    Good luck with your project, Peter. Black holes are fascinating.

    I If the universe is truly infinite in size...

    The theory is that our universe started with the Big Bang. You're now saying it's possible the entire universe could have started infinite. If so. then how was the infinite universe started?

    Mind boggling machine learning results from AlphaZero

    I love chess. But I don't see the appeal in playing a game against a machine, knowing you're going to lose. Chess is an exercise for the mind. There is no benefit knowing the inevitable outcome is failure. I do, however, see a huge significance for science. Imagine a machine that can tell...

    Great information, everyone.

    B Age of the universe: observable or entire universe?

    Is there any genuine proof of the 'Big Bang Theory' or are we dealing with, as the name says, merely a theory? Is there anything to prove what was here before the BBT? I keep thinking of hypothesis through the ages, ie; the world was flat, the earth was the center of the universe, etc., etc...

    5.8 Magnitude earthquake hits Montana

    In the early '80s, an earthquake hit Oregon (I believe it destroyed a school) and it was felt with a strong force in Montana. I remember it clearly. Our entire house rocked. We were in Kalispell (northwest), Montana.

    Another Earth-like system near us

    Just an out-there question. Is it possible another earth could be in our own orbit in such a position that we never see it?

    A LIGO Was It All Just Noise?

    Since the black hole merger was a billion light years away, isn't it probable the event actually happened a billion or millions of light years ago?

    Should we invest in Mars Exploration

    I don't see a real purpose. Mars is pretty much a dead planet. True, there may be water beneath the surface, but nothing grows. I think most of us believe that Mars may have thrive at one time. millions or even billions of years ago, but it's pretty useless now. I don't see a real reason to...

    I Space station artificial gravity - how to spin up to speed?

    Has anyone considered doing penetrating ground radar? Is it possible the moon or mars has fossil fuel like we do? If so couldn't that be used to run the artificial gravity mechanism?

    Ideas for refrigerator door design

    The idea of glass doors is so-so. As a woman and a mom who raised a lot of children (and cooked a gillion meals) those would be okay, but there are more important things to women of any age; pull out shelves and drawers in both fridge and freezer, or even revolving shelves. Most women face...

    What kind of fossil is this or is it a fossil

    I think it looks like veins of some kind of metal. I'm pretty sure it's not a fossil. But it's a cool rock. I would have kept it, too.

    B Black Holes & Dark Energy

    I wonder if science and/or industry will ever be able to create a video camera that would remain intact so we can find out exactly what happens inside, or what causes black holes or spheres.

    I What would it take to hear the Sun's sound from Earth?

    Would it be possible, on one of the space missions, say to Venus or Mercury, to get close enough to record the sound of the Sun more vividly?

    Physics Can someone help me tell whether Physics is right for me?

    As long as you're wasting time pondering what to do, you're getting nowhere. Take the first step. Go to a college guidance counselor, and listen to his/her suggestions. Then pick a class or two. You won't get anywhere if you don't DO something. If the path you decided on doesn't feel right...

    I Thoughts on Breakthrough Starshot?

    Sorry, rotating was just the best word I could find to describe what I meant. Thanks for the clarification.

    I Thoughts on Breakthrough Starshot?

    I've always had a vision of a ring-like ship that has a powerful center generator that creates its own power, by simply rotating rapidly, causing electricity and immense power. The only time any other source needed would be on take off and landing.

    B Where is the void?

    A simple question, hopes for a simple answer. Is the Big Bang a theory, or hypothesis, or is there irrefutable proof?

    Did hunter gatherers work less or more than modern humans?

    They worked less, but their work was generally harder. The men hunted. They did not plant because they were 'hunter-gatherers'. While the men hunted which wouldn't have been every day, the women gathered the berries, nuts, fruit, whatever was in season. But the work wasn't over for either...

    I Spacetime and effects of being super close to the Sun

    This is just a thought that popped into my head (these may not be in the correct order). We used to believed the sun rotated around us. We believed the earth was flat. Then we discovered planets and realized we all rotated around the sun. Then we learned the earth was round. Then we...

    Distance of horizon

    I can't really see how an accurate distance can be defined, since the horizon moves with you.

    Did hunter gatherers work less or more than modern humans?

    If they made it to parenthood, the life span grew. Because once their offspring became of age to hunt, they took over the 'family business'. But the longevity of life was short for the most part, any thing from an accident to a cold or pneumonia could cost them their lives. No medicine, no...

    Did hunter gatherers work less or more than modern humans?

    I believe they worked less. The men went hunting as a group (like you guys with your buddies), they killed and cleaned their prey, then brought it home for the women to cook or store. They had no stress (except in winter when food was getting short), and they spent the evening hours with their...

    I Two black holes colliding - visual

    As a layman, I would think the two holes would resist each other. Assuming the are pulling with equal force gravity, I think they would remain in a stale-mate situation until they drifted by each other. If one was stronger, it would simply devour the weaker one.
