All Things Space

Big news today, an explanation (and discovery?) of wormholes, that also explains gravity. I'm still trying to comprehend this I'm not at all familiar with general relativity or anything beyond basic physics

it looks like they are using blackholes and wormholes to explain the instant communication and the instant reactions of quarks. this behavior has been known for some time, but it looks like you linked some new explanations of said behavior.

interesting stuff but not exactly light reading lol.

Seems more to me that they are using a known theory to explain something they completely don't understand. I know this is the most logical step, but it doesn't seem like it's based on actual evidence, more of a "well, this might make sense given what we know", which does actually make sense...but doesn't sound statistically like it would be right.

Space is such a mind fuck.

Bravo to everyone in here. I love reading up on the universe, it's just one giant mind fuck.

wow. fuck chemistry

Why is nobody talking about the new planet they discovered with the most distant orbit from a star? Planet is 11 times the size of Jupiter. That's insane.

So post some info on it

^ I find Venus to be highly captivating. It's such a mystery. Kind of like a really hot science babe.

I'm still waiting to see evidence of a black hole existing outside mathematical formulas, namely some sort of direct observation. I know I heard somewhere scientists thought they were getting close to that...but still no dice. Seeing a specific object actually disappear would be helpful to such a bizarre conceptual space phenomena.

There are videos of stars orbiting the black hole at the center of the Milky Way. I think it was compiled from like 15-20 years of pictures of the stars movement. If I remember correctly, one star does a full orbit in about 6-7 years. Pretty cool video (couldn't find it on youtube.

My beef with black holes...

They say light can't even escape its gravitational pull. That nothing can. However, multiple photos claimed to be super massive black holes show case two emitters emitting radiation from the black hole.

How does that work?

When a black hole that is rotating quickly swallows a star, the rotation can cause some of the stars mass to travel near the event horizon and escape from the poles. A black hole spinning fast enough does some crazy things.

what happens to said star?

Most of the matter is swallowed by the star, but a small portion (5-10%) is ejected.

One spinning fast enough can theoretically expose the underlying singularity. In just the right conditions a black hole can end up ring shaped and the event horizon can collapse into itself leading to a naked singularity. It's one of those things that they don't know if they can actually exist or not. The math says they can and they've done computer simulations that show how one can form, but they don't know if those conditions can arise in the real world. Suffice to say spinning black holes are very, very strange.

Check the second vid in post #173

More fun info. Surprising how accurate some people 300-400 years ago were in regard to certain observations.

Nice.

Black holes have got to be the single most interesting thing in the universe. If money was no object I would have gone the physics rout instead of boring ass engineering.

One of my old HS classmates graduated like No 1 or 2 in the class, then went on to University of Chicago for physics, ended up landing a job at Fermi lab as a researcher and hated it lol. Now he is teaching physics at a Chicago public high school while he persues another degree. You probably made the right choice

An international team of astronomers, led by a University of Arizona graduate student, has discovered the most distantly orbiting planet found to date around a single, sun-like star. It is the first exoplanet -- a planet outside of our solar system -- discovered at the UA.

Weighing in at 11 times Jupiter's mass and orbiting its star at 650 times the average Earth-Sun distance, planet HD 106906 b is unlike anything in our own Solar System and throws a wrench in planet formation theories.

"This system is especially fascinating because no model of either planet or star formation fully explains what we see," said Vanessa Bailey, who led the research. Bailey is a fifth-year graduate student in the UA's Department of Astronomy.

We might find that there are many different ways that planetary systems can form and change as the various bodies gravitational pulls inter-react. The wobble method may not be totally accurate if there are multiple bodies influencing the star being studied. Some assume our solar system is the normal way a system forms. There may not be a normal system as each forms under different conditions.
