Adam Frank: 我认为宇宙中存在其他生命,但我们目前还无法确定。宇宙的广阔性以及我们对宜居行星数量的了解,都暗示着生命可能存在于其他星球上。然而,我们不知道智慧文明出现的概率,这需要进一步的研究。我们现在有能力观测到40光年外行星的大气成分,这令人惊叹。我们应该区分生命和智慧生命,地球上生命出现后,经过35亿年的进化才出现智慧生命。地球上出现多细胞生命和复杂生命,需要一系列特定的过程,例如氧气的产生和板块构造。我们现在可以寻找地外生命的生物特征和技术特征,例如大气成分、城市灯光、人造卫星和太空垃圾等。费米悖论中关于我们尚未发现地外文明的论点是站不住脚的,因为我们实际上并没有进行充分的搜寻。寻找地外文明应该关注其他星球,而不是地球。我们对宇宙的探索非常有限,所以尚未发现地外文明并不意味着它们不存在。在未来,我们很可能遇到比人类文明古老得多的地外文明。关于不明飞行物的很多说法缺乏证据支持,仅仅是道听途说。对不明飞行物视频的科学分析需要原始素材和完整的背景信息。大多数不明飞行物目击事件都可以解释。人们对外星人的报道可能源于对未知的恐惧和好奇。我对人类的未来持乐观态度,因为人类具有适应性和韧性。气候变化等问题对人类文明构成挑战,但人类也具有应对挑战的能力。探索地外文明有助于我们寻找解决地球问题的方案。人类活动对地球环境的影响可能是一种普遍现象。我们还不确定长期可持续的技术文明是否普遍存在。 Mayim Bialik: 我们应该探讨外星生命是否存在,以及其他星球上是否存在我们生存所需的信息。科学家们正在积极探索其他星球上的生命。我们是否孤独,目前尚不清楚,但宇宙的广阔性暗示着可能存在其他生命。即使是发现微生物生命,也足以证明宇宙中存在其他生命形式。我们应该探讨如何探测能够访问地球的智慧生命。基于宇宙的广阔性和已发现的行星数量,我们并非宇宙中唯一的生命。我们存在的本身就证明了生命能够在其他星球上出现。在未来,我们可能能够探测到地外生命,但不太可能成为多星球物种。人们对宇宙中存在其他生命的直觉可能并非空穴来风。 Jonathan Cohen: 宇宙空间非常巨大,难以理解。理解星际间的巨大距离对于理解宇宙中的生命至关重要。

Deep Dive

Chapters
This chapter explores the vastness of the universe and the sheer number of potentially habitable planets. It discusses the challenges of estimating the probability of life existing elsewhere and the implications of the universe's size for the likelihood of encountering other civilizations.
  • 10 billion trillion habitable planets in the universe
  • Every star has a family of worlds orbiting it
  • 400 billion stars in our galaxy alone
  • The probability of us being alone is incredibly low unless every other experiment in the universe failed

Are UAPs real? Is an extraterrestrial sighting even possible on Earth? What are the scientific explanations for alien sightings? Is a human-like civilization possible on another planet?

 

Astronomer and astrophysicist Adam Frank (author of Little Book of Aliens) joins Mayim and Jonathan for an MBB Explores to discuss the scientific possibilities of aliens, UFOs, and why we all need to be more excited about what recent technological advances are enabling us to discover in space. Adam Frank discusses his feelings on the government reports on Unidentified Aerial Phenomenon (UAPs), his and fellow scientists' analysis of UFO videos, and why SETI (Search for Extraterrestrial Intelligence) took so long to be funded and taken seriously. Find out the staggering percentage of planets that likely hold potential for intelligent life and why we all feel such wonder looking at the stars. Plus, Adam Frank discusses his time consulting on Marvel's “Dr. Strange” and his feelings on the possibility of a metaverse in real life. You don’t want to miss this mind-blowing exploration of what space has to offer!
