What do you find most puzzling about white supremacists?

Is a telescope an okay birthday gift for an 11-year-old boy?

I have a 4 year old grandson soon to be 5. My wife bought him a small pair of binoculars. At first when he looked through them he couldn’t see anything, but he kept trying and all of a sudden he said, “Woa! Everything’s big!”

Then he wanted to look at everything inside and outside the house through the binoculars.

I don’t think they’ll last long though, because he won’t take them off and I’m pretty sure he’s going to accidently break them because this is the coolest gift for him! He can’t take them off! And of course he can’t stop running around and playing either. It’s inevitable they’ll break.

We think, however, it’s the best gift we could have given him!

For a telescope, though, I’d recommend a little older kid. Eleven sounds a great age. Once someone can spot Saturn’s rings in a telescope for the first time, they will be hooked.

That being said, I know some people who couldn’t give a care in the world about that irrelevant eclipse that recently took place in North America. They don’t need a telescope.

What if the aliens visited earth and they were friendly?

trapist1That would be fantastic! We should have so many question for them, like how did they manage to cross light years just to get here? Going at the fastest speed ever achieved, it would still take us about 1,500 years one way to reach the Trappist-1 system 40 light years away. Many people have no concept of the impossible vastness of space. It is more than likely they would be coming from a more distant planet, perhaps thousands of light years away, something that would take a lot of lifetimes to traverse. Did they travel on a multi-generational ship, maintaining a whole civilization on board, or did they go to sleep in some kind of suspended animation? How are they going to get back or send word to their people that we are here, since radio signals might take thousands of years to get back to their home planet.

How would the earth and the moon react if Haley’s comet were to pass between them?

No reaction physically. Psychologically we’d be freaked out, but Haley’s comet is a small body that would have little gravitational effect on either large Moon or even larger Earth. It would zip by with no effect except to excite scientists and make headlines.

Why can’t we come to a feasible conclusion on whether aliens exist or not?

Of course we can! The answer is no, there are no aliens from other planets. This is not the answer you wanted, but if you really understood how far a light year is then you would know the very nearest star is 4 light years. Another candidate is 40 light years.

No one can achieve or even approach the speed of light. To go 4 light years at max speed, and then slow down once you got there, would take no less than 150 years each direction.

To go to a more likely candidate Trappist 1 at 40 light years would take 1,500 years each way, whether you were an alien from there or from Earth.

However the chances space dwelling entities live so close is unlikely.

The more likely distances are thousands or millions of light years away.
