TIL: Myteries Of The Universe

in til •  3 years ago  (edited)

Scientist ask:
Will the universe go on expanding forever,
or will it eventually begin to shrink and end in a Big Crunch?
At present, the answer is unknown, but it seems that the universe may be delicately balanced between the two options. Another question is: does life exist elsewhere in the universe? Again, the answer is not yet known, but the evidence suggests that life may be common throughout space. Space probes sent to other planets search for water, the main ingredient that supports life as we known it. Over 90 percent of the universe consists of dark energy, which cannot be seen. The composition of this remains another great mystery.

Interesting questions for sure. Thanks for the info.

No problem sharing is caring :)

Dark matter is actually only 26 % of the universe. It should not be confused with dark energy that is different.

Sorry bout that :)
Dark matter is actually 25%. Feel free to correct me if you have any corrections after all we all have an equal say.

26.8% to be precise, when you account for Planck data. I am not aware of any update of that number. Do you have some references pointing out towards the 25% number (which is closer to the pre-Planck data, possibly pre-WMAP data).

I got some videos here regarding dark matter and dark energy that i downloaded from youtube :)

Check the dates. Planck data is from 2015 and we learned from there that the amount of dark matter is slightly different from what we thought before Planck. I maintain my numbers :)

It maybe because of the new universe created by dark energy that's why dark matter has grown even more :)
Well as of now we dont exactly know the amount of dark matter maybe the amount has increase again maybe not. We dont know haha

I am answering here because of the nesting limit.

If you assume the presence of dark matter in the universe, then you know its amount exactly. Cosmology allows you to make the calculations. You can fit the parameters of the cosmological model according to the latest data, and you get 26.8%.

This may change in the light of new data of course, as there are uncertainties. But give or take it will not be very different from this number (otherwise new data may contradict old data).
