UC Berkeley Astronomy Professor Chung-Pei Ma shows how spiral galaxies occasionally merge with one another, which, she says, will eventually happen to our own Milky Way Galaxy when it collides with the Andromeda Galaxy.

-----

This program was recorded at the 12th Annual Wonderfest, the San Francisco Bay Area Festival of Science.

Wonderfest's broad goals are best described by its mission statement: Through public discourse about provocative scientific questions, Wonderfest aspires to stimulate curiosity, promote careful reasoning, challenge unexamined beliefs, and encourage life-long learning.

Wonderfest achieves these ends by presenting series of scientific events to the general public. At most of these events, pairs of articulate and accomplished researchers discuss and debate compelling questions at the edge of scientific understanding. - Wonderfest

Chung-Pei Ma is a professor of astronomy at UC Berkeley.

if the sun runs out of fuel, it'll then suck everything up and then eventually turn into a black hole and probably end up sucking the milky way system ( if possible) so Andromeda won't be colliding with Milky way.

Our sun is much too small on a galactic scale to consume the WHOLE galaxy even if it did become a black hole. There are millions to billions of other solar systems with their own suns that make up just 1 galaxy. So to put it simply our sun is but a speck of dust when compared to the Milky Way. There are other black holes in our galaxy right now as well. So while our sun would consume nearby masses it just isn't big enough to consume anything outside of our own solar system more than likely. Btw not nitpicking just offering what little knowledge I have on the subject. :)

it's a star dance

we believe in observation. Use your imagination. Who cares ? Anyone capable of asking why, and motivated to seek answers. What more reason do you need. Who cares if our own solar system died out before hand. It's still beautiful to ponder... This is what makes science amazing...

You seem upset for some reason... but I can't quite tell why from your rambling comment.

what did she just say, 'don't worry about it this will take place in a few BILLION YEARS, that our own solar system would have died and the sun run out of fuel but we like to simulate them'. and then she says this is our future, really who's future if even the solar system would have died by then? this people are super intelligently stupid! Who cares. i guaranteed all of you who believe in the future of outer space and star trek future, IT WILL NEVER HAPPEN! Way too much HOLLYWOOD people! SMH...

Cool

oxygen atoms need an atmosphere. "Space" is a place of no atmosphere.

If you watch VSauce videos, he say that because stars are from a really far distance, so i don't think that some stars would collide.

so even if you clap your hands in space, it will be impossible to hear?

Um.yeah ok.
