channeled into one direction)? Could we create a containment that would leave the space craft unharmed? Do we know of materials that would survive such acceleration?

/sci/ could you explain the hype around black holes to me? I'm dumb but want to be enlightened.

>>3870651

Just what the hell are black holes?

Where the hell does the matter go?

Where does the hole lead to?

Is anyone here that is watching every news about black holes and is really into them?

If someone can come up with a beautiful explanation to my questions, i would be grateful.

Can someone explain to me how gravitational lens work? I've read a few things but for the life of me, I can't figure out how it works ..
It's not like light refraction with water, it's in space.. I don't get it.

ITT, black holes are the most awesome thing in the universe.
