Does energy has gravity?

[Braznor]

Inquiring minds will like to know. Any good explanation here please?

Yes it does

Does OT have English?

 

[her209]

No it doesn't.

 

[fatpat268]

Yes it does

No it doesn't.

Ok... Fight!

no

Only if it's treadmill energy. That's what keeps the plane from taking off.

 

[DrPizza]

Yes, as energy can behave as mass. i.e. in one form, it's called stored chemical energy. When energy is given off by an exothermic reaction, mass is lost according to E=mc². Chemistry majors say "conservation of mass!" but that's only a very very close approximation.

If you want to go into more depth, explore why the mass of a proton is much greater than the mass of the three quarks (Up, Up, and Down) that make up a proton.

Yes energy, especially electomagnetic waves are distorted by gravitational fields.

No,but force has power.

 

[Fritzo]

Gravity is actually the distortion of space by mass. It isn't something that can have energy per se.

 

[Paul98]

Not exactly sure what you asking. But if you are asking if energy changes a gravitational field like mass does then yes.

I think he is asking if "energy" "has" gravity the same way mass does. He doesn't say what kind of energy, so let's stick to electrical.

No. Electricity has no mass thus it has no gravity.

Electricity? I am guessing you mean something like electrons and protons. They both have mass, so they obviously "create gravity".

But even something like light "creates gravity", even though it doesn't have mass.

If a particle accelerates to 99.999999999999% of the speed of light. Would the increased mass make it collapse into a black hole?

No, the energy requirements to accelerate it that fast increase exponentially the faster a particle goes.

Smashing two particles together going that fast could create a "micro-black hole" because the masses of the two would hit with such force that they would cause a collapse. These tiny black holes would evaporate nearly instantaneously due to Hawking radiation.

This was the big scare from dimwits after the LHC started up. They heard "OMG! EVIL SCIENTISTS ARE MAKING BLACK HOLES ON EARTH!!!" and caused a lot of fear mongering. In reality if high energy particle collisions were dangerous the Earth wouldn't be here - Reactions magnitudes more powerful occur in our upper atmosphere every day from cosmic rays.

Now that I'm not on my iPhone I'll post a slightly longer answer.

Energy affects the stress-energy tensor which is what causes gravity in the Einstein field equations. Add energy to an area of space, and you increase the gravity there.

The stress–energy tensor (sometimes stress–energy–momentum tensor) is a tensor quantity in physics that describes the density and flux of energy and momentum in spacetime, generalizing the stress tensor of Newtonian physics. It is an attribute of matter, radiation, and non-gravitational force fields. The stress-energy tensor is the source of the gravitational field in the Einstein field equations of general relativity, just as mass is the source of such a field in Newtonian gravity.
