Is rebirth scientifically proven?
Reincarnation as you describe it, is scientifically unproven. It is also, speaking as a scientist and someone who has studied &amp; researched Buddhism for almost 30 years now, IMHO irrelevant to the central teaching of Buddhism, which is experiential. Buddhism and science agree on many aspects of how the brain and the mind operate. The meditative practice and mental effects of Buddhism can be and have been scientifically quantified.
Many Buddhist schools also do not perceive reincarnation as the definition in your question, but rather as an allegory for the states of mind we go through as individuals every day. One Zen master wrote &quot;we reincarnate ten thousand times every day&quot; - that is, your mental state is not the same right now as when it was 5 seconds ago. This is viewing the realms of Samsara as states of mind: craving, desire, frustration, bliss, instinct, etc.
