what would happen to a point in space that is moving away from earth at a speed greater then the speed of light? Would that determin the boundry of the observable universe?
-
Very helpful for my exam.
-
@runawaybg That's because the force caused by the gravitational attraction (acceleration) between the Milky Way and Andromeda is bigger than the stetching at this distance.

Now im going to pass my final. Thanks!
-
so if the space is stretching, that means we are stretching too... creepy

This is state tax payer property, not proprietary insight. I demand 5000$ from Nasa in small claims court. No Lawyer needed.

ur a legend! Never knew you could be helpful in my Physics exam as well. Only used your maths videos previously.
Thanks so much! Khanacademy zindabad!

this with the andromeda galaxy is bullshit, that fat thing will collide with our galaxy in millions of years....
-
Sal, you videos are great but this is math, when you watch videos under "cosmetology and astronomy" you expect to see videos teaching you about things that take form in space like learning more about nebula's or something.

Andromeda is not moving away.

This playlist is AWESOME.
Mr Khan, can you also expand your collection of Physics videos into waves and quantum mechanics?
Thank you so much for all your hard work.

Just did little calc. Rougly at distance 13,85 billion light years space is stretching faster than the speed of light then. So i doubt we will see any further as we see now (which was stated in one of the previous videos).
