Science will sort that out as long as we don't destroy ourselves first.

There is a pretty good chance that we will destroy ourselves although life does have ways of resisting what wants to kill it but science can't increase the speed of light and that one is a real bummer. The closest star to Earth is 4.244 light years away meaning a roundtrip will take 8.488 years if transport can be used that will go that fast.

Humans may eventually be able to become robots with brains and live a long time.

"Destroying ourselves"

 An astronomical event could do that.

"The closest star to Earth is 4.244 light years away "

The current state of physics suggests we will never exceed the speed of light, but new discoveries and new understandings have already happened. For example quantum entanglement occurs at least 4 times the speed of light and is probably faster. The invention of the Attoclock in 2014 allows us to measure the speed of quantum tunneling, but wasn't possible before that.

It used to be believed that the Hubble Constant was a limiting factor in the expansion of the Universe, but we now know the expansion of the Universe is accelerating and we don't really know why.

A human brain inside a mechanical body might happen one day.  You can't rule it out because humans are incredibly inventive.

Carl Sagan wrote a novel called Contact about the existence of worm holes to connect distant stars and galaxies. And there is Brane-String theory. https://svs.gsfc.nasa.gov/10137

One of my interests. I was a mad astronomer when I was a teenager but sadly my math wasn't good enough to do a degree in it. However I keep my hand in by reading what I can in the field. There are a lot of theories about how the Universe is 'constructed'. How it looks is not how it is.

As a ten year old, astronomy was my first love and then I added other sciences. I still think gravity is the most curious force of all.

My math was great until calculus. I had difficulty grasping the f of x.

I sympathise. I can remember getting a Teach Yourself Calculus book from the local library. I gave up on it.

In the Seventh grade in Crisp county in the US state of Georgia, my teacher asked us all to figure out the velocity of the Earth around the sun knowing that the distance to the sun was 93 million miles and I was the only pupil who came up with the answer. My math skills were advanced for my age but then came calculus. Half of the students in my class in college failed including me while the calculus class taught by another teacher in another class had very few fail showing that the teacher of calculus means a lot.

I think there is a trick to learning calculus and I never understood the trick.

The Tom Hanks movie "Hidden Figures" had a black woman explain the trick was in reducing one side of an equation to zero.

Enjoyed Geometry.

Algebra was a mystery but I didn't pay attention so that was my fault.

Algebra was very easy for me. Geometry was OK but I never got into the proving theorems part. It seemed like a waste of time. Geometry is the trainer for trigonometry which is fundamental for engineers. I come from a family of engineers.

My love in high school was really meteorology which has been my hobby most of my life.
