Ask Ethan: Can quantum entanglement survive a black hole?

Quantum entanglement links information between particles across space and time. So what happens when one of them falls into a black hole?

Can quantum entanglement survive a black hole?

#AskEthan

When one member of an entangled pair of particles falls into the black hole, is the entanglement broken?

And if not, is there any way to test and confirm its persistence?

Will anything persist when the Universe dies? #AskEthan The last star will burn out, the last black hole will decay, and entropy will reach its maximum: a heat death. After all that, can any trace of our existence still persist? bigthink.com/starts-with-... #space #cosmology #fate #astro

Ask Ethan: Will anything persist when the Universe dies?

Long after the last star burns out, the Universe will experience its end state: a heat death. Will everything prior then be meaningless?

Will anything persist when the Universe dies?

#AskEthan

The last star will burn out, the last black hole will decay, and entropy will reach its maximum: a heat death.

After all that, can any trace of our existence still persist?

Can we see the expanding Universe changing? #AskEthan We've measured the expanding Universe by looking at many objects at different distances and with different redshifts. Here's how we'll measure it directly: with just one object over time. bigthink.com/starts-with-... #space #astro #redshift

Ask Ethan: Can we see the expanding Universe changing?

The Universe is expanding, the expansion is accelerating, and some galaxies even recede faster-than-light. Can we see a change in real time?

#AskEthan

We've measured the expanding Universe by looking at many objects at different distances and with different redshifts.

Here's how we'll measure it directly: with just one object over time.

How long can the longest-lived star shine? #AskEthan It's been 13.8 billion years since the Big Bang, but the longest-lived stars will shine for many trillions of years. How long do we have before the last survivor goes out? bigthink.com/starts-with-... #space #astro #stars #future

Ask Ethan: How long can the longest-lived star shine?

13.8 billion years have passed since the Big Bang, but many stars will survive for longer than that. What's the longest-lived a star can be?

#AskEthan

It's been 13.8 billion years since the Big Bang, but the longest-lived stars will shine for many trillions of years.

How much damage could a cosmic ray do to a human? #AskEthan Cosmic rays come in all varieties of energy and speed, with the most energetic ones outstripping even LHC protons by a factor of millions. What would happen if one hit you? bigthink.com/starts-with-... #space #astro #physics #particle

Ask Ethan: How much damage could a cosmic ray do to a human?

At the upper limits of what's energetically possible, cosmic rays still persist. What happens if a human gets hit by the most energetic one?
