This video is NOT intended for metaphysical debates or the validity of the scientific method. I will remove any discussions that are not astronomy related.

I like that we now know that the universe is expanding at an increasing rate due to "dark energy" and that the visible mass in the universe is not enough to account for gravitational effect between the visible mass "dark matter". 20 yrs.later and we have more info and questions about that info than the accumulated knowledge of the past 20k years.

Age of the universe

From Wikipedia, the free encyclopedia

The age of the universe is the time elapsed between the Big Bang and the present day. Current theory and observations suggest that this is between 13.61 and 13.85 billion years

I didnt even watched the video because the vidposter stated that the big bang occured 20 billion years ago when scientists say it happend 13.61 billion years ago. so who do you belive in?

[WarrenChu000]

This video was made in 1978. Since then, the expansion of universe has been discovered to be ACCELERATING - meaning the universe took LESS time to reach the present size. This led to the revision of the age of the universe to be about 13.7 billion years.

[WarrenChu000]

You will note that at 3:00 Dr Krupp said that 20 billion years is an upper limit estimate and may be a few billion years less. Paradoxically, the reasoning for this was that if the expansion of the universe is SLOWING, then the age of the universe would also be LESS than 20 billion years because it was expanding faster in the past and took less time to reach its present size.

the big bang was 13-15 billion years ago not 20

what I like is that back in the days they didn't have deafening explosions in space, like they do now on national geographic or history channel... that's just crappy unscientific bullshit that's fed onto the poor brainless bastards that we now call "the young"...

[salo73]

if we knew, would it matter? consider all the wonderful knowledge that is available, but not a lot of people really care.

[tekatetikitiki]

This "Project Universe" series is from the mid or late seventies...when we did not have the Hubble and Chandra telescopes among other things, SCORPIONFURY...... But most of the contents of the program is still valid....I do not think they knew at that time about gravitational lenses tough

[WarrenChu000]

No, the Big Bang did not expand into SOMETHING. The Big Bang was the expansion of the universe ITSELF. There was no God's view of the Big Bang as shown in the video. We cannot step outside the universe to observe it.
