Bump for the best page I’ve seen in a while
That is an awesome site!
I suspect they are failed stars, like our own Jupiter...
It would be red though...
Space itself is expanding, pretty much anywhere is the center, if it started at a point.
OTOH, the Magellanic Clouds pulse in and out orbiting a common center, an observer in one of the clouds taking a snapshot at the right time could conclude that it all had to start at a single point in the dim past.
Maybe it wasn't a bang, but a continuous low frequency hum.
The 'energy' to make the stars shine, and build new stars would need to be constant.
The same energy that holds the atoms together holds the galaxies together.
That energy source 'started up' and has been continuous ever since. Without it, the atoms dissemble and the Universe becomes a void without form.
The Big Bang provides no explanation for why new stars can be created after they burn out.
The reason most of our theories about the Universe stay theories, is because the are usually wrong, in one way or another.
Fifty years ago, we were completely sure that our Galaxy was THE UNIVERSE.
Well...not infinite. Just a lot.
and they are all moving, and scientists now favor the idea that a wandering planet entered our solar system and crashed into at least one planet.
Sure, a typical wandering Jupiter-size planet will eventually wander close to a star...but the universe has only been around for 13.75 gigayears (give or take). Eventually most stars & planets in our galaxy will either drift towards the central black hole at the core, or be flung out of the galaxy altogether through gravitationally close encounters with other stars (a process called evaporation, IIRC). But this will take a long time, trillions to quadrillions of years.
The Earth is pelted with tons of space dust and ice crystals every day. Just because we don't see it doesn't mean it doesn't happen.
Certainly...but we only get hit by something the size of the dinosaur-killer asteroid (about 5 to 10 miles wide) every couple of hundred million years on average.
There is no center. There is no "point" at which it all started. See http://www.astro.ucla.edu/~wright/nocenter.html
I guess it depends on one's interpretation of 'space', but I see no proof anywhere that 'space' is moving anywhere.
How can one measure the speed of objects in the Universe, if the Universe itself it moving ?
Women and Minorities Hardest Hit
Well, a rotating black hole (one with angular momentum) would have a ring-shaped singularity instead of a point-shaped one...but you would still experience spaghettification. Interestingly, the larger the black hole the less severe the tidal forces you would experience as you approach it...they're more "spread out", so to speak. I believe you could actually approach the event horizon of the black hole at the core of the Milky Way (4.1 million solar masses, BTW) without being torn apart to you component particles.
You'd still be toast, of course :-)
If you'd like to read some novels that deal with this, check out the works of Stephen Baxter. Specifically, uch of his novel "Exultant" is set at the super-massive black hole at the core of the Milky Way.
I looked it up as well because it was not a familiar passage.
I think that would fall under the “[Dan] Rather true” scale of “fake but accurate”.
Sorry I was so wordy and unclear.
Let me rephrase.
The amount of stars and planets in the known Universe is so large, and the Universe so large, that there are probably millions of such crashes every day. Somewhere.
Very philosophical - why SHOULD there be a “point” (or reason) to the universe if there isn’t a Creator?
ah, but have YOU examined all evidence to the contrary showing a young universe? Are you even aware of such evidence?
The formation of new stars has nothing to do with the Big Bang. See: http://en.wikipedia.org/wiki/Star_formation
Fifty years ago, we were completely sure that our Galaxy was THE UNIVERSE.
It's actually been almost 90 years since this has been shown not to be the case: http://en.wikipedia.org/wiki/Edwin_Hubble#The_Universe_goes_beyond_the_Milky_Way_galaxy
It's hard to assign a number, but there's no doubt that such collisions happen on regular basis when the universe as a whole is taken into account, yes.
There is no expansion, either.
Yet new stars are created every day, full of energy and life.
What creates them? Creation requires energy.
When I typed that, I thought I was probably off on the years.
Thank you for correcting that. And for the conversation .
