If you consider a volume of absolutely empty space without energy, mass or particles it exists but can not be observed because there is nothing there. So the short answer to your question is that the empty space-time itself exists without energy/mass.

Can something exist without mass?
If a particle has no mass (m = 0) and is at rest (p = 0), then the total energy is zero (E = 0). But an object with zero energy and zero mass is nothing at all. Therefore, if an object with no mass is to physically exist, it can never be at rest.
How does a photon exist if it has no mass?
Why do photons have no mass? In short, the special theory of relativity predicts that photons do not have mass simply because they travel at the speed of light. This is also backed up by the theory of quantum electrodynamics, which predicts that photons cannot have mass as a result of U(1) -gauge symmetry.
Is there energy without matter?
Radio waves, light, and other forms of radiation all have energy, but do not need matter. So yes, you absolutely can have energy without matter, in empty space.
Does mass require energy?
Relativistic mass is equivalent to energy, which is why relativistic mass is not a commonly used term nowadays. In the modern view “mass” is not equivalent to energy; mass is just that part of the energy of a body which is not kinetic energy. Mass is independent of velocity whereas energy is not.
How does energy exist if it Cannot be created?
First Law of Thermodynamics: Energy can be changed from one form to another, but it cannot be created or destroyed. The total amount of energy and matter in the Universe remains constant, merely changing from one form to another.
Does energy actually exist?
Energy isn’t actually real—it’s just a way for us to keep track of interactions. (Humans deal with stuff that isn’t real all the time. Words—words aren’t “real,” they are just ways that one human can share an idea with other humans.)
How does energy exist?
It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. After it has been transferred, energy is always designated according to its nature.
Are humans matter or energy?
In life, the human body comprises matter and energy. That energy is both electrical (impulses and signals) and chemical (reactions). The same can be said about plants, which are powered by photosynthesis, a process that allows them to generate energy from sunlight.
Do babies create matter?
everytime a baby is born thats not matter being created. Right. As they told/meant to you, the baby’s matter comes mostly from what his/her mother ate during the pregnancy.
Why can’t you hold a baby while on your period?
Since mom herself will be back on her period soon, there’s no valid, medically-proven reason that someone’s menstrual cycle would cause any harm to a newborn.
Do babies feel love when you kiss them?
Around the 1-year mark, babies learn affectionate behaviors such as kissing. It starts as an imitative behavior, says Lyness, but as a baby repeats these behaviors and sees that they bring happy responses from the people he’s attached to, he becomes aware that he’s pleasing the people he loves.
Can toddlers sense pregnancy?
Sadly, the answer is no. Even though it’s a beautiful idea that our little ones are so in tune with us that they can sense the hormonal changes that pregnancy triggers, there is no scientific evidence to show that toddlers can sense other babies in the womb.
Why does my 18 month old prefers his dad?
It’s not uncommon for children to prefer one parent over the other. Sometimes this is due to a change in the parenting roles: a move, a new job, bedrest, separation. During these transitions, parents may shift who does bedtime, who gets breakfast, or who is in charge of daycare pickup.
What happens to the sperm when a woman is already pregnant?
Most of it will simply be discharged from the body through the vaginal opening. Thanks to the placenta, amniotic sac, and mucus plug covering the cervix, your baby has a protection system that’s very specific about what goes in and stays out!
Does a toothpaste pregnancy test work?
The toothpaste pregnancy test is not accurate — it cannot detect pregnancy. Doctors do not recommend the use of DIY pregnancy tests such as the toothpaste test. Anyone who thinks that they may be pregnant should use a standard, over-the-counter pregnancy test or see a doctor.
How do I get pregnant?
The sperm and uterus work together to move the sperm towards the fallopian tubes. If an egg is moving through your fallopian tubes at the same time, the sperm and egg can join together. The sperm has up to six days to join with an egg before it dies. When a sperm cell joins with an egg, it’s called fertilization.
Do corner shops sell pregnancy tests UK?
Pregnancy tests are available for purchase in corner stores, gas stations, pharmacies, and supermarkets, but it would seem women are looking elsewhere to find out if they’re expecting a child — about three paces down the toiletries aisle, to be exact.
How much is a pregnant test?
Pregnancy tests are usually inexpensive — they can cost as little as a dollar. Sometimes you can get a free pregnancy test at certain health centers. You can also get a pregnancy test from your nurse or doctor, community clinic, or local Planned Parenthood Health Center.
Can you get pregnant on your period?
A woman’s ovulation cycles can vary, so it’s statistically possible you could become pregnant while on your period. While pregnancy is less likely in the earlier days of your period, the chances increase in the later days.
