Will all stars in the universe die eventually?

Posted: 09 Apr 2019 01:30 AM PDT

I always tought that even if a star dies new ones will take its place and this process can go on forever. So will the stars cease to form and every other one will die?

Can you see the rings? Do the moons look as big as ours in our night sky? What's the color of the night sky there?

What happens if you kick a ball in space ?

Posted: 09 Apr 2019 03:34 AM PDT

I am not any professional scientist but I am kinda inquisitive.I was wondering if the laws of newton ( Specifically the first law of motion ) would apply to any object in space.

What would happen if all of the emptiness of space was entirely filled with the air we breathe? Would there be any strange reactions or catastrophic things that would happen?

How do astronomers calculate the orbits of planets?

Posted: 08 Apr 2019 05:04 PM PDT

Is there just one equation that shows where a planet should be or is it more complex than that?

How does the uncertainty principal relate to quantum fields?

Posted: 08 Apr 2019 02:53 PM PDT

The uncertainity principal states that the more you know about the position of a particle the less you know about its momentum and vice versa but that doesn't state anything about fields. The uncertainty principal also has something to do with quantum fluctuations and non commutativity but I don't understand this part of it too well. I know position and momentum don't commute but I am not sure why

How exactly does exercise induced hypoglycaemia occur in Type-1 Diabetics?

Posted: 08 Apr 2019 04:54 PM PDT

There seem to be mixed opinions on this as well as conflicting information on how exercise induced hypoglycaemia is effected by different types of exercise (lower intensity such as jogging and high intensity such as sprinting). Some of the papers I don't have access to, either, which further complicates the topic and makes it difficult to get an overview.

Can anyone help out?

Many thanks!

What results from fusion of He-4 + neutron ?

Posted: 08 Apr 2019 12:40 PM PDT

The following fusion sequence is well known:

deuterium(d) + tritium(t) → helium-5 → helium-4 + neutron

In this process the unstable helium-5 isotope is a required intermediate step in the process, that is, the d+ t fusion event does not go directly to He-4 + n, first a He-5 isotope must be formed.

My first question is, is there experimental evidence for the reverse process ? If yes, during the fusion of He-4 + n is the unstable He-5 isotope observed or does the process go directly to d + t ?

Second question. He-5 is unstable to alpha decay but is there experimental evidence to show that it is stable to beta decay ?

How Does Global Warming Affect Hurricane Strength?

Posted: 08 Apr 2019 05:35 PM PDT

Does a hurricanes strength increase from higher ocean temperatures alone, or does it require an increase in the difference between ocean water temperatures and the hurricane system itself? If the latter is true does that mean that average ocean temperatures will increase faster than average air temperature?
