Today's nuclear reactors break apart big atoms and energy to heat steam and turn electric generators for our use. That's by the process of nuclear fission.
Scientists have been working for over 50 years to try and sustain nuclear fusion, or the combining of hydrogen isotopes into helium and energy. As far as I know, there is no success as yet.
Will it ever come to pass? If so, when? Will it really solve all our energy problems if successful?

If matter and energy are connected, and cannot be destroyed, only changed. Why can't holodeck characters come into the real world where food from the replicators can appear out of thin air with substance with nutrional value?

I just thought this would be a fun, but inquiring question. I'm not a science guy, just a trek fan..... and I don't do the dress up thing..... just thought I'd make that clear...... no offence ment to those that do.

Any thoughts on this?

Live Long and Prosper!

At a subatomic level EM force waves could be interfering with one anothers canceling each other out to a great extent. The force that was left would be gravity. It would increase with the mass of an object, and always be weaker than EM force.

I'm not a physics major and I've no idea what the math would look like, but the idea woke me up and I thought I would ask.

If light (or its photons) have a mass how does it travel through glass? What effect does the light or its mass have on the medium through which it travels?

A man (m=85 kg) tries to cross a river by swinging from a 10m long vine. His speed at the bottom of the swing (as he just clears the water) is 8.0 m/s. The man doesn't know that the vine has a breaking strength of 1000N. What calculation would determine if the man makes it safely across the river?

we were able to somehow have a strong and sophisticated enough telescope that could see around the earth as if it were fllat and saw several times the earths circumference.

I am not a scientist, nor learnt in its ways so I do not know exactly how to articulate my question

We can not travel beyond the speed of light, but could we see beyond the speed of light and then see into the future?
Could we perhaps do this with satellites that could act in unison to convey their imagery, thus providing a peak into the future

Oh,i feel stupid,I hope you can discern my novice question

Assuming that it is pure energy transfer, meaning no energy lost to friction, sound energy, heat energy or others. Will the lighter ball rebounce or not? After you have answered, pls check:

==>If you say that it will rebounce, then Newton said that when object A acts a force on object B, object B acts an equal and opposite force on object A. So shouldn't this force and the force the lighter object originally had balance out one another (just like when the two balls are of the same mass).

==>If you say it will not rebounce, then why is it that when you drop a ball on the Earth, it will bounce back to its original height assuming no energy lost when bouncing? Shouldn't it just bounce the amount the Earth moved (which is insignificant to the human eye)?
