Betelgeuse going supernova one day. That shits supposed to be brighter than the moon for several weeks and will even be visible in the day time. Gonna be so cool. Just imagine seeing it hen it actually happens. Just looking into the sky and seeing this silent space explosion come up out of nowhere.
Imagine the science news websites trying to do damage control so people don't think the world is ending.

The supernova isn't going to harm us. It is much too far away. It is just going to be a spectacular show and nothing more

And the sad thing is we won't be around to see it.
We don't know that. We don't know exactly when it will blow. It could blow sooner or later.

It could have already blown but the light has yet to reach us.

I'm aware of that. I think it's kind of sad that so much has happened in space that we don't even know about because the light hasn't reached us yet.

White holes are theoretically impossible, but we believe one managed to occur.

The great attractor cannot be seen...

Take Andromeda for example, we are seeing it as it were 2.5 million years ago.

I find it interesting how much space changes when you use a different system of measurement.

This is true, as Baconshelf mentioned earlier in the thread, the universe would just.... start repeating itself at some point.

In a few billion years, the universe will expand to the point where everything is so far apart and used up that no stars or well... pretty much anything will be able to form

It'd be eternal darkness

Pretty depressing

Is that what they think the great attractor is? Last I heard they thought it was a separate space time outside ours affecting our's gravitationally.

Not in a "few billion". We are talking about the upper estimate of 10^10^120 here. Also, quantum tunneling may bring the universe back into a pre big bang state, restarting the process, albeit after a massive timescale.

About a year ago, they believed it is a cluster of mass they are unable to detect, due to our own galaxy's stars blocking it. However, they are able to utilize the gravitational lens of it to a degree.

The universe will be viable for life as we know it(used loosely) for another couple trillion years.

when you think about it, gas giants are really just rocky planets with really big atmospheres

clum clum · February 23, 2015, 07:04:01 PM

If protons don't decay, all baryonic matter will decay into iron-56 after about 10^1500 years. The black hole era (the point in which the only things in the universe are black holes) would have ended at this point. This would be a small spike of activity in the empty universe, with stars returning in the form of iron stars.

And the only reason their atmospheres are so big are because the rocky bits are massive enough to gravitationally capture free hydrogen and helium.

I just want to point out that just because something's infinite doesn't mean there exists all possible combinations of events. For instance, an infinite string of numbers, such as pi, by no means contains all combinations of numbers.

life could've developed as early as 10 million years after the big bang

A magnetar has such a powerful magnetic field that it would suck the iron out of your blood from thousands of miles away

Magnetars magnetic fields are so powerful that they would be visible to the naked eye.
