Ancient Life as Old as the Universe

One of the main ideas explained in this video is that the very early universe (i.e. the universe “right after the Big Bang” in cosmic timescales) might have been habitable for a short period of time. During this time window, the right temperature to support life wouldn’t have been restricted to the proximity of stars, but would have instead taken place absolutely everywhere in space due to the intrinsic temperature of the universe itself. link ▶ this video

Not before the Big Bang, but this is interesting -- what if life developed when the entire universe was in the habitable zone? ▶ this video

> offering more evidence for the theory that life on Earth was seeded from outer space. This hypothesis seems to be getting more and more traction. There is an excellent recent video on topic from Kurzgesagt [0]. Interesting that neither the video nor the article uses the name panspermia[1] to refer to the hypothesis. I wonder why that is. Wikipedia also states that "[the fringe theory] is also criticized because it cannot be tested experimentally". Can't it? If we ever find an organism based on DNA compatible with organisms on Earth, wouldn't that validate it? [0] ▶ this video [1] link

Kurzgesagt just posted a video that speculates that life was possible every where when the entire universe was at the temperature range of liquid water as it cooled after the big bang. ▶ this video
